Let me start off by saying holly crap is my exhaust loud. Personally I like it, but it is not for every one maybe no one but me. When you hit the gas it will make any one close by jump a good twelve inches honestly. Cruising and idle not bad at all,Then with windows up it seems like a normal car with exhaust. Under boost it is insane.
I have only drove the car two times today as they are still working to finish up. I went 185 top of forth gear with no rear diffuser or clam shell. It is a beast. First gear destroys my usually sticky Hoosier daily tires.
OK here is where it gets complicated. My shop uses a Mustang dyno.The dyno maxes out at 180mph. My car can exceed that speed in forth gear now.
So not only does the dyno give very low horse power numbers it also will not let me finish all the way through my power band. I will go to a Dyno Jet asap the same one I used when the car was stock. As for now here are the numbers.
Mustang dyno Before:469.7 RWHP 443.4 RWTQ
Mustang dyno After: 668.5 RWHP 612.8 RWTQ
Dyno Jet Before:571.82 RWHP 517.42 RWTQ SAE, Kenne Bell 91 octane tune
Dyno Jet After: ? I will get ASAP
It seems obvious I will have gained over 200RWHP on the Dyno Jet.
I am going to the track this Friday night that will be the true test.
So far my best is 11.42 @ 129.78
New Mods: Whipple w/23lb pulley only makes 21lb because of no back pressure.,109 octane fuel, Stainless Works no cats,Spec clutch,Twin Boost a Pumps,Accufab T-Body,CCW Wheels w/ M&H Race Master drag radials and skinnys in the front. Between the exhaust and the tire and wheel combo I lost over 100lbs.
