when the A/C is on the car starts to over heat, If I turn the A/C of it still keeps rising as I've reached a tipping point I guess. without the A/C on the car run's fine no matter how hard I push it.
my setup is more then likely to blame as I have intercooler then fan then A/C radiator then coolant radiator all in a row, not many options when it comes to civic EG's, so wondering if anyone has any idea's on keeping water temps down on turbo'ed b16a's with A/C

Bleed system? thermostat opening? I don' t see the a/c lines so this car doesn't look like it has ac

petroi77

done bleed system, thermostat opening Mishimoto 68C, the A/C lines are there

tony_2018

So more detail, the ac condensor is tucked. I don't see how the a/c has anything to do with your engine overheating. Either its heat soaked and while idle your cooling system was soaking up all that heat. I hope you have the fan circulating properly.

Post close up pics of the condenser, radiator, and their fans. Do the fans work? Does the condenser touch the radiator.

petroi77

both Fan's are tied in together so they work at two speeds, slow for A/C and fast for temp, so basically they are always on full speed as water temp trumps the A/C using a BMW fan relay module

Former User

Are the fans blowing air in the correct direction?

petroi77

both fans are working the way they should be. close ups are a bit hard right now as the car isn't with me at the moment. yes the A/C radiator is very close to the coolant radiator

this is what it looks like "bumper=intercooler=A/C fan=A/C radiator=coolant radiator=coolant fan"

Former User

If the radiator touches the condenser or the hot high side condenser line, that could be the problem.

petroi77

the hole idea of putting both radiators one in front of the other is the problem. but what can I do? I don't wanna lose my A/C, it get's up to low 40 C's here in the summer, and putting the A/C radiator back infront of the turbo will just blow my A/C again

Former User

That's a design that obviously can work if there's adequate space and air flow, but they cannot touch each other so that no heat is transferred between them.

petroi77

there is no touching but they are very close, I was thinking about changing the A/C fan type and putting it inbetween the radiators, bar that all I can do is find a smaller A/C radiator and put it somewhere else, or maybe even use the 2nd unused motor for the rear windshield water sprayer and set up a waterjet system

Former User

On my Toyota V6, the condenser and radiator are separated by 1 1/8" air space.

And shouldn't all fans be on the engine side? I don't think having the condenser fan in front of both the condenser and radiator is a good design. Maybe remove the forward condenser fan and replace with a double strong dual rearward condenser/radiator fan.

Welcome to the world of necessary sacrifices for power. Suck it up and roll the windows down, or get an AC compatible setup. This is a known and accepted fact of our world.

tony_2018

ac compatible MANIFOLD. You really need to make sure its moving air in one direction.

petroi77

I understand all that and wasn't complaining but would be nice if there was a way to keep both "have my cake an eat it" that's why I asked for any idea's or maybe anyone had the same problem and fixed it

petroi77

having an A/C compatible manifold just means that its made in a way that you can fit the wastegate and turbo without having to lose the A/C radiator and A/C compressor, that wont stop all that heat from building up down there, I've done what i can with heat shielding down there.

the air is all moving in one direction, i'm sure, I've tested this many times.
if the air flow wasn't doing what it should i would be having overheating problems without A/C as both fan's work at the sametime one pushing and one pulling would make a vacuum in the middle

Former User

Why don't you think your condenser fan may be impeding proper air flow by being located in front of both the condenser and radiator, and also by running at a lower speed than the radiator fan that is located in the correct position?

tony_2018

Well, somethings causing your engine to overheat, you straight said it has something to do with your a/c. The only mechanical thing attached to the engine is the compressor and I don't see how that could be the issue. The only thing custom is the way you routed the ac lines and the way you designed your condensor cooling solution.

tony_2018

You thermostat may be flushing the coolant at a lower temp, but is your fan switch made to kick on at low temps as well? The fan switch and the thermostat work hand in hand.

petroi77

yep its also the mishmoto fan switch and comes on at lower temps 80C

that's one off the things i'm gonna look in to soon. right now i'm using the mishmoto with shroud I think they run at around 2100 rpm so if I go one running at the same rpm or higher for the A/C fan that will help

Not sure where you are located but I had my manifold and DP coated by Swaintech -> White Lightning Exhaust Coatings | Swain Tech Coatings | Industrial Coatings | High Performance Racing Coatings. Using an IR gun I measured surface temps at the collector during a pull between 250-300C

Also do you have any ducting? I used sheet aluminum to help keep air from going anywhere but through the radiator.

petroi77

i have used some sheet aluminum at the top there to make a kinda radiator cooling plate, putting one at the side there would be way to fiddle to work

Hello
i need to know if you have any luck with your heating problem?
By the way I have modified the AC and radiator in raw to keep my AC I am working on turbo project but I haven't installed turbo engine
Thanks

petroi77

yep i fixed my problem by replacing the a/c radiator with a better one, it turned out that the radiator was the problem from the start, just a generic china made universal one that i should never have used it the first place
