Pushing the limits of an I5...

[Michael Gough]

Hey there
Javad was running nearly 20 psi using the high compression MC block. The compression on it is 8.4:1 vs. 7.8:1 on the old MC. I don't know what kind of revs he was going to though. Talk to him about it, he sure has a lot of expirence. Re: revs, I think the redline on the NF/NF 2.3 naturally aspirated motors was 7k, seems to me that if you did the right work you could get the MC to rev to 7k easily.
