Jeff,

Is your radiator still in the stock location, if it is you are not getting the full benifit of your IC like that. I see how your getting air to it. If your going to keep it like this and your radiator is in the stok location you will need a pusher fan on the bottom of the IC.

I remember you were going to do a top mount and I said it would be a bad idea. I misunderstood your or whoevers definition of top mount. Top mount is the FC and STI/WRX/Subi stlye.

I guess this is a half vmount. Hope it works well for you.

Ben

That is how it already is.

The intercooler is always cool to the touch and is often well below ambient.
I had quite a few people do double-takes at auto-x this past weekend when I had them touch the IC after a full-out run.

^ Where does your intake run to? Is it in the engine bay below the IC above rad?

The air goes through that path, but it comes in through the "mouth".
I use a modified AEM intake, which hangs the filter out in front of the AC condenser.

No, you are running a puller fan. The IC takes air in from the top with the help of the puller fan, right?

That makes this a "7" mount.

No. PUSHER.
Air goes OUT the hood, not in.

I get the idea, that air comes up from the radiator opening and out through the IC, but I had the same original thought when I saw the angle/direction of the "scoop" above your IC... the sloped front end looks like it would funnel air over the IC, but the back end looks like it's meant to force the air down and in rather than allow air to flow over.

Not arguing the form/function of it, just saying the "scoop" makes it look otherwise.

The underside of the IC sits in an aluminum tub (a customized version of the BHR intake shroud) that is ducted to the front opening of the car so that it isn't bathed in hot air from the rad.

The area directly above the scoop becomes a low-pressure zone as soon as the car is doing more than 30 MPH or so.
The air moves through the IC however it pleases - sometimes it is going in and others it is going out the scoop. The fan is just there to make sure the air is always doing something.
The end result is that the IC is always around ambient or below.
I know the whole thing is counter-intuitive and probably goes against some sort of man-law here on the forum, but I don't concern myself with such things.
I build stuff, I test it thoroughly on and off the track and I move on if it doesn't work.

This works.

We all are, like it or not.

For me, the "theory" is less important than the result.
As a kid, I was always the one that intuitively knew the answer to the math problems and then had to figure it out backwards to show my "work".

You did notice that my post was in the form of a question, right? Like this one? Or do forum rules prohibit reading question marks?

Ah-ha! I was deceived by my eyes. The eyes play tricks like tiny round devils!

The explanation of the "tub" answered my next question too.

Good Job Jeff. Yeah the pusher fan's the key. Alot of guys running vmounts still do not use pusher fans on the bottom of the IC and rely soley on the hood to aid in cooling. It works but not as well as the pusher fan. I did not read everything but do you also have it tied into a senor to tell the fan to turn on and off at certain temps. Some people tap it into the rad fans, some the air temp sensor. I like to run a seperate set-up for this to control/regulate when the fan kicks on.

I have it tied into the low/high circuit for the right fan, so it blows at half-speed at 185°F coolant temps and high-speed at 195°F.
Which means it is almost always on here in Arizona. lol

I don't care for dyno numbers, just want to convince myself it flows as it has to.
A dyno will show you how soon how much power it makes and I think that is important. Say it peaks a good number of 315 rwhp but it doesn't hold near that number very long, or maybe it makes low power until 7000 rpms. I think these are important things to know.

I looked at the dyno for MM's upgrade and it makes over 270 hp from 5500 rpms and up, thats pretty damn impressive. If I'm going to drop $1000 on a turbo upgrade I want to be sure I'm getting enough of an improvement over the stock Greddy first.

I like the design of water cooling as well, but I would like to see what kind of difference in temperatures there are.

there's a lack of owners wanting to put a effort to raising the boost with all the fixes..the pattern is they start off strong then decide to part out and sell their cars before seeing results..i eventually plan on producing results and information once another dyno day comes around

Dyno is helpful, but simple g/s log will do for me.
Anyway. I asked MM for advice, he didn't respond (that's ok) so I ordered BNR and waiting.
Got a used greddy kit with bad crack and hole in the manifold. Got it repaired but don't know how will hold. But I've sourced some new ones for grabs.
Ready to play in a couple of weeks.

I've seen 290 WHP with a stupid huge boost leak... so I'd say this packs the goods, just have to let it mature (like everything else on this car).
