Thank you!

asking a bunch of common folk as ourselves and with no testing equipment NO real information we can provide will be accurate....just IMHO right off the bat i dislike very much the look of an FC running the Front mount....those pipes are very distasteful IMO, next is since running a top mount is prone to heat soak and low cooling efficientcy....but shorter travel...and front mount cools the charge air well but the supposed lag from all the piping....and the blocking of the radiator....and next u have the V mount not as much piping as the front mount by a nice margin and not as prone to the heat soak of being ONTOP of the engine like a top mount...so its the middle man the only thing is to me...it take a semi skilled person with gumption to build a V mount as its not bolt on...its fab work with brackets and ducting.....i have seen a number of race cars using Vmount setup BUT...BUT...they are properly ducted and THAT is where the difference truly lies...despite airflow and turbulance NOT being that of water....blady blady blah....LOL

can someone give me a detailed step by step way to fit one of these because my engine is out of my car atm and im guessing it wud easier to work it all out with out the engine in there.... add me to msn if u can help out rednob_71@hotmail.com

Here's one way to do it. The piping from the turbo to the IC is pretty shitty, mainly because I can't weld. Otherwise I flip the turbo-side endtake to get rid of my little 360 there.

The original poster kept talking about the radiator not being fully used. He must not have been talking about a rotary. Last I checked, this was a contributing factor to so many 3rd gens blowing motors from the factory, rad was too small with poor flow.

I moved to the v-mount for ease of installation and unimpeded flow to my radiator. Proper ducting is a must with this setup, otherwise air would simply never go through the IC, just around it. If you look at my hood, you'll see I used the scoop from my old CF hood and used it to insure air would only move out through the v-mount, and not go around it when exiting through the hood.

I haven't checked the temp with a pyrometer for comparison, but I can say the tank where air is leaving the IC is much cooler than the opposing tank, to the touch. I'd personally like to get numbers for this, but temp sensors are expensive!

I saw a v-mount on JUN's impreza race car in a magazine, before I even really knew what drifting was. I don't think a comany like JUN would be using something that didn't work as well as... well, anything else.



well, I just got my car running, and I'm running a V-mount, on which the ducting hasn't been completely finished, and there's no hole in the hood. now, I haven't been pushing the car hard yet, but just driving around town on a 65 degree day, my coolant temps were staying around 185-190 and I never saw my intake temp rise above 85 degrees. these numbers were both shown by my haltech.... and my radiator is an undersized scirocco radiator(12x18" core and like 3" thick... although it is dual pass), and my fan only pulls 800cfm. lol. but it hasn't even thought about overheating yet.

anyway, I'll get some more numbers when I get it all dyno tuned and I can drive it hard.

so u dont have to move the oil cooler or radiator in a fc jsut the batter and shroud and mount the cooler and thats it?

DragonRx7

You have to move the radiator back to an angle to form a > shape. The oil cooler can stay where it's at but it's really up to you if you want to move it. And if you set up up better, you don't have to even move the battery. And then you need to make the bracing to hold up the radiator and intercooler at the new angles, new hoses for the radiator, electric fan, ducting to direct the air and seal off the sides of the > and some other small things that I'm probably forgetting off the top of my head.

Be careful on what you're trying to imply.
Car shops like to push **** to make money, period.



Are you talking about boost?
How much boost?
What size turbo?
If you can get the temps to stay under 115F under 15psi of boost, I'd be impressed.

true, but I think when a company is trying to build a car with the intent to get the fastest lap at tsukuba circuit, they're going to be a little more worried about the cars max performance, than just trying to sell a new item.


I will try and do some datalogging at the dyno tomorrow. I'm planning on running about 14psi on the stock turbo.

^an 800 cfm fan? Your in big trouble once summer hits..... You need atleast 2500+cfm.

The common location for a FMIC in FC's is a foot or two in front of the radiator and oil cooler.
Leaving a large gap between the IC exit and the Rad entrance isn't good for flow. That's where most cooling problems come from IMO.


I am planning on changing IC's soon and have decided that even though a Vmount would be fun to do it's too much work.
I will go FMIC but I won't place it in the common location.
I will place it in the location of the AC condesor. Just an inch or so from the radiator

This should keep the flow restrictions down to a minimum since there won't be a void for the air to float around in.

Bigretardhead

yeah, thats what I thought too. the only reason I got this fan is cuz I needed something fast... but its doing fantastic so far, so I'm just gonna use it till it doesn't work good enough anymore.

Just be careful. It only takes one time to all of a sudden need a rebuild.

Bigretardhead

yeah, I know. I'm gonna go ahead and get a bigger radiator, and fan now. it starting to get a little warm, as I expected.

but at the dyno I was showing about 110 degree air temps at idle, and they actually went down to about 103 degrees under full boost (13-14psi, which was like 9psi according to the haltech, I guess cuz its reading ambient, and I'm at 5500 ft elevation).

Your just jealous

The second pic was taken umm well before i added **** for airflow. . .

Uh, jealous about what?
That you cut out the stock front bumper?
