Default Help me pick the better A/R

I'm getting a S-Trim T76 put on my STS kit soon. I'm running a built 346 (8.9:1) w/stg.2 6.0 heads and a small turbo cam. I don't run the car that much at the track but I do want a quick track car that will have decent spool time. I'm currently running the stock 60-1 (.96A/R) at 9lbs of boost and I'm making around 560whp 580TQ. I get full boost around 3500 rpm's. What A/R do you guys think will be the better choice if I want a quick track/street car. I know with the .96 A/R I'm going to have more top end but slower spool time, how much of a difference is it going to be with the two A/R choices and BTW I'm looking towards 800whp with my choice turbo.

Cheers,
John

Thanks Zombie. What RPM do you get full boost at with your 76?

I don't know, but it comes on pretty good. Makes full boost in 1st gear by 60mph on a low speed roll on. No real way to tell by RPM since i'm automatic, more boost = higher stall. Takes about 3 seconds to get 10psi on the transbrake though.
