I have an VR '05 8, with a OBX Cat Back Exhaust System, AEM CAI and a GReddy Turbo Kit... I put it on the dyno and the results were 272 HP???? is that right? shouldn't it be more? if anyone can help me i would appreciate it. ....

272 to the wheels is about above average for a greddy turbo owner provided that you're still using emanage. Hopefully you're not confusing the whp to flywheel hp.

Those are really awesome results. Most people with your setup will only make 230-240hp. How much boost were you running?

Yep. Depends on boost and tune. I turned the boost down to 6psi when I last dyno'd. It was 233HP peak at 11 AFR. pretty conservative. 272 to the wheels would be a great number if you haven't even tuned it yet.

How much boost are you running. I think I am going to find a dynojet to go to soon. I want to see those numbers vs. the mustang. Btw, whats up with the CAI with your turbo. Do tell kind sir.

ahahah woah no no i wasnt complaining, i was thinking that there was somethign wrong with it, that maybe it was wrong, but i'm happy with whatever i get, i'm new to the whole Rotary engine, so i dont know much about HP gains.... I wasn't expecting a lot from the GReddy Turbo Kit because i heard from people that it isn't the best one for the 8, but thats the only one i could afford :sadwavey: ...... yes i did have it tuned, but i didnt personally do it, i brought it to my friend and he did it for me because he had a 7 that was pretty modded. i was running 7 Psi during the dyno test, but it doesn't hold it for very long it definitely wasn't boosting at 7 Psi during the whole dyno run, thats why i was going to ask my friend to tune it again and make sure everything is right and then dyno it again. don't get me wrong i'll take any HP i can get.... thanks for all your help guys

What would it drop off to? I'm wondering if here are just variances in the turbo itself, because my stock boost is like 9psi, and I can hold about 8psi to redline.

Hey Moostafa, you're running the interceptor, right? Have you done a dyno yet?

Just to tune with. 230whp on a mustang. Tuning was pretty conservative, and that was done with a cooled off engine at 10psi. The final high boost tune was at 12.5psi, but there was too much heat soak to get decent numbers from that.
