Whatever boost that ends up may be more on a stock motor because it is more restricted.

700 may be good if your lucky but who wants to be lucky? I was at 658rwhp on a liberal dyno and it blew within 500 miles and on the 6th 1/4 mile pass. I wasn't lucky. If I was to do it over I would forge before getting over 8-10 psi. Hopefully my car just had weak internals?
