I'm going to have my car apart in a week or two to remove AC and put on new exhaust goodies (manifold, turbo housing, downpipe, catback...)

I'm working on cooling issues. First step is to ceramic coat everything with exhaust in it under the hood, and then use header tape on top of that. That should help a bit.

Next step is remove AC and condenser. I don't need that thing sandwiched between my oil cooler and radiator.

But how do I get even more air up in there? I could put some shroud around the oil cooler (oil temp 300F), or start cutting bits away from the front grill (the black parts) if that won't weaken the lip area...

Intercooler is sorta blocking most/all of the air in there too, that doesn't help things.

Also, a splitter would be cool, or at least a big ugly cheap lip. Anyone have one of those to try to assist cooling (or downforce)?

I may not need much more cooling after taking out the A/C condenser, but every little bit helps.

TIA,
Chris

 

Cover the perimeter of the intercooler/radiator combo so the air can't flow around or over them.

Good idea, I think air can get underneath the whole sandwich of coolers (Intercooler, Oil Cooler, A/C, Radiator).

Actually my WATER temps are just fine, it's my oil temp that is concerning. If I block that off, I'll get a little better flow to the radiator, but the oil cooler (smaller) may receive just as little.

I'll make sure the bottom side of the coolers are all covered with a plate of some sort...

 

Do you have an oil-pressure guage hooked up? I wonder if your cooler lines aren't on the small-side of things.

You may need a larger cooler.

I don't think a splitter or front air dam would help much with cooling, but would help with less front lift.

The front splitter would be creating a bit higher pressure on the front of the grill (more air, same space). At least that's my theory.

The oil lines are pretty fat, and both the send and return are super hot to the touch. Unscientific, but I think I need more air to it.

I have an oil pressure gauge, oil pressure is good, but I run 15w50 Mobil1 and the actual flow to the cooler is probably diminished compared to a 0w40 or something like that.

 

Is there any damage to the fins/ribs of your oil cooler? That has a dramatic negative effect on performance. If so, you can straighten them with a regular screwdriver of the correct size (if you apply lots of time and patience).

However I'd recommend replacing the cooler with something bigger. If you do that, look into replacing the lines also (with larger). That would necessitate changing out the block fittings too tho, so just a bigger cooler is easiest.

The lip may help. I agree you will increase the air pressure, but I think it's actually the increased flow going into the 'mouth' instead of under the car that will be the factor. Don't you have the stock ITR lip?? (I'd go with that).

Drilling and shrouding will help some. But since it's all blocked up by the IC, the best thing is to go bigger [OC] so you get more more surface area to cool from.

 

don't cut it!

let me trade you! I WANT the front bumper cover with the black pieces..

#55 has the black part cut out.. you won't want my lip though.. hehe..

so....chris....what mani did you decide on???

I also agree with covering the perimeter of the intercooler/radiator combo. If your good with fiber glass or carbon fiber you can make some ducting as well.

Does it look anything like this?


If you're serious, we can probably trade without swapping lips even. But I'd like to know why NOT to do it (bumper sagging, etc.

 

When I first installed my oil cooler, I sandwiched it between my intercooler and the rad. My street temps went from the 260's to the 180's. But then I tracked the setup and my temps hit the 270's (yikes).

So I re-installed the oil cooler above my intercooler so it would get it's own air. I had to cut a hole in the bumber on the passengers side of the emblem and I installed some aluminium plates from the bumber to my oil cooler to force all the air through it. Highest temps I've hit since on a track were in the low 230's.

Are those MF10's or C10's?

 

i believe they're rotas, you can spy the cap

ROTA BABY! Classic white.

OT: Nicey nice! Where'd you get those? 16"?

Thinking about picking up a set. Is it the regular 'bronze' that is like an MF10, or gold? (I know lots of people said the 'sports bronze' [two-tone] was kinda ugly).

Back on topic - I like the idea of moving the oil cooler to it's own airflow!! I didn't think there was enough room in there to do that. On a track car, that might be the ticket!

Ah! move cooler down. yeah I thought of that too, in the shower or something, and probably forgot! I have to take my bumper off and rework a bunch of stuff.

Classic White Circuit 10.. 16" +45.

ive seen oil coolers laid flat underneath thats an option and also i have never seen one offered but a finned or aluminum oil pan would go along way to help keep things cooler.

 

ive also seen oil coolers moved into the wheel wheels, although im not sure what size cooler yoru running.
i would suggest somehow mounting it in front of your intercooler.
how big is your oil cooler anyhow?

10 row. Not huge. Looks about like this except longer oil lines.

 

old school rx7 oil cooler. shouldnt be more than 30 at a yard.

 

what about running a higher capacity aluminum oil pan. The pan itself becomes a good heat exchanger, and the increased capacity helps keep the temp cooler as well.

So aftermarket cooler then, not stock R?


Yes, perhaps wheelwell. What kind of intake do you have? Otherwise on the L side, since you can do without the washer bottle (or fender liners?). Maybe a J's/similar homefab bumper duct to route air in there.


I disagree with moving the cooler in front of the IC. This will almost surely defeat the IC, maybe raising your charge temp to the point of detonation, but certainly to the point of reducing your charge volume significantly (that's like driving your car on a 270 deg day! ). [Theoretically ] it should not have much of a positive effect on oil cooler performance either.

Well, running both coolers. Stock heat exchanger plus the Greddy/GREX 10 row oil/air cooler.

mine looks worse.. and it's a spoon replica lip that makes a nicey nice airdam, but it's all cracked and chipped.. you definitely wouldn't want it..

I'm serious enough to take pictures of mine when I am at the car next to show you, if you're serious.. mine still retains the exact same shape as it would with the black piece in, and it's been out almost 2 years.. the bumper cover is slightly more bendable when off the car, but that doesn't matter much..

 

Sure, we can exchange major bumper blemish pictures, let me know and I'll show ya mine (not TOO much)
