what converter for turbo setup?
what converter for turbo setup? looking to get a converter to best work with my setup, best for the track not street.
the car is a 97 TransAm with-
383ci
76mm turbo
9" rear with 4.10 but my switch to 3.73
th400 trans. brake
car is 3500lbs
28-10.5 et drag
the trans. needs to come out anyway for a bad leak. I have a 3800 ptc and get 4600rpm on the brake, on the street it goes through the gears very fast and I dont think it would get to the 1000ft mark with any rpm left...

I'm running a Vigilante converter, very tight on the street, can cruise below 2000 rpms in 3rd.
I'd also go lower than you 3.73 gear if you plan on driving on the street. I swapped from 3.50's to 2.75's and my sixty foots actually improved. I was unable to hook on 3.50s

I agree on going lower with the gears too... more load = faster spool

no I have not dyno'd it, still have alot of thing to work out before that point, like pulling the trans. and getting my leak fixed, it is very bad!!!!
the car is more of a track car now but I do still have a/c and full interior, thats y this thing is 3500lbs.
In time I will build another long block and step up on the boost(only 10psi now), I'm looking for the 1000hp mark at the flywheel and would like the converter for that engine not the low hp. slug I have now...
on the spool part I go to 1/2 throttle and about 3500rpm and the w/g open, then on thr t-brake it gets full boost very quick.

4600 rpm on the transbrake is pretty good, actually. My last converter was flashing to 5400 and it still ran good numbers. I think your gear ratio is the problem, not the converter. Like others have said, the 3.73 will still be too much. I just switched from 2.73 to 3.00.
A couple of us out here run the ProYankExtreme 3400 & love it. (the other car has a 370 with a t-76 turbo) Very tight, runs cool, nice street manners, and yet flashes high & makes good power for the dyno / track.

I'd go less gear 3.73, I'm running a 3.50 in my 9".

3.5 gears in my 9" also and intend to run 28" tires!
