Your not getting anymore power from the 3.7 then what it already has. It's a Jeep not a Ferrari,it does it's best work at 5mph or less. You want more get up and go re-gear to 4.10's,the only way. |

for the most part true. you will see SMALL gains with air filter/muffler swaps and maybe a few other things, but just not much out there... |

I used the stock eaton blower from my Cobra and fabbed an intake/adapter to mount the blower in place of the stock plastic intake. I'm running cryo treated forged internals with AirRam cnc Street heads, solid lash adjusters, custom grind cams, upgraded valvetrain, and water methanol injection. I'm running 8psi until I get the bugs worked out. I can smoke my 245's from a dead stop through 1st and 2nd, lmao my 250k mile 42rle didn't like that. The upgraded one from PATC seems.to.be doing good. One thing I'll mention...it ain't cheap. I did all the fabwork and already had the blower so I cut down on a lot of costs.

But yes, the stock transmissions and axles are going to have a bad day as soon as you really put that kind of power to them. It's not what the engine nor the rest of the vehicle was designed for; therefore, you have to redesign the engine and the vehicle in terms of components. |
