Hi AJM55 can I ask who was the competitor dyno shop you went to and showed you correct results. I know your first dealings were at RGM, I just dynoed my car stock and on paper she looks quite pap. Would like to get another dyno done before my mods arrive. Thanks bud.

Hi AJ, so from reading this thru again and my experience with this smaller supercharger pulley and belt wrap kit setup, did you basically gain 25RWHP going to mo's dyno. The 25hp gain was from the smaller supercharger pulley and 82mm tb. I had the smaller supercharger pulley and belt wrap kit done with a custom tune done on the same dyno before and after install and all I got was 15RWHP. I am showing 8psi (0.5bar) boost now which I think is right for the altitude we are suffering from. However I expected better results from the tune. Going to go for a split cooling system next to lower the IATS and see what happens.

From memory, a 25whp gain sounds about right. We lose about 3psi of boost up here so you'd be at about 11psi at the coast with your current set up. As Denroll says, if your IATs are out of whack, timing will be pulled. Our climate is severe and demands a more efficient cooling set up. Splitting the cooling and installing a trunk tank should help.
