First Dyno! Did my first dyno today.
Stock '02 Firehawk with 345hp Alteration, only mod is a cutout.
With Cutout Open:
325.5rwhp / 338.3rwtq
With Cutout Closed:
320.8rwhp / 338.5rwtq
So I got 5rwhp with the cutout open. I was pretty pleased! With 12% drivetrain losses, that puts me at 370hp at the crank!
There was an '03 Cobra there that did 442rwhp with just a catback and intake. Cool guy and he was SUPER happy with the results.
A pretty tricked out Supra pulled 452rwhp. Pretty sweet for a sixer!

Yeah, I really like the cutout. It is a little loud with the windows up, and drones at 2k rpm, but I am going to try and fix that with a turn down. Overall, it is great! I love it!

Looking at the torque data from 3k to 5.5k, the cutout open was 1 or 2 ft-lbs higher than with it closed. For the most part the torque was almost exactly the same open and closed.
On a different pull when my peak hp was a little lower, my torque was 0.5 ft-lbs higher with it open then the closed pull. Now below 3k, I have no idea, but above 3k, it is almost exactly the same.
