Supercharger question

Anyone have any experience with superchargers and the 4.0 motor? I seriously thinking about it for my 2004 TJ automatic. Specifically, I think I like the Kenne Bell Twin Screw 5.5psi and looking so see if anyone in the club is running one. Also trying to find someone "experienced" to install it. (don't think I want to mess with it myself) I have a few contacts who do alot of "import tuning" on honda's and toyota's but not sure I want them messing with my Jeep. Any thoughts would be appreciated..............................

Any suggestions on a better kit or are your comments in reference to superchargers in general? A friend has his vette supercharged with a Kenne Bell and hasn't had any problems in 1 1/2 years. Slightly different set-up though (lol) and he had it installed in michigan before he moved out here.

honestly the best and most beneficial thing i have seen so far is the turbo kit from www.505performance.com comes with everything you need and cheaper than the charger kits....the guy who makes these told me the stock motor and turbo combination on tj will beat a small block 350 yj on the quater mile all day...hes done testing.

Because Jeeps are racecars... J/k Why not get AEV to swap you into a Hemi with all that dough??? Only 19,000...

Thanks for all the information. I'll definitely investigate the turbo kits. As far as what I'm trying to get out of it, we'll I want to run 35's and not feel like I'm struggling on the road to do 65 mph when I'm going uphill. I have 33's right now and getting ready to purchase/tow a 4-wheeler around. Even without towing anything, I feel underpowered.

As far as an engine swap, I'd love to but I'm not even close to a mechanic and afford parts + labor for something like that. I figured the SC or turbo would come in substancially less.

Hey - what changed from 03 to 04 that would make the 505 kit not work?

They do make a system for the 05 and 06.http://shop.505performance.com…?productId=2&categoryId=4

nvrmind, I see the one kit runs 2000-2004

But, really that is alot of money for what you are getting. If you could make your own turbo manifold and piping then you could build the system for way less. The only custom pieces on the system are the piping. So, everything else is available to buy seperate. I know a fair share of turbos, how they work, and the components of a turbo system. I've had 2 turbo vehicles, an srt-4 and an evo-8. And most complete turbo systems even then are only around $1500 and $2000. If you have the money and don't want to deal with the hassle get the system, but if you want cheaper and get the same results then piece it together.

atcually i have no idea where you got that price at because the hemi conversion minus motor we sell for $3k and the Brute kit for a TJ is only $9k, Quadratec sells all of the AEV stuff now and we have wheels in stock too. The 17" ones are on the way. We also sell the Highline Fender kit, i think its aroun $2k. We actually have a brute at work right now with the Highline Fender kit on a 2.5" OME with 37" IROKs.

I went to their website back in the summer just for sh*** and giggles. They'll only do hemi swaps with automatic trannys, they keep your jeep for about 2-3 weeks if I remember right. They install the motor, then run it for 200 miles as a road test and you get it back. With a new hemi it was 19K with a used it brought it down to like 13K. I tried getting back on their website and it seems as though it's under construction.

i think there are a few things that are neglected to be mentioned, one i like wippels stuff they make a twin screw, but im not sure if they make one for the 4.0.

now you said you want to tow wiht it, i would say get a super charger over a turbo, a twin screw( or a root screw) creates has a flat line psi curve so its has the same psi at 500 rps as it does at 5000, its good for towing so you get more hp at the low rpms, and jeep uses a inline setup beasue its it makes good torque, as compaired to a v6 set up.

now a turbo or needs rpms to make the pressure which is why you see them on ricers casue they reave up to like 5 6 grand,

now a i dont want to insult intelagence, so this is just to help
but a turbo uses exhaust to run,
and super chargters are belt driven so its till a super charger its it uses a turbine, but they call it a turbo charger, same thing as a turbo just uses a belt not exhaust. but heres a good web site it breaks everything down and lets you figure out what you want then beraks down the top manufacturs and who makes what for what rides
