Ran the car need help sorting torque converter,gear ratio & tire dia. Dynoed the car on Monday and took it to the track on Friday, [IMG]

At the track I rolled into the throttle and didn't hammer it until after the 1-2 shift somewhere on the top end it banged the limiter and I partially lifted.
3.50 gear, 26' tire 6600rpm rev limit
also on the datalog for the dyno run from 5400-6200rpm the mph stayed the same @ 128
Does the converter need to be reworked, or is it gearing/ tire dia?
1999 Firehawk
390, etp heads
83/92 turbo

Going by the RC engineering injector calculator I should be about 1000 crank hp.

did you stay in drive or go into OD? I have no idea if you guys go into OD on those or not.
I just punched your numbers into an online mph calculator and with 0% TC slip you would hit 146 @ 6600 in drive.
