Top mount intercooler

Has anyone here thought of installing a top mount intercooler instead of a front mount? I have been considering this recently, and was wondering if I am the only one who has considered this.
 
Well, a friend of mine was thinking about it. But, notice The mazdaspeed protege cars runs hotter engine bays I ever seen. So, thats an issue you will have to consider. You will not get all the efficiency that the intercooler may give.

I suggest if you are going to do that, to also make a custom job on the hood to move the heat out of the bay.

What about water intercooler?
 
It would fit perfectly right above my Injen intake, and I could utilize the DGM ram-air hood to allow cool air to flow over it.
 
the Subaru guys spend lots of time and effort to change their TOP Mount to a Front Mount because it isn't the most efficient method (between the two). I don't think there is much room under our hood to do it in a cost effect manner. Also....adding anything more on top of our motor decreases it's efficency to cool of (maybe marginal, but it adds up).
 
If you get rid of our little stock intercooler and put in a larger radiator, you increase the cooling efficiency of our car.

no room....too expensive to fabricate, not as efficient as a FMIC, you loose the sway bar....

hows thay have anything to do with the sway bar????.........maybe you'er talking about the STB?
 
But there is plenty of room there after you remove the stock air box and you install a cold air intake.
 
I'm not going to argue with you....but the bottom line is that it would be a very TRICK and Show Winning modification, but if you are looking to increase the overall cooling properties of your MSP, a TOP mounted intercooler is not the right route to take.

With the money spent on fabricating a TMIC and then calculating the Cooling Area/Surface ratio to dollars spent...it does not make sense. You will be very limited to the surface area you can expose to air vs. the amount of area (and depth) you can achieve with a FMIC.

If you want to be unique and have the money...more power to you...in fact it would be awesome to see! If you want to get the best performance and want to spend your hard earned dollars in the most cost effective way...then FMIC.

IMO
 
I agree and I am not trying to argue either, so please don't take anything the wrong way in that respect. I just believe there is some efficiency there to be had with the DGM ram-air hood and a top mount right over the intake.

Again I apologize if you thought I was arguing with you.
 
It won't fit... The plumbing alone will be a pain in the ass. Then you would have to find a hood that can accomidate the TMIC. I am sure the reason why subaru runs the TMIC is becuse the is no pressure loss to the intake mani. Subaru's use a Boxer engine so the intake mani and runners are right on top. This allows for direct cooling to mani. Subaru TMIC are very efficient. They are subject to ambiant air at all times due to the hood scoop. Most subaru guys don't not change to a front mount unless they are running a high hp / high boost motor where a TMIC can not flow as well.
 
TMIC is a good choice for boxster engine configure, because the engine isn't as tall. With our inline config. It would be pretty tall for a TMIC. Nonetheless the hood would have to be remodeled and remade. Not to mention that while the car is sitting, all the heat will "rise" up to the TMIC and possible heatsoak the IC.

Advantage of TMIC, is compact design and generally on an equally design FMIC, TMIC exhibits lower pressure loss, due to shorter piping length. Also, due to the shorter pipe length, the compressor doesn't have to pressurize a longer pipe length = faster boost to the cylinder = less boost threshold
 
I'm currently making a air to water intercooler but it's for my first gen protege with a gtx engine in it. I plan on using the stock a/c rad and a modified for water first gen talon intercooler, the batterie is going in the front of the car where the sotck airbox was(honda civic batterie it's the smallest i've found yet), i will use the space from the batterie to have my water tank with coil tubing in it for the fuel line also. I'm also planning a methanol reservoir in the water tank to get it really cold. The car is going throw many modification has it will be my 1/4 car, it already has been stripe of everything not usefull. I managed a 13.8 at 104mph since the weight reduction, on street tire.
