I have been running a vortech V2 for about 6 months with a stock clutch but it finally packed it in.

I've noticed since fitting the CC stage 2 that i have a lot of rear axle tramp when it breaks traction (most of the time) :)

Car is only running 7 psi, 255 rear tyres, koni 7's, ground control with eiback 440 lbs rear springs. Konis are adjusted mid way.

Engine & transmission mounts are new OEM (they didnt last long either).

All rear end bushes are stock & in good cond.

Any ideas?

Hey mate, firstly try posting this on the www.s2ki.com forums you will get a lot more help there about this.

So the stage 2 clutch is now the strongest point in your drive line and the diff and gearbox is now the weakest so be careful.

I have a Vortech V2 Ti kit which is going on soon, I'll be running e85 fuel with ID1350 injectors, Walbro 450 fuel pump and the rest is the usual Vortech stuff. However I will be getting a custom 7inch crank pulley and a 3.6 inch Supercharger pulley. This will give me about 16-18psi and launch myself in to the 400hp at the wheels range. Shit will break like diff housing and gearbox if I got a real hardcore clutch. So I need to get stronger diff housings as they are incredibly weak and then take it easy with the gearbox.

Do you have a after market computer for it? I'm going to sell my AEM engine management and buy a Haltech for easier tuning.

Good luck mate!
Mark

have you tried seeing what happens if you use different tyres? Chuck stockies on to see what happens.

Changed rear tyres to Federal’s Ultra High Performance street legal semi-slicks 595RS-R (255-40-17).

Now wheel tramp has completely gone away.

PS grip on these tyres is great!! Unbelievable value at $160 per tyre!!
