The rule of thumb I have always been told is that for every point in compression you go up, that is worth 4% in torque. and you can go up damn near a solid point, as the stock ls3 has a 10.5 c/r. So you are looking at 20+hp in just milling alone.... let alone port work and blah blha blhablahblahblahblbhalbhalbhablhalbhalbhablhablhba insert ricer internet racer math here balhblahblbhalbhalbhalbhalhbl

yeah that 4% is commonly thrown around because people used to bump their compression from 8:1 up to 9:1 back when combustion chambers were crappy designs so engines had low compression from the factory. Bumping up 1 point of compression from 10.5 to 11.5 is not going to gain nearly as much as bumping compression from 8:1 to 9:1. a 2% gain can still be worth it though, even if it is 100bucks. sheesh.

that might be true. But out of 5 people ive seen post on this site that are cammed only 3 are on the list. But out of those 5, ive seen 116mph , 115.5mph, 115.5mph, 118mph and 121mph....the 121mph run seems to stand out more than the others. thats all im really saying.
