V-mount? :)

I have decided to go v-mount fo rmy road-racing ventures with the track car.

Using my old Greddy RSPL IC (kinda crazy but it worked out), tried using my old Koyo, but its just too wide to be able to mount well without cutting anything, and i dont want to cut anything to keep tructural integrity up front.

My greddy piping will all have to be modified to get this to work, and a custom radaitor orderd once I sell my Koyo, or find a good enough deal on one with dimensions close enough to what i need.

So far all i have is the IC mounted up, pretty solid, but i knwo the IC piping and ducting will stiffen it all up even more, so thats not an issue.

more to come...

Looks great, but shouldn't the core be mounted at more of a V (so the top back is farther down) so air doesnt have to make a 90 degree bend to pass through the intercooler...just a thought. Also, are you going with a precut carbon hood or are you going to cut the oem hood?

if i angle the IC anymore ill have to cut the lower rad. support to get a good angle with the radiator, i refuse to cut things, just for structure reasons.

This setup is not for IC betterflow, the IC got more than enough flow mounted as FMIC, this is a setup to get more air to the radiator, for coolant cooling purposes.

If ducted enough/correctly, teh IC will haev tons of air moving through it, with all the forward movement and mass amounts of air forced through the mouth of the bumper, it has to go somewhere, either up through the IC or down through the rad. In teh end, coolant temps should drop, and air temps should stay around the same resulting in no powerloss.

no PS was really nice at the track. Got used to it on the street.

Without hte pump there its soomuch easier then with the belt just removed, after you get used ot it you build all kinds of lil muscles you didnt even know you had before.

I will end up going back to PS tho eventually, once i go with a much wider tire setup.......one of my many future tricks for you kids to see :).

I know how/why you go V-mount, but I was just asking because if the air has to make a sharp angle upward, then this will be like having a huge air-brake in the middle of your car. This MAY hinder your top speed or stablility at higher speeds. I was going to say this as a joke, but in all actuallity, I dont see why this would not work (I am not telling you your way isnt good, it looks awsome, just wanting to discuss ideas). Why not do a reverse V mount so the Radiator is on the top and Intercooler is on the bottom? You could possibly still use your old Koyo also. You could take the radiator and mount the lower section right next to the oilpan and the top on the radiator support (same as it always was) then put your intercooler with the bottom (so the inlet/outlet are close to the radiator) about 1/4 or so up from the bottom of the radiator and the top of the intercooler on the "nismo power brace" (Dont know what it is called stock). I honestly think this would work very well...just an idea though.

i have thought about going reverse, but if you think about fluid dynamis, the air will flow very well if ducted right, if you guide teh air properly, this whole setup should work perfectly, All the rx-7's, Signal drift cars (didnt wanan bring drift into this), and just about 85% of every other v-mount has a flat mount IC with radiator on the bottom, just for fitment. Itll cost me just as much to get a new custom radaitor as it would an IC, cause there is no way that IC is going to tuck down between teh frame rails...its HUGE :). Im going with the idea of "use what works", radaitor downlow and IC up top. I have faith that the air will flow through smoothly once its guided only throught the rad and up through the IC and then up out the hood...at a decent angle, should flow just fine.


looks nice....

dibs on the koyo
its ALL YOURS, i have a FS ad up on 4 forums, no grabs yet, so contact me about it we will work it out.


if you wanted more of an angle why not fab brackets to adjust the angle of the ic? Looks great though.... im very jealous.
Once everything is in there...nothign will be ablt to adjust, ducting will be installed for a perfect fit, and the radiator will come right up to the bottom of the IC. If i have more room to work with (smaller IC) would be a huge possibility, but i was trying to use what i already had, without cuttign anything on teh chassis.


radaitor situation will be workedout assuming a sale goes throught with Red

tubby: I wouldn't go through all this trouble simply to have your car be a sleeper, or even to *potentially* increase boost response. I would do it solely for airflow reasons, as it's a good deal of pain to go through for the other two. But if you want to do it regardless of the cost and time involved, go for it.

Those are what a v-mount looks like...yes tubby. THe bottom picture is kind of the reverse design usually associated with RX-7's, im only doing this for better cooling of the radiator. Its not something you want for a sleeper, might as well just paint you IC if you want it sleeper.

my setup will more closely resemble the upper picture, except my end tanks are not getting modified, im doing the most minimal of custom fabricating for this....brackets and ducting is it. no cutting of anythgin except the greddy pipes i have.

And just to put it out there...I will be ducting the IC up through the hood with an insert from the underside to have good airflow over the hood and up and out of the intercooler.

The angle on the piping for the cooler outlet to throttle looks like its gonna be fun :)
the angle actually matters?

as much as that sounds like a newb response, i did not know that.

I'm gunna have to take that angle stuf into concideration....eventully


and i didnt say anything about no AC since well, I don't have it either and its hot sometimes heh

the piping is completely possible......just need to be a lil creative with it...and itll be two pipes one for each side...no long pieces of rubber tubing either. When this is all done i am pulling everything out and redoingthe engine bay so itll all look nice and pretty for race season :)

I would not cut up your greddy piping. Sell it on ebay or in the for sale section. That should pay for a good amount of the custom intercooler and a set of universal pre bent intercooler pipes from summit or jcwhitney.

i know all the MA guys. They fixed a v-mount that Matt of Import Intelligence slapped togeather for some guy. The do cool work and some nice jobs. But frankly, no offense to Brian or Rey but i would much rather do my own work, none of them have actually done a v-mount before so its not my first source for information. They know im doin this setup, and when im all done Brian wants to see my setup to see how i put it togeather.

The only thing MA does that i personally cant do, is welding, because i dont have a good welder, brian and Rey are both great welders, but i have faith in my own work, no one else to blame that way. Sorry for the rant, but i enjoy doing my own work, fail or not, its a way of learning.

This setup will work perfectly fine.

Never thought to sell my greddy piping to make my own.....good idea, thank you very much TD5Turbo.
