Psi is all relative to if the heads are stock, mild ported, or all out ported to the max ect ect... A 35r car with stock heads might make the same power at 30 psi as a 35r car with ported heads at 24 psi... n2oiroc I can't wait to see your results get is done asap lol! Btw I make 200 wtq @ 3250rpm airboy w/hta86 stock block(hybrid 2.5l) and 518whp 404wtq at just 25psi stock heads no porting...So that Sierra evo spool-up isn't all that impressive to me really...
