with regular freeway driving, no stop and go, and 60~70 degree weather, my car temps are smack dab in the middle of the 8, but i have the 3rd rad. without it i was running between the 80 and 0 and at the end of the 0.

if you get the 3rd rad you'll have to rig some ducting for it to really work. the stock ducting it may come with won't work with your RSR front bumper.

hey bruce, do me a favour and take some close up pics of your radiator and ducting.

 

I will do that later on today! I was looking at them the other day and I don't have any real ducting to the radiators like the stock cars have.
Thanks Carlos!

 

hey Carlos.. here are some pix!















and my car is still running warm. going past the 0 just about to the 200 line

 

Its no surprise you're running hot. There is no pressurization of the area in front of the radiator to force air through the radiator. I'd seriously consider creating some ducting to force air to travel through, rather than around/under, the radiators.

 

thx bruce. i agree with viper501. the air is actually being deflected by the rads out to the side. IIRC the proper RSR rads are configured parallel with the car's centerline and has ducting that routes it 90 degrees to the rads so it exhausts out to the side. you don't have to do this.. just get some ducting from the TT or gt2 or make some yourself.

 

the RSR rad should be flush against the screen. this pic shows the airflow quite well. ari comes in from the front then gets deflected out the side

 

ok now I see what you mean!! do you have a pic of the TT ducting or something similar??

 

you can use this duct from the gt2. i got the same part but had to trim the hell out of it. you should be fine with your big azz front bumper . the problem is that you are no longer using the side radiator exhausts.

if you are gonna do it right, you should reconfigure the rads and use the proper RSR ducting.

got my gt2 ducts from susnset porsche. had to special ordered from germany. took 6 weeks. you might be able to rig something up in shorter time. have you ever worked with fiberglass

EDIT: after looking at your pics some more, i think you should just fab something up yourself. i can't guarantee that the gt2 ducts will line up.

 

i see what you are saying. those attach to the radiator and the intakes on them typically would sit on the bumper and force the air onto the radiator. HMMM... one thing is to get those, and then modify that to attach to bumper.. basically make them a llittle longer or whatever is needed

i wonder where I could get the correct RSR stuff. I have tried to talk to people at The Racers Group but they always suck for customer service...

thanks for the input!!

 

You could probably fab some ducting up with black plastic sheeting (like ABS), rivets, and a heat gun. Won't be beautiful, but it would work. Could also do aluminum sheet for the same effect. Again, not necessarily pretty but would be effective.

 

e36m3's without additional cooler and ran hard on track will overheat.

i had a 996c2 with about 8000 very hard tradck miles on it. i am not that slow as carlos can attest to that. but my has NEVER overheated. i often run it non stop for 60+ min. at 100+ deg of ambient temp. once was 117 deg at button willow.

if your C2 motor is stock and you are overheating it, something is wrong with your cooling system.

 

ya we got that figured out we are working on something to fix it???

 

Bruce the best thing to try would be to remove the AC condensors from the front either side. Easy to do and our SC'd car got temps way down as a result.. that's the easiest/cheapest way to drop em...

 

and run without a/c?
