ATP tuning for a different curve

Mangler · 06-11-2012, 08:55 PM

So will we be able to retune to change to a more traditional power curve? Just for conversation when would the turbos choke and fall off if it were tuned to reach max boost at max rpm.

I don't think that changing the power curve of the N54 is possible running stock or hybrid twins.Everything about the engine is designed for low-midrange torque. Even on methanol the stock turbos are probably not in good shape if you try to push 15psi at redline. And there's only so much you can do with timing at that point.

Just my opinion.

You can squeeze out high 15's low 16's with methanol. I would supplement it with race gas though for safety. I think some even run higher but your stock turbo's will be pushed to the limits for sure beyond 16+ at redline.
