Anyway, does anyone know theoretically what kind of HP difference there is between 10:1 compression vs 10.7:1 engine?
there was some post said 2.5%, but consider that evolve on 330 also give another 5+ hp gain, so if the 2.5 is true, and if the DISA controller is exactly the same (I read from somewhere that it was also tuned down to smooth out the curve), then the tuned N51 shall be same N52 high output. though all just in hypothesis.
