I've been thinking about moving my intercooler into the engine bay to reduce the amount of piping that is used when having it behind the front bumper. This is not really a V mount. I'm looking to place the intercooler in front of the radiator. Anyone have experience with short intercooler piping? Is the response much better? Was it worth the effort?

and how are you planning on getting properly working and efficient cooling system if u block the radiator? theres no need to bother unless u doing a v mount

and having a front mount in the bumper isn't blocking the radiator??? its possible bro and is actually a decent idea. the radiator fan will be able to suck air to even possibly help cool the ic its self. what i was gonna do was run a shorter ic n cut the chassis a little bit n run the ic pipes right around the radiator. instead of running it around then up then over.

works fine
my friend has it
actually 3 of them do: doriftoslut, flybert and maeda all do. SR, SR, KAT
response is nice,yes noticeable from the FMIC location that is most common to most.
all s13s, he has it upside down infront of radiator
water temps went up..slightly, talking few degrees C max
most problem comes at full stops i ntraffic and hot weather
but overall, driving, next ot no change.
on the track, does fine
also good if you track the car, less chance of crushing your intercooler/piping at teh track. more protected
420sx has no expirience. dont mind him.
do it!
ill have smae on my s14 when i do some other upgrades.

WTF mate?? You do know how automotive radiators work right? Also V mount set ups are nothing more than shitty gimmicks, used to show off fab skills.

aparently you dont know eather. ( FYI its mostly using arodynamics to help keep the car on the ground and creating higher flow of air over the IC )
this thread is useless without pics.. so here they are

basicly with the amount of heat change coming off the IC.. its like its 10 degrees hotter outside on a stock car.. so not realy anything to worry about.
spool is crasy quick. I have a lbs or 2 of boost at 1k rpm 10psi by 1700. (gt28R)

holy time for a new radiator hose batman. that looks kinked in all kinds of ways I never thought existed. thats actually not a bad idea. Air is going to flow from the IC to the radiator anyways so I cant see it being THAT much of an issue. This might make IC piping VERY nice :-) got me thinking....hmmmmmm..... lol

dude fab a shroud quick with something... aluminum sheetmetal, fiberglass, same kinda material is stock... something.... that gap will help cooling if you block it of with a shroud...

agreed shrouds are DEF a needed thing in that setup.... I might do the same thing now with mine lol. Mount the IC upside down and in there for much shorter piping :) Why hasnt anyone done this more often???

Yeah v mounts are poopy nothing that the set up of 3rd gen rx7's was basically a "v-mount". I think that the idea is great in theory, the problem is MOST people dont do it right and it sketches me out. If you think it through and do it as proper as possible I give you a thumbs up. The current set up I want to do is just have the part where the intercooler piping connects(I dont know the proper term) to the intercooler at the top of the end tanks compared to the bottom. This wouldnt be placing it directly in front of the radiator, and could have some clearence issues but I think its a good idea. I'm also describing it terrible since there are many issues to worry about with this. Just do everything proper and I say its worth. Just remember, the reponse will be better, but not the spool time. Some people get that confused

thats the same exact ic setup i've been planning. but never thought about jus tilting the radiator back like that to do so... great idea and good job. way better then ruining a bumper support n bumper and use twice as much piping haha. i wanna go home n do mine now

Here's my car.
Pop up healight motors removed and headlights braced in the upright position. Also, hood latch support removed and latch, along with the headlights bracing is welded to the backside of the bumper support. (Nothing blocking flow to radiator or IC)

I hope your upper radiator hose has changed also... that one looks a little... kinked.

Thanks for the feedback guys. I'll be starting this project soon. I've found that on my current setup (Blitz LM), I have ~6ft worth of pipe and can cut it down to ~3ft with the short intercooler piping method.

hmmm..... i think i might try this...
there are two volvo I/C's sitting at the junkyard, just calling my name now :)

the upper hose is still the same, the pics make it look horable.. its only slightly twisted so the hose doesnt sit on the cold pipe. I am not worried about it at all.. will redo it with a new radiator.
as far as the shrowd, I would love one.. been dreaming of one for a while now.. but I have enough problems finding a place to change my oil never mind fab up a shrowd. but its on the list of things to do.

Apparently I know enough to not kink any coolant hoses in my car. I also know that to get proper airflow you have to channel it and not just rely on aerodynamics like you are doing.
And FYI, I never said that throwing an IC infront of the radiator is bad, hell there are a million things infront of the radiator that disturbs "flow of air" like the a/c condenser and the fans. My main gripe is v mount set ups.

all i know that when i was doing the swap on my friends s13 we put the greddy core right in front of the radiator and we had a problem of overheating even with twice as thick radiator core didnt have the piping so it was made shorter. its ok when ur driving but not in the city/town traffic so we had to do move it out furher.
plus i just dont see to do that amount of work for a lil better responce. if u did it right away then ok. might as well do a v mount. pfft that lil bit of space in between does help for cooling. once its too close theres a problem imo. thats why i said it dont cool than well. its as simple as that.
plus^ a/c condesor got to go heheh. you dont need a/c. :kiss:

i know a guy who runs a 400hp sr with the intercooler mounted in the radiator support, his newest project is a front mount... depends on what you want out of it

now now childred settle down no fighting lets actually intelligently discuss it. this is an interesting idea and im surprised this is the first im hearing about it. I can see this as something that will actually help things. this will increase response AND spool however. The biggest impact on spool is internal volume before the turbo. its a pressure tank and you have to build pressure to spin it up. however the same applies to the area after your turbo. theres a certain cubic foot size after the turbo of piping, intercooler, etc. before you can have 1 psi of boost you have to be able to meet the cfm needs of the engine and provide enough air to occupy that space before it (plus some). a turbo drives a certain amount of air and it can either be stuffed right into the engine or to occupy those huge intercooler pipes. more air and more fuel make more exhaust meaning more spool so technically this is more of a boost response mod but will in turn make an impact on spool time as well.
as far as negatives go the intercooler is right in front of the radiator ANYWAYS so airflow wise it shouldnt make that much of a negative impact on the radiator. I can see temps being higher due to heat soak radiation since they are so close to each other. This would make more of an impact at a still than while moving. Radiator fan will also help cool the intercooler too instead of drawing surrounding air however so this can help. Car would reach operating temperature quicker

cwdmark on FA did this and reported no quicker spool but response was better. There is a thread over there about the same thing with some different pics if interested.

Yeah, he dyno tested it as well and no increase in spool. So thats kind of like proof isnt it?

aparently you didnt read my reply. the hose isnt kinked at all. and if you read I never said anything about useing aerodynamics with my setup. just made coments about why the lamans cars and other race cars do.
but anyway back on topic tastyratz you are very right. the big point of the whole setup is decreasing the volume, and bends of the system.
I also think the change in spool would be so small becouse of the rate that the turbo pumps out air. I personly found a difrence when I was useing a small turbo, I had a little less drop off at the high end of things just becouse it didnt have to keep as much volume pressuized. but I doubt its enought of a change to realy waist documenting.

quick question... with your radiator moved back, and the intercooler in front, can you still have your a/c condenser? or are you guys running no a/c

Ohhhh I'm sorry I couldn't read your mind, you were talking about lemans cars. Wow and here I am thinking we were talking about slightly normal cars.

all of us I beleave arnt running a A/C. I guess ya could fit it all. would require a decent amount more work moving everything back and geting all the lines for the AC to line up.
