cam for a turbo?
#2
I say cam it like you want it to drive - There are "ideal" cams, but the turbo will make power either way.
Look up Speed Inc's car when they had the lt1. He did a lot of cam swapping and found that every time he went to a bigger cam (even ones with more overlap that suggested for boost) he made more power - Just at a higher rpm range. Well guess what an NA car does with a bigger cam.
If you want to spin it to 7k, get a cam that will do that. I have a 218/224 112lsa cam - technically I still have a little bit of negative overlap, but between the baby cam and tiny turbo I only spin it to 5500-5700ish at most.

Yeah, it seems like it was so long ago! That was back in 2003... and a few months later I tore it down for the big build. Never got a chance to get it back together.
The tq was great... those numbers were with LE stage 2 heads from 2003.

It had a good lope to it (probably a 5 on a scale of 1-10). Powerband was perfect IMO. It would buck below 1500rpm until I got the tune worked out, then it pulled pretty smooth down low.
