A road trip with some 0-60 runs. You're updates have no info in them.

I'm interested in finding out if it delivers power between 60 to 80 MPH going up a grade behind a logging truck. It's scary spending 20+ seconds in the oncoming traffic lane trying to pass a even slower moving vehicle than me on a 2 lane highway.

Very cool. I am glad to see this. We are a ProCharger dealer (new dealer) but have yet to install one so we are looking for some real world, un-bias feedback.

Sucks about the Daiblo. We have been down their rabbit hole before. Glad to see you have it up and running!

The diablo thing is interesting. Once one realizes that the options on each page are not intuitive, it becomes less stressful in that you don't feel like you've already done something wrong. On the other hand... it would be great if it were a bit more user friendly. I'm working on a step-by-step for feedback to diablo and procharger.

I'm sure that, once you've done it once or seven times it seems obvious. Things like selecting "modify PCM" when you only want to back it up. An experienced person knows that a new i3 attached to a vehicle for the first time will make a backup before it modifies the PCM and THEN ask if you want to "backup only." Not clear in for a novice like me.

I know! My communication style is a topic with my counselor too! Don't judge....

The short answer is yes. I'm thinking a few 0-60s and an actual after dyno. Thinking a gopro or something on the dash and a view from outside....

I have a magnoflow axle-back that might sound different given the throughput.

I have a few lessons learned I plan to post as well that will save a self installer a couple hours, everything else being the same.

I can answer this, anecdotally, already. Our first drive included the "ridge cut" on I-24 in Chattanooga. It's nothing fantastic but it's a pretty steep uphill and curvy, a classic slow down on the interstate. We were blown away by the the high-end acceleration. Sounds like another video for posterity.

The sound of the centrifugal supercharger and blow-off valve was also pretty satisfying.

So how much money do you have into the upgrade between the charger, unlocked Ecm and anything else you have run into ?

Ouch, let's see lol.

I ordered the [complete] kit from extreme terrain for about list. They did give me a bit of a discount just for asking so that was nice. The helical gear set and black intercooler added about $200. It, of course, drop-shipped directly from ProCharger. It arrived in about 8 calendar days, less than the two weeks advertised.

The PCM from diablo was purchased at list price, so ~$650.

I purchased a hose for the blow off valve (problem with the supplied hose) some sealants, grease and spark plugs. The plugs weren't cheap, about $120 but they are NGK iridium plugs, colder than the OEM.

All in, probably right about $7500. Not cheap but not mind blowing given the change.

It's probably worth noting that we (my 12 year old son and I) did this over one evening and one long day in our garage. A garage that has never seen any real work so tools and supplies reflected this.

I think the lessons I learned could save the next guy 6 or more hours.

I've been searching around online trying to get a deal on this SC and found a retailer selling the complete kit with helical gears delivered for under 6K. Not a forum vendor. Maybe KrawlOff-Road could match the price. I'm still waiting for more information before pulling the trigger on this and hope to keep hearing encouraging reports from Z on his ProCharger experience.

Any idea how much boost that kit is pushing out?

I had a brief stint with a sprintex supercharger. It used that same diablosport tuner which I think we can all agree is garbage. I'm pretty much boycottying any aftermarket add-ons that require a windows PC to configure.

That will leave you somewhat limited.

It's advertised as 7 psi. I have no reason to doubt that and yet nothing to back it up. Agreed on the tuner, like I mentioned, the tuner (programmer) was disappointing. It's especially notable given the price one might pay to get it alone. I believe it can do the job simply because the PCM itself is a pretty rudimentary computer (though doing an important job). That, and I have a lot of confidence in ProCharger based on previous experience.

THAT seems like a good deal all things considered. It's definitely a chunk less than what I paid (and I thought I shopped around).

Well, it looks like another SC mod has faded into the past with no real data about real world gains. They seem like a lot of work and money for nothing.

Damn, I saw this thread update and was hoping OP was coming back with dyno info.

I'm with you.

Could be just busy, but I must say I haven't seen too much in the way of success stories with these SC's.... I would love to see ONE.....

Spot on, I haven't been in TN since the August 15. Unfortunately, the vehicle will not fit in the overhead bin and I hate checking it. #airlinerules

It would've been nice to have it on US-1 in the keys last week,

I'm headed back from Oregon on a redeye tonight. I actually ordered a headrest mount (and a baby tripod) for my phone to record exactly what I said I was going to.

I'm going to one of two places for a dyno, depending on who can fit me in:

Custom Concept Motorsports: Welcome to Custom Concept Motorsports

In-tune motorsports in cleveland:
https://www.facebook.com/pages/Intun...25877767535432

I apologize for my geographically diverse employment and sweet vacation. Here's what I was up to while my Gobi was resting in TN:







Stand-by, more to come shortly!

Thanks for you info on this. Glad this is not another one just not working.

Enjoy the vacation,, life is short.

For the record... it's a lot harder to get a shop, in a little city like Chattanooga, to agree they can fit one in for a dyno run than you might think. I think In Tune Motorsports in Cleveland will fit me in, perhaps if I cater lunch. I'm flexible.

As noted above, I've been separated from the jeep since August 15, so... no. However, I am in the Charlotte airport headed that way.





The single mission of this trip is no longer to take my children to Destin. It is now to video some jeep supercharger shtuff. It seems my online jeep family has a strong sense of urgency.

Dyno Results

Dyno results for those interested. I should receive these electronically sometime this evening. Thanks to the guys at In-Tune Motorsports. It was a little tricky (or sounded so to me) to bypass the stability/traction control in order to get a proper run.

276 max HP
238 ft-lbs of torque

A little under 7 psi

HP was climbing steadily all the way to the rev limiter.



Videos from the dyno and such coming shortly.

Surprised it wasn't a higher hp and torque

Stock engine must be really sad

What size tires do you have on the Jeep ?

Yeah, not making quite as much as I had hoped but, it's more than I expected. Advertised output can be quite over-stated (like a CAI).

There's a video or two of the kit making ~300 Hp at the wheels.

It's important to remember that this is the measured output of one jeep on one particular Dyno. I expect that it's fairly accurate but such measurements do vary (so it could be lower or higher on the next dyno).

Tires are 315/70 R17 or just about 35."

The shop said that the tune from procharger was really rich so some simple changes there would make more Hp. As is, it is is a long way from lean and "safer" for the engine.

There is some power left on the table with the setup as is, plenty more with some minor adjustments. I just have to decide how much I want to push the drivetrain.

That is decent power, as you say not great, but decent. But we spend a lot of time below 3 grand, how does it do there?
What gearing are you running?

Here are a couple (rudimentary) recordings of city driving for practical reference. They're on my phone so I apologize for the quality and wind noise in advance. I tried to fast forward through the mundane.

I tried to capture some 0mph starts as well as some highway acceleration. Traffic wasn't cooperating. I'll try to capture some early in the morning when traffic is light and it's dark so one can see the speedometer more clearly.



Perhaps the best view of acceleration from 0 mph

The drivetrain is stock from the intake back. So, whatever stock gearing is whatever comes with the "unlimited" version is (I should probably know this).

For Sports and Sahara's base gearing is 3.21 gears. You can upgrade to 3.73 gears.
Rubicons have either 4.10 gears or many automatics come with 3.73 gears.
Also, there are a few different tire sizes stock, and tire size is part of gearing. Bigger diameter tires mean taller gearing, which means less power at the tires.
