Jeremy,

I dont doubt the power figure, as it does indeed tally with the injector flows that it us be seeing for the 1000cc injectors to be marginal. I was suggesting that even with a highly efficient turbo and intercooler, you wont see enough air flow for that power, at 2.5 bar, on a 2.0 or 2.2 engine, well, I dont think so.

One thing I didn't take into account is fuel octane. I know Simon uses race fuel from time to time, which is worth a fair bit of power, especially at that boost. Mainly from ignition advance, but all the same, it's still power.

SO maybe I was wrong, but I've been thinking in terms of regular pump fuel. Assuming he could add say 3 degrees of timing on race fuel (conservative), that could easily add another 30ft-lb of torque, and at 7800 (again, don't know the peak power speed), that equates to another 45hp. 4 degrees at 8000rpm it could be more like 55hp or so.

That said, BMW got 1400hp from 1500cc using 5 bar of boost, but on 116RON fuel and at 12000rpm (iirc). If that were equated to 2.5 bar boost, 2.2 engine and 8000rpm, you would be talking 800hp assume the same efficiencies for the turbo and intercooler.

So not outside the realms of possibilty, I just think there is more to the power figure than meets the eye.

If you see simon norris car behind you in the mirror you should be really scared when entering a hairpin.
