How much boost?
I want to put a procharger on my motor but it is 11.7 compression. Anyone have any opinons of doing this? My buddys M3 is 11.6 com. and he has 7 lbs on his and runs great on pump gas(i know its not an ls2)but what do you guys think. I put down 475 hp and 575 tq the other day on the dyno also just alittle more info. All parts needed to know about are in my sig.
Thanks in advance

well that huge *** cam will bleed off some of the compression. Can I ask why you are running that cam? Were you planning on going a different route and now you want to put f/i on? You may not be able to run as much timing as you should with that setup.
If I were you, I'd change the compression and get a milder cam you don't need that.
If you decide to keep it, run some good gas, even though your car is light and the load won't be as much that is not boost friendly compression.
If it were me I'd change your compression and cam, you simply don't need that for forced induction.

I WASNT PLANNING ON BOOSTING THIS MOTOR BUT IT DOESN'T SOUND LIKE A BAD IDEA AND IT IS A TORQUE MONSTER THE WAY IT IS BUILT AND I LOVE THE CAM. WHY ARE THESE BMWS ABLE TO RUN UPWARDS OF 10 LBS OF BOOST WITH 11.6 COMPRESSION? AND ASSUMING THAT f/i MEANS FUEL INJECTION, NO I DONT WANT TO PUT IT ON THERE I STILL AM GOIN TO RUN THE CARB SETUP. RIGHT NOW I AM RUNNING 29 DEGREES OF TIMING WITH 93 OCTANE ON THE STREET. I DRIVE IT EVERYDAY GETTING AROUND 15-16 MPG.

This is a pretty simple way of looking at it, but the same principle applies to any engine really.
