I was reading an article on the PSP site concerning pulley's and was amazed to find out, that you have to remove the lower supercharger pulley to remove the rear serpetien belt?
I was thinking of installing there 2# lower pulley wich would solve this issue in the future,hope you don't need to change a belt on the road somewhere?

 

I went with the 2lb pulley just so I wouldn't be stranded if the belt ever failed. Cheap insurance in my opinion.

 

Can you run a 2# pulley without a chip?

 

I've got a 2lber and a 3lber(with tools and instructions)--and a chip that I'll make a deal for you............the 3 lber and chip dynoed at 388 rwhp and 467 rwtq--in July--in Thomasville, Ga--90*F.

Hey Dan,
I would enjoy the extra power, but I had rather wait on the chip for warranty reasons. Will the 2#er work without a chip?
I know these trucks run very rich anyway, so what will a little extra air hurt?

 

Just talked to a tuner--he said "no problem with a 2 lber, Magnaflow muffler, and no chip". Email or call me if you want to discuss this any further--just realized I should have mentioned this in 'classifieds'.

Yes you can run a 2# without a chip. Too hopefully keep this thread from being closed check the classifieds if any one is looking for one.

 

How much of a gain in power can one expect from only a 2# Pulley? How much of an ET reduction? I know it should help the bottom end some.
