If the dyno is a bit stingy, I'm going to say 560/525.

Don't know the details of the car or the dyno. Assuming dynojet and C5Z?

If so I'd guess 565/530. Have to go back and read the engine numbers I forgot the tq haha.

That's about a 15% loss. Pretty cool. What all is added to the car that wasn't added on the engine dyno such as water pump, altenator, etc?

Hey Kevin, didn't I guess 567 rwhp 520 rwtq ? Because of the nickname of that dyno they use, "The Heartbreaker". Ed has posted 560/510, looks like I was close. Lets see if he can't work his magic via tuning and get her to make a little more. Just so I can be right

Who cares about Peak hp/tq, your car flat out makes power everywhere. Can't wait to see the graph. I'll bet she does a stump pulling 450 rwtq @ 3000 rpms or so !!!


SHAWN, are you "hotlapping" her on the dyno, or allowing X amount of mins to cool down so that each pull starts from the same temp?

400 ft pounds from 2300 up. She's a beast.

Gotta slow down the big throttle body. You crack it a little, and she wants to go! Idle and return to idle is damn near mint! A few small adjustments and it'll be like stock.

Drum roll please!!!!!!!!!!!!!!!

Cutout's open, no air filter. Basically, the way it was run on the engine dyno.

4 or 5 pulls, and it made this with ease.

Edit: Run 12 was the best on the old motor.

The A/F was actually flatter with the cutouts closed.
