Winter 07/08 Projects and Plans? - Page 9

Has anyone considered running a v-mount setup with the intercooler on the bottom and the radiator on the top, and then having some ducting that routes all the air that goes through the radiator out a hood vent? Or maybe having some type of ducting on a regular setup that routes the air from the radiator out a hood duct? Such as the air comes through the radiator and has to go up past the exhaust manifold and out the hood vent. Seems like this could help expel heat from the engine bay quicker if not help to expel more heat. Only thing I could think of doing would be making a piece on either side of the radiator that goes from the bottom of the radiator up to the hood. Not sure how well it would work but seems like it could work very well. If I get a chance today I’ll make a quick drawing of what I mean.

TJ - I have considerd doing that yes. A design I bleieve Greg Collier had a pretty good turn out with. Takes some work to get it just right. Tilting the intercooler back at that kind of angle you have to make some room in there for all that to fit in those close quarters like that. See if I can dig up an old picture of his setup to show you what I mean.

Ok, here are some pics of his setup. Sorry, but its all I can find right now.

p.s. - I got these pictures from an older thread started by Greg. Hope you didnt mind. Thanks Greg.

I know for SCCA Pro Solo you are able to use ONLY water injection. I will have to double check on that however.

Eagle 5 · 02-13-2008, 10:34 AM

I think I have seen more recent pictures of his vmount setup but yes my idea would be similar to that. Though I think most people have the intercooler on top and radiator on bottom. My idea was switch them and have the radiator on top and IC on the bottom. Not sure if that would affect how the coolant runs or not being higher up but then you could have ducting from the radiator to the hood vent, and with it being on top, would not be as hard to do.

Though the other idea was a normal setup and just having some ducting routing all the air that goes through the intercooler and radiator up and out the hood vent.

Sorry, I was being more pro road race series specific and not Solo stuff. My bad Andy

Yeah, I have not seen anyone try with the intersooler on bottom yet. I believe the general consensus with that is it will block too much of the airflow to the radiator even if you did have ducting feeding up to it. But hey, anything is possible right? Give it a go and see what results you get. All these ideas started somewhere from someone.

I attached a quick drawing of what I mean. Take a normal setup and add ducting on either side of the radiator and have the air somehow directed up and out the hood vent. Hopefully the picture describes what I mean. May help remove the heat coming off the exhasut manifold. Basically a flat piece of either side and maybe something on the bottom to help direct the air up and out. Just an idea though.

More pics of Greg's v-mount:

talonTSIDriver · 02-13-2008, 11:31 AM

I think with the all the A/C stuff removed, proper ducting, hood vent, and a stock radiator, one should have no problem with coolant temps. I run 20% coolant, rest water with water-wetter additive.

No, I see what you are saying and I dont see why it would not work. you going to attempt this and let us know or was just this a brain storming idea? I would be curious to see the results if you or someone else tried it.

I agree with you however, it would depend a lot on the conditions you are running it in as well I would think. Maybe not though. I know Greg had some overheating issues when he first attempted the "V" mount setup in the begining. Now there have been a lot of trial and errors done since then and I am sure someone has come up maybe with a better design. I was actually picking his (Greg's) brain about this earlier in the week.

Again, I think it will all depend on the proper ducting & venting as you said Andy and the load you are putting the car under. If you are running full out for 2 hours or so with a setup similar to these, I'm sure the car would react differently say to if you were just running sprint races that were only 15 - 20 - 30 minutes long you know?

Thanks for the extra picture of Greg's car Chris.

This one track that i attending a lapping day is usually where i see higher coolant temps. The course is not as high speed (top speed is about 70mph) and lots of tight turns. I'll have to test my setup with the new car this year there and post some results. I'll even post a log (DSMlink) to show coolant temp changes, as well as intake temps. I'll post some pics in a few days after i get all my air ducting complete. Key thing, use any openings on the front bumper and direct the airflow to make it useful.

I was just brainstorming though I may still try it once I get some time and its a little warmer outside.

Also, the one v-mount setup I saw in person looked more like this > than like Greg's \| . I wonder if one setup works better than the other.

What are your temps running at now Andy? From your last track day back a year ago when it wasnt snowing up there

Just joking man. Seriously though, what were they?

When I race, mine are around 204 - 207 with 2 bottles of wetter and water. This will change once all the AC crap comes out and more ducting and venting I know. Just curious to see what yours are now.

The way Greg had his \| is about all the room he had to work with and this is on a fully race prepared car. If you are going to try to do a true "V" mount > style, I think you would most likely not have the room in there. I could be wrong, but unless you do some major and I am pretty sure about VERY major gutting and moving things around in the front, this style > would be very hard to accomplish.

But hey, try it out and see what you can do man. But a radiator tends to be about twice the size (maybe bigger) of an intercooler. So try the math first with some measuring of the components and engine bay before you actually attmept to do it you know?

p.s. - You have any pics of the setup you saw where the radiator and intercooler where setup like that? I would like to see how much they had to take out around that area. There is not a lot of room there to begin with. I believe that is where Greg ran into some issues as well.

mavisky · 02-13-2008, 12:09 PM

That setup is much easier on a typical longitudinal type engine, on ours that area between the radiator and the engine is very tight especially if you're running a larger than stock frame turbo. It might even be possible to pull air from underneath the vehicle up underneath the radiator up and out through the vent.

Here's some great homemade ducting I found online on a 2g.

mavisky · 02-13-2008, 12:13 PM

All the v-mounts I've seen place the radiator base clear up where the front bumper is thus making it much easier to damage should to tap someone in the rear. There's room to do it if you do short route piping and are willing to set it up right, but you risk a minor incident turning into a major part failure.

That is a little closer to what I saw. Now the car also had some other custom things done. For one, the exhaust manifold was built in a way that the turbo outlet basically went right into the intercooler. Just a small elbow. Then the intercooler outlet was on the drivers side and the intake manifold was flipped around. The engine mount on the drivers side was also modified to allow the upper Ic pipe to go through. Also had a custom hood vent built into it. Car was more than likely for drag racing but I never saw it completed. I'll see if I can get some pics of it.

This was on a DSM?
