Twin Screw Supercharger!?

[John(XJ)Jeep]

I just came across this now and it seems to be around for a little bit but was wondering if anyone has a more in depth look at this product. It's seems like a good way to go but not sure at all. The link where I found this seems to imply that this supercharger was ment for the stock 4.0.

This is the link to where I've got to know this:

Just any comments, impressions or questions would be appreciated. :cheers:

I know this already, as I have posted a few on them too but by this question I meant this particular supercharger specifically. I know how they work and I know the differences but I'm looking for feedback on this particular supercharger not superchargers in general. Hmm, maybe I din't make my first post clear enough.

Umm Im a slight bit lazy right now to click on your link but I assume youre talking about Avenger Superchargers. They are a company in Colorado Springs, Colorado. Check out their site. Has some info. Im going to try and check their place out, just to make some new jeep connections.

Hood modifications and/or 1" body lift required.


hmmm the xj/mj supercharger kit may require a body lift..............................

hey on the plus side for those guys, if they can manufacter a body lift for the XJ, imagine the money they would rake in... they'd have the market cornered.

[lost1]

yeah, that and blinker fluid.

The mechanic at the stealership tried to get me with that one...I asked him if I looked like an idiot, then told him to get back to work changing my muffler bearing.

you can see pics of the "hood modification" that would be necessary here.

It sits quite a bit to the left, it'll look odd but it seems like a good oppertunity
for a bit of ventilation and hood entry for intake. Might have to make something
custom for that though.

Too bad most of these companies that advertise their products lack good detail
and high res pics for people to see what it's all about.

Thanks for the pictures.

how are you gonna do a "body lift" on a unibody xj?

[Boostwerks.com]

So how much do these kit's run? I've been wondering this for a while, but their site has been "under development" for the past 3 months.

Also I know that the XJ they put their kit on just has a huge hole in the hood and the scoop to cover up the blower. (not very daily driver freindly)

[djblade311]

maybe you can install the cowl hood from quadratec to accommodate..

Possibly, but I think the SC get's mounted more towards the drivers side which would be a place where the hood wouldn't help.

We need more pics damn it. :(

[djblade311]

ok...so who's gonna buy this thing and do a write-up? I can't because i've already spent too much prepping for the FF

[Gil BullyKatz]

IIRC...

The avenger Sc is a whipple twin screw and was $3-4k?

Kenne Bell has a sweet twin screw with an intercooler and boost/fuel management but is $4-5k... It's for a TJ but I'm sure it would work on an XJ...

The kenne bell sc is the exact same as the avenger super charger. I can't remember what one came first, but one of the two bought the patent from the other if I remember correctly, so you're buying the same basic thing but the extra's that come with it will vary based on the company.

They both use Whipple's impeller unit...

but KB uses their own IC design and fuel mgmt system...

which is why they charge an extra G

if I had the extra $...

Kenne-Bell hands down.

Their real world experience in blowers is a non-debate.

avenger does not tune your jeep for the supercharger,kb does but limited to sertan years. i know a couple of people not happy with the avenger.

You're right.

I remember reading a few posts a year or two ago about problems with Avenger's setup...

Time for a stupid question, brace yourselves.

that scoop's giving the added benefit of providing additional airflow, true, but if you already have a cowl induction hood, wouldn't it actually be better to make a fully enclosed cover for the part of the SC that won't fit under the hood, in order to better protect it from the elements? The cowl induction provides superior airflow under-hood, I've seen that proof with my own eyes over the last summer. But surely a scoop that ugly isn't necessary for peak performance. Right?

[53guy]

Yeah, but the problem with that is you'll have a cowl induction hood with a huge ugly bubble in the front. Either way, it's gonna look ugly unless you mount your supercharger like Hesco does, kinda laid on its side below the intake manifold. The reason is because the superchargers from KB and avenger run their pully directly out of the compresser, making it pretty high at the belt, which if you look at it, is pretty close to the front of the hood. Just a thought.

The scoop that they used was JUST for add clearance under the hood. The blower will not fit under the stock hood. The blower is getting air from an airbox or open filter somewhere in the engine compartment. The could have used a rear facing cowl hood or just slapped a fiberglass box on the stock hood to accomplish the same thing but they are trying to be eye catching and sell a product so they went with a prostock style scoop. So yes you are right a rear facing hood will protect it better.

[lost1]

well I was talking airflow in terms of cooling the engine compartment, not intake, but I guess the gist of the idea got through.

I really, really want to find an old crappy cowl hood and give it a try. I want to fab up a smoked plexiglass bubble/box thing that would allow a supercharger to fit and be well-protected but visible. (what can I say, its a show-off thing.)
