intercooler tech. (hks to4r)
 

So im starting to put my hks to4r kit together and I dont know if i should go with a greaddy 3row a 2row or apex-i single turbo bar and plate intercooler I was just wanting some opinons or facts
thanks in advance --Arron

Go greddy 3 row

why do you say that?

i like the apex front mount.it would be good for you

whas the resoning behind your desisions?

actually I am starting to be a bigger fan of the vmount setup. I am getting tired of 200 plus degree temps on the highway.

If your FMIC is ducted properly you shouldn't be seeing such high temps.

there isn't enough air go thrugh to cool down the radiator so the vmount set up is the best on the market right now.

actually an air to water setup using the AC to coil the water would be the best

you think the AC would do a better job than a large heat exchanger if you were say....on a road course or something similar where you are staying in the boost for long periods of time?

The amout of BTU's you have to exchange is huge, much much more than cooling the inside of your car. I dont know that the AC system could handle it in a situation like a road course. It addition you'd need to somehow rewire the AC because it shuts off at about 40% throttle. How would you work it out if you wanted to have AC in the car? The IC would heat it up. Even if you could get it to work so that you could get air in the car what would you do in the winter would that ac have to remain on and blowing into the car?

I dont know that I'd say a air/water with the water being cooled by the AC would be the best. Why dont you set it all up and test it out. I'd be interested to see how well it works

Actually there is enough air flow, I'm running perfectly normal temps with stock ducting, a GReddy FMIC, and a Koyo radiator.

dont you have to have a hole in the hood for a v mount to work correctly?

There are pros and cons to both. The greddy FMIC you have to modify and cut your frotn bumper and also it's harder and more time consuming to install, whereas the apex'i is easier to install because the IC sits behind the front bumper support.

Performance wise I'm not sure which IC would work better. I assume the apex'i one will be better for your water temps because the IC sits behind the bumper support allowing more air to the radiator but the greddy one will probably cool your air intake temperatures better.

v mount man

i love mine

Bukwild- i agree with ya man i was get really hi temps with my apexi fmic w/ koyo rad

its koo cuz i have a vmount now and doin a to4s swap, so im all good

GL on the search for ic's man

i think the vmount is the way to go right now. fmic works well, but the elevated temps arent something to brag about. my car doesnt overheat, but it surely doesnt run as cool.

also, the vmount doesnt cause you to have to modify the front bumper like the fmic does. . . thats something i dont really care to do. . . cause you can mess up a nice bumper really fast!!!

so what about the V mount? does it really work better than a front mount? if so what has to be done to install one?

well with my greddy kit it ran so hot on the highway I had to go back to the stock rad and clutch fan. This summer I am going to try a mazda racing rad and vintage air efan and that doesn't get it done I will get a smaller intercooler and vmount it. Might try a dual FC oil cooler setup as well

Air to water IC
 

I have the Greddy IC with the mazda comp radiator.I then had plates welded to sides of the IC with spacing and bungs. I run a extremly large copper radiator with a Ford Lighting I.C. waterpump to my filler tank . Awsome low under hood temps and my engine temps dont go above normal even when testing road course.
Fast Freddy did this 1st and boost temps were around 100' on 98 ' day in LA.
I have had this for a year on a TO4E but will have the TO4R on in a few weeks.

so what has to be done for a v mount??????

so what do all these guys run that are pushing 600-700+hp? and how do they keep temps down?

you can just buy a v-mount kit either from HKS or from rotaryextreme. The IC and radiator is mounted in a "V" shape and both kits come with the hardware necessary for bolt ons. You get the benefits of having air directly channeled to both the intercooler and radiator. The only drawback is the price.... go to chucks website for more information www.rotaryextreme.com

so does the air flow well to the v mount style intercooler? what are intake temps of a v mount compared to front mount?

pretty much. . . a vmic is the same as an fmic. they both get a fresh unheated air source from the front of the car. . . and there is nothing to heatsoak either one of them. the benefit of the vmount. . . which is what i wish i had done. . . is that BOTH the radiator and intercooler get fresh air to them with minimal chances of heatsoaking, and there should be less pressure drop across the board with a vmount due to the minimalization of intake tubing.

paul

so which one will provide colder intake temps?

i would assume an fmic would do that job for you. . . since ALL the air going through that hole has to pass through the fmic. the air somewhat forced through the intercooler that way. . . instead of being able to choose the path of least resistance with a vmount. of course, you can always use water injection.
