V-Mount Intercoolers

[driftex]

i'm looking for people who have fabricated/installed v mount intercoolers. let me know everything. I know how and why they are set up, but dont know too many specifics. basically just tell me everything you know.

[ZoltecRules]

Check out the Drifter Twins from Signal Auto, thats a good start:

thanks, but i was looking for more of a technical view, i've seen plenty, i just dont really know the set up. like where are the intercooler and radiator mounted, what kind of modifications have to be done etc. thanks any way

Well, just looking at my 240sx, I guess the best way to start it would to be to notch the radiator supports. However, I think you'll need to reenforce the setup somehow or your chassis might be weakend?

[driftex]

what about mounting the radiator and intercooler?

[ZoltecRules]

I found this as a pretty good post to look at:

You have to understand that this is not a very common thing for just a backyard mechanic to do. Typically this is done with some serious engineering by a lot of people. Companies that have done it (Yashio Factory, Signal, Rotary Extreme) have put a lot of R & D and engineering time into it. If you can devise a way to do it, then go you. But after you do it you could probably make some money off of it. (You'll probably need a mechanical engineering degree, like your truly ) You're best bet though is to go to those companies and ask them to set it up themselves. It might cost more, but you'll know it works.

thanks man, where did you go to get your engineering degree?

i hope that this V-mount setup isn't going to be on a daily driver seeing that you're going to overheat the car the first serious traffic jam you get stuck in

it would be a daily driver but i would be driving it on the streets on weekends to races and/or track events, i wouldnt be using it as a comuter car. where do you mount the radiator and intercooler?

honestly....the questions you are asking are very basic which show a lack of understanding of a V-mount intercooler setup and the reasons as to why somebody would install one on their car.....you shouldo do considerably more research on this subject prior to deciding 100% that you are going to install a V-mount setup

the intercooler and radiator form a V with the radiator on the bottom and the intercooler on the top....hence the name V-mount.....the reason people do this is b/c is provides better cooling for that radiator as opposed to the traditional FMIC setup......the hood needs to be vented right at the intercooler and you need to design the proper shroud setup to go around the intercooler so that the air doesn't just go around the intercooler rather it goes through the intercooler.....there is a lot of work involved in this....you're going to have to fabricate all custom tubes for the radiator to the thermostat since hoses won't cut it anymore...you're going to have to custom fabricate all of the intercooler piping.....and it isn't as easy as just getting the pipes with the right bend in them.....if you find close up pics of the signal auto drift twins you'll see all of their piping is welded rather than just mandrel bent....you're going to have to do that to test fit everything......make custom bracketry for the radiator and intercooler.......and there is even more involved than that

and the reason i said you shouldn't run this on anything but a track only car is b/c when you're sitting at a light there isn't any air moving through the radiator and you're going to end up frying your engine.....i've known people who would over heat if they had to come to a complete stand still for too long of a period b/c there just wasn't enough air going through the radiator.....and on top of that they would heat sink their engine b/c there was insuficient air flowing through the intercooler.....and electric fans won't cut it enough b/c then when you get up to speed they'll just hinder the air flow

do yourself the favor and if you REALLY have your heart set on a V-mount setup just call one of the japanese tuners and have them make the setup for you......even if it costs more money than doing it yourself at least you'll know that everything on it is going to work and fit

Bradley University in Peoria, IL, Mechancial Engineering.

This would be a fun project to do in Pro/Engineer, anyone else besides me know this program?

Not to be a jerk or anything but i already knew all the things you just said. i basic just dont know the specifics like mounting points for radiator and intercooler.

and the reason i said you shouldn't run this on anything but a track only car is b/c when you're sitting at a light there isn't any air moving through the radiator and you're going to end up frying your engine.....i've known people who would over heat if they had to come to a complete stand still for too long of a period b/c there just wasn't enough air going through the radiator.....and on top of that they would heat sink their engine b/c there was insuficient air flowing through the intercooler.....and electric fans won't cut it enough b/c then when you get up to speed they'll just hinder the air flow

most of this stuff was new to me, so thanks. i started this thread mostly just to gain information about v mounts, incase i ever do want to do one. i was cosidering one now, but the thought of heat sink totally slipped my mind. i was too focused on how cool it would be.
thanks, didnt mean to piss you off

no no you didn't piss me off......sorry if it came off like that ....it just seemed like you were all set on doing a V mount setup but didn't really understand the use for a V mount that's all

i'm glad I was able to help you better understand how they work and why people use them......don't get me wrong.....i would love a V mount setup so when you open the hood people just drop their jaws ......but for a car that is driven on the street it isn't the most practical idea......people do it....i just don't think that i'm going to be one of them

Not wanting to start a fight or anything, but you are a little wrong with your description of the V-mount. He could, not saying he should, but could run a v-mount on a daily driver because if you have seen a complete v-mount built and put together, you will also note that it too, just as the OEM radiator set-up has a fan. In the case of a V-mount, he would run an electric fan, Flex-a-lite's BLACK MAGIC has been proven to flow the most, on the bottom of the radiator, thus pulling the "non-moving air" into a moving state and crossing over the radiator and being pushed to the ground under the car. For a California car, I would definitely not recommend this, but basically if you know the traffic patterns of the city or town you are in, you should be able to make an educated decision. Again, not starting arguments, I just saw a flaw. I'm not saying I am 100% correct, but I know that most guys will put e-fans on their cars v-mount or FMIC.

if you wanted to get really nutty, you could fabricate a radiator shroud to work for both of them, and then give each of them there own e-fan, kinda overkill, but ya.

i would highly advise against this for a dd if your in cali, youll get owned buy police iunstantly if they pop your hood.

there was this really gnarly car at d1, the intercooler was angled like in a vmount, but the radiator was in the trunk, with its own fans and airflow, the engine was moved back about 6 or so inches and the firewall had to be cut, that car was really gnar....

[superstock2]

wow, i'm assuming that you drive an fc so a v-mount as a daily driver would be fine. i would like know why he would overheat in a traffic jam realsilvia??? the fc has a top mount intercooler from the factory and it doestn't overheat in traffic???? whats the deal?? why couldn't he run an electric fan on his radiator? plus he won't have to do any modifications to the frame/supports because the fc's have plenty of space under the engine bay once the clutch fan is removed. but yes the hood would have to be vented. the v-mount can be seen as the optimum intercooling setup. because hot air leaves out the top of the hood instead of passing through the rad...and becaust it doesn't heatsoak as easily as a top mount... plus pressure isn't as effected as it is with a front mount and the short pipe length provides good response.

heres a link to probably one of the cleanest fc's you'll evver see. oh yeah its a v-mount daily driver!!

yeah Matt i saw that car at GT Live.....that thing was a monster....i couldn't get over it.....i just kept walking around the car in circles

Jay....i understand your point but I have talked to a number of different people about V mount setups......and they have all told me that even with fans it can get kinda hairy in traffic......plus there's the whole heat soak issue to contend with.......i understand you're point and i know that people do run fans on their rads but i still wouldn't recommend this unless you lived in the sticks and never drove your car into the city

Daniel,

I used to daily drive my FD with a Rotary Extreme Vmount IC setup. I drove everyday in nasty traffic on the east coast and never once had a problem. Also, heatsoak is not an issue with the Vmount if you have a vented hood. Granted the IC will get hot while you're sitting in traffic, but once you start driving it cools off immediately. As far as the radiator setup, my engine temps never got as high as they did with the stock IC and radiator setup. I was running the equivalent of a Koyo aluminum radiator with a black magic fan mounted behind it. I'm currently working on a Vmount setup for my FC drift car.

Driftex,

If you want a Vmount setup for your FC then check out FEED if you want a prebuilt kit. It's going to be crazy expensive but it's very well worth the money. Or you can be like me and fab your own. I'm using a griffin aluminum radiator and the rotary extreme IC core. It isn't going to be all that difficult and I can promise that it will work like a champ. Just remember that you NEED a vented hood to take full advantage of a Vmount setup. Best of luck and PM me if you have any questions.

well we did an angle mounted IC on the AE86 Levin, but because its a track car we basically relocated the radiator to the back of the car (just behind the rear diff) and then fabricated some mounts for the IC using 1cm thick aluminimu rods bent to fit, which was welded to the supports and then some mild steel piping bent to connect the CA18DET to the IC. We then mounted two fans behind it and made a vent in the bonnet to move the hot air over the car instead of the engine bay.

It flows really well while moving, but sucks arse when stationary, which is fine by us since its not gonna see public roads.

In my opinion a good bar and plate FMIC with a decent core size and good flow is more efficient than a V mount or H mount IC of similar specs in a road driven car. Just like GT wings are useful on track cars but not on a road car

[realSILVIA]

That's interesting Zach that even on a rotary which are infamous for their ease of overheating and you haven't overheated with a V mount setup......i'm not going to say 100% that its not going to work well on a street driven car.....i'm just not going to personally condone the use of a V mount setup

believe me.....if there was any way for it to be just as efficient if not more efficient than a good core and radiator on a street driven car then i would be rocking a V mount.....they are oh so hot

pie cut and TIG weld and the right hood

BONNET!! WHATS A BONNET? get out of here you crazy person!


just kidding, thanks for the info man.

My bad... "hood" for you USDMers

umm i think your talkign about the weld s14, its in the newest modifeid magazine, cars built insane but neesd to be lowered, too mcuh wheel gap with the 17s, put some 18s

[S13/R32]

i don't really kno wat a v mount is but i installed my intercooler infront of my radiator leaning forwards away from the radiator which creates a v shape and some electric fans seeing i did away with the fan on the sr20detplus i got a GT-R radiator and a pretty big vent which pretty much keeps the radiator cool. don't exactly kno wat setup i ve got or kno wat its called but i put sum thought into it. plus theres a couple ducts so that the air circlates around the engine bay. and from wat i kno drifters only put there intercoolers in the engine bay so the first thing they hit isn't there intercooler which would take em outta the comp
