Car is completely stock as far as intercooler placement and everything else goes. I was hoping to avoid replacing the stock dryer due to having to fab up even more lines. Would it be a bad idea to run both dryers in the system? I'm essentially trying to figure out how to mount the RX-8 condenser in the stock location and get the lines to connect, Wonder how much a shop would charge to fabricate those.

 

I don't think there would be any harm in using two dryers, but I could be wrong. I'd try to just swap to a good, stock condenser if I were you. I have three good ones, one of one type and two of another, but I don't know yet which are MANA and which are Denso. At least with that you wouldn't have to worry about making new lines and figuring out how to mount it.

I would stay away from running 2 driers. That adds a substantial volume to the system that needs to be filled with refrigerant. Also, just seems unnecessary.

I don't know in particular if it would cause a detrimental effect but it just seems like something to avoid.

Agreed. That's a great way to put it. That's what I wanted to say the other night, but sometimes my werds dont do gud. lol

 

I’m looking to do this condensor mod with a cx racing vmount radiator. What’s the general consensus of running lines. I read the rx8 lines may work and even Miata lines on FB groups. Also what issues will I have if I mount the condensor with the drier on the passenger side with the ends up. Kinda new to this and really want AC before June.

 

You're in a LHD FD? If so, is there a specific reason you want to mount it the opposite way? Because this condenser works out kinda perfectly for LHD models, being that the inlet is on the compressor side of the engine and the outlet is on the passenger/evaporator side. Even if you're in a RHD model it still wouldn't be that bad.

I couldn't get the RX-8 line from the compressor to work for me, but others might. Even if you got the end that connects with the condenser to route correctly, you'd still need to change the end to the compressor because they're different. If you're talking about the high side line (smaller diameter), then I'm not sure. If you use the entire high side line from the RX-8 I believe you need to do some rewiring because the pressure switch is trinary instead of binary like the original one, and I guess you'd have to make sure the ECU has the capability to use the trinary switch also. Unless you can find a pressure switch with the same thread pitch and just rewire a connector for it.

Regarding mounting the condenser upside down, I don't know if it would just be inefficient or not work at all. Dale probably knows more about that.

 

thanks I’m extremely new to this and just ordered the denso rx8 condensor and have the radiator. I’m just looking for the easiest way to accomplish my goal. I’m guessing I’ll just do custom lines. Regarding the orientation I saw a picture of a guy who mounted the dryer on the passenger side but when I read this thread it was stressing the dryer on driver side and outlets facing up.

 

It will definitely NOT work upside-down. There's a pickup tube in the drier so the compressor pulls liquid and not gas, if it's upside down you'll have major weirdness and problems.

Stephen's build thread has some good pictures and info on how he did the conversion -

Basically get the 2 RX-8 lines that attach to the condenser and the 2 closest lines for the FD and have them cut and welded together.

Dale

 

Dale. Thanks for showing me that thread. Those are some great pictures. I appreciate it.

 

I just welded fittings on my rx8 condenser and made all my lines with Eaton hose. Works well so far and pulled 30in of vacuum.

 

Any pictures or a how-to on this? I've not heard of Eaton hose.

Dale

 

Dale, Google Eaton EZ Clip. I used the upgraded version of their house also. Their selection of fittings is unmatched by anybody in the industry. I'm glad I used them.

 

Did any of guys have to move your power steering cooler/lines. I have mine in the shop for the vmount And my mech is saying it has to be moved. Using the cxracing rad/denso rx8 condensor.

 

You will probably need to relocate them, most IC kits require it to be moved or altered.

I got one of these -


Had it for a LONG time, works great.

Dale

 

any pics of location?

 

I talk about it in my mini-build I did a while back -

There's not a lot fancy, you can put it most anywhere since it isn't that big.

Dale

 

Yep, I bought a similar cooler but mine didn't have the sides to protect the fins so I had some welded on. I might have to swap to that one at some point lol. I mounted mine at the leading edge of the subframe. I doubt it gets a whole lot of air, but it doesn't really matter since the PS system doesn't get used much on our cars.

 

Back again. What kind of temps should I expect out the vents. Currently I’m getting 60 degrees.

 

What refrigerant are you using?

A proper AC setup should be 30-40 deg. air out of the vents. 60 isn't cutting it.

Dale

 

im using r134. Here’s a pic of the mounting. I’m thinking I should space out the condensor a little

 

I don't believe spacing it out would do anything in particular.

Hard to tell in that picture, is the condenser mounted upside-down? There is a specific "up" to it. If it's upside-down it won't work right.

Dale

 

If the edge that's facing us is the top end, then it's mounted correctly. If not, it's upside down.

I'm using R152a and I was getting 25-40F temps out of the vents last year, but this year I've had nothing but problems. I'm now getting about 60-70 degree temps and my friend who does auto HVAC says he thinks my brand new compressor is shot, and I checked and it's spinning very freely. Might want to check into that too.

 

yes that’s the top end it’s mounted right. I mean it feels good out the vents for me. The compressor hasn’t been used for quite a few years maybe 10 as it was in a barn before I bought it put a new engine in it. Problem I’m havin though is that it’s popping the fuse if I don’t turn off the ac before shutting off the car and start it up.
