BTW Andrew why did you guys stop using Rotrex in your kits and switch to HKS? Did you find that the HKS performed better at lower boost?
Roman, I made 645WHP SAE, at ~11psi. The AA development Stage 3 car made 560whp at ~10-11psi, so that's quite a difference ~85whp at roughly the same psi, both cars with lowered compression. I'm wondering why a few people in some circles claim the Vortech #'s are underwhelming, but yet had no comments on the Rotrex results.
