It works! BRUHAHAHHAHAHHAHAAA

The Moose Truck is officially intercooled! I'll have to adjust my sig. Just came back from the first test run. I have two test hills that I used as a benchmark, and here are my results. All tests were made in 4th gear at 55MPH. First number is boost PSI, second number is EGT's.

Hill 1 - Old 4 PSI @ 900
Hill 1 - New 2 @ 800

Hill 2 - Old 3 @ 675
Hill 2 - New 0 @ 600


Hill 1 is steeper, but hill 2 is longer. Most importantly, I found myself having to back out of the throttle to keep at 55! I'm extremely satisfied with my cheap ebay CRX intercooler, and my 30 or so hours I put into it.

Thats a nice reduction in EGT's, I would think you have more than made up for the small loss of boost with the significantly cooler charge air.

I guess also that it is not loading the engine as much and therefore does not require as much throttle, therefore makes less boost while still producing the same power.

so does that mean the pump will make it up another flat? it does have a moose pump, right?

i have a semi small rx7 IC that i guess i could use.. how big is the one you are using?

Nope Way to small,.

Congrats Mel, Got some pics of the install yet,..?

I kinda had the same idea, but using an IC from a Toyota Supra. Way too small for the amount of air flow we'd need with these engines.

Mel... You used a CRX IC? When you say CRX, are you referring to a Honda CRX, or is CRX the brand name?

The ebay seller is CRX Racing I think. They offer a lot of intercooler kits for rice burners. The one I used is one they sell for a Mustang. I think it is 3" thick, by 22" by 10" or something like that. I got a PM from a concerned individual calling me on the carpet for using a Chinese part. I appreciated his doing that, as I don't want to be a hypocrit. As for why, the market is very limited for side inlet/outlet coolers, and my physical dimension requirements were very stringent. It seemed I had no other option, and I lack the fabrication skills and tools to do that kind of alluminum work myself. I actually don't know where the stuff came from, and none of it says made in china on it, but I can't imagine it is coming from anywhere else given the price. I used a $60 cooler. Hypermax' cooler has another zero behind that. If it makes anybody feel better (and it does me), I spent $400 on a new intake hat and 2 pipes from Hypermax, so it's not like I did this on the cheap. I'll get more pics today, but here is what I have so far.

just a brain fart i just looked at his sig it was the moostang that i was thinking of, dosen't have a moose pump yet.

Way to go Mel!


I'm jealous.

Thats pretty sweet. I was thinking of cutting a 4" hole in my firewall and hooking my intake tube to one of my A/C registers since I can't afford an intercooler. j/k lol.

Here's a couple top side views of the finished project.

Congrats Mel, nice work. Your post has got me thinking though.
My truck has a non-wastegated PSD turbo fabbed in, and the intercooler went on at the same time. I get 5-8 lbs of boost with this set up. I wonder, would I get more boost without the intercooler? EGTs are already high though pulling something up hill.
I have a parts truck with a blown E4OD, but a wastegated banks sidewinder and nice exhaust. After I towed it home, I got about a half mile out of it before the tranny completely let go. I saw 10-12 lbs of boost easily(albeit breifly). I plan to swap the banks onto my truck (I've just never been happy with the PSD setup). If I intercool it, will I lose boost ?
Hmmmm........

Interesting....

you will lose boost through any intercooler almost but it lowers the temp of the charge air and colder air is more oxygen rich, leading to a better burn despite the lost boost.
