Hi!

What's the new compression on the NA mkiv with a 2mm HG, and how much boost can I run (98 octane)? Ca. rwhp on this boost?

I'm pretty blanc, so please help me!

Thanks

Not sure on the 2.0MM as we only use 2.5MM on N/A-T. The 2.5MM creates an 8.8:1 compression ratio which is right where you want to be. As far as how much boost, we generally only run 12psi if all we do is put the kit on, tune, and the customer doesn't want to pay for us to inspect the longblock. With a good longblock I don't see why 15-16 PSI should be a problem.
