a/c with fmic

[kxfreak125]

Im looking to purchase the vrsf intercooler for my 1g. My car still has a/c that works great and im moving to florida soon. I would like to do the vrsf fmic upgrade to my car but would like to keep the a/c.

Is this possible?

Just make sure you keep the stock fans and factory ducting. That has been the biggest issue for me so far. With slim fans I would always overheat. Now with the stock fans back in and the cx racing radiator I see max temps at idle of 206*. That's with the a/c compressor on full but the system needs a recharge. I would still like to get it lower. I'm making some ducting out of aluminum that seals the FMIC to the a/c condenser. Also putting some copper pipe insulation between the radiator and the a/c condenser improves the effectiveness of the fans. Sorry I have no experience yet of temps after doing a hard run or using my a/c on full blast. I also have never ran with the stock radiator in my car.

ok thanks for the info, my old car had a huge fmic and it used to run hot so i know what your talking about.

What about running a 10 degree cooler thermostat with water wetter in the coolant.

Another option which im thinking about running in my 2g with the vrsf front mount is getting the dual slim fan with shroud setup and an aluminum radiator.

I have the vrsf FMIC kit and was able to keep my a/c. I had to bend the a/c line on the drivers side going to the condenser, as well as trim the 90 degree coupler on that same side a bit for everything to fit.

I have had an issue with overheating, ONLY when on the freeway with a/c on full blast on a really hot day (over 90 degrees). Any other time it's fine.

I believe it's overheating because the airflow is being blocked by the front mount at really high speed. it's not getting to the radiator fast enough. I do also have the stock main fan, and aftermarket ebay slim fan in place of the a/c fan. This was the only way I could fit the piping for the front mount.

I am going to try and fab up some sheet metal ducting, as well as a bottle of water wetter, and a 60/40 water/antifreeze. Hopefully this takes care of the issue.

You could squeeze a couple of small fans on the back of the intercooler it works for me and you can move the a/c line on the back side of your hood latch bracket with a little finness to get you a little more room too.

Do you have a pic of this you can share ?

Read over part 1 and 2. It's a 2g but the same concept applies to a 1g.

I run an ARC 3.5" FMIC, sealed the condensor to the radiator, stock radiator fan, 12" SPAL pusher, and a brand new factory radiator and no longer have overheating issues running the A/C on my 2g.

What made the biggest difference was buying a new factory radiator, and ducting/sealing all the heat exchangers together.

Those of you that are having success, are you running turbo heat shields or exhaust wrap ?

I had the cx racing shroud with their slim fans and they sucked. They move nowhere near as much air as the stock fans. You can keep the stock fans with an aluminum radiator and a 16g setup. Also I noticed that with both slim fans running there was a ton of air being pushed out between the a/c condenser and radiator. I foamed the area between the radiator and condenser while switching back to the stock fans so I can't attest for how that would've improved their effectiveness.

I have my exhaust manifold, O2 sensor housing, and downpipe all heat wrapped. I am still getting some serious heat under the hood because the turbo is exposed. I need to make a heat sheild for it.

Does anybody have a link to a turbo blanket for an MHI turbo. I know they're not recommended for bottom mount turbos but it would look a lot better than anything I can make.

I'm running a tubular ramhorn manifold that is heat wrapped, but nothing else is.

If the ducting didn't help, my next step was going to be to heat wrap the downpipe/WG dump and put on a turbo blanket.

I have one on my 2g. I kept the factory engine fan and changed the a/c fan for a slim one. I live in FL and the temps are 93 and up but it works great.
