Re: E28 Evaporator core vs. E12
Yes, that was my point, the more airflow the higher the temp will be. The expansion valve "should" keep it from freezing up but I had my first E12 freeze up one time when it was just a tiny bit low on charge. Noticed the lack of airflow and when I stopped to get gas a huge puddle formed u...

Re: E28 Evaporator core vs. E12
Serious question: has anyone ever measured airflow in cfm at the outside vents? Less than a heavy breather. I don't have a cfm reading, but Road Test magazine measured the air out of the 1975 530i's vents as approx 40F. The stock system will make cold air on R12, if you have no leaks and everything...

Re: What Sanden AC compressor do you recommend?
I have been using the SD508 Sanden unit since 2001, and it seems fine.

Re: It's Alive! It's Alive!
Finally got the old 530i fired up. :D It seems like it was a combination of fuel and ignition problems. The fuel pump had failed internally and I had the timing way off when I swapped out the distributor. I installed a new fuel pump and I bought one of those whistle gizmos that you insert into the ...

Re: 76 530i motor&5spd into a 74 Bavaria?
Yes the carbs would bolt up fine, but there may or may not be provisions on the later head for a mechanical fuel pump. Installing an electric fuel pump would be easy enough, but as cranky as those carbs were I'd just convert the car to FI. The major stumbling block I see is the driveshaft, a Bav ha...

I know dot 4; but any perils of inside info. Thanks All it says in the owners handbook and Haynes manual is to go up to t...

Re: Fuel pump psi?
Doh! My eyesite must be going. :D So that would be 43 psi. I believe generic fuel pumps for carburetor engines would be 3.5 or 5 psi so not sure if that is enough pressure to run a fuel injected motor? Unfortunately the low fuel pressure for a carb engine isn't enough for any injected motor. The ca...

Re: 1980 Euro 728i
A Euro 728 would have a higher compression 2.8 engine, probably 9:1 instead of the 8.3:1 of a US spec 530i. About the same power but a touch less torque. The euro car might have a hotter cam and would have a different curve on the distributor, and of course would not have come with all the smog equ...
