It really looks like everyone has some sort of problem. I drive most of the time with a light throttle and below 3000 rpm. Mine is an auto. I think if I want to be safe the Ripp is the way to go. But if I want bottom end then I want a screw. I wish the Maggie was more sorted out. I love the scream they make when you kick them in the pants. I'm still deciding but yeah I am gonna do a speed run. I just don't know how high I will go.
Has RIPP also figured out the auto shifting? The instructions I got from them a while back state you need to lift to shift during heavy acceleration.Originally Posted by Gunner
That was from months ago, so it's possible this has changed. The last line, while I understand is a CYA statement, also worries me a bit.• Automatic transmission: Auto transmissions may not up shift at full throttle when driving in “D” (drive) mode, THIS IS a Direct product of OEM programming and not the provided tuning. In order to shift at full throttle, end users may either “lift to shift” by raising the accelerator slightly (partially). RIPP makes no claims as to the reliability of the transmission with the supercharger installed.
I am not associated with sprintex at all. I am a pilot for United Airlines. Sprintex is not perfect. As for the transmission problems. I really don't have any. If I go max blast it does shift by itself. Sometimes if I am just driving I do force the shift. I am trying to converse gas and I want the shift points where I want them. It's a personality defect.
Gas mileage has settled down to 14-15 mpg combined. If I gun it a lot it goes down to 12.
The only negative is that it does not like the cold. If temp is below freezing and I don't let it warm up for a couple I might have a misfire. If I let it warm up, there is no problem.
Why did I go with sprintex? Saved over a grand on the other systems and low end torque. It also looks good.
It seems like some people have no problem with the ripp and a few do. I think it is maybe the lift,weight, tires,gears combination that is a problem. The Jeep Canbus system is a total booger and the trans computer is diabolical. I am not sure what the answer is other than I was some sort of boost on my jeep. And right now I am just not sure who I want. The Ripp has the best track record overall in the industry and they use the Vortec head unit which is pretty solid. The Maggie and Edelbrock use the TVS1320 blower from Eaton which is a good unit. I would love to see the boost curves from all these units laid into one graph.
Can anyone confirm that they have a AUTO RIPP unit and do not have to lift to shift?
Are you running an automatic or manual
I have an auto.. Ross said that Ripps boss has an auto and that it shifts fine. I am going to look to see just how many I can find that are autos and doing good.
I didn't want to hijack the sprintec thread so I am going to post in the ripp one.
Thanks for this thread... Because of the positive information regarding the tune and drivability with the Sprintex 3.6 unit, I bought one today. I have a 2014 unlimited rubicon with an auto, so I'll be sure to follow-up with how well everything works. I'm pretty excited. I strongly considered a Motech V8 installation, but the price of the Sprintex made it a course of action worth exploring.
Speaking of the Ripp, I've read up on it and for a light weight sports car that lives in the upper RPM range, I think centrifugal superchargers are great. However, in a big, heavy SUV, I think the twin screw roots type blowers have a definite advantage. The off-idle power was a huge consideration for me. The peak power figures for the Ripp are very impressive, but not practical for my driving style.
has anyone actually installed and tested this thing? Do they guarantee that there will be no "lift to shift" problem? I mean really publicly guarantee it?
rgeorge33, please keep us informed about whats really going on. keep in mind, you are a poineer of this unit.
I was going off the original poster's comments. I don't think Sprintex has made any guarantees about the shifting. I'll report what I find, but I think the original poster's comments are very encouraging. My primary concern is the drivability on a normal basis. However, I'll let you know about the shift behavior once I get it installed and properly tuned.
