Guess the question is what do you want to do with 650rwhp? I'm at 645rwhp on a Mustang Dyno - so, around 700rwhp on Dyno Jet....you can see what I run in my signature with that.....Plus..MD03SVT has ran alot quicker with less:
07 Shelby GT500 coupe 10.47 @ 131mph Stock un-ported Blower w/2.6 - napierville dragway
10.37 @ 130mph TVS w/stock 3'' pulley E-Town
9.87 @ 140mph TVS w/2.60 pulley napierville dragway
If you want more than that then get a KB 3.6LC, 4.0 whipple or NOS....:rockon:
Only thing I'm gonna do is drive it around Maybe hit ATCO I'm not putting a cage in though so faster then 11.5 and they throw you out. I have a Z06 with 600rwhp and at only 3100lbs that car can be a handful. I just wanted a good safe way to make the power and figure with the added 1000lbs of the GT500 650 rwhp would be nice.
