I havea trubo stock GSR pushing 300 to the wheels, 11 psi, etc. Im looking to hit the track, but worried my car cant handle the relatively long period of boosting and generally driving hard. i have a dual row aluminum radiator, new thermostat. At normal driving my water temp is about 180 farenheit ( i have a aftermarket water temp guage). I mashed one time on this windy road, about 4 miles, boosting and just driving hard in general, and the water temp got up to 220 farenheit. and man that seemed pretty hot i got worried that im getting close to overheating...

so my question is, how hot is it ok to let me water temp get? Particularly for if i go to a track. just want to know when i should start slowing down and getting worried.

thanks!

 

too hot...

try a lower temp fan switch and a lower temp thermostat.

try an aftermarket higher cfm fan as well

 

180-195 perfect. 220 let it cool down asap. 250 is BOOM.

 

i have my fan wired externally, so its always on. its a half-size radiator, wish i could fit a full sized one

 

220 is absolutely nothing to worry about. going past 240 is when you have to back off. actually, if your water and oil temps keep climbing the car needs cooling addressed period. also by dual core do you mean a full size dual core? we had a pretty length discussion on this in the road racing forum and the general consensus is you don't go road race on a half rad.

 

its a half size dual core... is there anyway to maybe mount two dual core radiators? that would be interesting.. ill check it out in the road race forum thanks. what do other turbo road racers do about the radiator size?

 

you get a full size dual core not two half size dual core....

 

i know a full dual core would be best, but i dont think i could fit it in with my manifold setup. heres a video of the driving i was doing when my water temp hit 220 towards the end. i guess considering it was relatively long drive that wasnt too bad- i think a triple core radiator should help me out nicely.

please dont give me any flak in regards to the video, just trying to make it more clear

and yes i know the tach isnt working

 

get the ebay triple core im using it with no over heating problems.

 

how long/whats the longest youve pushed your car without taking a break, and not overheating?

 

your windshields cracked bro

 

oh thanks... didnt notice...

 

LOL

 

you need airflow to the radiator. if you drive with the bumper off you'll notice lower temps.

 

spal puller fan w/ shroud and your problems are solved... not an opinion... its proven

 

You need a nice fan and your problems will be solved. Get a spal fan with a shroud and don't look back. You don't want your temps past 200imo I had issues with heating and spent a lot of money coating things and it helped but not as much as I hoped. Btw E85 helps a lot also.

 

I don't get why everyone keeps talking about the fan?

Isn't a fan just there to move air through the rad while the car isn't moving?
He's moving quickly, so shouldn't there be sufficient air flow over the rad?

 

driving fast in the wrong lane headed towards blind corners is a great idea... please get to the track before you kill yourself or somebody else and stop driving on the street like a jackass... just my .02

 

Poke a hole in the thermostat. Ull still retain heat but the car will cool down faster. I do that to all my turbo street cars and I also run the stock fan plus a pusher fan in front. I turn the pusher fan on in the burn out box then off. Then again on the return road after a pass. My temps stay below 200.

 

if its clear i dont mind cuttin into the other lane when you have a clear view of no oposing traffic.

 

the way my radiator is places its not exposed to frontal air almost at all. any air passing through it passes throug the intercooler first.

 

I didt read the other replys but install a fan in front of the radiator facing straight at the radiator so a grip of air will go in n the other stock fan leave it alone So more air coming in that works for us in the AZ HEAT 2 fans!!!

 

Yea, my USDM Integra front is the same way. No airflow is coming in while moving except what goes through the intercooler and condensor first. I've thought about going jdm front just for ventilation and cooling.

Racebum mentioned the general consensus is no half sized radiators on the circuits. I've started to accept that this is probably the faite of my car as well. I'm running a single puller fan on the street and I still have issues in 100F temps after a pull when coming to a stop. I've since added a turbo blanket and I'm thinking about adding a pusher fan before summer. I just doubt it is possible to have a turbo integra with a half size radiator that can get beat on for 20min straight without hitting 220+F

 

at least you had a drift wheel for that crazy backroad run....


low temp thermostat and get a puller fan. world of difference

 

Im interested in the same thing. My setup consists of a mishimoto half size radiator triple core with a FAL puller fan. Was thinking of adding in a spal pusher as well. Turbo blanket will also be apart of this.
