Default "V" Top Mount Intercooler and Radiator Set-Up

Any opinions on this kind of set up? What was the results?

not really worth the hassle, pros are apparent better spool/response due to shorter piping. cons are you have to run a fugly vented hood.

now for my 2 cents:
-IMO, thats not the ideal way to V mount. the radiator should be angled outwards, so the air passes into the bumper opening, through the radiator and fans, then up through the intercooler core, and out the hood vent. the picture posted i've seen many times, but i question how the air coming in the bumper and the hood vent pulling some of the air out through the top and the intercooler, how it actually manages to cool the radiator well enough being that its just kinda brushing the top...though the fans help pull some through, but it just isnt in the direct path of the air. the air seems to just pass parallel to the surface of the radiator. i dunno, it might work, but probably not as well as the "outward" Vmount setup.
-without proper ducting and sealing, it's nothing more than a fancy 'look at me' mod.


i guess it's good if you live in california and want to hide your ic and your modded car from the nazi smog patrol or cops or something, but i dont see the point in so much effort for so little functional gain other than the large (might be important to some) aesthetically pleasing look (see: JDM tiiite yo). if you want to hide the FMIC, just mount it between the a/c condenser and radiator (in that space)..that will also provide the shorter piping and stealthy look.

The key in the setup in the pic is the radiator fan. You don't need ANY air through the bumper directed towards the radiator if you don't mind having the e-fans on all the time.

Also Dan, your proposed setup is flawed because the intercooler would be blasted with 200*+ air from the radiator. With the e-fans on in my brother's traditional setup, we can get the IC temp down to ambient. In the winter, that's pretty low. One of the neatest setups I've seen is one of the late model WRC WRX rally cars.

The pic posted above needs a lot more ducting going on, plus the hood needs to be better than some hack job. Unless they have a man-sized top vent, it looks like most of the air will bypass both the IC and rad, and go right out the bottom of the car. Also note that it's basically impossible to run AC with a V-mount.

To relate this to the Skyline front'd S14 thread, the additional length of the Skyline front would make packaging a V-mount a lot easier. Just looking at that pic above, he almost didn't need to cut anything.

I agree with epstein. Looking at that picture, it looks like an incomplete project. It gets style points, but im sure it has pretty low efficiency for both the radiator and intercooler. They need some kind of shroud to direct air into both of those. The radiator sitting at an angle like that is going to provide alot of restriction, not to mention the intercooler sitting almost completely against flow. I'm sure their brakes will stay cool though ;P

Its how the vetts run their radiators i dont see an issue with it. add some Sheet metal Above and on the sides of the radiator and call it a day.

I've only seen 2 setups that i know worked well. Taylors on his old KA-T, and 1SICKZ (red 300zx in orlando that has like 670rwhp). It's a different approach, but i'd have to see temperature figures at different speeds to see if its a "better" set up, because i've seen tons of standard set ups cool just fine.

661hp. and i don`t remember him moving the rad from the stock location, which is slanted to the front. if he did the change would be to a vertical mount rad to make more room for a vert mount i/c up front. but like i said, only seen his motor once at the last zfest.

That is what I really like about this set up. Most of the v mount set ups I've seen they hack the radiator support and that's just not something I wanted to do on on my street car. It does look like a good foundation because ducting isn't that hard to make.
