As promised, here is the 2014 we currently have on the dyno. We made around 525 horsepower before we had to address another project so there is more to come. A real basic file in this thing at this point but progress none the less! Stay tuned for more information! BTW, this car is being tuned with our MyCal unit.

In for numbers/progress. How is the heat affecting the 6.4s? Everything I have read is that the Head-Unit type have less heat than that of the Whipple/Roots blowers.

I like this look better honestly, and the instant torque would be awesome.

Thank you!

Well its tough to say really. Will we offer email tuning? Yes but typically we like to stick with tried and true combos that we sell or that we have done. If you have, for instance, this supercharger kit with a few subtle differences, maybe a different catback or longtubes or something of that nature, yes we can handle it. Eventually we WILL offer packages that will make things very very easy for everyone. If we are unsure, hit me up before you purchase anything I will make sure I give you a definitive answer.

What boost are u running? And how do u feel about it on the stock internals?

And is that torque considered a safe level for the 8 speed trannies?

The whipple kit looks pretty sweet, I promised myself I wouldn't go down the boosted path but dammmmnnn... It's so tempting

This particular jeep hit between 6-7psi. Stock internals seem to be doing just fine, no real issues there that we can see but honestly time tells all. The 8 speed seems to be taking it like a champ as well. Now it terms of tuning a Dodge/Jeep/Chrysler, we find that particular applications, especially high hp ones, we can leave tq management in on the shifts to take some stress of the transmissions as well so that is an option as well. Spark reductions usually work just fine as airflow reductions often become noticeable to the driver.

News :: Whipple releases 12-14 Jeep Cherokee SRT 6.4L Supercharger kit! - Whipple Superchargers

Is this the kit you have installed, and are your power figures at all four corners, or just the rear?

Why do you not utilise the SCT tuner that whipple supply with their kit?

Just trying to get my head around it all lol.
Sorry I almost missed this question.

Our in house software just simply has access to a ton of other parameters simply not there in the SCT or Diablosport software. Sometimes the parameters are simply, others are very important and cause the car/truck (when not changed) to act strange or not make the power it should. Case in point on these newer Jeeps, everyone said with a Diablosport tune that they were slower then stock. We figured it out in our software and now offer tuning for NA applications that is very solid. I posted that graph/jeep in another thread.

Those numbers were achieved on our AWD dyno, so all four corners :)

I'm a lil late on this nice to see Livernois over here doing it BIG with the Whipple!!!

You can trust these guys People they are the real deal with a great reputation in a lot of platforms. I'm glad to see they jumped on board with the Jeep we are really luck to have a shop like them here with us!!!

Welcome to Jeep Garage Don Nice work!!!:thumbsup:

Ripp needs to hurry up. If I could choose between the two options, I would go Whipple now. I don't know if the Ripp boys would let me cancel. Maybe I can squeeze another lb or two out of their kit to get me to 600AWHP.

Been on order for 3 weeks come monday. Still hadn't shipped.

Is there any data on the flow rate of the whipple front inlet and the throttle body? Seems like the throttle body would be a restriction at some point being so small for a twin screw setup on a big engine.

Does anybody have a quick "why is a whipple" better story for these hemi's... I just think if Chrysler used this type of set up for their new challengers and they did all that r&d on motor wear and tear then I would feel more comfortable with this setup.

Is your programming more reliable than Diablo. More effective?

Also Don me living in Australia is this kit a complete bolt on do it yourself kit ? Or I need a mechanic and a dyno after the install , sorry for the noob questions mate but I never put a SC on a car before let alone try and tune one . Any help in this would help which way to go in the SC decisions .

The only mods I have done is the GTHaus Exhaust which I will put on next week hopefully , thanks for any input .

Unfortunately gentlemen, Livernois and I have parted ways at this time. I will do my best to help you guys out with any tuning related questions (as I am a previous employee of Diablosport as well and have my own CMR software all GM, Ford and Dodge). However, at this time I won't be pushing products for Livernois.

That being said, the install isn't bad, you could handle it yourself.

bummer! I would be seriously surprised however if stock internals can handle the 200hp increase with no longevity problems. I know it's an issue in the german market when pushing NA to FI. Especially concerning the Mercedes AMG 5.5l. They supercharge it on some vehicle applications (E55/CLS55/S55/SL55) and with those vehicles they have upgraded internals to handle the increase in power and maintain longevity. Plus that OEM SC doesn't add 200 hp either!

First of all I wanted to take the time to let you know that we, as Livernois Motorsports, will be continuing on with the support for this board. This is a great platform, and one we definitely have some big plans for it moving forward.

With the proper tuning, these engines definitely can handle this type of power increase. The issue to date with the 6.4 engines has always been in our opinion tuning related more than anything else. We have spent time completely re-engineering the way the computer functions in these applications to ensure a reliable setup for years down the road.

We have some applications (namely the 6.1, and 5.7) that we have added well over 200 on the stock engine and the cars have been flawless for years. With that being said, there definitely is a point where we would recommend upgrading the internals. We have our own, proprietary internals, and engine upgrades that we do for the entire family of HEMI engines. From rotating assemblies, to cylinder heads, to rocker system upgrades, camshafts, and more.

Shoot us a PM, or respond here with any questions you may have!

The truck came into our facility already outfitted with headers, exhaust, and a cold air intake (along with a tune from another source). The Baseline run on the dyno was with those modifications already installed, so this is a true "delta" from just the supercharger and our tuning. We have a few already set to come in that are going to use stock exhaust to keep it a little more tame, that will give you an exact gain on a bone stock vehicle, but we expect the results to be similar.

edit:

We are still working on drivability calibrations now. We get everything handled on the WOT, and have been working on the drivability portions. We expect to have this 100% completed soon. After that is done, it is heading back to Texas for the customer to make some passes with.
