RE Amemiya top mount intercooler
 
Does anyone have one of these who can give some feedback? It looks a lot more efficient than the stock unit, and I think it might allow for more responsiveness than a FMIC because there's less plumbing for it to go through. Of course I'm a n00b so I dunno...

Of course there will be alot less lag then an FMIC but any TMIC will get heatsoak, especially from our hot engines. FMIC or V-mount is the only way to go. If you could find a way to get rid of the heat soak on the TMIC then you'd be a god among men.

problem with top mounts are they heat soak easily. I also beleive aftermarket top mounts for FCs are tough to find. You can have a fmic, with minimal piping.

DragonRx7 05-08-06 10:21 PM

Less heat soak, less piping = V-Mount.

idsigloo 05-08-06 10:23 PM

V-Mount = alot of modifcations. Do a search for it and you'll see what I mean. I think J-Rat is doing a V-Mount project.

Greddy 32R FTW

DragonRx7 05-08-06 10:27 PM

True. But if you really want to do it, you'll get it done.

Hopefully I'll have my v-mount done around August. I'll make sure to take plenty of pics. ;)

Turbo23 05-09-06 01:15 AM

greddy system is such a large front mount, you really dont need something that drastic. V mount is ideal, or a smaller front mount, with air tight ducting, and if street driven, a very good efan and uprgaded radiator

idsigloo 05-09-06 01:20 AM

The problem I've seen alot with FMIC is that the coolant starts overheating alot easier even with a koyo radiator. Most have to remove the AC to assist with this problem.

I didnt notice any real decrease of responsiveness when I went to a FMIC. As long as you keep the tray that runs under the engine, seal off the top from the front bumper to the radiator, & keep the stock clutch fan & shroud you shouldnt have any overheating issues.

Where are the pics? Not that I'd suggest wasting your money on one, I'm just curious.

Apathy 05-09-06 06:49 AM

I didnt have any FMIC overheating related issues when I made the change. But I also make sure that I have coolant in my radiator(not water), I flush my cooling system periodically, I have a pretty nice e-fan that I scored from a buddy.

Turbo23 05-09-06 06:56 AM

well if you have a race car, or you live in a non freezing enviroment, pure distilled water is great to run. some of the cars at sebring have to run only water, which is better to disapate heat. I would but since I live in the north, I add alittle coolant

It's also great for turning the insides of your engine into rust and ruining you water pump bearings! Bad, bad advice. :nono:

What they do in race car cooling systems is totally irrelevant for a street engine.

jimmyv13 05-09-06 07:24 AM

I'd like to turn one into a W2A....

Anyone else think it looks like a polished up stock TMIC? Or maybe it's just me.

fcdrifter13 05-09-06 07:58 PM

I was gonna say the same thing except its a lil wider.

snowball 05-09-06 09:32 PM

thats just a stock someone welded another section onto.

86gxl_fc 05-09-06 10:05 PM

i was wondering something. a TMIC gets heatsoak from the actual engine? or from the engine bay being bottled shut? i was thinkin that maybe you can surround the top mount with some sort of airbox that keeps heat out?

91verty 05-09-06 10:31 PM

If you are not running high boost and other serious mods that would cause your engine to run hotter than normal, the stock tmic is suffice.

Alot of people are being misconstrude because of the intrercooer issues. I run a e-fan and koyo aluminum rad and i do use distilled water with a half mix of antifreeze on a stock turbo with only a mild WG port.

I noticed good drops especially in the Florida humidity. That being said, i would highly recomend spending your money on a e-fan that would cool you r engine significantly over the OEM unit. YOu will be surprised at the difference. But thats just my opinion.

That pic is off the RE-Amemiya website, so that someone happens to be the people who build some of the best RX-7s around. Which is why I posted this thread, to see if it's really any good. Would it be possible to insulate the bottom of the IC or the top of the engine if you will so that it isn't subject to heat soak?

idsigloo 05-09-06 11:14 PM

Doesn't have anything to do with how great RE Amemiya is or not. TMIC is just junk in the first place because of the heat soak. Doesn't matter that your reducing boost lag when the air temp is 200+

AUGieDogie 05-10-06 01:49 AM

Just outa curiosity, what is the price on this intercooler? I've never actually seen a site that sells thiem.

It doesn't make any difference who made it, it's still a just stock intercooler that's had half the core from another stock intercooler welded onto the side of it. It would reduce the pressure drop compared to an unmodified one but it wouldn't cool any better because the added part of the core would be getting zero airflow from the hood scoop. It would make a good FMIC though. In fact that's almost exactly what I'm in the process of doing...

I've insulated the shield on the underside if the IC but it didn't appear to do much for measured intake temps.

Both. The IC is heated by both radiant heat from the engine and by air heated by the engine rising up through the IC. Hot air rises and the hood scoop provides a perfect chimney for that hot air to escape.


i was thinkin that maybe you can surround the top mount with some sort of airbox that keeps heat out?
And when you're moving how is the air from the hood scoop going to get out? There's already a shield under the stock IC, probably put there to lessen the effects on heat soak and deflect rainwater away from the engine.
