Here is what I'm looking to do...

AEM Brute Force Intake (already installed)
4lb Lower Pulley
C&L Upper Plenum
Custom Predator tune by Danny Swanson

Tthinking about an Accufab - more for the throttle response.
Installed a FTVB today.

Do I need a new set of plugs with the set up? Or will a good tune take care of it. Also, what about going up to a 6lb pulley. What is the difference in HP/TQ over the 4 lber.


Am I looking at around 380 hp to the rear wheels? How much torqe?


Thanks In Advance,
Jeff

 

You should be able to make the hp you are guessing pretty easy. An up graded set of plugs like NGK TR-6's will work better for you.

As far as the accufab SBTB I could think of many better ways to spend 300 buck. The gains are small with your mods using that SBTB.
A good tuner will bring your set up to life!

you'll be in the 400/500 club or VERY close to it.

 

Thanks for the input guys...

This is probably a stupid question but how would you figure out the horsepower at the crank. Lets say if you are making 400 at the wheels?

I am not sure what the exact % of loss is on our lightnings, however I have always used 20 % for drivetrain loss with an automatic transmission..


only way to truly get that info is to jerk the motor and throw it on a dyno..
