Supercharging A GT's 4.6-Liter For An Extra 200 Horses- HorsePower S12, E13

The late-model Mustang GT makes decent horsepower, but decent isn't enough for the HorsePower guys. They take a GT's 4.6-liter engine, add a new short block, and a Roush supercharger with a goal of adding about 60% more horsepower!

PARTS USED IN THIS EPISODE:
Enerpulse ,Inc.: Pulstar looks like a spark plug because it was designed to fit into the same hole in your engine. But, internally, Pulstar is very different, incorporating a pulse circuit no spark plug has.
Pattons Inc.: Nitrogen generator.
Roush Performance: This kit comes with a 2.3L TVS supercharger with black finish, upper and lower intake manifolds, an intercooler, a low temp radiator, a cold air intake system, a dual 60mm electronic throttle body, a unique fuel rail with 52 lb/hr fuel injectors. Also supplied with upgraded short block assembly.

According to the guys at Brenspeed, you are right about where you should be, with stock internals. Rule of thumb, 450 RWT is about all you want to send. Horsepower is irrelevant, when it comes to breaking parts. It's the torque, off the line that breaks parts. Mostly connecting rods. Horsepower is developed at upper RPM, torque down low, when the most stress is created. Again, this is just Brenspeed's word.

[@sherylellingson3538]

There are many reasons people build cars, other than making THE most HP. Considering the 18-19 GT's start with 460HP, making 500+ isn't much more than a CAI, headers and a tune. I personally prefer the S197 look over the S550. Plus, doing all the work myself, gives me some sense of accomplishment. Buying a 500+ HP car only takes money. Doing the work yourself, takes skill, patience, and knowledge.

Nice idea what about the rods that like to bend on a stock engine

[@sherylellingson3538]

Stock rods are perfectly capable of handling more horsepower than that. It's the torque that you need to keep in check. Any torque over 450 at the wheels, is bad for the stock rods. Everything else in the stock internals should be fine.

[@Prestiged_peck]

That kit was good fr waaay more they just didn't run the boost up

[@JuryRigGarage]

They were very conservative with this one. With that power they definitely didn't need a built motor, but they can easily turn it up since it is built. Beef up the intercooler system, basic bolt ons (intake, throttle body, pulley) and a tune they could easily be making 600whp

[@Prestiged_peck]

@@JuryRigGarage yeah all they needed for that power was a good ring gapping. That built shortblock was probably good for 650-700 if it had a stock type crank, If it's a forged crank in there then it's probably good to more like 800-1k

When the animation goes backwards it’s a misrepresentation and doesn’t serve anyone.
