b16a2 + m62 supercharger

[jimmorris3]

just thought i would post some pics of my progress with the supercharger build

[raider16v]

Sweet,more pics please :cool:

take it easy :D

Mark.

[jimmorris3]

[pippy]

I like it! Where did u Get that charger from?

[jimmorris3]

its off a merc 230, can pick them up for about 150 but its not an easy project to do it with a shaft like i have, lots of machining!!!! plus you have to reverse the drive

[Kam]

Very nice mate :cool:

This is for your watsons frame isn't it? Are you using a Ford DIS setup? Can't see in the pic

[peaty_34]

beautiful m8, nice to see someone trying something different, more pics please.:)

[pippy]

really really like it good luck with it.

[jimmorris3]

yer watsons frame and ford coil pack... still got loads to do but it looks quite smart in the engine bay, no body mods etc needs , apart from the extended front because of watsons frame , but no big buldges in the bonnet etc is the plan !!!

[jimmorris3]

Just wondering, will I have the first supercharger b16 mini?

[Kam]

In the whole wide world? maybe? :twisted:

Running and on the road? maybe? :lol:

On here with a watsons then probably yeah :lol:

There is B18 on here, its a bit 'extended' though :shock:

Pioneers, gotta love em :cool: and no not the sound company ;)

[jimmorris3]

And its in a pickup, its gotta be the only one haha

[Kam]

You need to get a build diary up on here, even more so as you have some nice additions to your build :cool:

Unless its a super secret build and still under wraps then thats fair enough, but you've already told us a bit now :p

[apbellamy]

Looks good.

How efficient is the charger and how much boost will it run?

[Glenno]

that's abit different! :shock::cool:

can I spy the drive shaft being made from several pieces cap-screwed together or is this the cover for the drive?

interesting.....

[jimmorris3]

No that's the outter sleeve, its in sections so that bearings can be placed along the shaft every 100mm ,

[Glenno]

Nioce! Just a thought (you'll probably get a few when doing new stuff like this) Could you have used a larger diametre, thick walled, hollow drive shaft then you'd have hardly any flex, a simple 2 or 3 bearing support and the ability to transmit higher input torques, but a lesser weighted shaft?
Like I say, just a thought - as the guys have said, its fab to see new stuff like this being done, and in a pickup - this baby will fly!!!!!!!!:-D:-D

[jimmorris3]

Keep suggestions coming I'm only 21 so have a lot to learn, but here's y I did it how I did, space is very limited, and I don't want a shaft spinning at over 10000 rpm without some casing, , secondly the way I have done it, although it looks a bit complex, makes it near on impossible for the shaft to be out of line, the supercharger plate goes where distributor was so that must be square to the crank pulley, the outer shaft attaches onto that making the hole thing spot on, I checked it with a laser guide and it is perfect,

I could have done it easier and have the charger coming out the wing or bonnet, but the way I've done it means no body mods atall, and to be honest I think tge supercharger looks at home where it is, just machining some more parts this weekend, hope to get it mapped up next month,

Feedback and ideas much appriciated! !!!!!!!!

[jimmorris3]

just thought id post some pics of current progress with the charger, getting close now cheers

[billing5]

This is really sweet mate, good job on machining work too :cool:
any pics of the drive belt assembly, how much boost you going to run and which ecu :beer:

[Kam]

bit hard to see on the picture, is that three pulleys on the other side?

[jimmorris3]

Yer 3 pulleys so the charger runs of the back of the belt , turning it clockwise, just machining up a new crank pulley with 6 v's on and ill send a pic with the belt on , going for 10 psi with a charge cooler which will probably reduce that to 9psi, I am running dta with Ford coil pack. cheers for comments , Jim

[Kam]

I'm sure I've seen that on here where somethings running off the back of the belt to get its drive? I'll have a look.....

[Kam]

Sorry no, wasn't on this site

Actually that is for a D series :cool:

[flipflop]

brilliant!! after looking at these pictures i cant help but start looking for space in my engine bay for a upgrade at a later date.
keep us posted!

[Kam]

flips - rotrex supercharger mounted between the front grille and crank pulley in what space you got there, piping upto and around to the inlet (180) will be easier if your alternator aint mounted where the minitec one is.......

Everythings feasible, hard work is just how you want the car to look

[Spiyda]

Looks good,
nice to see someone else doing a supercharged motor !

Don't know if you have incorporated it, but what made a big big difference on our build was incorporating a vacuum operated bypass that directed the excess pumped air around the charge cooler route whenever there is vacuum in the plenum.

Without it, the supercharger could cook eggs when not being driven hard.

[jimmorris3]

Rotrex charger £1500 , m62 charger 100, it was my original plan to do rotted i did post how I was going to do it but price but me off big style, and surely just a standard recirc, dump valve would stop the charger getting warm ? Just take the feed from after the charger cooler ??

[Marcus Nordblom]

looks sweet, which rev band are aiming at? top end, low down?

We are running these rootes chargers at much higher boost than their original applications, and they are very good at making vast amounts of heat...

The problem we had was when off boost, it got very hot.. once you floor it, the temperature falls quite quickly..

It gats so bad that you cannot touch the casing without gloves, and that can't be good for the bearings and oil.

I never really found out the reason for this, but it may be due to the vacuum when off boost, means the air is thin and leads to not conducting the heat away from the charger..

I looked at a recirculating valve, but the ones I saw only helped when the air in the charger was at pressure, and that wasn't when the problem occured.

where they would help is with another issue we had, that when the throttle was closed, the engine would rev up momentarily.. this was due to the volume of high pressure air in the inlet tract. we solved that a different way, by using the fuel cut on the megasquirt to cut the fuel completely on the overrun.. then this excess air with no fuel helps to cool the engine for a split second.

[jimmorris3]

I'm running a m62 not a mini m45, my pulleys are set so that when the engibe is at 8500, the charger is at 12000, so the charger is well within its comfort zone. Will a recirc not be open at idle ? So its pumping the cold boost back.into the inlet of the charger ? Keeping the charger cool is a must on this project to keep it efficient, i dont understnd y vacumm would make it hot,can u explain a little more please Jim

[Spiyda]

Jim,

the way I understand it, the amount of heat generated is more related to the boost pressure than the rpm, so up at 12 psi, you will be making lots of heat.

As far as the hotness at off boost is concerned, I don't undertand fully why this happens, but it does... it must be something to do with the lower pressure air not conducting the heat away from the rotors.. especially when it is stagnant.. the problem got worse when we increased the boost..

ours of course is suck through.. its a different ballgame with blow through...

[jimmorris3]

Been on the web and everyone recommends pressure relief valve where did you get yours from ? Do u use a dumpvalve along side that ?

[apbellamy]

Look into water injection pre-charger.

[Spiyda]

Been on the web and everyone recommends pressure relief valve where did you get yours from ? Do u use a dumpvalve along side that ?

Jim,

I eventually used a BMW throttle body with a Jag vacuum actuator . I originally bought a plastic Peugeot/Citroen valve but wasn't impressed with the quality. I made quite a large diameter valve, but a much smaller one would worj fine. It opens whenever the pressure in the inlet manifold (plenum) is less than atmospheric pressure and lets the air circulate round the charge cooler loop.
We tried a conventional dump valve but it did nothing to improve performance, driveability or cooling.

ps its a pity you are so far away, you could come out in pete's car for a spin with and without the valve connected and with and without the overrun cut-off to see the difference it makes.

[jimmorris3]

So did you ever try out the plastic type, I have seen and upgrade from them in aluminium?

[Spiyda]

So did you ever try out the plastic type, I have seen and upgrade from them in aluminium?

The plastic one would probably work, but it looked as if it would leak a bit and I wasn't taking any chances.. using an old throttle body seemed ideal as it will seal as well as any butterfly can.. it actually didn't take long to make it.. only a couple of hours.. I was going to use an old SU carb for the job, but the BMW throttle body had enough meat on it to machine down for a hose to fit on the opposite end to the flange

I still have the plastic one in a box somewhere

[Spiyda]

ps..

the charger gets so hot (even with the bypass etc.), I would be a bit concerned about the heat with the plastic unit too... its probably designed to withstand the heat, but when you are doing something like this, as you know, you try to remove as many possible issues as possible so that only the ones you haven't thought of are left !

Chris

[jimmorris3]

My charge cooler sits away from the charer so if I had the valve after cooler it wouldnt be near any real heat ? Does that make sense ?

[Spiyda]

sounds good.. and the M62 may run cooler than the M45

the locations vary but the connections we have that work are like this..

I have inlet, throttle body, then it splits into two one side goes through the supercharger, then through the charge cooler to the plenum, the other side goes through the bypass into the plenum .

so when the plenum pressure is below atmospheric and the bypass is open, the effect is that the throttle body is connected straight to the plenum through the bypass.. and the supercharger is pumping air in the loop through the charge cooler .. therby keeping itself cool.. without it only the air that the engine is actually using goes through the charge cooler.

when the air pressure in the plenum approaches atmospheric, the bypass shuts and the air moves through the throttle body into the supercharger, round the charge cooler loop and into the plenum.

[jimmorris3]

I'll have that valve of you if you want to sell it, give me a ring , be good to chat anyway 07816053563

Yeah thats where I got my idea from jim when you posted up about it on here, that machine work you got done is some work but unfortunately thats not something everyone can do or get done easily, the rotrex price is staggeringly high :( but its more off the shelf and a bit more plug n play for most folk to mess around with

I still prefer your way though as it looks uber cool :cool:

[jimmorris3]

I.could always run it for 6 months, then knock a few more :)

[jimmorris3]

took some pics of the pulley i machined , and also the full kit ive built up off the car

[Kam]

That is some top work there :cool:

How far are you from actually testing it out?

[jimmorris3]

Hopefully before Xmas, if all goes well

[Kam]

Wasn't your engine up and running before all this? what spec and figures did you have then, any atall?

Be good to see a comparison when this ones up and running

[jimmorris3]

Yer was on the road till couple of months ago , 170bhp can't remember torque without finding dyno , hopefully get 230-260

[Kam]

260! would it pump out that much with that thing strapped on? :shock:

I thought these were a mild upgrade :lol:

[jimmorris3]

With a good cooling system , it could male 300 bhp

[jimmorris3]

Just a quick update, car is running with charger, sounds evil, !!! Just gotta get the intercooler fitted up , I'm having more trouble getting an intercooler to fit than the charger, , but as far as the sc kit goes, its working fine, , so hopefully updates shouldn't be long , Jim

good skills

[sirkieran_1986]

great stuff . wont one .

[_666_]

make a subframe kit, including everything i need besides the engine itself to fit in a standard roundnose, and ill buy one !

[jimmorris3]

Subframe is a watsons frame and is 80mm extended on front , i could do the supercharger kit tho

[_666_]

so if i was to source a frame that didnt involve extending would it all still fit ?

im considering a conversion but i just want it to be bolt on more or less.. plug and play...

[jimmorris3]

Yer I would have thought so , if u buy a frame that fits standard front you have to cut bulk head , don't quote me on that but think I'm right, you.would just have to.mount the intercooler pipework differently to

[adamb]

We want dyno figures :) awesome job done. How much would you charge to do this to mine? Haha

[sirkieran_1986]

sounds good . wot sort of price we lookin at for yr supercharger kit . i all ready have a b16a2 running in the watsons frame . 185bhp . been great for the last two years . now need to deside which way to go . NOS r supercharge it . r both if i win the lotto . lol .

[jimmorris3]

Um well I'm hoping for 260 whp so bout 290 at flywheel the Jackson kits in a civic make that much with no intercooler, but I will no in bout 3 weeks time when I get it on rollers, , I was thinking bout nos at one point then decided for this the way I see it , power will come in much smoother than turbo or nos , cost wise I'm not sure ill have to work it all out , I would say nitrous or turbo would be cheaper tho ,, jacksons kits are about £3000 , mine won't be near that but just machining costs are bout 700 ill try work it out , jim

i would also be interested aswell depending on costs as that looks like a cracking job you have done there.
quick question which im sure i know the answer to but if i made a airbox/plenum on my throttlebodies would i be able to run the charger through them? im sure i could but just checking.
that is very nice work mate well done

i must be doing something wrong as mine is only running 170bhp and i have itb's
i think we need a dyno day with a few of these vtec mini's as we seem to be getting varied figures. would be good to see a few on the same dyno.

[jimmorris3]

Yer I'm sure that would work the same , ud want to speak to someone who.knows how to boosts throttle bodys, but I've gotta get some testing done first before I start building anymore, can't wait to c how the power is delivered , jim

[miniwade]

i imagine it would be fine as pulsar gtir's run throttle bodies on with a turbo so should be good. if it is anything like the rotrex chargers i have helped fit to clio 172's then the power delivery was very linea and was almost the same shape dyno graph only on a higher scale.
i much prefer superchargers just for the simple reason the put alot less stress on the gearbox as the delivery is alot smoother and doesnt kick in with a hard bang like a turbo and stress gearbox's, clutch's and such like.
admitedly you dont get the same quick feeling as you do from a turbo but still good fun :)

[jimmorris3]

I think a mini with 270bhp will give u a quick feeling , lol

[miniwade]

Lol I think you could be right there :-)
Looking forward to seeing your dyno figures.
What sort of boost are you hoping to run?

[jimmorris3]

Worked the pulleys out to 12 psi , that's if my maths are right , jim

[miniwade]

Worked the pulleys out to 12 psi , that's if my maths are right , jim

That will be good if your right, what sort of pressure can you get away with on these engines before you have to start thinking of forging them?

[jimmorris3]

Well I think about 15 with a good tune, with the pressure drop from intercooler, ill prob have 10 or 11 psi, Jim

talking of which, maybe we should have a club stand at Himley this year ?

[jimmorris3]

When is himley hall , but yer if its mid April or later I should be there and defo get a club stand going , jim

[jimmorris3]

Himley hall is 6th of may , let's do it !!! Club stand !

Himley hall is 6th of may , let's do it !!! Club stand !

I think it just boils down to someone volunteering to organise it...

[jimmorris3]

Wats that involve ?

[Spiyda]

My Guess is

1. start a thread in the members section asking who wants a pass for the day...
2. filling in the details on the online form.. etc
3. sending the tickets out to folks when you get them in the post...

It would need the OK from whoever is the chairman designate ?

Have I missed anything ? anyone ?

[Mintegra]

This is awesome!.... a little crazy but awesome nevertheless!... top work!!! :-D

[mikeb]

top work , fairplay , tried to go down the supercharge route myself a few years ago but gave up as the charger was fouling the suspension turret

[jimmorris3]

Wish me luck , i have the map tomooro morning and mot in afternoon, so hopefully ill post a power chart and mot tomooro not a blown engine of.anything !!!!

[k20/k24 allmotor]

Good luck. I think it well make something like 230hp.

[miniwade]

Good luck and I'm intrigued to see what she will make :-)
The look under the bonnet is worth 50bhp

[jimmorris3]

I'm hoping for 250bhp so well c how it gets on

[jamesfawcett]

good luck jim!!! York Minis vs Beetles next weekend :)

[gadget555]

Good luck with the rr session keep us posted

[jimmorris3]

It made 232 bhp with shit loads of belt slip, the boost started drop off at 6000 and I couldn't put any more tension into the belt, its because its not.got enough belt rap, but ot made 189 torque which is huge compared to 110 when mapped without charger ,
Mot passed just , took it for a drive and its very very quick, not even comparable to how it was , never saw intake temps higher than 52 so I'm.happy with that. Just gotta sort the belt out now !

[GingerMonkey]

good work mate they are real good figures. Look forward to seeing it at a show some time this year if you are doing any.

[miniwade]

Is the belt slip an easy fix?
Good results there mate and I bet it flies :-)

[k20/k24 allmotor]

sheeet that is k24 torque, great results.

welcome to the charger club !

some more idler pulleys needed then ?

btw I found that vacuum valve if you are still interested.. how are you handling the supercahrger cooling when on low throttle settings

Chris

[jimmorris3]

Yer extended front 80mm, hard to notice on a pick up. I got a recirculating dump valve which circulates air when on idle, um belt slip shouldn't be to big off a problem, gonna have a look at it tomooro , but I took it out for a drive and its imence

[jimmorris3]

Btw the engine is totally stock , even stock header and 2 inch exhaust so think power is quite good considering ,

[miniwade]

Btw the engine is totally stock , even stock header and 2 inch exhaust so think power is quite good considering ,

id be well happy with that, get the belt slip sorted and get it back on that dyno :)

[wilp99]

nice, sounds loke fun

[TifosiKev]

That is really impressive. A quick question what gearbox and diff ratio are you running.

[jimmorris3]

I'm running the gearbox out of the b18, so limited slip and I'm pretty sure its the watsons 3.4 dif. I think , hits rev limiter in 5th at 137 on the sat nav anyway

[Paul190181]

Wow this conversion is amazing . When you start making the kits I will be very interested in buying one off you .

[Dubaidaz]

Wow!

Is this an extended front?

I want to fit a turbo under a standard round nose....

[jimmorris3]

Yer but its extended because of the subframe , , you could sit the turbo above gearbox, I did that on a swift gti mini with great results

[Kam]

Fair play jim fair play

Impressed :cool:

[garyshoose]

I'm running the gearbox out of the b18, so limited slip and I'm pretty sure its the watsons 3.4 dif. I think , hits rev limiter in 5th at 137 on the sat nav anyway

It's a standard b18 final drive jim unless you changed it. B18's have long gearing therefore perfect for 13's on a mini, and spot on for turbos & chargers. Nice to see you're still developing it. Looks lovely.

[jimmorris3]

Got the car on a weigh bridge on sat , and it came in at 750 bang on , also took it for another dyno and its making 252bhp now , used those calculator things to work out power to weigh and it said 333bhp per ton, I think that will do nicely :) more than a gt3 rs, just gotta find one now and race it lol

[Mintegra]

more than a gt3 rs, just gotta find one now and race it lol

Awesome!... let us know how you get one when you have found one!....:D

[miniwade]

I bet your happy with those figures you got there,
Mine came in at about 260bhp per tonne so gt3's are out of my league, or are they
Or are they?????
http://www.youtube.com/watch?v=RXhysf5_0Fc

[jimmorris3]

Depends how well they can drive lol , most ppl in any quick cars won't bother , yer your car has been on a bit more of a diet than mine I think , I dunno.where i could loose more weight tho, its either doors or bootlid, which I suppose i could just take off. The watsons rear beam arms look heavy maybe redesign them

[jimmorris3]

Didnt c that video till I relied, ,could you keep.up with him or not ?

The watsons rear beam arms look heavy maybe redesign them
not sure what the watsons rear beams are like, im still running a rear subframe but weighed in at 680kg but i do have fibreglass doors front and carbon fibre bootlid. however i do have a full cage hindering me a little.
i dont know about you but most people want to stare at my car rather than race it.

[miniwade]

Didnt c that video till I relied, ,could you keep.up with him or not ?
he got a much better exit out of the last corner as i had brake issues with the servo sticking so was being over cautious all day so i didnt even try but i would guess up to 100 mph there wouldnt be much in it.
thast was before i had my new cams fit aswell so id be a bit quicker than i was in that vid :)

[jimmorris3]

Yer since I've had the charger they don't really have a choice it sounds like a jet lol

[miniwade]

Yer since I've had the charger they don't really have a choice it sounds like a jet lol
lol, i get the same as soon as they hear the induction noise they dont really bother. im toying with the idea of a low pressure turbo for mine :)

[jimmorris3]

Go for it , its not a huge job to turbo one , if you want a nice easy build tho , don't try Wat i did Haha well happy with it now but thing a turbo would have been easier, but the charger does really suit the engine, if you have the money get a rotrex charger , maybe , just a lil dif then

[miniwade]

my prefered option would be to charge it but like you say they are alot more wore but the power delivery is just like oem but with more power whereas turbos the power comes all at once causing alot more stress one components and more chance of it breaking traction as the power comes all at once.
i helped build a couple of rotrex'd clio 172's for rs tuning and they were awesome :)
not sure there is room for one in the mini engine bay though :(

[jimmorris3]

I think ud do a rotrex install really easy, I went up to tts which are one of the suppliers, you would mount it hanging over the end of the engine, like opposite to how the alternator sits, I was very very close to going for this option , but price of the charger put me off , they saod they would mount it as well depends how.much u got tho, but I think an easyish install

[jimmorris3]

By hanging it there as well it solves the problem of gettin the charger to run clockwise

[miniwade]

By hanging it there as well it solves the problem of gettin the charger to run clockwise
i think like you said the price of the rotrex is quite dear which is what would put me off trying it.
maybe something to think about in the future :)

[jimmorris3]

Put it this way I built my whole kit for the price of a rotrex

[miniwade]

Put it this way I built my whole kit for the price of a rotrex
exactly my point mate, any idea whats a safe power to run on these engines before they need to be forged?
i imagine your power and setup is perfect for the mini

[jimmorris3]

From the research I've done. Looking on forums etc , about 250bhp on stock is safe. Although i have seen higher figures , I run 10psi, I think 250bhp through 2 wheels with no traction control is a good amount, I wouldnt say the limit but not very far off, , all depends on engine condition too I suppose. I would like to c how mine compares to James turbo , be interesting to c quarter mile.times, he does win the HP battle tho

Mines bad enough for traction and I only have 170bhp so you will have fun that's for sure :-)
I'd imagine you would get low 13s or maybe a bit quicker if you get a good run.i think james had a lot of problems getting the power down and didn't like the handling once vtec and turbo kicked in. If I remember correctly he got mid 14s in his which I doubt he will improve on as he's dropped down to 10" wheels now which won't help matters.
I managed a 13.7@102mph in mine in damp conditions and a slipping clutch so I'm sure you will beat that as York isn't a great surface either.

Be nice to get into the 12,s

You'll have to post a video up so we can see and hear the howler, when you going to produce the plans for the kits??? Take some measurements and some part numbers then hey presto away with the mixer. Pay back time for all your hard work!!! Very tidy.

im sure you would get close thats for sure.im aiming for sub 13.5s next time out

[jimmorris3]

I would like to make few kits and share the fun out but I want to get some more miles on the kit , c Wat if any wear occurs, c how bearings cope etc, so maybe after a summer of playing about I might look into it

[wilp99]

if you lowered the cr it would prolly be able to take more hp safer. but id of thought you'd be safe at the 250 mark. i know the crank is good for 500'ish. boosted is nice and makes tons of power, but allmotor is where is where im livin.

just had a play with my cam mount i made to see if it worked and seeing as i hadnt posted any videos since the charger i thought i would , jim

[Jeffreypang911]

fck that is mental! Good job!

[Paul190181]

T
His car is a complete rocket . When u sell the kit would it fit on a b18 . Top quality work by the way .

[jimmorris3]

I dont c y its wouldn't , I dunno if I can make it pay building kits tho

[arterz]

beutifull

[Paul190181]

I wouldn't see why it wouldn't pay , I'd be willing to pay 1500ish for the kit minus the charger . The great bit about it is the performance gains uv got . May pay to just put a thread and see what people would pay for it as its a unique kit .

[jimmorris3]

i would need to check if it did fit ok in a car with other subframes,mine is watsons and it fits perfect but would have to do a trail fitmet on other frames , where are u based Paul , jim

[Paul190181]
