Thanks Mitch..... I already posted in my build thread but I will put it here too.....

Remember this is a stock 90 GT longblock with a Carb and turbo..... I was shifting at 5400rpm(the rpm log showed it actually shifting between 5500 and 5600rpm which seem about right when you consider driver and trans reactions)..... The wastegat has a 9psi spring and my boost gauge was showing about 9.5psi.....

First pass leaving at 1700rpm off the old footbrake.....
60' 1.782
330' 4.802
1/8 7.340
mph 96.35

A/F was on the rich side but very steady..... It was basically 10.8 + or - .1 for the entire pass..... I jetted down 2 sizes in the secondaries and made another pass..... It was only loaded at 1500rpm this time so the sixty was a little slower.....

Second pass
60' 1.812
330' 4.823
1/8 7.358
mph 96.37

Not much different then the first, the a/f only went to 10.9 to 11.0 for the pass..... Not much leaner, I quess I have more work to do..... But it is definately showing potential.....
