Pentastar + RIPP SuperCharger = SUPERSTAR?

[JeepLab]

Ok, I've done it. About a week ago I swore I'd keep my truck in the tac's green zone to give you guys an idea of the MPG increase with the SuperCharger.

Before and after install Everything on the truck is pretty much the same.

Before 12.7 mpg
After 15.8 mpg

Im figuring by the total miles traveled vs gallons required to fill again.

I should note, the After is Premium, and the Before is Regular gas.

i use 93 octane in Black Betty,

So the fuel costs more, but you should go farther per gallon with the SuperCharger

Fuel cost is offset by better fuel economy. I get 3 MPG better with the S/C.

Maybe someone will figure out down to the penny what the total cost difference is. Betty on regular got 13 MPG before the supercharger, and 16 after (premium). So the price difference is more than just the difference between regular and premium

Keep in mind, you will drive a supercharged jeep more aggressively than a stock unit, so you probably wont see a great MPG gain. Its hard to stay off the gas.

If the pentastars head issues had you concerned with the extra power-

Dont be. My JK was delivered Jan 13 of 12. Meaning it was built in december of 11 when all those guys at chrysler were busted for drinking on the job.

Also, When I installed it, we BEAT THE HELL out of it by racing across the country after, I dont know how many, dyno runs.

No on on earth would beat their truck the way we did and the S/C held up fine. And my head is fine. Believe me I was concerned too. I didnt want to sleep while we were driving to moab because the other guys were driving like the truck was stolen.

Here's the 0-60 clip!

Here's a fun shot. Im on my way to Rock Krawler at 8am on the NY state thruway, I couldnt believe how fast traffic was moving. I could completely cruise at about 90.

Look at the RPMs. this is on 37 inch KM2s and 4.10 gearing. Ungodly fast.

I slowed down to take the picture.

Hey all

I just coiled over at rock krawler. My sc is turning 37s now.

The power is still there. I'm considering gears, I've got stock 4.10s
