76 turbo 55#s on 3.8

[cutt]

any opinions on this combo

Way to much turbo and not enough injector for the turbo.Requires 4000 stall convertor.

bigger injectors

Cutt,
You need to go back to the drawing board - only two things will happen with this combo: 1. Bad Things 2. Not good things

I would go with less turbo TE45A / TE63 these turbos make sense with 55lbs. However, if your are thinking big turbos - bigger injectorts - 72/83 - will be required.

76 turbo

car already runs 10.47@126 trying to pick it up to about 130.it had 50#s in it at the time.stepped up the injectors,but slowed i'm going to keep the inj. step up the turbo from a 63 4 bolt to ? any suggestions block has been cryo treated with steel main caps and a stud kit ,no girdle.9 inch coverter

 

[TURBO 6]

Cutt, the radiator you sold me works great. Coolant temps don't go over 160 in the heat.
If you go with a 76 go with 83's. I am damn near out of fuel with my combo. (45a,55's) Later.

I'm running that turbo, a 4 bolt housing and at 25psi it'll only do about 126mph, but when it hits 28 psi the motor starts making power.

I've hit 130.8 on 29psi and had a terrible breakup when I ran 30 psi, but still hit 129.8mph.

I'm running 95lb injectors and at 54% DC.

sounds right my 50's were done at 127 mph...stepping up to 75's

i have a lt70-1 turbo and i like it the 127 pass was 23-24# boost and im on stock valve barely ported heads

im looking to go back to track friday after next in search of 130+ mph.....good luck
