Last year I made a couple of passes at over 40psi with a PTE 88

A friend with fully ported GN-1s and a stealth turbo - a 70mm wheel in a stock housing I think - is all done at 26# at 5800' elevation it just wont build more boost.

Cal- WOW, what head gaskets did you have on the block to get that 40psi and keep everything together? I take it was on a stage block right?

1007 gaskets.

I don't normally run that much boost. I just was just trying to go faster
