[Juiced G20]

Im going to purchase some Unorthadox pullys for my 93 P10 and i was woundering what kind of gains i can expect. Does anyone have them on their car? If so did you notice a difference? Which pullys came in the set? thanks all

I can't remember how much hp they give. I think it was about 6 hp. Actually, pulleys don't add hp, but they allow the engine to rev quicker and that shows up as hp on a dynojet. On a brake dyno it wouldn't show up.

I installed my pulleys with my first gen Stillen header and it was very noticeable. I think pulleys are a great mod because they improve acceleration with no downsides. In fact, they also correct a problem with the waterpump at high rpm. At high rpm the SR20 waterpump cavitates and that will cause overheating on the track. By underdriving the waterpump, it actually is less likely to overheat.

They took me an hour to install on my P10. If you've never done it before though and don't have an impact wrench for the main pulley bolt, it could take 2-3 hours.
