I grabbed this link off the other site and just thought you guys might like to see it.

I love the concept but the execution leaves a bit to be desired. I really like how short the CAC piping is w/ this system and the 4" diameter of the piping. I also like the additional air flow this system allows to the radiator, etc.

Someone mentioned that if it was built into a hood scoop hood and lifted w/ the hood it would be more practical. I agree.

It's nice to see someone thinking so far outside the box though.

For a pulling truck on a single hair dryer I would consider something like this personally.

I agree that it might be ok for a puller but even that is questionable since I'm assuming it's outside the truck to take advantage of air flowing over it and you just don't get going that fast at a truck pull. Other than that I wouldn't want that creature sticking out of my hood.

Hummm.... I wonder why the hot ticket on most cars that come with hood mounted intercoolers is to go to front mount?? Could it be because hood mounted intercoolers see very little airflow? For the most part on any vehicle you end up with positive pressure in the engine bay behind the radiator - that air has to go somewhere. Plus, there isn't much pressure to be found in the center of the hood when going down the road... About the only place you get good outside pressure is the cowl area, and once again you have to overcome the engine bay pressure underneath it before you'll get good airflow through a cooler placed there.

I think it's great that they are trying new things, but I don't think they are going to get anywhere near the efficiency of a good front mount intercooler.

Why would you want an intercooler over a diesel motor that runs so hot? Heat rises right into your intercooler... I personally think its a great thoguht, but a bad heat transfer idea

Ship it to your buddy at DPS and maybe he can improve on the design.

Wonder if AutoJim will chime in? =)
I do agree that with a scoop to force the air down through it, it could have some possibilites

 

[emrgnc]

Hahaha....all it would take is to piss someone off in a parking lot and have them take a knife to it.....I dont think so Tim!!!

Ill keep mine right where it's at.

"The only pressure fluxuations will be towards making more boost, power, torque, and better fuel economy while making lower EGTs the whole time."

I was under the impression that if it flowed better, you'd see a slight DROP in boost numbers.

Do they have any numbers on it? I'm sure somebody's gotta have one.

Wouldn't it be a better intercooler overall if a hood scoop was used? Like on the WRX STIs?

 

[AggiePSD]

GSP did this a couple of years ago on his OBS and back then everyone told him it wouldn't work. Shortly thereafer he quit playing with his powerstroke and moved on to other things. /ubbthreads/images/graemlins/shrug.gif

Never heard of that company, but might have to give him a call and check it out myself! /ubbthreads/images/graemlins/eek.gif

 

[DSTRBD]

wow.

 

[ptsuperd]

Anybody see the intake they sell on that site? I wonder how that element compares in size to a stage 2 AFE? I do like how they relocate the battery.

checkerplate is cheesy though....

 

[02Powerstroke]

Just thought of another thing.. if the intercooler was there it would mean that you have a lot of parts to remove to do the slightest things under the hood

 

[Zro]

Yes there air intake was discussed on this forum a little while back. Looks cool, especially with the rifling effect in the tube. Thing is, it's kind of expensive. Plus there was the whole debate on whether or not you want the air to rifle into the turbo or go straight like the Tag 1 and 2 do. /ubbthreads/images/graemlins/shrug.gif

 

[imelmo]

Plus it says it uses a K&N element.

 

[Zro]

Yeah but as far as that goes, I don't see how hard it could be to take the pos off and swap it with a good filter.

I was thinking that it would be more wise to have a backwards facing scoop and to try and use negative pressure to draw air from the engine compartment out thru the back of the hood.

Under hoods temps actually aren't as high as you would think going down the road. Only about 15 degrees higher than ambient according to Beddins who measured it. If you removed the front mounted CAC which adds underhood heat, kept the air always moving from the engine compartment thru this CAC, and ceramic coated some under hood parts you might find that the temp difference is even less?

Freddy, aren't you the one that spent 6K w/ DPS and sent him rods and a girdle that he then copied? And your implying that I send him parts to copy and he is my buddy? Stop trying to make me look like a bad guy and calling him "my buddy" just because I bought something from him once in one phone call and gave my honest experience regarding the transaction and product.

 

[WUNDERHOOT]

it looks like race stuff to me . like on a sled puller the speed of the wind going through the grill is not that much anyway. i think allot of these sled puller are not even running a aftercooler anyway. this thing might could help them. i wonder if you can throw a few bags of ice on top of it ? spred the ice out over it like charcole? i know this thing aint going to sell for street vehicles. i think there air cleaner looks like doodoo. i would get the afe . i could make that thing there selling it takes up half the engine room and it looks like they made it with a swazall.

Well, it's certainly *different*.

Someone remarked that all the Subie hot-rodders are moving the top-mount CACs on the WRXen to front-mounts -- this is true, primarily so they can get more core area, but also to get cooler air with better delta P across the ambient side of the core. The Subies have scoops on the hood to gather air for the factory CAC.

The problem with the hood-mounted CAC, no scoop, is that airflow over the hood of the moving truck will actually draw hot engine compartment air up through it, not down. I'm sure the writer of the breathless prose on the page advertising this thing meant that the radiator fan blows air up through the CAC, not draws air down (from outside) through it at idle, which would be a *really* neat trick since this core is on the discharge side of the fan, not the suction side. The "1000 CFM" fan is maybe moving half that with the system restriction in play -- and much less than half if it's actually trying to draw air down through the core instead of blowing it out the top. When you have to fight the natural delta-P setup, aiflow suffers mightily.

Also, the OEM fan pulls considerably more than 1000 CFM, even through the OEM heat exchanger stack (condenser, CAC, TOC, rad).

Anyway, the idea of a shorter inlet tract reducing lag is solid. The aero-thermal effects of a top-mount CAC are considerably less so.

Subie uses them on their flat-4 engines for packaging reasons, primarily -- and on a rally car, which the WRX/STi are homologation specials for, it gets it out of the rocks and stones zone. That's a specialized application.

Don't think I'll be spending money with these folks. At least not on this product.
