My RIPP supercharger experience.
Monday of last week I took the Jeep to RIPP to have the supercharger installed. I picked it up this past Monday. Summary comment: Awesome!
4.3 0–60 yesterday, in the heat. The best I have ever been able to get in the heat was 5.0.
Earlier this year, on a cool day and a slight downhill slope, the best was 4.5.
The odometer reads approximately 1,000 miles. I am told that when I pass the 2,500 mile mark the jeep will “wake up”. I will post when that happens.
The transmission shiftpoints have been changed. At first I didn’t like the upshifts (first time when I punched it at 70 mph it did not upshift [felt like it hit the rev limiter]; the next time it shifted smoothly). The first time I tried the 0-60 it went 4.6 (shift from 1st to 2nd was slow); subsequently, that shift was crisper (which is one reason it went 4.3).
It wasn’t until after the above experience that I read the Instruction Manual (I didn’t think that was a high priority, since I didn’t do the install). Lo and behold, page 2 discusses “…transmissions may not up shift at full throttle………….end users may….lift to shift……..So even that was covered LOL.
Ross explained that the tune reset all of the PCU’s learning regarding my driving habits.
I will keep an eye on the shifting, and I will post an update after 2,500 miles.
I was very impressed with the quality and attention to detail that I saw and experienced. I am particularly impressed by Ross’s attention to detail, the time he is willing to spend explaining and answering questions, and his philosophy of providing added power in a conservative manner – always minimizing risk of harm to the motor.
For those who plan to do their own install, the manual is very well done, with detailed instructions which are accompanied by 144 color photos.
I am really happy with the Jeep!
