joe@cpr.com Posted October 20, 2016 Share Posted October 20, 2016 This manual C7Z came in for our stage 1 bolt on package. We did a baseline and it made 531 rwhp and 528 rwtq. Our stage 1 consist of the following. CPR 2.31 Upper pulley kit (no machining of snout required) Halltech CAI (this customer did the carbon one!!) 2'' Longtubes w/ or w/o cats. if w/ cats we do ARH longtubes, if offroad we do our own that we make. on 91 octane it made 604/608. Not bad for our lovely heat lol. https://www.youtube.com/watch?v=ykYFvvTJ18c Quote Link to comment Share on other sites More sharing options...
Guest badbobs95 Posted October 20, 2016 Share Posted October 20, 2016 I'm surprised that a stock Z would only net 531 HP. I know it's still a lot but I imagined it to be closer to 550. But then, I don't know nutton! Quote Link to comment Share on other sites More sharing options...

joe@cpr.com Posted October 20, 2016 Author Share Posted October 20, 2016 first pull it did make 552 rwhp and that's just normal heat soak from driving the car to the dyno. However the final numbers when tuning will typically be the 3rd or 4th pull so we wanted a true apples to apples so we did 3 pulls and that's how bad they heat soak. So the 604 rwhp number was actually the 4th pull btw. This car didn't do any of my cooling upgrades for the supercharger ie our ice box, heat exchanger, etc. Quote Link to comment Share on other sites More sharing options...
