Any body ever do a V-mount IC?

[aaronmatusz]

What I do with my car:
I like to attend track days and auto-x events.
I don't like race gas, meth injection, NOS or any other expensive crap I need to refill all the time.

The problem:
My big Dejon SMIC heat soaks at around 15psi on most days and I really don't want an FMIC. I already tried that and burned every last drop of coolant out of the motor due to blocking flow to the radiator... I should mention that my cooling system is much improved from those days, but still...me no likey front mounts.

So the big question is: Has a v-mount IC ever found it's way onto a DSM?

Pulling back from the wayback machine (aka memory). Greg Collier: http://www.dsmtuners.com/forums/road-course-autocross/210879-getting-ready-2006-race-season-4.html

He starts the discussion on page 3 but it goes on for a while. It worked well for him.

Here is a pic of the ducting he did for his pseudo vmount:

The issues of placement and general lack of space are the biggest concern for me. I too am an Anti-FMIC die hard. I have resorted to water injection and a custom side mount.

We have made several V-mount setups for rx7s (2nd and 3rd gen) as well as a 240. The major difference with those projects is the vast amount of empty space that is available between the radiator and block that is normally occupied by the stock clutch fan. With these we were able to avoid too much hacking of the factory bumper cover...

In the case of these cars most of the space available will be in-front of the factory radiator mounts. It may be possible but it wont be easy. I will be very interested in what you come up with. I am going to look into our evo counter parts to see what they have come up with.

i know it has been discussed before but something i was considering was a liquid/air heat exchanger... unless it isn’t allowed in the class of racing you do.

W2A intercooling systems are less efficient dude to the greater number of heat transfers required to cool the whole system. they do have some advantages, but are generally better suited to drag racers or autox cars that can take advantage of an ice cooling box rather than an additional radiator.

If a W2A system were to use a heat exchanger, which it would have to be in order to go road racing, It will still block flow to the radiator. Defeating the OP original objectives.

Here are some pics of what I have to work with right now:

The splitter is three inches lower than the bottom of the radiator brace.
I was thinking of getting a 6"Hx4.5"Dx24"W IC core to put down on the splitter and cut out the 'ramp' leading up to the radiator brace to allow air flow under the radiator.

Dotted line: cutting away the ramp. Xs: location for IC core.

It's not a V-mount, but it's the best I have come up with so far. Am I making sense so far?

wow a very interesting setup!

I assume the factory crashbar can not be replaced in whatever class you in.

A point to think about with that current idea. The thicker intercooler core will be less efficient as it gets deeper. we have these space issues commonly in the MR2 crowd where FMIC is not an option. you often get 5-6 inch thick SMICs. the problem is the back half of the core is only getting hot air from the front half. Basically a 1 inch thick IC of the same total volume would be a much better heat exchanger. I understand the lack of space, this is just some food for thought.

what may be a solution would be move the bottom of the radiator to the front point of the IC in the proposed drawing tilting it back so it just clears the bottom rad support then placing the same IC core above the radiator and ducting its exhaust Directly to the vent in your hood taking Full advantage of that massive pressure differential.

I don't have a good reason for this, but I've always tried to keep things reversible.
I guess I'm afraid my idea will be half baked and I'll wreck something real good.
I don't even know what the Street Modified class rules are in this regard, I'll have to check. I will say that I still drive this beast on the street quite a bit, so a crash beam is nice.


It's a good sounding idea endeffect0, I'll post some pics of a body shell I have that I can hack on.
Maybe I can mock something up soon.

Update time!
I've modified the splitter as per my drawings and here;s what it looks like:

OP, when you used a FMIC a long time back and over heated by the sound of it horribly. Did you happen to have ducting connecting the FMIC and radiator?

 

[aaronmatusz]

No, I didn't know anything about proper ducting until sometime after I went to the big side mount.
Then came the aero experimentation that became the "critter splitter".
This IC setup comes from a desire to keep using the splitter to best effect.

Edit: some more pics.

Op amazing lookin front end. Looks like its coming along greay... Any recent updates?

 

[aaronmatusz]

I've been having phantom knock issues during my last tuning attempt (turns out I had a boost leak, a badly leaking exhaust mani gasket and bad fuel.) Even so, the IC out was cool to the touch on the dyno and water temps stayed under 190 deg. I'd say this setup is working pretty good.

I may have more news later this week.

Update:
Measuring from the compressor outlet elbow a spot very near the BOV, pressure drop appears to be around 1.5psi @ 6000rpm WOT.
I don't think that's very good, honestly.
