What size turbo are you using, and what is your Turbine A/R?

Only a few GN owners here. Might want to check out http://www.turbobuick.com/forums/ if you haven't been there yet.

Had a TA-49 for the last few years but sold it a few months ago. That thing would SCREAM over 20psi and spooled about like the stock turbo. A buddy of mine is running a TA-62 on his 86 and it isn't near as loud... but makes a little more power. Just a little :) (mid 10s)

I'm running a T70 with a .85 A/R. Works very well...

My GN had a PTE-52 turbo which had a 60mm inducer and A/R of .63 on exhaust. It ran 11.1@121mph @21psi.
