Pre-solution Dont read if in hurry....
As some of you might know I have had cooling problems with my SR for qutie some time, At first my water pump blew. So I had to do a quick 411 and get a new one, I called up my people, and scoot and mattback had one at the place formaly known as Secret Services. Great, so after that I figured it would not be wise to use the stock mechanical fans, so I used the Flex-a-Lites that I had laying around my house. Well I first discovered that I had a cooling issue, when I was riding home from estavan's after he fixxed my problem (bad ECU) After that I got a koyo, but not even the 3 times as big as stock radiator koyo could fix my problems!

Solution!
I finally thought of a reason of why my car was overheating when I turned on the AC (it was ok, aslong as I didnt turn on the AC, but this is florida...I need my AC, R12 baby) I soon relized that all the air that was entering the front bumper went though my intercooler, and under the car. Well when this happens no air flow goes though the radiator or AC condensor making the car run hot. Last weekend I made a panel out of thin aluminum using rivits to hold it in place. Holy Jebus! did I make a difference! before the panel if I turned on the AC the car would go past 200 degrees andupwards of 225 degree's within 15 minutes of me turning the AC on, with the panel under the car and the AC on full blast i rarley see temps past 180F. This is the best mod I have done yet, and the best part is it only costs like 10 dollars. Now I can run the car all the time with AC, and never worry about overheating...of course this is when summer is ending so I wont get to much use till next summer. If any of you with koyo's have some cooling issues. I would look to this as a good soild solution!

 

any pic's

 

Good info!

I was talking to Kevin from C&R Racing who makes high performance radiators for race applications and was venturing/testing out some radiator/spal fan combos for the import market, mainly the Nissan 180/240sx with swapped motors. He had stated that because of the fin count on some of the aftermarket radiators matched even with dual electric fans cooling would still be an issue.

He was working on a radiator/fan combo that would beat out the typical Koyo/Fal combo while only running one electric fan. But due to the demand of his test kits and lack of radiators he suggested in the meantime to do exactly what you did. Either purchase a cooling panel for below the car and/or infront of the radiator or make your own.

He said it would dramatically reduce the heat and force more cool air coming through to actually enter and cool the radiator(or something to that effect). Also talked about running Water Wetter and Distilled water, but thats another topic in itself.

 

Awsome man, definately good to know.

 

so... you made a flat panel to somewhat direct air to your radiator and condenser and it works. How low to the ground is it with the HE's you got?

OR

is it above the FMIC?

 

PICS Please...

I am debating if i should do it with a homedepot aluminum sheet or should i just but the oem plastic undercover?

The oem cover is like $50, I believe Jesse just bought one.

PICS would really help, if you can do so at your earliest convenience.

Thanks

I don't have a digi camera here in tally, but its fairly obvious I would seem. Maybe i can draw a pic and post it online. If you open the hood, it goes from right infront of the IC (attached to the bumper with rivets) goes back to the radiator support...where the TC rods connect to with. Basicly take any open space between front of the car to the radiator. Stuff as much air as you can inbetween these points by any means possiable...

 

Ah.

I was under the impression you were going all the way under the motor. Covering the area between the radiator and the motor as well?

This way the air coming in from the flow, wouldn't just escape down below the motor but rather hit the motor head on making it more efficient. In my case i don't have the clutch fan, only FAL's on KOYO and no oem undercover.

rinku and i are currently going to take my factory s14 stock undertray and make a mock up from engine crossmember forward traced onto cardboard and make an aluminum one to do what chin has described. rink is currently running no fan shroud, no upper cooling panel and nothing on the bottom. he has since secured an upper cooling panel and we will make the lower. we will post up our before and afters.

cheers
