Looking for some ideas or suggestions on how to feed my procharger with cooler air. Right now my air filter is directly above the headers and sucking in hot air, I do have a intercooler in the car, but the position of the air filter is defeating the purpose (or not helping the intercooler) give the coldest are possible to motor. I was thinking of running an extension piece from the supercharger up toward the cowl to try in get the coolest air possible rather than sucking in hot air from the headers. (I have a VFN 4 1/2 cowl hood on the car.)


Any suggestions or pics would be greatly appreciated!!!

 

I think thats your best option

 

Yeah just run an extension, and pick up one of those cheap heat shields that go under the clamp on the filter.

there were acouple guys that made their own cold air setups for the procharger setups

 

Spectre sells some generic tubing and silicone unions. you may want to place the AF down low next to the radiator. sorry i have a Vette so not sure of a handy spot.

 

On the next one the TB on top was only there as a joke........




here is a video you can see it in better. I have a wide open intake or an air filter that I can switch back and forth easily. Basically it goes to the cowl so it gets a good amount of cool air

I can read the air temp from my cartridge maf and i can tell you, there is little or no difference in the air temp entering the engine if you get the air from above the header or from a cold source. I tested it by hooking up some 3" brake hose duct, same conditions with the intercooler pump running and not. Results were very similar, so similar that I attribute the difference as not significant enough to validate any gains from a cold air setup.

 

I agree with Twin_Turbo. Just made 1005 rwhp with no air cleaner at all. Heat from engine bay got handled through w/a intercooler. I know of 1400rwhp combo -same thing. The bends in the intake systems rob power more then the heat. Just my experience and .02 (I have a steet 400, with F2)

 

The heat clears out of your engine bay pretty good under driving conditions anyways.

 

Maybe convert the fog lights to a source of underhood air. adding a larger air dam may help as well?

 

Are you saying that cooler air entering the supercharger isn't as important do to the fact that once the air is compressed in the supercharger its going to be generating heat once the air leaves the supercharger? I remember reading a tech. article in a magazine that stated for every 10 or 11 degress of air temp. is equal to 1hp. Maybe this isn't really the case with supercharged motors due to the heat that is created from the supercharger?

 

and the intercooler will cool it down, one note is that I have and air to water intercooler and if I turn it on I can see the temps drop but with the pump on or off there is very little difference

 

I havent done any testing to see if there is a benefit to mine yet, so I can't respond to that, sorry!

 

Still havent made any moves yet on this cold air issue, but was hoping that someone might have some pictures of what they have done.

 

By physics this is impossible. Cooler air in will always be cooler air out after compression, unless compressor efficiency changes, which it shouldn't for a given pulley size and impeller speed.

If header air is 200 deg lets say, then compressing that air to 10 psi at 80% impeller efficiency would give discharge of 333 deg.

If you had ambient air getting to blower inlet, say 90 deg, then same 10 psi outlet at same efficiency would be 202 deg.

The intercooler has a set efficiency too based on ambient air and flow, or water temps and flow, but any help you can give an intercooler on temperature of incoming air should result in coolest discharge to the motor.

I did see a corvette guy see significant improvements when he cut his fender and ran an air tube outside of the engine bay. I need to look for that post

 

Here is a old link to a picture of Willie's setup https://www.thirdgen.org/forums/atta...-side-angle-01

There was also a guy on here named maniacc that had something similar but think his website is down. I'll look for some saved pictures of his setup, think I have them.

I also forgot I have my surge valve hooked up to recirculate the hot air to keep the noise down, I'm going to take that out and test the temperatures at the blower filter again and see if there is much of a change.

 

That air box/pan looks it would do the job, my only problem is that I'm running a carb. set up so I dont have the room that you EFI guys do.

 

I couldn't find any pic's of maniac's setup but I did find one more of *******. Think with a little sheet metal work you might be able to come up with something. One idea I'm going to try is go kind of straight down from the blower and see if I can suck air from under the engine. I see a pathway for the pipe to fit.

 

Before you jump off the deep end on that thought, I was talking to the procharger dealer that I got my setup through and was running some ideas by him because he also has a 88 bird with a procharger. One thing he told me is anytime you start putting elbows into the inlet side you start robbing air flow which he proved on the dyno. So long sweeps are the best bet which is why I like this air pan idea.

 

Yes I'm going to watch for that, I plan to test the intake temps before and after the supercharger plus watch for any psi drops. Though it would be only one elbow and straight pipe on the inlet side, I can't see it robbing boost that bad.
