the pentastar with an aftermarket intake and NO supercharger sounds mean. I'll see about getting one installed
THIS VIDEO IS SOUND OF AN INTAKE NO SUPERCHARGER> JUST MAKING A POINT.
http://youtu.be/p2f4Uh6aE1U
Driveability is spot on. You wouldn't know the truck was supercharged if you didn't know jeeps and got behind the wheel. You would just think it was powerful. The power dosent come on all at once, like a lot of aftermarket power mods. You would just think jeeps were fast. The power is steady across the rpm band.
stop and go traffic? no different than any pentastar, but the gas pedal feels lighter and the power plant is always more "ready" with power if you brush against the gas pedal.
Remember this is a stock Rubi outside of the SC so we aren't making it turn huge tires, or steel bumpers or any of that stuff. Sweet pea will get built up this year but for right now we were looking for the max power without weighing her down.
One issue is some power surging at cruising speeds on the highway, Im sure it will get sorted in the next tune.
Hemi still worth the money?
Either supercharger will smoke a hemi. My position is that there is NO point in tearing your engine out for a hemi. If you followed my threads, there was a thread that I opened about a year about challenging anyone with a hemi to line up with Black Betty. I watched the thread and cultivated it for months.
There were no takers, And im not in kansas somewhere, I can see NYC out my window. The most money in the country is in this area, so there are hemi's here. Did anyone want to tangle with Betty? NOPE.
I made the offer publicly. And would have taped the race had I been able to get an opponent. Couldnt have put my money on the table more.
As far as RIPP vs. Magnuson directly, The head to head is coming.
I wanted to give the Magnuson info out to catch up with the work we did with RIPP's unit last year.
Once the same tests are done, we will line them up and test head to head.
Here's how it went.
My dyno is first. We had some issues with the air in the shop, the guy was running it without a fan. Pete, one of my guys, and the owner of the truck had to turn the fan on in the place.
Here are my numbers and Magnuson's.
They are on two different dyno machines, in different locations, and Im feeling like I might want to get another shot at the dyno with sweet pea.
Sweet Pea's First dyno

Here is Magnuson's own chart.

Magnuson Pentastar Dyno with "Engine Speed"
Attachment 212
Here is the dyno chart with the original dyno on the same page.
Here's what you have to understand. In 4th gear, when we started, the truck had a speed limiter that we hit around 5500 rpm. Thats why the band is shorter.
In 3rd gear we got around 220 hp. keeping away from the speed limiter.
4th gear is more the 1 to 1 with the stock tires, and without the limiter you can see the results. I only mention it, because I think the pentastar makes about 225 "uncorrected" which makes sense and agrees with black betty's stock dyno last year.
So this is the chart of both 4th gear pulls, but the lower one is short because of the speed limiter in the JK that was removed with the magnuson tune. (thus we don't hit it after)
Even tho we didn't get the same numbers magnuson got, that torque curve is pretty sexy.
Stock vs. Supercharged Dyno Chart
Attachment 213
There was a fan on when this pull happened. The guy doing the dyno didn't start working with the fan on. The point i was trying to make was maybe this wasn't the most professional set up. But in NJ its hard to find a dyno, we drove 50 min to get to this one.
That 4th gear dyno is cut short by the speed limiter. I think the pentastar makes about 220 whp. UNCORRECTED. I think you can expect more like 65 whp increase from stock with my numbers.
The magunson dyno shows a better power gain.
Is it because my numbers are the 4th pull of the day? Poor ventilation?
I don't know. but for reference I wanted to give you guys what I got.
I think another dyno will tell the tale. Im going to get there early and keep it cold, then make it sing.
Better air flow and a cold SC is the way to get the best numbers, but that takes the real world testing and puts it in a test tube which is not my intention.
Betty's dyno won't happen for at least 10 days, as i have to wait for Super Bowl sunday to pass, its a mad house in this area right now.
I sent magnuson my air flow files and they told me that the flow is off or the unit reading the flow is off. So I'm going to let them look it over and if they send a new tune between now and the next dyno i may have new info.
If the new numbers are significantly different we will know its the shop i used, as the weak link in the chain.
Sweet pea's gettin new oil before dyno
Attachment 214
This is the magnuson oil filter, its 2 pieces because with the blower on the engine, you cannot get a standard oil filter in and out.
2nd dyno chart for magnuson
Attachment 289
Now, about the chart I posted,
Magnuson told me to bring it to 6100 rpm. We took it to 6500.
Here's what I want you to see.... there is no "crest".
The power line keeps going, What that says is that this unit has more firepower than this dyno is showing. The mechanics wanted us to take it to 7k, but I wouldnt let them with the truck not belonging to me.
Pete was standing right there, and seemed like he wasnt against taking it further, but had something gone wrong i wouldnt have forgiven myself.
He LOVES his jeep more than anyone I know, and Im a guy who LOVES his Jeep.
No one here is taking their truck past 6500 regardless.
What I like -
That torque curve is very strong, and its consistant, when you check the prior dyno, its the same line.
What I dont like -
Anyone who buys this unit should consider an intake, Im going to put on on Sweet Pea, because I think the stock intake is -
1. air constrictive.
2. kills the sound that pentastar makes.
Right now Sweet Pea sounds far more "polite" than betty, but would she scream with the intake on? Get the plastic cover off her mouth. I'm pretty sure the difference would be night vs. day.
Ill get one on and sound bite it.
Then the question will be....what does she dyno at with the intake's less restrictive air flow?.......
I am expecting an intake and exhaust to make a drastic difference in sound. To the layperson, I'm not sure you would even here the supercharger.
Agreed on both accounts.
I think an intake will change the sound significantly.
I only use my rubi as a off road or towing rig, the ripp jku sport is the dd. Gears will be done at the same time as sc install. Stock 4.10s now. It's a heavy jku with fab fours(ff)front lifestyle full bumperw/ grill guard, winch, ff rear bumper and tire carrier, and ff rocker guards, interior is linexed. Metal flares in near future. Hard top. And I have a 10ft high side trailer that I load with ranked wood, and have to cross three steep graded/ low speed mountains to get from my land to my house. No interstate ever.

......yeah, that didn't work
Were you linking? or uploading the photos?
Was attempting to upload
I'll be the 6spd with 5.13s really creeps in 4 lo 1st gear.
It must almost seem like its not moving. Thats what you want when your rock crawling. Nothing wrong with MORE GEAR.
Did we ever get an intake on this SC?
no way I could afford it, but I'd love to hear it.
Funny,
I have a truck (Tonka) that I want to take the intake off, AFE proguard 7,
And I cannot get Tonka and Sweet Pea in the same place at the same time to do it.
It will happen eventually.
I have a 2014 Rubi and stock everything except for the 4'5 lift and 37's. My question is on the transfer case, drive shaft and differentials. There will be additional stress on those things because of higher torque. But I am wondering on how long the stock items will last?
^^ Thats a tough one. The problem is, that there is no magnuson or ripp or prodigy turbo rig that is more than 3 years old right now. Are the parts you mentioned getting beat up? Maybe. No one can really tell until one breaks and we can see, 55k miles, 2012, and the transfer case went.
Also, how hard are the parts wheeled? Normally breaking stuff off road is when you hit the throttle with a tire bound up or goosing the throttle and the tires slide and then grab. In any of those cases your not going to blame the power mod. That would be on the driver.
Now that being said. If you had a supercharged babied mall crawler, and one of those big ticket parts was to go earlier than normal, THEN i'd blame the power mod.
We are going to have to wait and see. I think the bottom line is, if you are smart with your jeep, and change the fluids and wheel responsibly, I doubt the extra power would hurt the components your talking about.
Thank for the reply. I do trails that are green to black. I stay off the red since it's mostly mountains and mountains of rocks at Rausch Creek Off Road park. From the sounds of it that it will not break right away (Knock on wood) after I super charge it.
Another quick question. Is the premium gas a requirement after the SC? or can I still use the regular. I know I will not get the maximum performance. I am more worry about the adverse affect. As to if it will hurt the engine/SC.
Probably the best place to look for your answer is with people who have done the V8 swap years ago. The SC's and Turbo's are too new to even have enough data to know how the stock parts will hold up. The V8 swap guys have been doing that for years now, so they would have the most real-world data on how much added torque the stock parts can handle.
For the differentials, at least you know the specs of a Dana 44, etc. and those are often used in the application of a V8. For the drive shaft, well, it is busts, damn, it busts, and you buy a new one. I wouldn't be surprised if there is lots of information out there on the transfer case and what other vehicles are using the same transfer case that potentially have a higher torque engine in them? I know *nothing* about the t-case, but, did it come from Mercedes? Is it used in the Grand Cherokee as well? Maybe a Durango? If so, then you'll probably have your answer that it can handle more torque just fine.
