Magnum Powers Jeep Wrangler TJ/LJ supercharger Kit 2000-2006

This kit adds over 115 foot pounds of torque and 100+ hp to the tire. And our High boost versions can add 250 foot pounds of torque and 250+ hp to the tire! Please note, Jeep in their advertisements call out engine hp not wheel hp, which is about 25% higher numbers then wheel horse power. Most superchargers providers call out engine horse power as well so don’t let this confuse you. Jeep claims the engine makes 190hp and we are sure it does however a stock Jeep TJ produces only 125hp to the tire, that is a huge difference and can be accounted for by considering drive line losses, accessory drag and chassis components that reduce hp such as the exhaust system and intake components such as the intake tube and air filter.

A positive displacement supercharger for boost from Idle to Redline. No waiting for boost to come on, our supercharger starts adding boost from 500 rpm. Positive Displacement superchargers are known for making torque and low end power and that is what a Jeep Wrangler TJ needs!

Efficient water-to-air aftercooler system – No need to run methanol or limit boost and power as other systems do.

Our kit has a independent supercharger drive belt! Our Kit does not use the accessory belt to drive the supercharger. Instead we designed Magnum Powers kit with a separate supercharger drive belt so the crank and supercharger pulley sizes can be easily changed for boost from 5psi to 20psi. It would have been much cheaper to drive the supercharger with the accessory belt as all others do but we chose to spare no expense and run an independent supercharger drive system so the crank pulley could be made larger for lower end power and torque. This is a huge feature that no other supplier provides.

The Magnum Powers system is totally upgradable, if you want to start with low boost; for instance you’re on a budget, you can. Then later with simple low cost pulley changes you can increase boost as your budget can afford fuel injectors, fuel pumps, etc needed to support more power.

All fits under stock Jeep Wrangler hood, no need to install body lift kit as some do. All Hardware needed for Installation is Included.

For Off Road Only.
