I have a 1/2 chassis, full race, 347 stroker from Bennet Racing, Trick flow Twisted wedge ported heads, old S- Trim Vortech supecharger, 1 7/8 Kooks Headers, 80 mm MAF Cal. @ 50, 50 lb injectors. I fill the car is lacking top end. best run 10.3 @ 127 mph. 1.35 on 60 feet. Stock computer with rpm and other sensors delete.Could it be the old Super Charger is "tired"

 

On an engine like that, you're lacking a tune, and cam selection plays a large role in powerband.

 

True! My Cam;: 580/580 lift, 286/300 duration. Any suggestions for the tuning, Programmable Computer, etc.? Thanks!

 

not enough info to make any type of assesment.......intake?? head size?? 170's, 185's?? ect ect, stock block?? how many psi??, catch the drift??

 

Heads 185 ported, stock block, 8-10 PSI ,

 

Holey Systemax Intake.

 

I wouldn't push the stock block any further, your not doing bad considering what you have to work with, is it intercooled???

 

Wow low 10s on the stock block. Do you have many passes on this set-up?

 

About 5 pases total. I had this engine and trany ( C 4 ) on a full body, best pass: 10.28 @ 132 MPH, 1.31 on 60 feet. Now the set up is on a half chasis, about 500 lb less, I think something was lost when I swapped bodies. Now I have 14 in Tires, 9 in rear.
I don't have an intercooler. The only think that I've added was a Computer chip to delete RPM limmiter on the a stock Computer, it was cutting off @ 6400.
