I know guys that have been using the same vortec blower fit 10 years with only a few rebuilds.

I "think" you can but only with the hemi swap

Oh ok. .glad to see I was wrong

what would it cost to get the tj nsg front case in the kit? And how much would it move the trans mounts? Is there any firewall clearance issues with the larger tj bellhousing?
 
I just went to turnkeyjeep.com, and they charge an EXTRA $1000 for you to keep YOUR old engine and trans. WTF?

Believe me, i would put a GM v8 in my jk long befor a supercharger, but i sure as hell am not paying somebody $1000 to retain something i already own.
 
So, to summarize this thread:

A RIPP stage 2 costs $5300 and takes a "weekend mechanic" about 7-8 hours to install. A professional mechanic could do it in about 5-6 hours--$500-$600 labor.

The RIPPd 3.8L produces approximately 90% of the horsepower and torque of a 5.7 Hemi and weighs less. So, actual performance net of the weight differential is fairly close.

For those who want extra power from the RIPP, they can run a high altitude pulley--or order it with the smaller pulley at time of purchase. They can also run a more aggressive tune.

For those who want more power, they can do exhaust modifications--either relatively inexpensive short tube headers or $1600 long tube headers, plus a different muffler.

If the owner does not do good maintenance on the Vortec blower, and the bearings or seals need refreshed, they can send it to Vortec to fix at a relatively nominal cost.

When, the owner decides to sell their JK, they can pull off the RIPP and sell it used and recoup 2/3 of the cost of new.

So, basic net cost is $5300 for the self installer, and $3500 is recouped when the jeep is sold.

Net cost of running the RIPP is about $1800 for the self installer who buys new and sells used.

Add about $1000-$1200 for the person who pays labor for the install and uninstall. So, $2800-$3000 total net cost for the person who pays labor.


The downsides to the RIPP:

It doesn't get rid of the 42RLE automatic transmission.

The JK cruise control does not react fast enough to changes in speed/power. So, at freeway speeds, in windy conditions, the owner experiences a slight surging feeling when the cruise control is active.

If you offroad or go with larger tires, you need to regear your axles (costs about $1000-$1500 parts and labor to regear a pair of JK axles).



Installing an LS or Hemi:

Install kit is about $5,000-$6,000.

Used engine and tranny in good condition might run $5000-$6000.

Crate engine and tranny is $13,000-$16,000.

Install time is 40-50 hours--$5000 if professionally installed.

Driveshafts? Depends.

You can sell your stock 3.8L and tranny for about $2000 to offset the cost.

Total initial net cost for a DIYer capable of the install: $8,000-$10,000 with a used engine and tranny, or $16,000-$20,000 for a crate engine and tranny.

When the JK is sold used in the future, the V8 will probably increase the value of the jeep by about $3,000 to $4,000 for a 5.3L, more for an LS3.

Total net cost for the DIYer when jeep is sold: about $5,000 to $15,000+ (compared to $1,800 for the DIY RIPP owner).

Add $5000 in labor to the above costs for the non-DIYer. So, $21,000-$25,000 net cost for a crate engine and tranny, or net cost $13,000-$15,000 for a used engine and tranny. Net total cost when the jeep is sold in the future, $10,000+.


Other advantages of the V8:

More power, no need for premium fuel with a tune that isn't aggressive, sounds awesome, LS engines have great longevity, sounds great, unique. An LS will get similar fuel economy to a RIPPd 3.8L.

Jeeps that don't rock crawl or run larger than 35" tires may be able to get away without spending $1000-$1500 to regear axles.

No more 42RLE transmission.



Summary

In the end, how many people who are in the market to spend $5300 vs. the cost of the V8 conversion up front?

How many people are fine with an $1800 net cost when they sell their jeep vs. the net cost of the V8 when they sell their jeep?

Obviously, there are many who have the money and/or skills and time to do the V8, but the market isn't as big.
 
The JK cruise control does not react fast enough to changes in speed/power. So, at freeway speeds, in windy conditions, the owner experiences a slight surging feeling when the cruise control is active.
FYI: RPMExtreme can fine tune the RIPP SC tune to "virtually" eliminate the cruise control surge issue. Just ask RockyClymer, he has the RPMExtreme tune.
 
i have a RIPP supercharger and have used them on a few jeeps and have always been very happy..great customer service... installed them myself ..gave me the kick i was looking for :beer:
 
Planman,
I get the impression that you think because a supercharged V6 has 90% of the horsepower of a V8, that it must have 90% of the "performance" that a V8 has. I've owned a supercharged V6 before. Have you owned a JK with a V8? I'm just wondering, because as far as I'm concerned the performance of a V8 is far better than a supercharged V6. A supercharged V6 feels like a fast V6. A V8 is totally different, and in a whole other league. At least my 6.4 feels that way to me. It takes "performance" to a new level.

Robbie started this thread with a comment about an advertisement for a supercharger that said it was nearly the same as a V8, and stated that he thought that was a bit of a stretch. I agree with Robbie on this one.

I agree. The torque and horsepower curves on a V8 are very different than a supercharged V6.

And, the net cost is correspondingly different.

With the right differential gearing, fuel economy, 0-60 times, etc., the supercharged 3.8L performs similarly to a 5.7L Hemi or a 5.3L.

I've owned 2 5.3L GMC 1/2 ton trucks and a 5.7L 04 GTO. My present truck is a 6.7L Cummins 12 Ram 3500 Laramie that has been deleted and runs a MiniMaxx Wild tune. V8s and big I6s are awesome.

It's all about budget and priorities. Are the torque and horsepower curve differences worth 3-5x more in cost?

I would love an LS3 swap. However, I could buy this for the cost of doing an LS3 upgrade in one of our JKs:

Reading this thread it's like the RIPP is the iphone. No matter what you say is the best.

RIPP is a great product. I almost bought one until my wife said wait a year and we'll get the ls. The price of RIPP w/intercooler is nearly half the cost of the swapp. Factor in the sale of your old powertrain.. it gets very attractive and affordable. There are low mileage ls engine/transmissions all over Dallas for $2500.

No brainer for me.

If you can do the install without paying $5000 for labor, you can find a solid LS and tranny for $2500, you can sell your takeout for $2000, and buy the install kit for $5000, that would be a no brainer.

Wish my RIPP'd jk ran as advertised. Still chasing mechanical demons.
Which totally makes me want the LS swap.
But I digress...

my autoguide app has a mind of its own
