Corksport made a better version of the MS3/6 TMIC. I ask if they were going to make one for the FC, seeing how there is no other intercooler upgrade other then FMIC or V mount. They stated there is not enough interest, however if their was interest they MAY try to make one. So i am here to see if there is any. I really think that having the intercooler on top safes space in front of the RAD. I Know they make some in japan but they run about $1,000.

 

YES! they should however, to really make it effective, they need to eliminate the cat elbow that bolts to the TB. the outlet to the intercooler and the inlet to the TB are the buggest culprits of poor flow

 

The problem with it ontop is the extreme lack of airflow you can get to it, and being heatsoaked by the engine surely isn't a help. Unless you're running a scoop the size of an STi, the stock location is terrible.

 

i was thinking about the lack of airflow. what if they was a electic ducted fan pulling the air down to the driver side of the engine?

 

I would be interested, but if it costs more than a FMIC/V-Mount option then I wouldn't buy it.
Stock location does have it's limits, but having the ability to simply swap in an aftermarket stock'ish unit is appealing.

 

so i was planning on designing an upgraded top mount, but since i have no hookups for production, id rather just explain what i planned since corksport will probably make my idea a little cheaper for me. so i was looking at mounting a small ducted auxillary fan under the top mount, as a puller wont affect the flow through the hood scoop at higher speeds. though for autocross and other track days, the idling at heat soak will kill our performance. then i was also looking at a dedicated place for a water injection, as a top mount will always have its limits compare to any other form of intercooler. i also was thinking an oversized core would be better, as the stock intercooler wont cool enough air for more than 250whp before being the biggest restriction in a setup. and even if the core is bigger than the scoop outlet, the air deflected by the core will still be pulled through the edges of the core as long as the fan is still providing a slight vaccum. then i wanted to make room for a cold side BOV as the hot side is never a good location for a bov thats not recirculated. so an interesting bend would need to be engineered between the end of the top mount and the throttle body to fit a smaller blowoff valve on the cold side. so yeah, thats all i came up with since i first thought about an upgraded top mount. hope corksport can use some of this, cuz i really am interested in this.

 

I think i should show them this thread. I figure If corksport started an interest thread there would be more interest. At this time there has been 150 or so views, i don't know if that is a lot or not. but it is something.

 

i summited a product idea form at corksport. 87TIIFC i copied bits and pieces form your post for the key features. I also linked this thread in the form as well as their facebook wall.

I really hope we could get a few more people in on this. the MS3 TMIC costs about $400 they maybe able to be the same, without a ducted fan kit. i bet they could sell it with or without the fan kit.

no point. RE amemiya made them and also sold them with the appropriate hood that has a wider scoop. think about it. why would you have half the damn intercooler not getting ANY air at all?

 

Doesnt ARC make one as well.

 

yup and so did greddy if i recall correctly.

best way to make it useful would be to convert it to an air to water unit like bdc did.

 

An oversized TMIC that isn't getting direct airflow is like hiding half your FMIC behind your bumper.

I like the idea of an upgraded TMIC. But it would have to be priced below FMIC and VMIC prices for it to sell. I don't know enough about such things to speak intelligently about it. But my guess is that it hasn't been done very often because the price gets too high and is competing with more accepted and popular cooling.

Anyone have pics of the Amemiya larger scoop hood? I've read about it but never seen it.

 

Upgrading a top mount is a complete waste of money. Put that money towards a fmic/vmic setup.

And a big lol to the one for sale in the classifieds that is nothing more than one and a half stock tmic's welded together for $400.

For that price you can piece together a fmic.

No. Think of all the heat that is in the top of the engine bay. A fmic is at least in the bumper and any parts not getting direct flow will still be in a cooler environment than the engine bay.

And that little scoop that doesn't flow anything until you get up to highway speed. A fmic is still not the best setup, but has way more advantages than any sort of tmic.

 

i have also have been throwing around the idea of a top mounted air to water intercooler.

 

top mount air to water unit would be something a lot of people would love to buy. no removal of the bumper, uses a 2nd stock oil cooler, and is activated by a simple thermo switch and a small fab. it would be super simple to setup and install. no cutting at all!

 

Keep the cost down imo. That will be the deciding factor to if it sells or not. We already know FC aftermarket is pretty small.

here is a my hks top mount

*btw , that really isnt an oem air box, just gutted as a cover I was trying to hid the efan and intake cone filter from potential law enforcement lol . If i had black intercooler couplings and black radiator hose, it could probably very well pass as stock

I have it out i could probably snap pics of it later.. Not to copy it but get some ideas to improve it.
I dont have the seal trim on the hood, wasnt on when i got the car.
I think the hood scoop could use a redesign. If they could perhaps replicate the Mazdaspeed hood scoop , but maybe without that lil middle point on it *i didnt like that point, looks too dodge ram-ish imo*

It should be designed with the idea that people will also be upgrading their intake system. I think that is something that can be made since there really aren't any "intake kits" besides going with hks, apexi and their kits are just air filters.

 

So if someone could make a air to liquid intercooler kit that is simple bolt in, you think people would buy it? In theory air to water would be way more effective that an air to air. do to waters higher specific heat. but what would people be willing to pay?

 

I did the A2W. No cutting. Short piping. I did remove the AC and lowered the power steering pump. I use a radiator the >size of the stock oil cooler, 400gph bilge pump, 2 relays (1 for fan, 1 for pump), ebay piping and greddy inlet tube. It works very well until the water gets heatsoaked, which take about 10 minutes to cool back down to ambient. With a reservoir it would work better and ice in the reservoir would be best. Around $500.

 

from what ive been reading, the radiator needs to hold twice the amount of liquid that the intercooler holds.

 

The reason i would rather have a air to air intercooler is because for autox a water to air intercooler already classes you into a super high class, it becomes more of a dedicated track car build. in BSP, i have a streetable DDable setup with street tires, although if i really wanted to be competitive i would need slicks. if corksport engineered the top mount, then they could very well make a water to air core that would fit in the same spot. water injection, on the other hand, is still legal for BSP. and if you were truly looking at performance, a meth/water injection system will still outperform a water to air intercooler without meth/water. so yeah, hopefully an upgraded topmount is available soon, if not when i get my hours at work back i will start working on a design with my little knowledge of mass energy balances and engineering classes from college.

 

10thaniv could you tell me more about you setup?

 

PM'ed ya.

 

thanks i got it, pm'd you back.

 

i would just like to see something made that isnt as restrictive. the outlet of the intercooler and the inlet to the tb change would benefit greatly.
