76mm .96 ar turbo 400 TRANS with 2800 ballooning convertor . Just swapping from nitrous to turbo as we speak ? My real question is my gears for now are 411 in a 9" with fool spool and moser 31 spline axles , caltracks and

Enter your info and check. Unless your running baby boost and/or really heavy, I'd guess no.
Don't forget to factor in slippage from the converter too.

Turbos LOVE high gearing. Blower and nitrous guys when making the transition always make the mistake of running too much gear. Even if it's a track only vehicle least put some 3.55s in it. When you finally do you'll be asking why you didn't do it sooner.

Verdad Gallardo I'm listening Most can't shove a 30"+ tire in the wheel well. If you can, go for it. Should get you in the 130+ trap range with a slippy converter and 30" tires. If your running 10lbs or less I doubt you'll be trapping much higher anyway.
315/60/15 Really depends what kind of power your making and how bad your converter slips.

It's too low of gear IMO unless racing 1/8 mile with a 2nd gear start, or 1.58 first gear glide maybe. About a 3.55 is as low as I would go for a 1/4 mile car under 4k LBS.

3.42 or 3.55 is a great gear for the turbo
my ttix turbo vette *800 rwhp* went from 10.5 to 9.8 going from a 3.90 gear and stick to
3.42 gear and auto
granted, much of that was the better launch from the auto, but clearly loading the turbos has gotten them to spool quicker and get into the meat of the torq curve earlier with the taller gears
kinda opposite of a N/A car but turbos love the load
engine will last much longer too not zinging it up but rather "grunting it" a bit

15 years ago I ran a buick gn with a 100 octaine tune it ran 11.40s with the 3.42 gears for 2 years. I picked up a 9" axle for it and it had a 4.00 gear I thought it whould fly . it ran 11.80s . I tried to make it work but it just didn't like it . I had a stock 3.00 gear laying around and just for the street I decided to swap it in and I could not believe how good it felt so I took it to the track . ran a best of 11.08 whould run 11.20 every pass .
as a side note the best 60' it ever ran was with the 3.00 gear. 1.48 @3700#
