377RWHP Mustang Dyno - Low Numbers? Video inside
« on: April 06, 2021, 07:57:58 PM »
Hey guys recently had my car tuned and dyno’d by the same guy and made 377rwhp and 367 torq.

The car is an LS2 with BTR Stage 2 Cam with springs/retainers (Can provide specs) , ATI Damper, 42lbs Bosch Injectors, A/C and P/S. Has your typical ram air setup.

Compared to other cars and corvettes and their “cam only” numbers, I feel like this number is considerably low. Any thoughts?

Mustang dynos are notorious for reading way lower than any other dyno, can be something like 15% plus depending on settings. I'd wager you're somewhere in the 440s on a Dynojet, which is usually the preferred figure for keyboard racing.

The shape of the curve looks similar to other dyno sheets I found online of that cam. I'd also chock it up to Mustang numbers.
BTR's product description for that cam says "It is common to see over 400 whp with this grind", which I'd wager you are in that range on a Dynojet.
I'd be more concerned if the curve looked funny of fell off earlier than usual.
Enjoy that super flat midrange!

The dyno jet is 12.5% more than mustang dyno putting it at 410 I believe
