How are you ajusting the weights ?


Itís done by winding the suspension up and down in the corners to transfer the weight around.

Jack, does the car pull to the left under acceleration? Does it then drive straight during gear changes? This has a feeling of torque steer. Every one says sort your suspension settings.

It's the Torsen diff! Seen this so many times now.

Itís worth getting the car set up, it could be poor geometry that is exaggerated by the Torsen.
Mine used to do it because I had a break in my frame, so even after I had the car setup, there would have been flex as I never realised it had broke.
Your becoming obsessed with trying to get everyone to throw their Torsenís in the bin Andrew.

I beg to differ on this. I await the finding from corner weights etc.

The symptoms described here are just how mine drove, and yours too Dan.

Yours had a spun bearing, I wouldnít expect that would help it perform to its fullest.
As I previously mentioned, my subframe had a break in the webbing at the rear, an area Iíve since beefed up, the flex in my frame from that broken webbing is going to upset my geometry in all sorts of ways regardless of how many times I set it up and I believe it would be the same with the Quaife, the car pulled about when I had an open diff and the only time it pulled straight was when I previously repaired the broken webbing in the past, but it didnít last long and Iíve never thought about it again until my recent strip down.
I changed my diff purely on the basis that the Quaife is better but that doesnít mean the Torsen is bad, Gazwad clearly proves it works with a good setup.

It was all over the place during acceleration, also when backing off it wanted to wonder around a bit. Will see what itís like when itís all set up correctly

Dont know much about rover k series. Do they have equal length axles like the honda b16 does?

No. The left one is much shorter.

Which could mean has actual torque steer, Jacks turbo engine was 250nm on his older map I believe, I donít know how much it is since it was re-mapped.
If I was in this situation I would start by having the geometry and corner weights set and then go from there.
You need to decide with the corner weights wether you want it to be optimal with just the driver in the car or with a passenger, the problem with the passenger is they may not always be the same person.
I intend on setting mine up for just myself and then if Iím ever playing with a passenger in the car, Iíll have to accept that the corner weights arenít optimal, I rarely have passengers anyway.

I have to say that's a totally different discussion Dan and if truth be know you may have the seats fully reclined so distribution of weight could be optimised.

So theoretically, the car should naturally pull to the right with an open diff ?? and how does it react with an LSD ???

The Torsen is similar to the Quaife ATB so isnít a true LSD.
When you generate too much torque the Torsen passes the power from side to side to try and re-distribute it which can as I discovered can cause the car to pull both left and right under hard acceleration as the diff passes it from one wheel to the next trying to equal out.

Well on the Rover.75 that this engine has come from, yes they do have the intermediate shaft. Chris tried to uses this on his Mini. It actually won't work as makes the remaining shaft too short to operate the suspension.
