Dynoed the challenger
 

2013 challenger srt8
Auto trans (5 speed)
K&N cold air kit <----only mod

424.10 rwhp
447.71 rwtq

Should be 20% drivetrain loss sooooo
508 flywheel hp
536 flywheel tq

They hit 165 mph on the dyno

I posted video on my fb page.....not sure how to post it here

Not bad huh?

I can dig it:)

Actually it would be 530hp at the crank if it is 20% loss but 20% is a little high these days. Probably closer to 16-17%. More like 511hp with 17% loss. Nice numbers nevertheless.

Very nice. So when does the gutting commence? :)

No gutting....it will stay full weight. :)
