2000 Wrangler

My review for the TJ supercharger kit, I’ve had the kit on for 2 years now without one problem on a 4.0 with 125,000 miles on it. Kit was very straight forward to install and if you had any questions whatsoever you could call Mark over at BT and he would walk you through it. I’m from the Chicago suburbs so I didn’t really purchase the supercharger kit for higher altitudes or anything but for actually going 4 wheeling and taking it up to the Silver lake sand dunes in Michigan. And man the power difference is incredible on the sand which ya need more power than stock to really fly through the dunes. I’ve had multiple people come up to me at the dunes and asked if I had a Chevy small block in the jeep or even an LS and just responded with a supercharged 4.0 and they were amazed at what it could do. I’m writing this review for all the sand running I do with the keep and how it attests to how reliable this kit is, sand is all high rpm and works the motor and supercharger a lot more then just regular wheeling. The limiter is hit frequently and without care because it’s a reliable set up. Currently I’m running the regulars 5-6 psi pulley with the tune from BT but I’ve been talking to make abs recently just ordered some new stuff from them to get the boost to around 10-11psi for even more power on the dunes. So my jeep is running a Dana 44 front and dana 60 rear, 5.38 gears and a long arm kit with 37inch bead locks and the supercharger has no problem of pushing it up and down the dunes in 2wd. If you’re looking for more power in your jeep this is the way to go, if you have any questions just call Mark, he’ll clear everything up.

Got these for my 97 tj 3.1l stroker four banger. Was shorted 2 bolts but the hardware store had 2 5/16x18x1.75 inch grade 8 Allen heads. Installation was a breeze. Soaked the rockes for an hour in 10w30 brake in oil then swapped out the rockers. They fit with no modifications to the valve cover or breather tubes inside the cover. The fit is tight but so far no rubbing. I’ll take it apart in a couple days and look for marks. Power is a little better nothing to brag about but maybe in a few drive cycles the ecu may adapt more. It revs up in neutral twice as fast as it used to though. I have a head and intake that I ported and polished which I will be installing in a couple weeks hopefully that wakes it up more. I currently have a custom ram air scoop piped through the inner fender from the air trumpet on the factory air box to the spot between the bumper and fender, a polished 4.0l throttle with a matching spacer (which made a huge difference), my thinking is it smoothed out the map sensor reading as the 2.5l manifold vacuum pulses quite a bit. Also 4 hole larger injectors and deral electric fan. Exhaust back pressure is 4psi max.
So all in all they do help just not as much as I would have thought but still better. 😊

(NOTE FROM BOOSTED TECH: We did refund Kurt $5 for missing these bolts; we do our best to get it right 100% of the time, but if we don’t for some reason, we still aim to do the right thing!)

1997 Wrangler

I took the TJ to BT in Denver, where Mark Cook had it for a week doing the installation. He also replaced my OEM radiator with a 3 core aluminum unit; all new hoses, coolant, belt, 185 degree thermostat. Additionally, my TJ is an early 1997 and had an intake manifold with unequal length runners, which Mark changed out for an aftermarket equal length runner model. Before taking it there, and as a result of Mark’s instructions, I did a compression and leak down test, and fuel rail pressure test. All were good, with leak downs all 98 to 99%. The Jeep has about 63,000 miles, and has done it’s share of trails, many at Moab, medium difficulty (max of 7 rated). During the final pull, the shop owner connected his laptop to the BT piggyback ECM, dialed up Mark C. in Denver by phone, followed instructions for logging on to BT’s website, and then Mark took control via the laptop interface, of the piggyback ECM program in the car, and did some final tweeks to the AFR and timing. I also installed the platinum plugs that Mark supplied with the blower, and I had him use the high altitude (small) driven pulley. I get a max pressure of 8 PSI and an AFR at full throttle of 12.4 to 12.5. Highway fuel mileage at 65 mph, 3,000 rpm, is about 12 mpg, so somewhat less than previously.
Before doing the BT installation, I had a shop in Reno do the following: dyno pulls for Before blower, HP & Torque; install an ‘A’ pillar two gauge instrument pod and an AFR and Vacuum/Boost Pressure gauge. We also converted the injectors to 4 hole from the OEM one hole units. It also has a header and high flow exhaust system (plus a bunch of off road chassis stuff).
Results: a final dyno pull showed a 40 hp and 70 lb.ft. gain, for rear wheel HP of 200. All power transitions are smooth and linear, and power is excellent. Mark did a first rate job with the installation; his workmanship was outstanding. I have about 1,000 miles on the blower installation, and am totally pleased with it.

After years of work Jenny the jeep was closer to being finished then ever! But several test runs around the town later I felt like this dual purpose monster was more like a crawler only. I found my solution in Boosted Tech with a simple bolt on system that is all plug and play. Where before she huffed and puffed with the old tired 4.0 now lights up and scoots. Not bad for a bolt on. Id say best power adder for the dollar no doubt. Nice smooth power that really has impressive sound. The kit was clean easy to install with full photo included step by step instructions that had everything included but the spark plugs and they tell you which ones you need so don’t worry. Pick up dielectric grease while your there.

Customer service is top notch. Mark is the man that answered all my questions and even some none related questions about other projects. Looking forward to getting a higher psi pulley from them soon! Freshin her up then really open her up. I find all the power I need under 4000rpm. 5th gear is usable now! YOU GET TO KEEP YOUR AIR CONDITIONING!

Overall great! Had to wait several months to receive it but the wait was worth it! Took me about 8 hours to install. Took my time and made sure everything was correct. Turned the key and everything started up with no issues.

Found this site because I was looking for a solution to make my Jeep more powerful. Contacted Mark to get some information about how it all worked. After talking to Mark I placed my order.

The install was easy took me about 8 hours to do and any questions about the install were promptly answered. Once it was all installed, i contacted Mark for a remote tuning session. He Wanted to make sure the tune was what you needed. After it was all tuned it made my 2.5 jeep preform like a six cylinder. And not to mention it has a new mean sound coming from it that make other jeepers wonder what I did to the motor. When you open the hood to show them what you have, right away they see the eye candy.

If you are looking for ways to make your 2.5 Jeep run like a six cylinder I suggest you look into this supercharger. You will not regret the purchase.

The service is exceptional and Mark and his team are very knowledgeable.

Thanks to Mark and Chris for the help with the tuning of the new supercharger. My 2008 Rubicon is really a beast now with the additional power added. I bought it primarily for pulling a trailer because the 3.8 is somewhat underpowered. I highly recommend this company for their product’s ease of installation and customer service. It is nice to know you can call on them locally to ask questions and do the tuning locally. Other companies have you send your ECM into them to get flashed. Mark can do it here in an hour or two. Nicest people in the business!

It’s been about a week since I completed the install of the supercharger on my ’03. I love my jeep and the things I have done to make it mine but I was having a tough decision of either putting more power in it or moving on to a truck; I would have to say I am extremely satisfied with my decision (it helps that the supercharger whine has a nice giggle factor to it). Between the ease of installation i.e. everything bolted up with out any drilling and everything needed as far as parts for the install came in the kit, the assistance of Boosted Tech, and the performance that my jeep has gained, I am highly impressed. Living in Florida, having any large inconveniences would be difficult; but due to the hard work of Boosted Tech, and aside from a small year crossover with the ECU that will be rectified in the next week (vehicle is drivable, there is just a small amount of power and lower end response left on the table, none of which is the fault of BT), at the young age of 19 this install went flawlessly. I recommend BT, if not for the product quality, then for the customer support from its personnel. I love supporting smaller shops, and it’s safe to say I can add this to my satisfied list.

1998 Wrangler

I just finished installation and tuning of the BoostedTech supercharger on my 98 Wrangler with 4.0 and a manual. With 3.07 gears and 31 inch tires, I have gone from being unable to break 60 mph uphill on the highway to having to worry about a ticket on the highway! Installation was a breeze, Mark and Christopher were very knowledgeable, very patient, and very helpful, and a couple of glitches were taken care of very promptly. My Jeep is used 90% on road, and 10% off road, so it is a MUCH more usable vehicle now, as it a much more capable daily driver.
I am an anesthesiologist by day, with a car habit as my therapy. I have basic mechanical skills and tools, but I am by no means a professional mechanic. If I had it to do over again, I would choose BoostedTech again. They deserve the praise in the reviews not only for a superior product, but for superior customer service!

We took Eugene out for his first supercharged trail ride Saturday. We went up into the mountains above Logan, Utah. Steep, rocky trails at altitude to see what this supercharger can do. Eugene is a 2004 TJ Rubicon, running the medium pulley, Edge 62mm throttle body, cold-air, stainless steel headers and a 2.25” stainless steel exhaust, auto-trans, Dana 44’s w/ 4.10’s on 37’s with a 5.5” long arm lift and an additional 1” body lift, fully caged and armored. No added tuning over Boosted’s set-up. I also have a boost gauge and an AFR gauge to watch what’s going on.

The supercharger runs incredibly smooth. It transitions over from normal aspiration (vacuum) to boost seamlessly. You put your foot down, listen the charger’s sweet sound and watch the boost climb. The jeep effortlessly accelerates like it even isn’t trying! It accelerated even and strong, like an electric motor. Very linear, no flats spots. I can now drive at 65-70 mph again in overdrive, something I couldn’t do anymore when I went to 37’s. Off-road, it’s like having a small block Chevy under the hood, but without the weight. There’s always power when you need it. The boost does not come on hard, it comes on very controllable and there is no hesitation or lag. Throttle control is so good you won’t lose a bit of traction when you need that extra power.

We took Eugene up to 10,000 feet and the boost was still significant. After over an hour of climbing up from 5,000 ft Eugene was starting to get hot. Never over-heated, nor even got into the ‘red’, but still does run a bit hotter. I have hood vents and cold-air intake ports on my hood to help control the heat, a quick hoods-up stop at the edge of the snow pack quickly cooled the motor. So after spending the day climbing, running around in the forest and snow, then heading home, I noticed my gas mileage only went down a few mpg’s. I suspect that if I were to drive ‘normal’ instead of playing with the supercharger all day long my mileage will be close to the same. Bonus!

The install was also smooth and easy. I took my time and did it over 3 afternoon after-work sessions. Didn’t want to waste the weekend under the hood, rather be behind the wheel! The vacuum/boost lines probably took the most time to figure out and connect. Boosted’s instructions will get you thru it. Some jeeps have more or less vacuum lines and may seem confusing, mine had at least one extra line I had to figure out, and with a boost gauge made it two. No problem, Boosted’s instruction’s talk you thru what’s vacuum and what’s boost. Anyone can do this install.

It took a little time to get my hands on this thing. Certain years have certain ECU hurdles to overcome. But Mark and Chris know their stuff and will make it happen! The addition of this supercharger has been, by far, the most cost-effective performance addition I have made on any of my vehicles.

A happy customer,

1997 Wrangler

HUGE THANKS to Mark and Chris for making this happen! First of all, I did call Mark and Chris a few times while installing to ask a few questions. They always answered and were very helpful. Great customer service.
I have a 97 Wrangler Sport 4.0 manual trans, 128,000 miles with 4.56 gears and this thing is quick!
Installation took me roughly 20 hours but this was my first endeavor with forced induction and this was a leisurely weekend job with other distractions.
The kit came with everything for the install. I could definitely tear it down and put back together in just a few hours if desired.
Stock internals and running safely at 7 psi and using the tune that came with the split second FTC. So NO adjustments were necessary for me living at altitude of 5300 ft.
There is a huge difference in how well/smooth it takes off from a stop and throttle response is amazing! Give it WoT and this thing takes off! Have not hit any trails yet but I have no doubt in its capabilities.
This is a daily driver jeep and I love every minute of it.

I ordered my kit from EBay on Dec 13 , 2016 and I didn’t get the kit until Jan 13, 2017 due to an issue with the tuner. Apparently Mark discovered a problem with the Split Second tuner for the 05/06 Jeep Wrangler TJ. I spoke with Mark about the tuner issue several times during the month that I waited. I got the kit and it was well packaged and appeared to be good quality. I started the install and got the supercharger mounted in about an hour. I did notice that the “tub” sat right on the injector rail, hopefully it will not be an issue later. The bracket bolted on perfectly. The belt was kind of a pain but it worked out nicely. Got the SS tuner installed with no issue. The only problem that I found during the install was the throttle cable bracket. The throttle only went half throttle. I removed the bracket & elongated the holes, then adjusting the bracket per throttle. My 2006 TJ runs well. No issues so far. I may need to go with the mid-boost pulley for more power. I live in Kansas and with the stock pulley it seems like it may need a bit more boost. I’m happy withe the BoostedTech supercharger kit. I will recommend it to all of the Jeepers here in the Kansas Flatlands.

I just want to say thank you to Boosted Technologies. They do a very good product. I love it. My supercharger in my Cherokee…I feel like I’m driving a completely different car. The power is excellent. It has a lot of more power. I just love it. It’s great. It feels like I’m driving a V8 very strong powerful car. Thank you very much Mark for helping me with this. I appreciate it, thank you! I am so happy with it.

BT-Supercharged 2006 Dodge RAM 1500 4.7

First and foremost I have to give Mark, Rick, and the rest of the crew a job well done. I’ve had this kit on my truck for a week now and can say WOW!! This truck ran well before but had a bad habit of kicking out of overdrive all the time. This made highway driving a chore. Low end power was helped by regearing from 3.55 to 4.10. However there was something missing. This kit was what it was missing. Highway manners are awesome, no more annoying downshift at the slightest incline. Low end torque is well, INSTANT!! It won’t hesitate to turn 35 inch tires or sling some mud. I have a 18ft goose neck trailer and compact tractor I pull on occasion and hope Mark will let me add how that goes next time I need to pull it. I have no doubts the extra torque will make that chore easier as well. The tech support is amazing and the people are real and easy to talk to. If I had 100 of these trucks I would put this kit on all of them. Absolutely filled the gap where this motor needed it.
I can’t give a honest fuel consumption comparison yet due to my inability to keep my foot out of it 🙂 I’m running 6psi @ 1000ft elevation with 3 in pulley. 2006 ram 1500 quad cab 4X4 4.10 gears and 35×12.5 pro comp tires.
Thanks again,
Kyle
Ft. worth

Got some needed repairs taken care of. It’s up and running strong! More or less magically bad ass while in boost. Impressive pull through sand spinning 35s like a boss! Thanks for all your help! TJ woke right up and I m wearing a smile ear to ear!

2001 Wrangler TJ

This review documents my experience with your Supercharger Kit. In short, nicely done. I purchased this kit in early September 2016. I received within two weeks. The product was well packed and included all necessary parts for my vehicle. I was impressed with both the quality and general appearance of the custom machined parts in this kit. After taking a deep breath, I began the installation process. I have slightly above average mechanical skills and found the parts fit well. I contacted you (Rick) about two times with some technical questions which he easily answered. It took me about three leisurely afternoons to complete. I was also detailing the engine bay at the same time. My guess, I could probably do it in about six hours if I worked straight through. I also followed the recommendation to get a lower temp sparkplug and gapped them down.

After installation, I turned the key and it started immediately. From my initial drive, it has performed flawlessly. I have a 2001 Jeep TJ with 60k miles I purchased new. The jeep has 3.73 gears and 29 inch tires. I have stock exhaust and a k&N filter in the stock box and am operating at sea level. Using an ultra gauge, I timed my 0-60 times after installation at 7.51 sec. I was not pushing too hard and think I probably left about 0.5 sec on the table. I have about 1000 miles since installation and again, no problems. The vehicle sounds and drives completely stock unless I put my foot down.

This is an impressive looking and performing kit. I’ll advise when I hit 10k miles. Again, Nicely done.

1997 Wrangler TJ

Jeep is great, runs real strong

2004 Wrangler TJ

Thank you for the support and an awesome affordable product! The supercharger works perfectly and the power difference is astonishing. I got the low boost pulley that came with it and don’t even think I need the med or high boost for my needs. The tuner came set up and was truly plug and play. It may need some minor adjustments but I have drove it so far with the tune on it! Couldn’t be more pleased.

Cherokee (1991-1995)

Dont know if i ever sent you a picture. going to run the smallest pulley and spray methanol. already beat a v8 explorer, 300zx, and a prius haha

Very pleased with results, excellent cost to benefit ratio. Installed on 2005 Wrangler TJ with73K miles, 4.0 L, 4.56 gears and 35 inch tires. Home is at 7400 feet altitude. With the standard pulley it is a much improved driving experience. Hills where the Jeep would lose speed at highway speed I can now accelerate up in third gear. Smooth and much faster acceleration from standstill to 60 MPH. Increased tire size to 37 inches without changing gearing with no loss of performance.

I just wanted to tell you how happy I am with the SuperCharger. First off let me tell you about my Jeep. It’s a 93YJ with a factory 4.0, 6 speed and transfer case out of a Rubicon. It has 1 ton axles and 5:13 gears turning 40″ tires. These things weigh 150lbs with wheels. The whole Jeep is 4600lbs. Needless to say it was way under powered for living in Colorado and just about any other place. To drive from my house in Durango to Silverton/ Ouray I would have to gear down to 3rd just to keep it around 45mph. Yesterday after swapping controllers, I was able to drive the same passes in 5th sometimes hitting 70mph! I was blown away. I actually had to back out of the throttle?! My girlfriend is the one who talked me into the SuperCharger instead of the V8 swap. I’m glad I went with the SuperCharger, it’s a torque monster. The girlfriend a keeper, by the way.
Off-road is just like on road. The SuperCharger makes tons of power that is usable almost all the time. It makes climbing easier and keeps the motor from bogging down. This is especially important when you wheel at 12,000 ft. It just plan works everywhere.
Yes it has been trying at times but in the end, it was well worth it. My Jeep is a Beast!
Thanks for all of your effort and hard work. You make a great product that I am proud to tell people that I have.
If you or anyone else need more info on my install don’t hesitate to call.
