Ripp supercharger questions
Heck i even asked why Vortech over Procharger....main reasoning? Packaging...the Prochargers are a lot bigger and the Vortech unit spec'd out exactly the intent of what they were trying to accomplish. And in my eyes they accomplished it well....However who knows...maybe in the future they will put a Procharger on it. But right now, that Vortech sounds/looks awesome in the engine bay they even mentioned that at 1700rpm about the dead air space etc the 3.8 has....And the thing revs like you wouldn't believe, .wow..but when he reved that thing?...My eyes were bigger then golf balls....I smiled at Perry and said ...."Yeah you did it right!" I got a humble...."I'd like to think I hit it out of the ballpark." And that I think he did. Granted its not a Small block per se' but dang.....for everyday use I think this is the hot ticket....
Not going to lie to you. I was apprehensive too...but I literally watched them and hung out while doing the install and got educated in the process....I learned a lot on Saturday and I am looking forward to being able to install one myself...

THANK YOU!!
I like the RIPP if I did not already have the Greddy and the plans I would prob get one. it looks like a nice tight pkg all inclusive decent price. TC/SC's have been prooved for many years now, there are a butt load more TC's in Europe on all sorts of cars, LT's SUV's than in the States. I cannot wait to start my project and show the #'s. Not to endorse or put down any one way or brand but to proove the ability of the 1Gal engine to be Forced.
....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.
We don’t run any hotter than stock at any time even when idling of wheeling.
We aren’t the dealer, we don’t speak for them… but I’m certain that if you show up with a blower they will frown upon it. When we went to our dealers they didn’t… but they are cool about things like that. They were cool after they scanned the ECU and found it to be completely clear of codes as well…. So that’s as much as I can elaborate on that… I said the same thing in the other post you mentioned this as well.
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

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.
I’m sorry but we really can’t elaborate on any of the VE calculated or true, as we keep that information on the DL. Our programming will work for you if you’re interested in using it however it will require you to adapt to our technique of supplemental injection.
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.

Remote turbo’s leave a bit to be desired form the VE side of life, we tune them often on daily drivers… all in all they are fun but I’m not sure how practical it could be off road or mudding. Turbo’s and the piping generally don’t like to be cooled at all and we find that the tune constantly needs trimming even on rainy days… but if your willing to tackle it you should… Often remote turbo guys will run around with a lap top plugged in or a hand held fuel controller to give it a tweak here and there. Or have multiple maps until they find the happy medium.
The principles of turbos are built around exhaust and more importantly heat... so there are factors there that need addressing and even though you got a free turbo it doesn't mean that "it" will be the one you end up using...Greddy turbo's are laggy to begin with..I would use a dual ball bearing as a start point.
- Our perspective – from a performance tuners consulting perspective is: the SC is an easy solution to an ongoing problem… its in the box its easy to use, if something goes wrong you won’t be stuck and you can run 87-93octane…if your going to go turbo there is a lot of tuning to be factored in like load per gear waste-gate size intercooler location and size… timing safety parameters should there be an over boost or spike… we as manufactures would not be willing to assume that risk in a box… as an individual Aquadoc can….as he seems to be “calculated” in his steps and well placed with help.
I too hope both sides learn. I am sure since I have been out of the loop, light years of advancements have taken place. .....but imagine, if you will, a 3.8L built with ALL the good stuff I've talked about in all my posts. If the RIPP deal can make a stocker make 107 more rear wheel hp, what the hell could it do with some high strength internals and HIGH boost numbers???? You'd have to upgrade the whole drivetrain to take it........and that would be a good thing. LOL 

LOL
I recall reading an artical in a magazine a few years ago about a very successful builder of Allison V12 engines for airplane racing. Apparently he was quite successful and I expected that he would talk about things like porting and such. But no, he said it basically came down to making everything strong and then cramming as much boost in as you could. If, or when it blew up, you made that stronger and used more boost.
I imagine it would be neat to have a 3.8 built with trick parts to handle a lot of boost but if that was done the cost would probably exceed the Hemi. One could argue that the 3.8 would be lighter, but as heavy as these things are and with all the crap we hang on them I don't think that is a big issue.
If it cost as much to pull, build a stout 3.8 block, install the motor, SC and new tranny as a Hemi would cost why go SC or turbo. It seems that it only makes sense if the cost is half or less then a Hemi conversion.
So maybe it all comes down to money; doesn't it always? Our options may be:
1) Learn to love the stock 3.8 at the cost of 0k
2) Install gears and learn to love the stock 3.8 for 1200-1300
3) Install a SC for 4-5k
4) AEV Hemi kit plus motor and trans for 10k or ?
5) Professsionally installed hemi for 15-25k
Maybe Ripps way is the middle ground. Less power than could be obtained with a purpose built 3.8 but with a reasonable cost and adequate power boost and longevity. Heck, I don't know.

As manufactures we take the added responsibility in trying to be as safe as possible… that’s a lot easier to do with a good supercharger than it is with any turbo.
Lastly… there are a lot of small displacement car in Europe… hence the turbo’s. thats like saying there’s a lot of V8’s in America.

)The kit is nice, after it was all together (this was a customers jeep and he is in Iraq if I recall) they started it up, monitored everything, shut it down and adjusted tubing here and retightened the hoses to give it the absolute best fit and finish.
I will say that Perry and Ross went above and beyond explaining everything to me, and I soaked it all in. Why this, why that...why not this and why not that...and here are the reasons etc...
No, I am not getting paid to say this, no I am not getting anything for this. I am telling it like it is. The funny thing is last year when RIPP was at the PA Jeep Show I mentioned to Perry that I talked to a really nice guy explaining the kit to me, Perry said..thats Ross he is right there...and a friendship started up. (at least i think it did. hahaha)
Regardless, both Perry and Ross drive JK's. Perry has the prototype everything on his JK and Ross has the production version.
By the way...the installation manual? Its all color, step by step photographs...templates...very well thought out with the enthusiasts in mind that will install the kits themselves (ie. Me)
Yes being "calculated" meaning I have done a lot of math. The math puts me in the ballpark, an educated Guess as it is. I do not have 20~ years of experience like the RIPP guys do (wish I did) as it is kinda scary doing this to my daily driver
. BUT I have confidence in my team and While in the desert we did take two carbed, 90 Toyoto Land cruisers from the "Junkyard" (DRMO) and mate a VOLVO turbo to one and all was great. The math said the Turbo was too big but we found that the "LAG" was almost nil. And again if it were not for the fact I already have a plan AND am going for my own end result I would seriously consider the RIPP SC. I am gonna have a laptop strapped in, and software and all that jazz. My mount will be a "mid mount" right behind the headers so lag and cooling SHOULD be just right. We'll see.

I have driven the RIPP jeep. It is awesome!!! It truly felt like a larger displacement motor. I was amazed by the power it put out and pissed when I had to drive my stock motor home. They are very knowledgeable and easy to work with. I liked it so much that I immediately ordered one. I am getting it put on next week and will post the results.
.... Did you account for connecting rod bolt stretch? When an engine is revved, the rod bolts stretch like rubber bands causing the big end to become "egg" shaped momentarily. As forces increase with power adders.... ...the more negative effect on rod bolt stretch you have... .... Not to mention the FACT that these engines have torque to yield head bolts coupled with aluminum head and composition head gaskets. Do you see where I'm headed here? Those head bolts are good for ONE use. Just ONE. When they are torqued at the factory, that is the LAST TIME that they can EVER be used. That's why new bolts are included with a head gasket set. They stretch to acheive their last torque value. If they stretch any farther ...
When a bolt is torqued it is put in tension and the part it is clamping is put into compression. A torqued bolt does elongate when additional forces are placed on them, but so long as they operate within their elastic range they are fine.
The stress you describe on connecting rod bolts does not make sense. You only increase tension by increasing RPM's & I don't think a blower would do that right? That's not where I would be concerned.
Now head bolts are a different animal. If you increase the pressure in the combustion chamber (which I assume a charger would do?) the bolts would cycle closer to their yield strength, which would ultimately decrease the expected life of the bolt. This is the effect of fatigue in designing with metal. However, since I don't know any of the specs on the bolts or how much a charger increases the stress in the metal, I can't determine if there would be any measurable effect on the expected life of the bolt.
In real-world terms, how do those rice-burners perform with blowers? They've been putting bolt-on chargers on those little Honda's for years. I've got to think the 3.8L is a lot closer to those engines than it is to a 350.
Well I don't know about the rest of yall, but I appreciate RIPP continuing this discussion. He's answered every single question and concern we've thrown at him. .....and not just with sales jargon, I don't believe. Although we've not seen any real world numbers yet, I'm sure we will as time goes on. He didn't have to keep going with this thread. He couldda jusd said to hell with it. Thanks Ripp. ...and let me know too when one of your Jeeps might be in Georgia. I'd love to go drive one. If I decide to put a blower on, yours will likely be the one.
