Biturbo's Audi S2

[Biturbo]

start with higher tires pressures and when you have it down with launch settings bring the pressures down.
start at point of wheel spinning/break of traction and work downwards in boost/rpm limit. If you start at point of bogging down with LC and dropped tire pressures you are more likely to break stuff as you work up through launch power and reduce your mechanical sympathy

You will know when you have it. you'll get a howl from the tires throughout launch and it'll feel like a hurried squeeze off the line rather than a jolt and a shove if that makes sense.

Last year I done many runs with 1.6s 60ft,but with bigger turbo settings now different.This is my second time out on track.Hope next time it's come back to 1.6s 60 ft.Tyres pressure was 1bar that about 15psi.

Today done new pb 10.74s@127mph 60ft 1.77s on 048m tires

Time to put some proper drag race slicks.So after 2 weeks vw action in santa pod will be with this

Completely pointless to fit the V8 Torsen diffs anywhere, they can't take any serious power.
You will shatter it on 1st or 2nd launch.

The best in my experience for rear has been the lockable (with a button) diff, and start with it locked. That seems to hold up the best to the abuse, but if you have very sticky tires and sticky glued track, then that can have problems too.

Put the normal torsen from 01E with some mods,and it is a ROCK SOLID!!!!!!!!!

And yes ,PRJ is right! The V8 torsen is pice of ****!Can't hold any power,even on street use with ceramic clutch i broke it after around 3000km!First it start make a serious noise and after that, you will need a trailing assistance!

[my2000apb]

so a standard torsen from o1e will go into rear diff?!?!

[diesel des]

Info please on the o1e to rear diff swap

[Biturbo]

Today dyno mapping and clutch spin but its small problem with clutch cylinder.
So it made 834hp on shell v-power with 2.3bar,we can’t push to max.

Beast! Time for some "better" fuel?

[K Simmonds]

That's pretty impressive, as above I'm surprised your not using 116 Ron race fuel.
