custom v mount
 

I came up with this idea when I was looking for a good v-mount. The thought is to take 2 stock tmic and cut to end caps off and weld or epoxy them together. I used some heavy duty paint stripper. They stll need some work but you get the idea.

Here are some pics.

thats something we used to do 15 years ago when intercoolers where hideously expensive

now they are not,, and even china types will do a better job with less pressure drop

you have the serial pressure drop of 2 stock intercoolers,, which where not known for being free flowing already


when you go V mount,,, you win something,,,, AREA
AREA is what indy and many china coolers are about,, they use AREA to get thermally efficient
the reason they need AREA is that they are not restrictive inside,,,they are not as efficient at transfering heat to the core internally as more restrictive types

the idea is here you get the cooling you need ( due to area ) without crippling pressure drop

if you make a V mount and use two serial stock I/C you are not making the best out of the oppurtunity provided by the V situation

go the china style/ indy bar and plate cooler,, they can be had very cheaply
and i have seen them make excess of 500 rwhp and without huge drop across the core like some very expensive tube fin styles

If your trying to do this to save money, then a vmount is not for you. Plain and simple.

Look into chopping those two tmic's together to make a 50% larger oem tmic.

why does the v mount have to be expensive? I can fab 95% of the work.

a 50% larger tmic though a stock hood in Ga. heat is no good.

as for the pressure drop how much are w talking.

its easy enough to measure if you use a pair of boost gauges , a couple of tees a couple of one way valves and a couple of rack solenoids
you rig a system that will make the gauges peak hold via the one way valve and open when 12v is enabled to the solenoid ( teed around the one way valve )
you hook one gauge off the turbo discharge ( usually teed off the wastegate hose )
and another on engine side of TB

drive the car with the solenoids turned off and each gauge will record the peak boost settings
( as long as the BOV is functional and you dont let off the peddle quickly while driving it will be acurate enough for this purpose )


from what i have seen , expect 6 + psi above when 15 psi is seen at engine -while other coolers will do it with less , good ones less than 2 psi
21 psi while on a target for 15 psi is a lot of boost the turbo has to do,, even pushing some out of the efficient map zones

i have seen around 350 rwhp on a ballooning stock intercooler pushed beyond reasonable limits

and doubled ones will make LESS on the same turbo

most of the guys with twinned units and highflows back in the day where limited to less than 300 rwhp

ok... a 6 psi drop is way to much. a china one do yu have a link? i found one on ebay form cxracing for about 100.

Btw. yes I want to save money but this is not a DD so I'm not rushed to get it in and done.

cxracing sells decent things. I have there rad and intercooler.

well, you mentioned epoxy which to me points to extemely cheap and will not hold anyways.

epoxy doesn't always say cheap. some people use Jb weld for everything yes and that is cheap. the stuff i was thinking of using i have personly seen it hold up to 60 psi on air and water. also there are epoxys out there that cost more than a avarage welder makes. (on a job like this that is)

you can get a vmount for $60

you can get a vmount for $60

you got a link i would jump all over 60

Id love to know where you're buying.

I fixed it for you. ;)

i can only assume he means an Evo stock used intercooler, which still involves more than just getting lucky enough to find the core for $60.

True statement.
I have a custom v mount that uses an evo core. It works quite well, but the pipes coming off the core need to be cut and re welded in a more friendly position. Of course you also need to figure or how to mount the rad and if you aren't creative you'll need to remount the oil cooler and/or extend the lines. Keeping ac and ps presents yet another challenge.
