Does anyone have any dyno numbers on the 4# pulley vs. the 6# pulley? I'm stock and will be getting a chip and pulley, just trying to decide why or why not to go with the 6#. I've heard the 6# may be more boost that what the supercharger can really flow?.?.?
So, any dyno comparisons?

Thanks!

 

2001 Lightning,

Shoot me an e-mail!

 

High Roller, i sent an email earlier, no reply. Anyone else? I would think someone has dyno numbers comparing the 4# and 6# pulley?

 

Guess nobody knows

 

2001 Lightning, I don't have any Dyno numbers to compare but I have a 2001 with a chip, 6# pulley and shift kit. My best friend has a 2001 with a chip, 4# pulley and shift kit. We installed all our parts together and run at the same track on F1's with 28 psi. My times thru the 1/8 mile are 2.5 tenths quicker than his. Maybe this will help. It all depends on how fast you want to go. His truck has been dynoed with the 4# and all it had 404HP and 516 # of torque. I don't know about mine.

 

Those numbers are not to shabby coming out of the rear wheels on a daily street driven vehicle.
