Custom Intake Manifold

so what kind of UIM is that ? from what vehicle ?

[robertisaar]

it's from a van.... i want to say the platform the Rendezvous is on?

LNJ, variation of the LA1 3400, found in the Chevrolet Equinox and Pontiac Torrent, but in reality it is a 3500 manifold with a modified top mount TB, that should give better air flow distribution to all the cylinders.......

No.

Yes.

Sucks that you still don't have the clearance needed. I may actually be able to start drafting a manifold design here soon, as I may have finally got a decent base to start off of. We'll see how it goes...

Let me know, I had toyed with the idea of going back to a custom LIM, but at this point it will be cheaper and faster to just go front mount like the old setup...

what you ought to look into is R-22 refrigerant, swap your heater core intercooler for an evaporator, and you'll have sub zero IAT's as long as the a/c compressor is going!

Well, no, actually you would not. That type of system is not efficient enough to handle the amount of airflow and heat generated.

Not arguing your point, but you might want to tell SVT because they do this same thing with the Lightning.

It isn't a full time system, it is a just a short burst, similar to the way an ice tank would work at the track......

Ford’s patented SuperCooler technology cleverly provides a special burst of power for the SVT Lightning concept. Traditional intercoolers dissipate heat from the supercharged air by circulating coolant through a front-mounted, air-cooled radiator. With the SuperCooler system, the vehicle’s air conditioning system is used to chill a small storage tank of coolant to about 30 degrees Fahrenheit.

On demand, the SuperCooler system switches the intercooler flow from its normal circulation and dumps the chilled coolant into the engine’s intercooler. In turn, the intercooler dissipates up to 20 percent more heat from the charge air - resulting in a denser air charge.

A green light on the instrument panel indicates the system’s readiness. SuperCooler is activated automatically when the driver depresses the accelerator to a wide-open-throttle position.

"This technology plays directly into the hands of the enthusiast," Coletti says. "The SuperCooler provides the edge for the driver, and it is done simply by taking advantage of the hardware that already exists in the vehicle."

As a result of this cool technology, the SVT Lighting concept can give its driver as much as 50 transient horsepower for short bursts of 30-45 seconds and regenerate within 2 minutes under normal driving conditions. While its effect is similar to that of an aftermarket nitrous oxide system, the SuperCooler is completely self-contained, environmentally friendly and regenerative.

No, they don't. What they use is a liquid-to-air system, but use the refrigerant system to pre-cool the liquid......

dude, it was a joke, but it could work with the right size, shape evaporator, it's really the same concept as an air to water intercooler, except a whole lot colder. the trick would be getting R22 not to turn the evaporator into a solid block of ice, that stuff's not like R12 or R134a(cheap sh!t), it's the same stuff residential a/c units use, and it gets F'n cold!

lol. So you want to make a miniature residential AC unit, with the charge air blowing directly across the evaporator?

[ericjon262]

no, not the residential unit, just the refrigerant (the chemical that, when decompressing rapidly, cools drastically)

[AleroB888]

I ask again: With the charge air blowing directly across the evaporator (thru which the evaporating refrigerant flows) ?

well, it's the coldest part of the a/c system.

See, they didn't go that in depth on the car shows on TV, or at the Chicago car show years ago. That and I didn't google it. They just said it uses the vehicles A/C system to intercool the intake charge. They do have a really nice idea there, though.
