Hi,
So I'm about to have the following setup (all already installed except the driveshaft) on my 2007 Gt automatic:

C&L Racer CAI with 93 Tune from Brenspeed
Steeda Underdrive Pulleys
Shaftmasters 3.5" one-piece aluminum driveshaft
Flowmasters AT axleback exhaust

..so, anybody out here with the same (or nearly so) setup that has done a dyno run? I'm curious where this puts me, for HP and RWHP compared to stock. Should be about 330HP, I think. Not sure about RWHP though.

 

Flywheel HP would probably be higher than 330hp. The CAI and tune alone are probably good for at least 25hp. Ide say your probably 340-345 at the flywheel, and maybe 290-295 at the wheels. Thats just an estimate, bring it to a dyno if you want real numbers.

 

probably close to 300 RWHP and in the 340's at the motor

 

Not liking the flows? Without the pulleys and the driveshaft and the tune, I was running 281 RWHP... granted it was a K&N but I'd imagine you're somewhere in the realm of just over 300 rwhp and 340ish at the fly.

 

The flowmasters are ok if you want to get louder but still keep things civilized. Better than stock. But not as nice-sounding as the Stingers!

 

whats at GT/CS auto bone stock #'s look like on the dyno?

 

Coming from an auto guy...you will be starting around 260/260. We give up at least 20/20 to the manual guys.
