different v-mount!!!

I founf this on the other forum, I hope the owner won't mind. The intercooler at the bottom! I think it's a great setup






air splitter/duct



vented undertray

Great Setup!!

only thing is when he wants to flush the coolant, he will get it all over the intercooler!!

thats why they put the radiator on the bottom...

how does that perform? same as a very good v-mount setup, right? I think it looks sick, I love how the nose looks, after the install is done. so what are the numbers? I wonder? pics of the whole engine bay would be awesome, I am also interested in the intake? its real nice the more I look at it.

its a good setup in that he is mounting everything as low as possible

but for flow, the intercooler and radiator at too great an angle from the incoming flow, and hence he is probably only using at MAXIMUM half the core face ie 0 flow at the front, and full flow at the back

I'm w/ Andrew...the angle is too low. You'd want it a bit more vertical to use more of the core.

I'm curious how the vented undertray affects performance of not only the IC, but also the undertray itself. I'm also curious how well the air splitter in between the IC and radiator works, and how necessary it is?

me too. who is this guy? we have to get him on here and tell us how and why he did this sweet setup. neit_jnf can you get this guy to come on and explain? that would be awesome.

Looks like a lot of hard work. Don't get me wrong, it's beautiful and probably very fuctional. But for the amount of work and money, I'll just stick to my good ol' front mount and spend the money on something else

On one hand, mouning the radiator down low would be slightly better for handling, since it weighs more and it's best to keep weight as low as possible. On the other hand, if a rock hits the I/C and it leaks, that's not nearly as catastrophic as having a cracked radiator. Either way, the fabrication work looks very nice.

I disagree. He has a splitter to guide the air. thats my .02

the biggest problem i can see is high speed stability. instead of taking all the air and making it flow up over the car, it will push it under the car increasing. more air, greater densitiy --> bernoulli's principle.

regardless of this setup I have to say that Front mount and dropping the radiator is still the best for airflow

Way to draw intake air off of the radiator fan discharge...

I also don't like how low EVERYTHING is...oil coolers, intercooler, etc. Good for a track-only car, I guess.

I'd have to agree, although I wouldn't go as far as saying "at maxium half the core face" is being used. Much would depend on how much of a negative pressure area is developed on the exit side of the duct underneath, which is hard to tell without seeing it up close, along with the rest of the car (the splitter is a good idea, but not the end-all). Still, the angle is so sharp that the airflow going through both cores towards the rear will be painfully slow because the airflow has to make such a sharp turn. I'm not really that enthused about the setup.

that intake is in a very very deadly spot. air coming out of a 200 degree F radiator cant be healthy for you intake temps reguardless of how efficient your intercooler is. even with the splitters, he could make that v mount more efficient by making a greater angle because of the direction of the fins.

although thats one hell of a fabrication job..... well done

*edit* didnt realize that rynberg already stated what i said... sorry didnt read the second page when i posted

way to look at a 1/2 complete fab work and draw ur pompous conclusion. good work sherlock.

This is a terrible example of a vmount setup. You will not be seeing the full benefit of vmount by reversing the IC and radiator positions. By putting the radiator at the top, your intake will be sucking hotter air and all the hot air from the radiator will be heating up the engine just like the stock mount IC. The air existing the IC will always be cooler than that of the radiator because your radiator will stay at minimum 85C. But your IC will be at about 2-10C above ambient depending on the size of your IC core if you are running a standard vmount setup. The other benefit of putting the IC on the top will be cooling off the intake manifold and the rest of the engine because the air existing the IC is a lot cooler than that of the radiator. This is why people running the vmount IC sees much lower intake temps than those running stock mount IC or FMIC even if the IC core is the same size.

By using the same components and put the IC on the top like the rest of the vmount setups, you will see at least 5-10C cooler on air temp and it will not affect water temp at all. It will has less lag as well because the IC piping will not be as long.

i dont believe thats the main reason for putting the radiator on the bottom for the vmount

if you think about it the radiator and water would weigh more than the ic and air.

as for flow, all the flow would be towards the latter parts of the cores, ie !< (side with ! on it) this is because its the greatest pressure region

engine bay temps are always going to be high, the bonnet vent would help to reduce this; if you have a look there is a slot in the front bumper (although alittle too small) for the air intake, and the air out of the radiator should vent ok

Agreed! I can't believe people are glossing over this. it's drawing air from the highest pressure point on the car (front bumper) and forcing it out the bottom near the front axle!! This seems like a terrible idea.
