Title: How much boost on an NA?
Post by: hamradio on May 17, 2008, 09:23:22 pm

How much boost can I safely run on my NA?

Here's the setup-
Brand new headgasket, not metal
219k on the block
VNT-15
No oil cooler as of yet, but plan to add an air-oil one

Is 12 psi pushing it?  I'm not *that* concerned about longevity, if it lasts 20k miles I'm happy.
