    Sprintex Supercharger Intalled

    Well, after a few years of saving I managed to install a sprintex supercharger onto my 2016 JK. I had a local shop that does performance mods and tuning do the work, and as a plus they seemed to have had a bunch of experience with supercharged jeeps - mainly magnuson and ripp.

    Currently I am on 35s with 3.73 gears, and the Socal hills cause me to shift down into 4th and 3rd quite often. During certain stretches of freeway going to vegas, the jeep is literally in 2nd gear just to keep up at 60 MPH for an uncomfortable amount of time.

    I do know that gears would certainly help, but for the price difference of gears vs a sprintex I decided to try the supercharger first and then see if I wanted gears afterwards. Plus, sprintex offers excellent rebates on the order of $750-$1k several times a year, and that combined with a vendor coupon I made out with quite a good discount on the kit overall. I paid ballpark $4400 for the regular sprintex kit after the rebate and discounts.

    As a little background, I do have experience owning and tuning supercharged vehicles. My first was 2003 cobra mustang back in the day with a roots style positive displacement blower, a very similar blower compared to the sprintex which is a twin screw. Positive displacement blowers make boost instantly, which provides excellent torque and horsepower gains at the lower RPMs for crawling and daily driving. They do not need higher RPMs like a turbo or vortech style blower to make power.

    This video has a good explanation of various forced induction, with a bit of cheesy humor thrown in:

    Performance gains were INSANE! I dyno'd 366 RWHP on 35s and 381 ft-lbs of torque after some custom dyno tuning and some other mods, which if you take what a stock jeep dynos and assume a 29-30% loss I'm making over 500 crank horsepower. With a thermostat change and some fan settings to keep things cool the jeep hovers around 185-190 degrees when making boost while climbing up freeways which is about 30 degrees cooler than stock and I imagine significantly cooler than what most stock JKs are running.

    With just 2-3 lbs of boost I can now accelerate up highway freeways at 2k RPM with barely any throttle input. Of course, being able to floor it and spin 35s is just as fun as it sounds MPG is about the same in the two tanks I've filled up, despite the WOT pulls for dyno tuning and some fun runs. At this point, I am really glad I didn't do the gears and also upgraded the brakes to pro-grips beforehand.

    Cool.

    One thing though, unless things have changed, the Sprintex S.C. is not CARB approved, meaning you can’t register your Jeep in California.

    This kit is carb approved, under CARB EO D-695-1.

    The SPS kit is not.

    Great. When I looked into it a few years ago Sprintex was not carb approved.

    Interesting. How’s the supercharger whine? I know that’s the biggest complaint here about them is the constant noise they make

    Gears would have been less than half that price and would have improved your situation. For 4400 that seems like a waste... I would have saved a few more bucks and gone with the dynatrac trail leader package with 4.88 or 5.13 gears and improved my ride and the strength, especially since you have a D30 up front.

    I have a D44 up front. Besides, better axles and a slight regear are in my future anyways.

    There is no gear set in the world that can provide the performance gains I have without jacking the engine rpm through the roof.

    You spent $3400 more than a rehear. That is not in the same cost range and not “just a little more”. Fucking stupid.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
