S54 pump and boost
Okay, so it's no question that cars always perform better on better quality fuel I.e. Meth, c 16,ect.. When they can take advantage of it, and I see how well the s54 does with race gas and methanol, and I just wonder if some of those same numbers of whp can be obtained through straight pump 93 octane I.e. 700 whp on pump, I can understand a number of reasons why like BMPE pressures, piston speed, unadjustable tune option like knock sensor, or even just for safty of the motor, just a little thought I have that I hope some one can shine some light on.

I can definitely put out 700whp on pump gas if i want to, normally though im closer to 650-680whp on 91oct. You're going to need roughly about 20psi.

Honestly, you are going to need a built motor and then some for 700 whp on pump.
You are realistically shooting for the mid 500's on pump.Stage 2 or 2.5 E9X M3 S65 V8 supercharger kit for sale: http://www.boostaddict.com/showthrea...r-kit-for-sale

Yes, this definitely requires a built motor, a solid fueling system and very good tuning.

cool, I definatly know it requires a very good tune and built motor, I just havent heard of someone doing that honestly, just wondering if it could be done on this particular motor, without drastic changes
