You're asking for trouble increasing the compression ratio on a C36. It's already high enough and the timing aggressive enough that this motor relies quite heavily on its knock sensors. When the underhood and therefore intake air temperature climbs on hot days, you will already get some ping on even the best fuel. The notion that AMG left some unlocked horsepower in this engine that's yours for a minimum amount of effort using old-time Chevy and Ford tricks is laughable. If you want a faster car, buy a faster car.

Excuse, pleeze
 

"Skimming" is self-explnatory, but what means "flowing."

flowing/porting ..ie improving the shpe of the intake/exhaust manifolds/combustion chamber... Epxensive time consuming work...and Very hard to find someone who can improve on an AMG head.

I'd still say a turbo pumping 5 or 6 lbs in would be the way to go. have a BIG water to air intercooler fabed up along w/ alcohol injecton and you should be good to go.

Although you'll prob. want to have your cam Cam Dr'ed to see if it is at All suitable for FI..if not you'll need to get a custom cam ground.
