Any have the RIPP on their JT yet and whats been the experience so far ?

[DAVECS1]

Update on my friends Ripp with the new engine, and they still can't get it right with the tune. He says he's over it, and is looking for a diesel.
Not sure if it's mechanically sound or not? He had a tuner shop install the new crate engine and re-install the Ripp, so I'd presume the install is legit. Sounds like the problem is tuning, and cannot seem to find anyone to get it right?!

I would be happy to look at the data and possibly tune it

I will let him know, and get back to you.
Was going to reach out to you anyway re my JT and a magnusson/tune. I will dm you with some questions I have for that.

New to the JT forum, but have been over on the JL forum for a few years. My friend put a Ripp on his JTR last summer, and blew the engine in the first 500 miles. Never could get the tune right with Ripp, spent 1000's trying to diagnose the issue, then finally discovered all 3 rings on the left bank were damaged and cylinder walls scarred. They just buttoned up putting new engine yesterday, and pullied down for less boost, so I am anxious to see how this set up works.

I short, yes, but the cause of the actual damage was never really discovered?!
Being familiar with other FI on corvettes and Ls cars, my guess was too much boost; but I don’t really know?!

My guess knowing what I know now and a very super brief description of the issues, would be variable valve timing not set ideally along with ignition timing causing brief moments of super high cylinder pressures, the lock the rings into the cylinder wall. Once i got airflow correct I logged brief instances of knock and fuel derate along with a lean condition. Extensive logging of the cama during this period showed they were decreasing overlap at almost the exact opposite time that would be ideal, and adding timing. This would make since on NA cars as you want some of that at accel and WOT. But not when you are adding to you manifold pressure and now those operating conditions are mid power band.

This RIPP Supercharged JT Gladiator was driven cross country, pulling a trailer, with the PCV valve installed in the crank case vent line backwards. Hours upon hours of driving with boost pressure entering the crank case, wreaking havoc on every internal component on that engine. Weeks of emails followed without any of the requested photos, data, or tests performed on the vehicle to conclude any sort of direct failure point. It is explicitly stated in the instructions that failure to install this part correctly will result in crank case pressurization. Ring failure due to a pressurized crank case led to scored cylinder walls and low compression on the drivers side cylinder bank.

There was no tune to be fixed. The engine was seriously damaged, the vehicle was continuously operated, and none of the diagnostic information we requested was given for weeks.

We do not do custom tuning as, like nearly all aftermarket manufacturers, the tuning team is simply not situated to handle that for the amount of customers we have. Our tuning team does handle diagnostics and adjustments for specific scenarios, such as a vehicle being driven from sea level up to a few thousand feet, but if custom tuning for more power is asked for we direct customers to seek a proper dyno tuning session.

There's always two sides to the story, lol

You are correct. It was also on 37's, equipped with 4.10 gears, pulling a 7000 pound trailer, and was driven for over a year with low compression on 3 damaged cylinders due to the PCV being installed backwards.

I said I would post updates and its been well over a year of install , decent amount of hwy driving and decent amount of off roading :


1)Still recommend this to those interested
2)Tune has been solid and no cels and I run it hard at very high evaluations (9k)
3)Awesome power still
4)Around town getting about 12mpg
5)Hwy very nice and around 18mpg
6)Use to have squeaky belt on cold start for a bit but that has gotten a lot worse lately . Its actually very annoying and takes a bit of driving before it goes away. I guess its way worse when I haven’t driven it in a bit on cold start . Right now this is biggest complaint with this setup

I’ve had my RIPP on my 2020 JTR, 35’s, 3.5” lift for about 1500 miles. I love it for the most part except the fuel mileage went down (~13mpg on 91) and the squeaking you mentioned is the same on mine and is horrible. I’ve narrowed it down to the idler pulley on the supercharger unit. Contacted RIPP and they are sending me a new one. I’ll post up when I get it installed with a result. Also I periodically get some codes indicating a rich mixture, been trying to find a tuner local ish in New Mexico.

Purchased mine and recently got it back. About 200 miles on it so far. Taking it easy and trying to be extra with break in period. I did have SD Racing out of greenville sc do the install and dyno tune. They had several error codes throw initially but dialed everything in and so far everything seems to be fine.

I run an AMC 401 in my 70 Javelin with the Procharger D1SC and have to also get the intake out from under the hood. I don’t use an intercooler with 14 lbs of boost because I run E85 which really helps cool things down. Are you going to try to get it on a dyno? I would be curious to know what you are getting out of it.

Im NOT a mechanic, but I have a buddy with an 875+ hp Ford Raptor - Coyote motor + Supercharger, its an absolute beast. He was told to run E85 because its "better" and now 2 years later the truck cannot pass smog, so now they tell him the E85 destroyed his cats and they must be replaced and it needs to be re tuned.

To be fair... running e85 you really shouldn't have cats in the first place.

*I'm not a mechanic but we run e85 in one of our cars and was advised by the shop to run it cat-less

 

[Shootist]

I can’t really comment on E85 and what it might do to cats but it sounds like the tune could have been too rich. I am just glad I don’t need to worry about cats in my setup.

If that's true, they never told him that. All I can tell you is they had the engine professionally built and tuned. The trucks had a TON of mods done to it and they never mentioned to delete the cats. Now hes having issues with the tune and trying to pass smog

I wish the newer once could run the supercharger... it's a shame the new GPEC's haven't been cracked yet.

Perhaps due to the state (cali, nv, ny, va, etc) the shop is legally required to keep cats on, or at the least not mention anything to do with emissions systems to maintain a compliant business, we're in GA and outside of the 13 counties that touch Atlanta, cats aren't required luckily.

We are both in Las Vegas. It's a daily driver for him and so I assume cats are required here. I drove the truck the other day, Jesus is it fast and loud as hell. It literally sounds like you're at a Nascar race when he goes by full throttle.

I can see where e85 and cats could be a problem and also just considering the use case for the catalytic converter it makes little sense for them being present since alcohol contains far less carbon than Dino fuel. I read an article also talking about how e85 and ZDDP in some oils is also extra bad for cats. Thank goodness for old cars.
