[Mk2] [Turbo] Adding a supercharger to an existing turbocharged 3S-GTE

Cheers Mike N, Peter from sbits very kindly pm'ed me some dial in sheets a couple of nights back.

The car is used for sprints and I can only get 265 tyres on the rear. It will have anything from 650 to 1200 HP, and the max revs will be around 9000.
The main problem with any two wheel drive car is getting the power to the ground so by bringing in the boost later I hope to stop a lot of the wheel spin.

I can't see how having the same torque in at higher rpm will be any less likely to spin it, you've still got the same tractive effort at the wheels surely? Then again, I know nothing about sprints.

1200 HP from a 2 litre? That's going some, even at 9000rpm ... or have you got something much bigger in there? Curious to know how much boost you're going to need for that.

Cheers,
Kingsley.

The wheel are already turning once you're at 3.5k rpm, so less likely to spin than when ramming home loads of torque from a standstill I guess.

1200 horses from 2.2 litres...a fekin huge turbo, lots of revs and race fuel

Lots of boost too I would expect!

Is it even possible to get much boost below 3500rpm on a 2.2 litre engine from a turbo big enough to make 1200bhp? I wouldn't have thought that low rpm wheelspin would be much of an issue on such a setup.

Cheers,
Kingsley.

Yeah- I think we're all keen to see how Bob's build turns out, I'm guessing there's going to be a lot of post cylinder fueling going on in there...probably race fuel and NOS as well
