Hi all, I just ordered my jeep and while waiting for delivery I am stewing on what mods I want to do. My wife also ordered a Rubi but with the 2.0L turbo. On the test drive the difference was like night and day; even though, both the pennstar and the 2.0 have similar peak torque and HP, the 2.0 gets to peak torque well before the pennstar and is a much quicker engine. I went with the pennstar because I hate automatique transmissions but I am jealous of the 2.0's performance. I was thinking about installing a super charger to soap up the pennstar. What are the downsides? I have heard really good things about the edelbrock E-force on JKs. People are saying that it doesn't harm gas mileage and the added strain on the motor is minimal, which sounds too good to be true. The jks have the same pennstar so I figure it's only a matter of time before they release a version for the jl. One big concern I have is wether the supercharge will harm my off road capabilities. For example, am I increasing the chance of sucking water into the engine on a water crossing? What does everyone think?
