your stock power to the engine is [email protected] RPM. torque is 335ftlb @ 4000 RPM
. probably take 15-20% off to get rear wheel power.
I have the same setup you have but in an ext cab. the dyno sheets from their websites state:
K&N: +11.92hp @5367RPM
Hypertech: 87 octane=250hpmax to rear wheels @ 5250RPM, 279lbft of torque max @ 3750RPM.
flowmaster maybe mutiply your base hp and torque by 5%.
i doubt you could beat a hemi but maybe. i still get smoked by Nissan Titans. but the 3.e42 gears dont help towing or draging.
what gears do you have?
i would love to know the results of your dyno run when you get it done.
