How many of you guys have the 8.1 and what have you done to it?

I have see some cold air kits, a few camshafts, different valvetrain parts,
headers, exhaust. A whipple is a bit pricey for the amount of power you get out of it.

Also does anyone have any stock dyno numbers to compare?

Thanks.

 

Come on guys, wheres the love?

all I hear is lots of crickets.

 

we got a cam valve springs cold air ported throttle body good wires headers, and a full 3" exaust with a X pipe and the bottle and it made 505hp and 619tq... it went 13.58 @100 before cam and valve springs and new exaust and runs alot stronger now
later
