Instruments for measuring air flow through radiator


I have an aluminum rad in my 67 350 crate and air conditioning. 

 

 I have a flex fan and a spacer to position the fan.

What I am experiencing is the temp continues to rise when left at idle for a few minutes.  The temp will go to normal once I get moving and get  some air through the rad.

 

I want to consider putting in a 5 blade fixed fan and measure air flow at idle compared to the flex fan.

Quite normal from what I have experienced. Does it go dangerously high? Lots of times if traffic is real slow you can just go in low gaining some revs and at the lights just rev it up abit. Doesn't take much too much to make the difference especially when it sounds like you have a good radiator system.

Fixed that link.  

Looks like what I am looking for.     

Change fan and measure wind speed at the front of the rad. 

Looks well made with good features including wind temp going into rad..

Could even adjust idle speed to see what air flow you get..

Do you have a fan shroud? If not, that will make a big difference at idle in traffic.

A custom aluminum fan shroud was built when the A/C was installed.

I am surprised with your system that you are having problems. It is not like you are producing crazy horsepower or anything. Does it actually boil over? I would be checking out the accuracy of your gauge or else using this new expensive coolant which brings engine heat down about 30%. I will find the name of it. I have a couple friends using it in their hot rods which are producing 800+ horse power. Supposed to be very effective. Good for life with no breakdown and I think may even be waterless.

It is Evans waterless coolant. Has a boiling point of 375 degrees F. and if it freezes at minus 40 it doesn't expand but actually contracts. They don't give it away but it sure is effective. Not that you want your car running at 300 degrees though.

Sure is expensive on first look.   Needs a product to eliminate any water content. 

Very interesting.

Good info to keep

Thanks Jerel

I placed an Amazon order for the Wind meter at a cost of 32.00 and should have it tomorrow using Prime. 

Silver Steak (Dale) offered to send me an instrument or 2 but he is in NB and for the cost of the Wind Meter it did not seam reasonable to ship the items both ways.
