Horse power numbers are great but do you have any quarter mile proof? I know our jeeps are not hot rods but a true performance increase is found in 0-60, quarter mile, and top speed runs.

None the less I WANT ONE!

 

....and to add more fuel to the fire...LMAO......I'm also concerned about auto and manual transmission problems, clutch grenades and engine overheating problems. These are all problem areas the Jeeps seem to have STOCK, much less with a blower. Again, not trying to rain on the blower parade.....if these concerns have been dealt with, please tell us how. I mean these automatic transmissions seem to be screwin up on a sneeze. The clutches are noisey and give problems from what I've read on here, and the cooling systems seem inadequate in some cases. I agree too that the 0-60, quarter and top speed numbers would be a good indicator. Hay, and you never answered that 100,000 mile warranty question, either. LMAO.

 

For RIPPMODS and REDNECK JEEP

Hey guys I really appreciate the conversation you've been having. It has stayed respectful and you've both put out good information and valid concerns.

This is a subject many of us, without both of your techical and practical backgrounds, are concerned with. Most of us feel (even those of us with 5.13's) that the JK needs more power. I had figured that I'd keep this one until the factory came out with something better. But I've got so much invested in this that my wife would want to shoot me. And the hoped for diesel may not be the answer due to the high cost of diesel (I had to pay 5.60/gal to fuel my work truck the other day).

A Hemi would be nice but 16K+ isn't in the cards. If the AEV kit is around 5k the total cost would depend on the cost of an engine and trans and whether you did the work yourself. The total cost would probably be from a low of 8-9k to a high of 10-12k. And I haven't heard any input from the Hemi owners as to gas milage etc.

So an SC in the mid 4k range, that we can install ourselves, may be the best answer. It would sure beat the hit we'd take on trading in, or selling, our current JK and buying new.

For RIPPMODS
One of the things I notice is lacking in lots of info on performance enhancing mods is legit real world numbers. Why don't you buck this trend and give good solid numbers.

Take a stock Jeep with 5000 miles, so its broken in, and run various tests on it. I'm thinking in terms of 0-30, 0-60, 0-75, rolling tests such as 30-60, 40-60 and a test simulating passing a slow truck like 40-80. A 1/4 mile drag strip run would be good too. And then do them all again but with the max wt of trailer the factory sanctions for the Jeep. Run some fuel consumption loops of sufficent duration to be meaningful including freeway and in town. Then install your SC and do it again. Then post the numbers. It goes without saying that the tests above would have to be done in an auto equipped Jeep so as to eliminate as much driver influence as possible. Maybe you could contract with folks that do tests like this all the time for their magazines; like Car and Driver or Road and Track.

One other thing; you have mentioned before that tires and gears effect the outcome of dyno tests. I revise my request above that the test mule be stock. The ONLY guy that is going to drop 5k into a blower is the guy who has already modidfied the Jeep. Test a lifted Jeep with 35" tires. If I really had my druthers the test would involve one with 4.10's and then 5.13's. And that wouldn't be that hard to do. Swapping the front and rear axles out is no big deal in a shop.

Thats what I'd like to see from you and the other SC manufacturers before I drop my dollars. How about it. 5K isn't 16K plus like a Hemi but it is a lot of money.

 

Well said Chuck.

I'd be very interested in a blower, got the cash right now, especially if it gains me $1500 from not having to re-gear the Rubicon axles (running 35" Toyos with zero complaints aired down offroad in 4-lo) and delivers a significant gas mileage gain over the 14.5MPG I'm getting right now in mixed driving.

It seems 4.88 (effectively the same as 5th with 4.10 gears) still doesn't give me the power I would want for hills at highway speed (Max Energy with premium fuel), and 5.13 with the 6-speed might be the best option but would place the RPMs pretty high at 75-80mph on the interstate.

So, how does a 2 door with 35s, 4.10s, bumpers, winch, armor, the driver and 2 passengers, recovery gear and tools in the back, pull from 60mph in 6th up a slight grade?

 

Hey RIPP When you and Red Neck stop arguing LOL can you hit me with a PM. I wanna start my project in DEC and I am looking for an ECU. Also we may have something else to talk about in this arena.
I did my math and am puting in the Greddy Turbo. mainly because I wanted the 1700ish Boost start. and my buddy had one laying about LOL
ANYWAY. @5K it seems as though this lil 3.8 will be somewhere in the 335.64-234.94 VFR @8PSI are you seeing that?? that is 100%VE and 70%VE
Thanks
Doc

 

HUH? You're way over my head!

 

Just some #s I came up with doing the math to figure out what size TC I wanted to put on my JK. Big A$$ed math problem but at the end of the day I figured BY MATH that the greddy TC my buddy had would work on my 3.8L/232ci put out approx 260 whp @5K @8psi of boost. AGAIN this is math and fuel propigation and parasitic drag cannot be factored in (YET) we are working on the Timing/propigation piece

 

I am not trying to be cryptic or secret It is just that my project is the last one on our (me and a couple Diver buddies) table unfortunately the rice burnes get the first priority and the 4X4'ers get last so... BUT in DEC I will be doing the remote TC and tuning with our software I will start a thread and post results there. I will Dyno my JK, then run the SW, then dyno again, then add the TC, Dyno, run SW, then dyno. so we will have a good set of #'s to look at.

 

Very interesting. How do you think that a turbo will perform relative to a supercharger. My understanding was that turbo's were better for high RPM, high HP applications and that power was delayed a bit since they needed to spool up. I also understood that SC were better for torque since they were belt driven and provided boost down low.

On the other hand all of our semi's are turbo'd Cats and Cummins and they live in the 1700-2100 rpm range. Our big 2300 HP V12's are blown and turbo'd.

 

Guys I really wish you could seriously talk to the RIPP guys in person....I kid you not.....trying to explain everything via the net is so damn difficult....I was at their booth for nearly 3 hrs (PA Jeep Show)watching, listening and learning....and what I found out was amazing and why they do the blower this way rather then another way. It just comes down to understanding...and from talking to Perry and Ross....they DO understand. I am convinced of that 100%. No talking me out of it.

I think they ARE going to teach the old dogs new tricks...and i truly hope the old dogs learn and at the same time pass on information so both groups learn something. EVERYONE benefits here...


Anyway...moving forward....

RIPP Motorsports I think has it all figured out. I guess thats why some other high mighty aftermarket companies are calling them and asking..."umm...how...."
