Hi guys.

I am wondering has anyone ever done a Z-mount IC and Radiator type thing?

The following way:

Flat mount Intercooler on top and the radiator put in an angle to the IC.

Also, The car has a Greddy FMIC, the large one. You think it'll fit? It's a little custom work, but I want a really WELL done circuit/AutoX car and I dont wanna go short on some things.

What do you think about cooling efficieny? will this help with lag?

haha. I found a pic of what I mean, this is a Sr20 though.

-efini-

THat looks like a lot of work...why? V-mount makes more sense than that...i dont know bro, looks like its just going for the "what the ****" factor.

well, ok. Looks pretty cool, but i dont think this is any better then an fmic. But the nice part seems to be that you dont have to run all kinds of tubes everywhere. If you had one of those reverse vented hoods with the vent right over the IC, i think this would work very well. This may not work very well for rotarys since the radiator is so big...
Whats going on with the top picture? was the camera man drunk? I dont understand why the picture is so crooked!

Yeah. That's more of a V mount. You can check J-rats thread on his vmount.

The one problem with that pic above is that both the radiator and IC will be fighting for the same air. It would need seperate ducting to make it good.

So, what should it look like?
I mean the car has the bog Greddy intercooler. Will the Radiator get sufficient air? Like I said, im not gonna do quarter mile, im gonna be hard on the car for several minutes at a time.
Vmount as in the radiator put in a V and the FMIC ahead. Do people make like plates or sometihng so the radiator can draw air from below?

sorry, new to this deal and havent even opened the hood yet, as it's not my car YET lol.

? wouldn't the intercooler get heat soak? it looks a top mount thats been relocated to me.

-efini-

^^ not really. Look at the size of that core...besides, with a vented hood, no way.

No I don't think you understand, the "V" IS the rad nd intercooler, there is no FMIC infront of it.

Most "V" mounts look more like wht you have in the picture then an actual V since underhood real estate comes at a high price.

This explains alot.


There are NUMEROUS members running a front mount with an upgraded intercooler and have no cooling issues. The biggest thing is that you have ducting in place to guide all the air THROUGH the rad and not let any escape around or underneath it.

Okay, I gotcha. I just wanna have ideas and plans. I love rotaries, I really do. Problem is i am only on the theoretical side and have never worked on one. I do know a couple of people with them though, hence my enjoyment of the rotary powered cars. but only FD, FC's are too scarce in Germany.
But I really want a clean nice look and everything done right you know.
So, is it possible to make the radiator vmount, or put it this way, put it in an angle. Are there kits for that. I think I have seen that. I would then maybe get some plates made to get air to it from below.

Isn't this just a Vmount with the intercooler not angled to get any air, I thuogh vmounts had a ">" look to them to get air flowing through the int and radiator in split directions to avoid overlapping them. I'm pretty new as well but this looks like any other Vmount to me.

Look up j-rats v-mount thread, as suggested. I think it will answer your questions.

classicauto

iTrader: (3)

Probably not, it will confuse them as his is really a backwards V with seperate ducts for I/C and rad.

The pic is what MOST V mounts tend to look like, trust me - there isn't a whole lot of room under there to have a huge angle on the I/C, otherwise the rad wil be flat or touching the ground.

Best thing would be to do a search for Vmount vs. front mount or soemthing along those lines. there ar numerous threads with decent discussion about benefits/downsides as well as setup discussion.

thanks classic, I was about to say I've seen J-rat's thread before and it is what gave me the idea of a Vmount looking like trhe one in this thread in the first place. I guess I'll just search, but wouldn't it take the same ammount of time for you guys to tell me how it is setup as it would to post "search"? Or is this some kind of learning a lesson thing?

J-Rat I believe tilted his radiator forward instead of back like this one. This is the true V-mount in the picture.

With a vented hood and a piece of metal to separate the airflows this is the BEST possible way to cool. True the radiator and IC are fighting for air, but its cool fresh air. Not air thats coming thru the backside of the intercooler and moving much more slowly when it hits the radiator. An electric fan will help keep it moving thru the radiator but its still warm/hot air.

If you split the airflow with a peice of sheet metal then they are no longer fighting for air and the e-fan on the radiator is pulling as much fresh air as it can from the available openings. I of course will be placing a fan on the bottom of the intercooler as well to push air thru the IC and out the vent in the hood.

My V-mount setup will be absolutely identical to this one except not using ARC stuff. They even have the oil cooler getting fresh air also. Thats the best damn setup I've ever seen.


I think BLUE TII has the best intercooler setup for a street car possible and its almost identical to this.

My setup won't come until fall or winter but I sure can't wait.

Lag vitualy does not exsist anymore wth modern BB turbos. You should get a small bump in boost threshold with a Vmount.

But I would say your FMIC you have now will be to big.

ok so the picture in this thread IS a v-mount? I'm confused. I did the search and I remember seeing a diagram a long time ago but I can't find it. All I can see is pic of an engine bay and I can't see the radiator. Someone show me a Vmount without a front bumper or something because this is bugging me. Soemone tell me without saying search.

these are V mounts I've done in the last few weeks for people, the S14 ( first one) showed remarkable improvemnt in response and cooling to the standard FMIC layout.. the fist one we did on this customers previous S13 was so efficent at cooling he had to take out the ducting and turn his rad fan off to keep the engine within the normal operating temps.




the second image is how I've layed out a V mount ( with the oil cooler below the rad in it's own air stream which I suppose you could call a 'Z' mount) in the FC.. LOTS of room to play with provided you size everything accordingly... it's not finished but I expect to be able to overcome any low end short falls in boost with this setup.

i dont see the greddy fiting at all
sell it and you can more than pay for a new smaller one and pocket some cash.

ok thanks, sorry to threadjack, back to looking and th efirst pretty pic

DarkKnightFC

You're the damn man. Thoses are beautiful setups. And everything you've said is exactly what I've imagined and pictured in my head for the longest time. I'm going to be doing all the work myself for the most part and substituting the aluminum piping for heatwrapped exhaust piping since I haven't the slightest idea how to weld. I would like to keep the project under $500 and we all know that can't be done if you're paying someone to do it. Thanks for those pics. If you have anymore I'd love for you to PM them to me.

I have a similar setup to that.

Not in a FC but thought that I would share...

I will post a few pictures so that you can see the entire setup.

IC core: 24"x12"x3"
Rad: custom 14"x20"x3"
Oil cooler: FC

And it hides the Turbo, when the IC is on it looks small...gotta love the sleeper.

Any particular reason you didn't run the pipe like this on this particular application? I know it might interfere with the can but you would move it to the place where the pipe was.

'87 turbo II

umm probably because that's where the turbo sucks in air, not pushes it out. I'm guessing that pipe goes unde rhte car to a fender ram air or the front and that turbo out just makes a little u-turn up to that intercooler.

Undutched

This is pretty much what im yearning after

I'll get rid of the Greddy and get something smaller, but i still want a quality piece and a big radiator.
Anything on how efficient your system runs in the FC?!?! or are you not that far yet?

DarkKnightFC

Good ******* point. Damn I wish I could see straight sometimes.
