Awesome, thanks!

So no problems at all since you installed, that's great to hear!

How much more fun is it to drive and how much faster do you feel it is?

Re: Thinking about an SuperCharger...

I can't really speak for the 5.7 heli setup with a supercharger but I have been messiing around with the RIPP SC on a 2014 3.6L grand cherokee...I'll give you the quick rundown of my experiences over the past 18 months with this setup:

1st installed with 33K miles on my jeep- installed the RIPP stage 1 intercooled kit running 7 lbs of boost- Easy to install and setup really...just required a few tweaks - I needed to add a catch can and a PCV valve as I was getting oil blowby that would cause misfire and knock codes to pop up ...but driveability was perfect...ran great and very smooth- overall the stage 1 kit was pretty good.

I originally dynoed my jeep stock at ~185Hp to the wheels- After installing the stage 1 and using the RIPP tune it pulled 290hp to the wheels...with a custom DYNO tune I was able to reliably get 320AWD HP to the wheels

to keep things in perspective I was running a 7 sec 0-60 stock...with the custom tune and stage 1 @ 7lbs of boost ...I was reliably getting a 0-60 of 4.6 secs

I drove it that way for a year and logged in over 13,000 miles...this was my everyday driver so I needed it to be reliable-Overall I was pretty happy with it ...I could hang with most any stock SRT with that setup..but I started to get bored so I started looking for a little bit more

I was able to get my hands on one of the RIPP Stage 2 Kits for the 3.6L setup - the stage 2 used the same blower but had MUCH larger piping/injectors and the stage 2 SRT intercooler. With the same blower and pulley the boost increased from 7lbs to ~10lbs because of the larger piping and K&N CAI

I was able to get a tune with that setup at the 420AWD HP to the wheel range...but I started chasing knock issues at WOT ...I tried getting them tuned out but never really was able to get it fully tuned out.

then I made the fatal mistake of swapping out the pulley for a smaller unit...under advisement of pretty much everyone here and from RIPP NOT TO do that...I did it anyways...and was pushing out 14lbs of boost...I was never able to get a successful dyno tune on this setup because of other issues...but it made HUGE power for a v6 ....but within 2 months I ended up blowing the motor...totally exploded it ...so my jeep has now been down for the past 3.5Months ...I am having a custom forged setup/engine built for my Jeep now...still the 3.6l but with all forged internals to handle the 14lbs of boost

Bottom line is that if you stay within the ~7lb range you'll prob never have any real issues...and as far a driveability...it drives like stock pretty much ...no surging or anything weird like that ...just faster ...like i said though...this is my experience on a 3.6l setup


The 1st pic shows the stage 1 kit...then after that the pics reflect the stage 2 upgrade

here's what it sounded like with the stage 1 ...it's MUCH louder on stage 2 because of the K&N

Re: Thinking about an SuperCharger...

8lbs Boost on a 5.7L is no problem with the right tune. I ran my Challenger at 12lbs with different cam and AJ Berge "Hemituner Performance" tune. I ran a Magnuson Supercharger also. Dynoed at 540 HP and 510 TQ. Ran for 30K miles no problems daily driving and tracking.
It is all in the tuning and AJ is second to none. Another great tuner is Mike @ OST.

Thanks for the update. Talking cams I am thinking of a 6.4 cam should be a direct swap and won't destroy the idle.

That is pretty gangster!

I want to think that it'll be enough with "just stage 1 kit" but, lol, I'll probably be like you and over do it!

Re: Thinking about an SuperCharger...

Not discounting any of YOUR experiences but I have a few questions.

ajag states: I needed to add a catch can and a PCV valve as I was getting oil blowby that would cause misfire and knock codes to pop up ...but driveability was perfect...ran great and very smooth.
Q) Where the misfires felt while driving?

ajag states: 320AWD HP to the wheels. I could hang with most any stock SRT with that setup.
Q) My 5.7L makes 304.7rwhp@5125 and 337.6rwtq@3686 and I don't come close to beating my friends stk. 2014 SRT Jeep. How are you able to achieve that with 320rwhp? Does approx. 20rwhp more make that much of a difference?

ajag states: With the same blower and pulley the boost increased from 7lbs to ~10lbs because of the larger piping and K&N CAI .
I was able to get a tune with that setup at the 420AWD HP to the wheel range...but I started chasing knock issues at WOT .
Q) Approx. 3 more pounds of boost and you go from 320rwhp to 420rwhp? That's amazing for 3PSI. Or am I reading that wrong?

Thank you
Michael Plummer

With the initial install the oil blowby was causing the filter to get soaking wet with oil..also causing it to foul the plugs ...and you couldn't "feel" the misfires or knock really unless you were WOT for a long period of time..but it was throwing codes and my tuner could see the knocks and misfires ...we eventually got it solved by doing the pcv and catch can...plus I had a leaky oring on injector 4


the "stock" srt only puts down ~370 WHP ...so at 320 I could hang with any stock SRT...I would lose ...but not by much. Have you actually ever raced an SRT with your jeep from a dead start? That's what I am referring to...on the roll...the SRT walks away pretty bad...but from a dead stop 0-80 ish the srt would only have about a 3-4 car lead ...I've raced plenty of 5.7L modified jeeps and they were surprised at how fast this v6 was on 7lbs

the stage 2 does increase the boost from ~7lbs to 10lbs ...but the 3lb Gain isn't really where the extra 100Hp was coming from...it's a combination of a lot of factors:

the Stage 1 only had I believe 540cc injectors?(can't remember) and the stage 2 uses ~900Cc injectors- SO you can push A LOT more fuel..on stage 1 the injectors run out of steam ...stage 2 injectors allow for plenty of fuel

Also ...Stage 2 uses the HUGE SRT stage 2 intercooler ...which lowers the temps SOO much that it allows you to tune in a LOT more timing...at the 420 AWD HP(dyno tuned on a new Mustang AWD dyno) mark we still dialed back the timing a bit because I was running out of fuel after 400ish HP...(hence me chasing knock issues) ..so I installed an SRT pump along with a fuel pump booster kit..so now I have plenty of fuel...but blew my motor before we could retune it on the dyno.

this is what I installed on top of the SRT fuel system in my jeep

http://www.jegs.com/i/JMS/227/P2020PPS13/10002/-1


the 5.7 you have is said to be a bit slower in comparison to the 3.6 due to the gearing of the tranny...at least that's what I heard? RIPP has done plenty of testing on the 3.6L and they will tell you the same thing I am saying..that the SC 3.6 will hang with any stock SRT..the gearing of the 3.6l Tranny seems to be ideal for this supercharged setup..


I live in MASS as well Michael so if you'd like to be there when I get this next engine tuned come on over ...so you can see the hp #'s for yourself since you seem so skeptical ...the guy I acquired this stage 2 from had it dialed in at 408AWD HP with the stock fuel system as well...and he pulled lots of timing out of it because he didn't want to have to install a larger fuel system.

Michael....have you ever tested the actual 0-60 of your jeep?

I bought a new track timer and played with it for a couple weeks...and was able to get a consistent 0-60 of 4.6 on the stage 1 ..with some "practice"

I found that I needed to launch at ~2500rpms and then let off the pedal slightly between shifts...this netted a faster 0-60 as compared to just "MASHING" the pedal...this 4.8 sec reflects just mashing the pedal

this is from one of my earlier 0-60 passes

Re: Thinking about an SuperCharger...

Again, there is no skepticism on my part. If I don't understand something I ask questions.

Not sure what Jeep SRT you're talking about but I thought they made 475HP and not 375HP. And yes, I have raced a stk. Jeep SRT from a stop, a roll and the race is basically over once it begins with me losing. So please explain how 320rwhp comes close to 400+rwhp.

You never mentioned adding more advance to your tune. The way it's written, sounds like you add 3psi and got 100rwhp. Normally, when we add more boost we remove some advance but everyone is different. But I'm curious how much advance was added.

You mention the following, "which lowers the temps SOO much that it allows you to tune in a LOT more timing" which is true it gives you a broader tuning curve but in the next sentence you mention "we still dialed back the timing a bit. So how much advance or total timing did you have to make 420rwhp?

Thanks
Michael Plummer

That's 375 wheel horsepower. That 475 is advertised at the crank. They never give you wheel numbers. Even that 375 is high. I've seen plenty of SRT jeeps do only 340 because the awd system takes more of the power away
