dropping mine off tomorrow cant wait gas mileage or not NEED POWER quick fix to v6 without paying for v8

 

you will love it... i am getting around 11.5 mpg... but i also have 37's with heavy spyderlock wheels... i dont care i like having the extra power.. didn't really get the jeep for its great gas mileage anyway. let us know how you like it once you get it installed.. i would recommend also at least getting a boost gauge.. helps you see what is going on..

 

Just a quick note. I have had the SC about two weeks. It has not been all rosy but I want to wait until I have the JK dyno tuned next week to relate my experiences. I do want to say that the mass majority of my problems were self inflicted as a result of the install NOT and I repeat NOT because of Ripp Mods or any of the components in the system.

With an untuned system in my JK at this time I did laugh today as I passed a
F-150 getting onto a highway this morning. I was stuck behind a slower moving vehicle with the pickup blocking the left lane. The pu driver pulled ahead slightly which let me accelerate going up a hill and "slip" through the window he had created on the 4 lane. This all occured in about 1/4 mile. As I cleared the front of the pu I glanced at my speedo which was happily moving toward 85mph! I was to say the least speechless! I had been watching the boost gauge and methanol light and didn't realize how fast I had accelerated. I am running 35"s with a 3' lift. Mileage looks to be settling between 13 and 14 mpg (closer to 13 than 14).

More on this next week.

 

I have a PM in to RIPP and assume that they're getting everything set for the release of the headers, but back on topic DiabloSport has their Trinity tuner out now and apparently in the hands of a real tuner (the human kind), you can reprogram the ECU to essentially accept any variables you want, which should mean that a shop like RIPP can use that and completely do away with the Black Box all together. 99.9% of the time I never have an issue, but once every few months under the same exact set of circumstances I throw the lightning bolt when the Jeep freaks out that I've stomped on the gas to get on the highway and then immediately back off just prior to it shifting gears (auto). It's not much fun to have restart the ignition in DC rush hour traffic on the beltway. The Trinity is expensive at around $600, but if it can optimize the great product RIPP already offers, I'm in for one (and a set of headers too). Those two things, plus a real dyno tune from RIPP and I think the package would be as close to perfect as it gets (it's already great right out of the box).

Edit: And if RIPP thinks it's possible to do that, I definitely volunteer to be the guinea pig and see what can really be pulled out of the 3.8 when the auto trans and the ECU aren't being finicky.

 

Good to hear from you again Sahara Black! Yeah, I have the 6 speed and I actually have an issue of running rich! When I blast onto a highway up a hill (only) if I miss a shift or shift too early and the engine boggs down I get a flashing engine light (yellow engine block thingy). From what I can tell this is a warning that the CAT's are overheating! I can throttle back (or if I am lucky if I am at the top of the hill) coast a few hundred yards and the light extinguishes on it's own. I am hoping the tuners can fix this. I bought the tuning software from Ripp and have a computer all set up to tune (but I don't have a clue as to what it's telling me.) I found a tuner near St. Louis that does MB, Porsche, Ferrari and about everything else. The have 2 dyno's one of which is a chassis dyno so I have HIGH hopes. We'll know by this time next week. In stock form this thing has more than compensated for the bigger tires and lift but it leans out and goes rich at some odd times.

 

Is that what it's doing? Going lean? I don't have much of a clue when it comes to these things, I just know that with the auto if I Stomp on it to get up to highway speed quickly (and it certainly does that really well), and then take my foot off the gas at what seems to be right before it shifts gears, because the traffic has slowed all of a sudden (or did I just catch up too quickly? lol), that that is when it happens and that's the one and only condition in which it does. It happens so rarely I can live with it, but man would it be nice to not even give it a second thought ever again.

I'll look forward to your reports on how your tuning goes Fathom, I've struck out around me getting it done, so it's a road trip up to RIPP to get it done when they get back to me. I'm looking forward to checking out their shop and seeing what kind of numbers they can pull out of my JK.

 

We won't know for sure until the dyno tune but if I am at almost WOT but not full WOT at 3.2K rpm the engine stutters VERY briefly (jeep jerks for a second) before accelerating again. It was a lot worse when I first got it back from the installer. The guy who installed most of my kit said he saw a sudden drop off of fuel at that time but he had seriously miswired it (sending incorrect signals to the black box)! I had to rewire it and now I get just a little hesitation but it's there as described.

Once the engine boggs down if I keep my foot in it it goes rich and I get the flashing check engine light (no code). I (and the import tuner in St. Louis) think the computer is trying to add too much fuel at that point and it's going rich causing the CAT's to heat up. He (the tuner) says both conditions are very common with superchargers and relatively easy to deal with with the proper software and a computer. Like I said, I'll know by Thursday.

(this is a lot more complicated (and expensive) than the MyGig issues! )

 

I had mine installed last week and all is good no lights little hesitation shifting but rolling off usually helps i will say i have the sprint booster on my pedal for the ETC and what a diff it has 3 mods red , green , and stock and with the charger you def feel the diff it works pretty seamless on red mod. On highway sometimes go to green mod so it doesnt kick down as quick gives you little more pedal my opinion its a must have gives good response. I had EXTREME VEHICLE BUILDERS in conneticut do install they ran dyno before and after before was 149 rwhp after was 214 rwhp thats with 35" KM2's with 5.13 gears its about a 40% gain in power the jeep is a blast to drive and has plenty of go its not a rocket but its fast enough keep in mind its a jeep you can go to EXREME VEHICLE BUILDERS web site on that you can go to their face book for pics and more hope this helps

 

I'm interested in the sprint booster ... what exactly does that do ? i have the ripp supercharger.. works great.. i do keep getting a check engine light for o2 sensor ? I'm not sure how to fix that.. comes on about 30 mins after Ive been driving ... i sent ripp and email but havent heard anything yet ?

but the sprint booster sounds interesting.. so i guess that works well with the supercharger ?

also what octane gas is everyone running in their jk with the super charger ?

 

Im running 93 and the sprint booster takes the lag out of the pedal because new jeep are controled by module not an actual throttle cable you have lag in pedal booster get rid of that it seems to hiccup a lot less if any with booster again all it is a booster for your pedal adds no power just alot more driveable takes alot less pedal to go and the power seems more available takes two minutes to put in im buying one for wifes car. i have seen more driveability improvements from this versus cold air intake and exhaust beleive it or not it was worth the money before never mind since supercharger was installed its even better and in no way do i sell this item i just think it works great hope this helps
