Cold Air Induction System

[Hotwheels]

Has anyone used the Hypermax Cold Air Induction System on thier van??
If so how did you like it???
What benifits did you see?

they say 200 degrees less exhaust temp??

My understanding it that this is simply an intercooler ... which I also understand will not fit on a van. Youmay want to doublecheck.

I can certainly believe it won't since I was looking at mine today and finally realized the only reason to have a hood on a van is to let give us something to open and look into to see if the engine is still there. Damn is that tight/full. Bet you could pour a bucket of water in there and it wouldn't run though in 3 days....

The following is the text just as they have it on their internet add. I just copied it off!


Hood-Mounted Cold Air Induction System
for Turbocharged 7.3L/6.9L Diesel Ford Vans
A Hood-Mounted Cold Air Induction System, offered by Hypermax Engineering, Inc., is designed specifically for the turbocharged 7.3/6.9L Ford diesel vans. The cold-air induction system provides cooler turbocharger inlet air temperature and lower air cleaner restriction reducing exhaust temperature up to 200o F. Increased turbocharger efficiency and engine performance are the results. The system includes reverse fiberglass hood scoop that inducts high pressure air forward of the windshield, a low restriction air cleaner and housing, as well as all piping and mounting hardware for easy installation


You can see why I am interested.

I sent them a e-mail will let you know when i recieve a answer>

I wrote Hypermax about the van scoop months ago. "No gains for a non turbo motor" was their reply. Call and ask 'em yourself!

BoswellBear - you must have a new PSD, heck, I have a small bucket of oil (engine, PS) spill out every week.

[Hotwheels]

You are right. I am going down to put my 2000 e-350 on order next week every thing i read says its a turbo diesel.

Well guys this is the reply i got from Hypermax


>>How big a hole do you need to cut in the hood?
The hole you cut in the hood is 6" x 9".

>>Any test results from this conversion??
We do not have any test results from this conversion in printed form.

>>Anyone to talk to that has performed this conversion?
I'll try to get you somebody's number for you to talk to.

Thanks
Hypermax


I think we need more info before i cut a 6 by 9 hole in a new y2k.

Ok Hotwheels,

You got a bit more of a less straight foward answer then I did. As I wrote before, HMAX told me no gains for a non turbo. What they told you seems to bare this out.

There is a good reason an intercooler (or aftercooler) doesn't help a NA engine. A turbo, because of the compression action of the intake air, heats the intake air to somewhere around 300 degrees F. Years back big diesels used coolant to cool it down to around 220. All big diesels are now ATAAC, air-to-air aftercooled, which cools the intake air to within 15 degrees of ambient. The cooler the air going in, the more air you can push in and the cooler the internal parts are. Like turbocharging, this "additional" can be used for more power or better fuel economy or longer engine life or a combination thereof. In a NA engine, the air is already at ambient temperature going in, just not pressurized.

It is true that an intercooler won't help an non-boosted engine. Where would you even put one?

The Hypermax cold air system brings cold air to the air cleaner. It is not an intercooler.
I have an information package, but I just couldn't see cutting a hole and mounting a scoop on my hood!

Well, I am probably goofy enough to cut the hole and mount the hood scoop on my 99.5 van, and frankly cooling down the air intake isn't a whole lot different - in theory at least - from coooling down the air via an intercooler on these things, but I would sure like some empirical evidence that it actually does work. Maybe I'll have to put on the full guage set (plan to do it anyway) then go ahead and make the change.

See what the EG temp is before and after the change. If I do it, I'll let you guys know. Perhaps I can talk Hypermax into performing the necesary installation so they will know it was done to their specs.... Still like the idea of the behind the bumper intercooler, though.

Old broken record here:

Yea, the HyperMax kit I'm talking about is the cold air unit, not an intercooler! In van land, we would pay almost $300 bucks for the cold air kit, as opposed to th pickups under $100, typical, no? If the thing worked, I'd cut a hole in the hood no problem, but the Hyper Max folks say it is a waste of $$ to do so on a non turbo motor. Go figure.

Food for thought. I had just recently fabricated my own cold air inlet and a 4 inch muffled exhaust system for my '93 7.3 IDI. My exhaust consists of stock headpipes with an ovalized-to-4 inch slip fit tail welded drectly onto the y-pipe. I then ran a Hypermax muffler and the exhaust exits in the stock location. Now for the cool stuff. I am drawing fresch cool air from above the driver's headlight, between the hood and rad. support. I had fabricated an aluminum panel that goes from the firewall to the front of the rad. support with a 75 degree bend dowm four inches to the top of the headlight. i then sealed the inner edge parallel to the fender and the firewall edge with two inch foam "padding" to seal the cool air intake area. I mounted a two-inlet NACA duct with each inlets diameter being three inches onto the plate after carefully cutting a triagulated hole. The inlets each have a three inch hose, one routing to the front of the air cleaner and the other to the driver's side. I had to take the stock air cleaner and cut off the factory inlet opening, weld it shut, rotate the housing , cut and weld two three inch steel inlets to fasten the air tubes to. This modification took about a good afternoon and is actually fairly straightforward. I have noticed an improvement in accelleration around 30-55mph and my EGT has been aroung 100 degrees cooler while cruising, it seemed to have no effect on full throttle EGTs, which on my van are around 1250-1275. If anyone is interesed in more info, let me know I could possibly send some photos out, sorry no digital camera.
PARTS NEEDED:
Al. panel, 17 wide, four inch long tab on front of van, angle cut at rear
NACA duct, two 3 inch inlet can purchase through PEGASUS AUTO RACING
8 feet Al. dryer flextube
2-3 inch tubing , measuring 2 inches long
steel plate to weld stock housing hole shut
2 inch x 2 inch Foam seal (AKA camper top tape)
