I just came from a dyno session at HiTech Motorsport. They installed their new Predator H/C/FAST high velocity combo on my car. (228/232 585/585 114/velocity ported 5.3 heads/ velocity ported 90 mm FAST intake manifold) We are very pleased with the results considering my bottom end is stock
Here are the last three pulls (SAE corrected):
461.28/426.21
462.78/428.95
460.49/430.81
Here are the last three pulls (STD corrected):
471.98/436.09
473.33/438.73
471.15/440.78

So here are my ?s.
How much RWHP gain do you really get from a pulley? (I would like to have a 550 FWHP car)
Can I spray a 100 shot or a 150 shot with this much power on a stock bottom? I do have a Racetronix Fuel Pump Kit going in but I don’t know how much power I can put through a stock internal LS1???
