Customer's car, Motor was built somewhere in Florida. Guy bought it from someone in Florida and i went and picked it up for him. Its a lsvtec, with arias pistons, eagle rods. GE Conversion kit, ARP hardware all around. stock b16 head, blah blah blah.

Its in a CRX with a Go-autoworks entry level setup, so the half rad is cocked with a new 1200cfm fan from lightning. Problem is, when it starts to hit boost it starts to creep on temps. 190-215 degrees, way too high for my liking. Not even tuning vtec yet. Only hitting like 8lbs.. and the temps just start to shoot up.

Compression tested the car its 180-185-180-180
Leakdown showed 3% on cyl1/2 and 6% on 3/4

No leaks, no bubbles... I bleed the coolant 3 times over. At first he had a small fan on there with like 800CFM, i told him get a bigger one. He did, and now he says he's still creeping high. I haven't seen the new fan yet, but he said he even tried two fans and it still didn't work. I told him try just the new one.. but i wanted to see how people were setting up their radiators in CRX. There's no ****en room in this chassis at all and everythings so close.. Any ideas would be nice.
He'll be coming by tomorrow, and i'll be looking it over again, i'll make some pulls and post the ectune datalogs for anyone who cares to see it.

 

sounds just like my shat! soon as u hit boost temp gage climbs up faster than my rpm !

 

Is he running a shroud around the fan? If not you will always run hot you need a shroud around the fan to get max cooling!!! something like this should help http://www.buyimportperformance.com/..._p/fal-125.htm

 

He's running something similar. The new fan is a 12'' where as the last one was 8'' i believe. This is a quite faster pulling fan then the other..

Car still overheats.. I'll know more today when he comes by the shop. I just wanted thoughts or opinions. I'll figure it out eventually.

 

I had this same problem at first too.

Does it have an aluminum rad or stock..?

If stock I'd go with aluminum.

I picked up a shroud for mine, deleted the thermostat, and switched to water with water wetter, and all my problems went away. It was only like 70 degrees then though, so IDK how hot it is down there lol

 

get a 175deg thermostat. i have a slim line fan with a minimal shroud. in boost, on a 95+ degree, humid florida sumer day, my temp never saw over 185. Idk what other factors you have going on, but its a good starting place.

 

Dual core aluminum radiator. MUUCH better at dissipating heat than the factory radiator.

 

The main issue is the radiator on an angle, the air isnt flowing through it its flowing around it. you need to find a way to force the air into the radiator, the fan isnt going to keep it cool enough especially a 1200cfm 12" fan. not even a shrouded 12" fan is going to cut it.

step up to a 14" spal or zirgo which will put you arouns 2400cfm and again duct the front end air to the radiator so it cant go around over or under the radiator otherwise it will still run hot. i dont see 190 being an issue for temps but 215 is a little warm but for that setup and the extremely poor cooling setup its really not bad.

i generall run around 196 and 210 boosting around 425hp in my dc chassis with a half core radiator and a large fmic which really cuts down on cooling abaility of the radiator due to poor air flow.

The 170 thermostat will just stay open and in this setup i dont feel would benefit you because your not getting the proper airflow to the radiator, it will probably heat up even quicker one the higher temps are reached it will start getting hotter than you are seeing now

i tuned a ef sedan with a radiator setup like that and he was running a 12" and we couldnt get into vtec without it getting way tot hot, i got him to upgrade to a 14" zirgo and though it kept it cool enough to tune and boost the fan ran non stop and it would hover 198-210, so if fan craps out quickly overheating

 

Its a Flud dual core alum rad.
The fan on it, is suppose to be a 12'' 1200-1500 cfm somewhere in there.

I'll take some pics tomorrow when he comes by, but the intercooler is so friggen big it blocks what little airflow it has. My initial thought was its not getting enough flowing air around it, but there's really no way to get anything more..unless he runs with his hood off..
I'm just looking for other's opinions.. i've usually not had any overheating problems when people ran the correct cooling setup..

 

If the intercooler is to big maybe you can run a duct that forces the air in the direction of the radiator so it has no where else to go.. Its a possibility..

 

Sheet metal to for e the air to the radiator basically make a tunnel to the radiator and make it run cooler. Even with the fmic it will still get some airflow. Also needs a larger fan and possibly ducting as mentioned about from side of intercooler or something
