SCOBRAC , 750HP Hi Guys. The new learning curve is changing. There are guys racing with 10:1 motors and 10-15 lbs boost with no problems. Instead on having a fast boost build up in the lower RPMs, they slowed it down and are going to a higher rpm for the same power. A kid living behind me has a camero 2001 with the LS1 and a 6 psi kit. It is intercooled. It took 2 days to install, but it runs on 92 gas with no problems. Has car does the same thing with the boost starting at 2700rpm up to 5700rpm. The weak valve springs stop the motor from higher revs. He is putting new ones in in 2 weeks. and got a smaller pulley. There is less stress on the motor and detonation at 6000 than at 3000 rpms. The car chassic has to handle the power increase without getting unstable. If you drag race, and the motor comes on boost quick, the tires just get blown away. You also don't need a big cam to make big power, 230degree at .50 and 500 lift will get you 1000 hp at 7500 rpm with a good system. my 2 cents Rick Lake
