Awesome, now I just have to wait for you to uprade your exhaust and dyno again :)

I'd like to see that too. I've had some discussions about the negetive effects of backpressure and I would love to remeasure the backpressure on your Vette after the upgrades and then see what the difference is on the dyno.

If I may hypothesize here, the torque curve will simply shift to the right on the dyno graph with only an exhaust size upgrade with no tune or cam replacement in mind.
edit: wait wait....if I have this right in my head, increasing the exhaust size too much would cause the curve to move to the right (RPM range). Why? Well I figure too large of an exhaust would take a higher amount of exhaust pressure to create velocity, in other words higher RPM's needed. Too small an exhaust we have a restriction of the velocity trying to release. |

Hmmmm I have my head rapped around this now. Need to find something else to occupy my time haha. We'll leave it up to the dyno :)
edit: YA! Without using any formulas and just winging it, anywhere between 2.5" and 2.75" should yield a better power curve. ^^^^This guys is right!! As I said though I think too large and the gains will only show on the top end. I don't know why I'm bringing all this up, it just snapped into my head this whole exhaust theory ordeal I heard about. |
You do realize that your car is already really fast don't you?
