Thinking of a different way to duct a radiator, to keep front trunk space... Options

[Dr. Roger]

I was thinking of using two smaller radiators and two fans and ducting not only the intake but the exhaust through the fenders.

This would allow more usable trunk space....

Try it, take lots of pictures of how you are doing it. When it is done, test it out real good, drive in some heavy traffic, stop and go, and drive up some steep hills or up to the mountains and let us know how it works. I thought about all different kinds of ways to do it, when it was all said and done, the only way to go is a Renegade system. Thats just my opinion though.

IMHO, we need more people thinking "outside the box" and trying out new ideas. There's a lot of hear-say that is passed around. Do it Roger.

I'm not clear on where exactly you're thinking of placing the radiators. Care to modify a picture?

Roger,

This is what I plan for my V6 conversion to save the trunk space. I don't know if it will work for a V8...

If you use finned tubing you get about 170 sq in per ft of tubing cooling surface.
That will pulls alot of heat out before and after the radiators.

are you thinking the rear fender wells for the radiators?

[Dr. Roger]

Hmm, I hadn't thought of the rear fender wells but that's an interesting proposition.

I don't have the rear flares to duct from. Did you have some thoughts on that? Draw air from where?

No I was thinking almost exactly what Felix's pic shows. Only from the existing light openings in front bumper.

You guys are great for bouncing ideas by.

Finned tubing?? Who would have thunk it?

Any and all ideas are greatly appreciated.. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

ok, this is a very lame pic but i kinda' shows what i'm thinking...

[JB 914]

if you were going to use two small radiators why not attached them to the rear engine lid w/ a fan underneath?

I think you could use some modified fab like Scott T. did on his suby conversion to draw air upwards then thru the fans onto the radiator and out the lid grills. kindof a scoop?

[Dr. Roger]

wouldn't that draw air from around the headers/engine area??? pre-heated air trying to "cool" the radiator water?

Oh Jeesus! Did Joe Ricard ask for a diagram? (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Probably some.

But, everyone told Scott T. his way wouldn't work and he drove it cross country with no problems. He did some fabrication to draw air from under the car into his radiator which fit in front of his subaru engine. why couldn't you do it in a similar fashion and draw the air up further?

I'm just throwing some alternatives. The Renegade system is proven and works great. But, you loose the trunk and have to cut the wheel wells.

i was thinking out loud.

[Dr. Roger]

very interesting on that Subaru idea.....

so he ducted from underneath the car for the fresh air source?


as you all know, having the radiators up front allow for the ram effect at cruising speed. no fans.

was the subaru setup for "no fans" operation at cruising speed?

all of the front radiator solutions i've seen so far are sooo intrusive.

i think the aluminum ducting would work and it would look cool. i just want to impress the tough crowds at the next IHOP breakfast...... (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

it's Scott Thatcher. look up his posts. i'm sure he has put some pictures of it up here. i don't remember if he had a fan or not (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

What about 2x what Felix has there, that... new thing...

One on each side? Make sure you cage the crap out of the inside of the wheel house... you don't want her paddling a rock through yonder..

yea', i'm wondering how the boxster protects it's radiators...

i'm thinking more towards the inner fenders for the exhaust. just ducted in.

NOT inline of a potentially fatal thrown rock.

[redshift]

Oh I was totally thinking the same kind of thing... but I couldn't think of an elegant way to carry it on out the side, and away from the brakes..

The only thing I could think of would look silly on a teener... a BMW 507 type exit, or God help us... gills.. I mean there isn't enough room, width wise, to pull a 935 trick..

No, no... and NO!
