i apologize, i missed the 20" DR's. I thought they looked smaller in the video. obviously its all relative... a 5th gen on 20's isn't going to lay down impressive ET vs rwhp. its just comical to see people j i z z over something that is nothing more than expected. anyone that spends 1500 on a cat-back or headers is a freaking moron. You can get a set of mufflers for $100 and have them welded in/installed and get the same or better sound/hp for 1/10th the price. you could also probalby go to home depot and make a CAI for $50. the aftermarket companies are going to rape people until there is a decent supply of aftermarket parts for the 5th gen.

To be losing 20+% at the wheels, you must be running a 9" rear end + an inefficient transmission, such as a C6 or maybe even a TH400. |

We have done a large amount of testing as well as baseline runs on SAE Certed motors . Also back to my first post The 6l80e takes more power to turn like a 4l80e so less then a 4l60e |

John at Hennessey,
I have a question about the HP gains. You show that you had a 14 hp gain with the CAI. What was the gain with the Corsa exhaust and did you try any others or is that the only brand you use? |

as an example, here is a superflow dyno of an 03 Cobra motor with a pulley only (basically, my set up) thats 583 HP and 574 TQ. And that equals out ~450-460 rwhp. BS. That would mean a GT500, that makes 500 SAE certified hp and makes ~440 rwhp, really makes 550+ HP? I don't think so, otherwise there wouldn't be an SAE Certification program. Same goes with the LS3, LS9, LSeverything. EVERY engine that has been certified. I will agree with you that an engine loses 20-20+% when going from a superflow dyno to chassis dyno, but a superflow dyno is not what is used to rate HP in the SAE Certification program and also is not the dyno used to calculate factory engine HP's. |

At this time, we have not had a chance to test Corsa or any other exhaust systems on a Camaro without the blower. Hopefully we will soon.

As for the superflow engine dyno they do have an SAE setting and we request it is used and our results seem to be within 1-2% .. Also keep in mind a 3000lb roller can't create an equal a load esp on a 4000lb car . |

dude, how are you going to compare a 4th gen to a 5th gen when the previous generation is like 450-500 lbs lighter.
