Just got my car back after having my stock heads and Typhoon intake ported. Got good news and bad news. The car gained so much power that it is making the trans slip in 4th gear when at read line. The entire Dyno graph looks like a 6 speed with a slipping clutch. Mine has a drop off at around 6200 RPMS than catches up and starts building power again at 6700 RPMs. As far as HP and torque goes it looks like I picked up another 40 corrected RWHP on their Mustang Dyno. On the street there is no sign of slippage anywhere either by tack or seat of the pants. We might put the car back on the dyno next month just to check it again.

 

HP befor and after?
