Is there any concern adding 100 extra ponies to the 3.8 liter. Will the 3.8 motor hold up to this much additional power? I am very interested in adding a supercharger to my Unlimited but I am a little worried about the engine holding up. I know that if I hammer on it of course it isnt going to last, but if you take it easy and use it when you need it would it be ok. I really like the way that my jeep works when I am off road but when I am on the highway it is really bad about pulliing the hills. The altitude gets me a little. I really like the idea of the Hemi I just cant afford to do it.

 

I think it would hold up if you do not hammer it. And if you hammer it alot you will probably break things. If not the engine, then tranny, dirveshafts, axle shafts, suspension brackets, etc.

As you surely will break things hammering an extra 145 HP with a 5.7 or doubling a jeeps HP with a 6.1.

My point is, I found that vehicles always have a weak link. Adding horsepower can help find those weak links There is a good chance the lower internals of the 3.8 is not the weakest link of a 300 HP JK. The auto tranny would be in my opinion.

I probably moved my "weakest link" to the drive shafts and/or axle shafts. I am sure I will find out. Because while I behave most of the time, I am too young at a mere 51 years old to stay out of the pedal all of the time. If you truly can I salute you.

I think the key would be to make sure your cruising RPM range is in the "sweet spot" where the supercharger is adding decent power. Especially with an auto tranny. So it seems to me gearing would be important. I think pulley size for the supercharger could have effect also as it would control boost by controlling how fast the SC spins. Heck maybe the computer does that now, I am old school on that stuff.

A V-8 would also operate more efficiently in the proper RPM range of course, but is a more forgiving because, well, its a V-8!

More knowledgable people will chime in, but I would not hesistate. Life is too short. If you can afford it, make your Jeep your own, so you love every minute of driving it!

 

If your primarily after more power on the road, I think the supercharger route would be fine. The only thing I wonder about is the long term durability of the 3.8 under boost. Can you really keep your foot out of it? Either way the SC or hemi comes with risk of breaking things with no warrenty to back you up.

For most the people who participate in the Xtreme and Modified forums, I bet Wranglers are not just transportation, but also a primary source of entertainment (recreation?). No different than boating, racing, etc. All expensive and all fraught with costs, because we will break stuff and/or get bored and mod stuff. Otherwise, we would all be driving some econo-box car and staying home to watch TV.

So it all boils down to what you can afford or how patient you are to save for something.

Because, surely, no one here is going to tell me owning a Wrangler is....practical[/QUOTE]


Practicality; you know I thought a lot about this when I bought my 2011 2dr JK and I still haven't come to a conclusion yet as it only has 1600km on it. I live in northern Canada where, snow is on the ground 5 months out of the year(might be exaggerating!) So every year I take a month off work and travel around the US typically putting about 10000 KM highway on. So you can imagine this came into consideration. I've always wanted a Jeep just cause of the fact in the summer you can bomb around with the top and doors off. But Im starting to wonder if it was a real "practical" decision!! I've heard jeeps are sketchy in the winter, and I already know highway travel is not the best! I don't go offroad a whole lot but when I do its not rock climbing or mud bogging!

So what im wondering is what the longevity of the 3.8 putting a RIPP kit on my jeep be. Totally not even considering a hemi conversion because I think thats just overkill. But to me a SC is a major upgrade and I want to be sure that given the amount of travel I do, and the weather conditions up here that a SC kit would be ideal or not.

 

Hi there , I used to won a 2008 2dr jeep jk sport auto and transformed it to the ultimate machine, I did a 6.1 hemi swap , auto transmission , 3.5" rancho LT lift kit, 35" tires, 4.88 gears front and rear, steel front and rear bumpers, , my regret is I have should've done this on a 4dr. The 2dr ended up with so much power I don't need but good to know it's there under your foot. Max power came out was I guess over 450hp , in the desert sand u have to easily tap on the throttle coz of the quick response and wheels turning and ending up stuck, also there was an issue with the 3rd gear which is a common issue with srt itself the torque tends to reduce then catch up which is annoying , other than that I was on the road head to head with Porsche cayennes , BMW x5 u name it and the sound was awesome. But eventually I sold it .

 

Dudes, A few months back on Spike T.V. the show Trucks, or Horsepower did a dyno/cost comparison of both. They said the Ripp supercharger was the best bang and horsepower for the buck. See if you can find the episode and check it out.

 

Yea what he said I saw it too. It was great.

 

We have clients on this Forum who have driven over 75000 miles on our system - Our kits are rather reserved and really don't look to blow things up. Jeep guys are not Vette guys - Meaning you aren't looking to go foot tot he floor and light to light racing. The RIPP kits perfect for transforming your 108WHP (on 35's) to a 200+ rear wheel HP vehicle, making it easy to drive...

With nearly 1000 kits sold world wide - we would say its proven its worth...

2011's? Pretty Please?

 

Ripp would be nice to get. Is the 2011 tune worked out yet?

 

Sick video RIPP. I am looking to get one of these after my prorock 44.
