I said throttle response, but there is the whole turbine in standing in the way of exhaust escaping thing...

Man, we hijacked this thread pretty good!

OP- That Kenne Bell kit makes SUPERB torque down low, even though I voted stroker.

The main attraction to a stoker (I6 jeep motor that is) is the bang for the buck. You loose that value with the 4.9L.
Not true. The Titan 4.9L Stroker is $3,500 which is the same price for the Golen 4.7 Stroker. However, the 4.7 from Titan is about $900 cheaper than the 4.9L. I spoke to both company's and I like the back ground and detail work done to the Titan motors. The 4.9L will give you 315hp and 345 on the torque. The 4.7L 285hp and 310 torque. Yes, more money, but more power I feel well worth the price. With that much power does one really need the forced induction?

Just what is the detail and background work you like from Titan over Golen's strokers?? You do also know about the additional items you will need on both engines right!?

from my limited knowledge id agree with almost everyone above. you wont lose any low end grunt but your not going to gain anything off the line. if its also a dd i would go with a turbo instead of any other option. if you can manage to stay out of boost, you can get good (for a jeep) gas mileage. with a supercharger your always boosting unless your completely off the gas. i want to eventually turbo my wj so maybe im biased. just my 0.02

Every time I read a thread on Jeep forums about forced-induction I die a little inside. Get frustrated, and can normally only bring myself to post something about lots of mis-information...

Reality for most people, you should do what best fits your mechanical ability and budget...
If it were me, I would without a doubt go 3/4 Gen Chevy V-8.

No that would be the 5.9 in the 01.

All I know was that it was a 24 valve inline 6 and it had masses of power.

I love these threads! Blaine, I have seen your truck and its massive! My wife loves your camper! I hope I can haul my family / jeep / trailer up on a run during the holidays! I just got an 8.1L Suburban and looking forward to seeing if that 450 ft lbs can pull it all. I wanted a diesel, but was scared to deal with a used one.

I know one of you JF guys (I forgot who) put supercharger on his. It has a highway shutoff so that its not wasting gas. Then he scored a sweet older 4.2L and used it to stroke is motor too! So don't ask which one, do both! FYI: He said he ran 6lbs with the supercharger and lost 3lbs after stroking. So stroking gives you the equivalent of 3lbs boost (based on his 4.6). So he changed a pully out and put it back to 6lbs of boost. I think I read someplace that each lb of boost is about 12 ft lb. I like the 4.6 for reliability, don't forget to tune it!

<<>>EDIT FOR GRAMMER AND MISSUSE OF WORDS.....and BTW the supercharger that this guy had was an Avenger.

Not so much detail than not seeing where the extra grand is coming from... You get all the seasoning and machine work with Titan that you get with Golen, but the price difference becomes confusing. Look, I'm sure that both are great builders.

As for the additional item, yes I know what it takes. I just like to hear what others are doing, planing, and thinking about when it comes to forced induction or strokers.

One of the facts that I have come to terms with is that my present power plant is very healthy at nearly 90K miles. So, why rip it out to replace it with a stroker when a simple supercharger will work just fine for my needs.

Just learning by listening...

First off, Titan has HORRIBLE reputation, at least on naxja.org and jeepstrokers.com. I have read many people describe all different kinds of failures from them. Just do a search on those forums. That being said, I have never ran a titan stroker (nor will I) so this is all second hand internet "knowledge" so take it for what it's worth, and also, I just had to replace my camshaft in my Golen stroker, so they aren't perfect either. Lastly, unless Titan is using an expensive custom offset ground crank, their stroker is NOT a 4.9L as they advertise, and I doubt they are for that price.

Bottom line, 258 crank =

4.5L stock bore
4.6L .030 over bore
4.7L .060 over bore
4.8L with a 4" bore, and you are REALLY pushing the thickness of the cylinders walls at this point

Anything with larger displacement is going to require using longer stroke than a stock 258 crank. Also, the small gain in displacement doesn't do much for you, especially considering the cost in parts that CAN'T be picked up at autozone for under $200.

BTW no matter how good you tune a turbo there is ALWAYS a lag in the turbo kicking in. I have even seen guys run them with one small and one big. Theory that the small spools almost instantly then it spools the big one faster. They basically come on hard around 3k. That is why guys don't normally run them. A twin screw blower has power instantly and almost makes a perfect graph. Meaning it makes almost a perfect table top on the the chart power goes straight to peak and stays there from 2k thru 6k or what you have it setup for. Issue is I don't think they make one for a 4 cyl or 6cyl. I know you can make one off of a supercharged ford thunderbird.

LOL,. I'll run a turbo over a supercharger. this is some of the stuff I custom build and put together.

The chevy is a street legal driver with around 1100HP.

How bout twins on a 6.7?




it's already been said....... proper set up/size can have no lag and blow a supercharger away.

People who make general statements about power adders, what they can and can't do, and where they do and do not belong have no idea what they are talking about and should stop commenting. You are not speaking from any real world experience and you are just repeating what you heard some other guy repeating about what they read on the internet.

I considered both and decided to put an L-76 V8 in my 98 TJ. A cheaper option would be to salvage an LM7 powertrain/harness/computer from a wreck. These gen 3/4 GM V8s put up amazing numbers with incredible dependability, and they can be adapted pretty easily to a TJ.

Well, I was planning to go ahead and order the Kenne Bell supercharger and would you know it they stop producing it! Crap, this always seems to happen to me. I am not real sure about the Avenger and the RIPP is somewhat new. Now what? I guess the KB units were not selling enough to keep producing them. OK turbo guys lets hear it cause I know its coming...
