[QUOTE="cobrainfo1, post: 16834001, member: 204145"] And actually this is on the 3.875 pulley I do believe you could step down ONE pulley size to the 3.7 and still possibly be on 93 we were both in the same boat. (I will be looking to do so in the near future) I want the car maximized within reason on one pulley where I can still run pump gas. And have an E85 tune also for more fun. 900rwhp+ on 93 with this is absolutely nuts to me understanding boost - knock and everything else at hand. [/QUOTE]
