Im using March P&A pulleys. Good quality. No direct before and after e.t.s because I changed other things at the same time. :chevy

TPIS pulley kit. Contains crank and Alt pulleys, no loss of charge at all for me with the diff. sized alt pulley. Engine pulled/revved a little faster after the pulley install. I've done most of my mods at the same time as another, but I did the pulleys by themselves, so what I felt was from the pulleys and not another mod. :seeya

March here too. Although I ordered the cheaper, black version. After several years I notice black starting to peel... big suprise to find polished alum under all that paint... Also installed w/ several mods so no direct comparison.

Re: whos using underdrive pulley kits? (jmrl98)
yeah,the kit stated what you'd need for it and you can refrense it if you'd rather have a different belt. i use goodyear gatorbacks since i work at a goodyear retail tire store.i put on the pullies today at lunch and can say i actually tell a difference :eek: probobly 10hp. now call me a lier but my crossfire responded well to the mod and i bet it picked up a tenth along with the fuel filter replacement too. when i install my LT1 pump in the tank later this week if i have time i'll gtec and post before and after both mods. :cool:

I have HyperTech pulley kit with the belt. I only used the crank pulley. So save some $$$ and buy only that. The kit makes the alt. go down too much at idle. If you only race COOL get the kit but IIKKWIKT I would only get the crank pulley....

Re: whos using underdrive pulley kits? (SHINOBI-X)
I got mine from racenet. Smaller crack, larger waterpump and alternator pulleys. No charging problems, no overheating problems. $129 and .2 less in the 1/4 mile. Used the original belt.
They are Auto Specialty pulleys.

Re: whos using underdrive pulley kits? (conv90)
it took me a whooping 20min to do it with air tools.hardest part was walking back to my tool box and getting the wrong sockets and extensions.not hard at all.
