[QUOTE="biminiLX, post: 15609284, member: 7795"] I was happy with my IW 15% lower/stock upper and 93 pump with some Torco when racing. Even without Torco the Lund 93 tune was safe on datalogs. The lower pulley gives you a better SFI balancer and better belt wrap. I think you'll be happy with the 10%/2.5 . Jam you seemed to enjoy the drag style like I do, so upgrading to a rear ice tank and HE with fans might be a good idea. Consistent low IATS allows higher boost on pump. I actually just finished replacing my front bumper with a tubular design, allowing me to add fans to the stock HE and finishing the rear ice tank lines. Cars ready to rock, going up in 2-3 weekends for some fine tuning and just enjoying the car until fall racing. -J [/QUOTE]
