I just upgraded to GI joes 8 rib setup with a 3.2 RR pulley. Previously my setup was the 6 rib w/ 3.25 vortech pulley. I was getting pretty bad belt slip. Now there is none which is sweet. But for some reason i am down quite a bit of power and was wondering if summertime temps/humidity can affect the numbers this much:
6 rib 3.25 vortech pulley @9psi= 400rwhp/403rwtq (dyno'd in march when temps were prolly in the 60-70's here in TX)
8 rib 3.2 RR pulley@9psi= 377rwhp/375rwtq (dyno'd yesterday temp in the high 90's & about 80% humidity)
What do you think, is this normal summertime power loss? or should i look into something with the car?
