Which Pulley? I have an 01 Trans Am M6, looking for a pulley. Should I go with March, ASP, or SLP. I'm leaning towards the March. Also do i need both pulleys? I would rather skip the alt if that is ok.
Either go with the ASP or March pulley. The ASP pulley is SFI certified and has been around for a couple of years with proven results.
You dont need the alt pulley, but you won't be getting the full gain of HP by skipping it. With the M6, you would not have any charging issues unless you have a HUGE system in your car that drains a lot of power.
We are also have a sale on the ASP pulleys right now

so I need both for full hp gains? I thought most were getting 8-10 by using the crank only, maybe I'm wrong. I don't have a huge stereo so charging isn't a biggie, i just want more power and know this is a proven mod

damn pulleys are confusing lol

And I still would like to know if both ASP and March Pulleys work with the Rollmaster Double Roller timing chain and ported ls6 oil pump. From what I have read by searching, the newer ASP seems to work but March is up in the air. It has worked for some, but no sponsor or anyone has said it will work. Also, when you don't consider the fluid in the march as rotating mass, which weighs more? Which has deeper grooves so the belts won't slip? Do they both underdrive the same amount? These are the things I want to know.
