Lower pulley users??? 5# 4# 3# 2# what are you running & what do you like the best?

permalink · 11-28-2001, 08:13 PM

I have a 3# lower on the truck to play with, originally was going with a 4# (still might) but was given the pulley to try. I like the increase in low boost performance and gas mileage has stayed the same (15-16mpg). Anyone try the 5lb? I really don't want to run an upper pulley so adding one isn't an option for me. Any thoughts? Concerns? Consideration?

Thanks,

I would just go with JL's 5 or 6lb pulley. Get the chip programmed for it and you will be fine. Either pulley and you will lose mpg if you're in the boost.

I have JL's 4# pulley and I'm very pleased with the results. If I could do it again I would probably go for the 5# or maybe even the 6# pulley.

Anyone have horsepower per pound of boost info? Or how many horses can I expect from 4# pulley?
Most supercharger manufacturers claim 40-55% increase in HP. Most use 6-8psi.(I think). So
Lets say 100HP gain, if we add 50% more boost (4# pulley) it would seem we could expect 50% more HP or 50 HP gain. What I have read in the posts is far less, could you explain?

Has anyone tried lower pulley upgrades after the intercooler recall was done on their trucks? Did everything work fine? If you had a chip, did you need a reburn? For those running 4# and higher boost, have you experienced any problems after extended use under high boost? Any overheating, engine damage?

I have the #2 lower and the 1.5 Metco interchangeable upper and I ran a best of 12.92!!!

I might have broke in the mid-12s, but I am having bad torque converter problems right now and that was the best I could muster!!

For me the #5 and #6 are WAYYYY to much for me, but to each his own!!!

Personally I wouldn't go any higher than 3 psi. Its more than enough for a street truck IMO. With the mods I have in the sig plus Bassani crossover pipes, there is no hook to this truck below 3 gear. Its great.

I went from stock to 2lb--then to 3lb--as I'm installin it, JL announces a 4LB! May go higher but as to heat or problems--none! 16,000 miles--drive it daily to work--and-see sig.
