Just bought a 2007 roush 500RC. I have a pulley kit and a larger induction hat, and a custom tune coming from Troyer Performance. What all can you do to this motor for some HP? Without tearing into the motor, all bolt on stuff for now. I'm Looking at getting the E-Fans, headers, custom exhaust. I need help. I wanna beat up on some Camaros, Challengers, an some Mustangs

 

How much boost will you be running?
In order the beat a light car with that heavy truck you'll need to be around 10 to 12 PSI.
Long-tube headers, high-flow cats. true dual exhaust. and the E-fan should get you about 35 more rwhp. Might pic up another 20 with the custom tune.
That's about all you can do for bolt ons.

 

Sorry it took me so long to reply, just waiting to see if anyone else chimed in. Yes it will be at 10 lbs boost, custom tune, long tube headers, free flowing cats, with x-pipe into true dual exhaust, and e-fans.
Is there anything else I can do to get anymore power?

 

I would say that's it for bolt ons.

I run 4.10 gears in my truck. Helps get it off the line a little quicker.

Oh , and I run a Performance Industries triple disk lock up torque converter that takes about 1/2 second off of 1/4 mile time.
