I re-dynoed the truck today as it would go fat on the top from 6,400-7,400. Since I found it liked to be twisted to 7,400 when I was at the track, I decided to re-dyno it and lean it some as it was going to 10.7 AF.. Only other change is I put a ASP UD pulley on it. Here is the full scoop.

Stock Block Cleaned up
Stock Crank polished
3.905 Diamond -2cc piston
Eagle rods
.045 gasket
TEA heads
Trex
Stock lifters
Sock rockers
No MAF
LS6 intake
Ported stock TB
ASP pulley
Stock Water pump
Edelbrock 1 3/4 stepped 1 7/8 HVMC headers
3" X-pipe
Warlock mufflers corked

Stock 4L80E
3,200 Fuddle verter
12bolt
3.73's
275/50/15 BFG DR on steel 8" wheels


Over lay is old tune and stock pulley vs now






It went 12.33 @ 110mph weighing 3,840 with me with the old tune/pulley. I wonder what it would pick up with a Fast 90/90 and an EWP. Also wonder if I can get in the 11's now after a gear tire change..

Very good numbers. Looks like the torque converter was locked.

You should get a tq converter that stalls near your tq peak, then you will have your 11 second pass. Good numbers though.

19rwhp and a decent rwtq pikcup for just a different tune and UD pulley sounds great to me.

The first pull of the day was straight off the street and hot and it was like 405rwhp. The old dyno was 409rwhp at 180* temp so I can't tell you what the pulley itself did.


Reason I am not going with a bigger verter is I still have to hit the N20. Not sure what that is going to do to the flash speed of the verter. If I can go up at that point, I will.
