Question for all of you A/C guru's. I have an 1987 BMW that I put a new Seltek Compressor and P/Flow condenser in this last summer but when it get really hot like 95+ it just doesn't cool as well as i would have like. I live in southern Utah it gets really hot like like 110 in the summer.
THIS is what i ordered from ACkits.
I used the 14x20.5 condenser, but i am wondering if may have not installed it right. I was not able to get right next to the radiator so there is about a 3 inch gap between the condenser and the radiator
Here is a picture of the install. I also put a 14" fan in front. It is not in the picture.
SO i am wondering if i am not getting enough air through the condenser OR do i need more condenser for my high temp environment? which is where my question of can I stack two condensers on top of each other to get more cooling.
I would not have the gap that is shown (move up) and would see what can be done to get it closer to the radiator.
You have enough condensor for the job, but the air is not going through it.
If there is a 3 inch gap between the radiator & condensor, you need to find a way to seal that gap. Normally this is done with some foam tape, but with a gap that wide it might be better to fabricate some rigid material. Open cell foam tape about 1/2 inch thick should be used for where you contact the radiator face to avoid damaging the radiator.
You could build patterns from cardboard & trial fit them for testing, but I would recomend a more weatherproof material for the final part. I suppose you could use some 1x3 inch foam strip, but it may difficult to keep in place long term.

That is what i thought,.I went a little to large on the condenser and did not account for the long bends on the hose connectors. I was hoping to get the condenser close to the radiator but you can see the I have frame in the way.
I have a sheet of 3" stiff black foam at work i think can disappear. I used it to fill the air gaps behind my new downflow Liebert Computer Room A/C units.
I will give it a try and post back the results.
Thanks you for your help.
One other questions that i just thought of, and the only reason i am asking is i have other people on bimmerforums.com that want me to do a write up on this. The BMW e30 body style (84-91) has a large group of enthusiasts and i lot of people would do this same thing if they had some basic instructions.
If i went with the 14x15 P/flow condenser would that have been enough? I would been able to do a better install and get it right up next to the radiator. Would the smaller P/flow dump enough heat? I understand that there is alot of factors involved. Just asking the question.
Again thank you!!
