Why doesn't Kenne Bell offer intercoolers? We do. Kenne Bell has been selling our own air to air intercoolers for the Buick GN for 13 years - and the Syclone/Typhoon for 10 years - well before the supercharger industry even considered intercooling. If intercooling was the way to go with our Twin Screw Supercharger, we would be using one. There are 2 ways to approach supercharging: 1. use a supercharger and/or boost that won't work without intercooling or 2. design kits with a supercharger that is efficient enough that it doesn't require an intercooler. Kenne Bell has chosen the later. First of all, contrary to popular belief, intercoolers do not "make" more horsepower. They cannot. Supercharger output is FIXED and doesn't increase merely because downstream air charge temperature is lowered. It's the same air by mass. The mass, the weight, the oxygen content of that blast of air discharged by the supercharger cannot be increased. You don't believe it? Try this. Capture the discharged air in a bottle, seal it and weigh it at 300°, 200°, -50°. The weight (mass) won't change, the engine can't ingest more air so it won't make more power. Yes, the cooler denser air, at -50° for example, will "allow" more boost or advanced engine timing but that air, by itself, won't make more power. Now if the air entering the supercharger (ambient) is reduced, it is denser and cooler and then will make more power (1% increase for every 10° temperature drop according to our data). So why intercool? If the supercharger is relatively inefficient with a high discharge temp and the engine knocks at 6 psi, then the air charge temp must be reduced. Retarding ignition timing or lowering the boost to 4 psi reduces power, so that is not an option. Fortunately, the Kenne Bell Twin Screw is the most efficient supercharger concept available being around 60° cooler than the competition at 6 psi, so an intercooler is not needed to remove an extra 60° from the air charge.

kenne bell makes some of the worst 5.0L blowers for power production . Look into the ati Procharger. about the same range and a whole lot easier to use an intercooler.

But he didn't ask about ATI Prochargers, now did he?

If you can't handle a little criticism, I suggest you not post in the first place. If you make a public post, you had better be prepared for public response.. good AND bad. Welcome to the Internet.

It's one of my pet peeves around here that people don't even bother to address the topic, .

Yeah, maybe it's unfair I'm taking out my rotten mood on you by calling you out on this.. but deal with it. I'm dealing with far worse than being called out on a bad post, right now.. you can deal with a little criticism.

ok, so....

sleeper, im interested in the twin screw setup for its clean apearance, and its simple ducting. those centrifugal blowers just seem too inefficiant and have alot in the way. besides, i'd have to put money into a higher flowing upper intake where as the twin screw is the upper intake. but thats just my opinion.

and besides, i dont even know if what i posted above is possible. i know somebody hear has a kb setup... i just want to know if what iv seen in all the photos is true, and if i ever do get to a higher boost application, i would like to be able to modify it for a intercooler. i plan on running it for a while wthout one, possibly selling it and buying a bigger one when i go to a 408 down the line... maybe in 3 years or so. anyhoo... its all hypathetical so try not to kill each other over a stupid question. :D

ok man.

What lower intake will you be using you could probly fab a elbow kind or what is used on the powerstroke diesels. Just an idea good luck on your project.

well if i do this, i'll be useing my gt40 intakes lower. so its gonna be ported out and puddle welded. then probley go and port out the kb air exit manifold and then i dont know, fab up some duct work, and yes lol, i was thinking of that elbo like the diesels have, except i got the idea from the fulie 460 intakes. if only i were rich lol, id be playing around with it rite now. maybe i can patent the idea and make the money back for the blower lol.

You know what? **** you, Asleep at the wheel. Welcome to my ignore list, asshole.

that might work to, im not sure how kb would react, or if they would answer any questions. i'v heard their costomer support sucks. iv also heard that people talking to them about intercoolers just get shut down lol. probley because they designed the blower specificaly not to use one lol.

Don't know if you have thought about this but there is an intercooler out there for the M90 on the GTPs, please don't shoot me for this.

Basicaly it mounts between the Supercharger and the lower intake. It looks and acks like a radiator. Two hoses and a small pump. You have a remote mount tank for your coolant of choice. Then the pump pushes the fluid throught the intercooler and back to the tank to cool down.

You may be able to make somthing like this.

No, I ment about the suggestion of using *GASP* a chevy part on our cars. But ya nice to know I'm not on the ignore list yet.

making smart comments not thinking of other on the board

Why lock it, Brian? Manson has a valid question.. and aside from the other shiznit, which I addressed by putting the one guy on ignore and laughing at the other guy who repped me, it's a topic we can pursue without too much .

EDIT: More silliness..

EDIT #2: You do NOT have my permission to pass along my ICQ # (if you have it) to people who are ignored on this forum, who wish to continue arguments after they've been dealt with. I consider that private information.

You could always do some shopping for an 03/04 Mustang Cobra intercooler and figure out how to mount it.

cooler for the 4.6 cobra replaces a lower intake altogether

The idea you describe reminds me of the EGR spacer on a 5.0

Nope the intercooler is mounted up front in stock 03/04 Cobra applications.  Sounds like your referring to the intercaooler Kenne Bell makes for the superchargers THEY make for the 4.6.  I meant the stock piece for Ford's eaton supercharger.  Something like this......  http://www.southfloridapulleyhq.com/SFPH/cobra/ec_iche.htm

Does pump speed vary with engine speed as a water pump would or is it constant?

even if it was just constant, you could hook up a fan with a thermostatic switch  on it. im sure running that pump constantly would keep the fluid pretty cool unless you were realy pushing the car for an extended period of time, like on the highway with gears. but in going that root, you now add the weight of a intercooler, and a radiator for the intercooler, pluss the fluid for it. seems to loose efficiancy having to add something else to cool the cooler. personaly i think it may be better just to have the ducting and run a front mount, instead of haveing it ontop of the motor, then running lines, pump, and heat exchanger with maybe even a fan.
