what up everybody, i have a 2003 ford f150 "boss" edition and i am looking to buy a procharger kit. i would like to know if anyone could help me, what is the maximum horsepower that my stock internals can hold.. any info would be great.. thanks guys

 

HI!... 400-450 RWH.P then your rods will break and you will ventilate a block. At that power level any 1st gear kickdowns where the RPM climbs instantly, will brak a rod. The LIGHTNING guys know this way to well.

 

With fuel-system upgrades:
You can expect somewhere around 320 - 360 hp to the rear wheels.
And around 380 - 400 lb-ft. of torque.

I think it will be a bit less if you stick to the FMU that's supplied with the kit.

 

hey thanks guys, also what do you think i would run at the track on street tires with 300/402 wheel hp/tq. also so you think it would be safe to run a 75 shot with the procharger, cause right now i have a 125 shot....thanks
