Overheating Issues, Perplexed

[razerwire]

It would seems to me that the water has to stay in the rad for a time so the exchange from air to water can take place. I show size and tilt of rad. in my post so you know it can be cooled. Tilt will effect the transfer of water to air going down the road. Running the water thru the rad. to fast will not give the rad. a chance to exchange heat.

My problems PALE in comparison to yours. I am sure you'd LOVE to be chasing an overheating problem in your newly completed car. I am feeling for ya.

Well that's exactly what I thought, though I have had two radiator companies (one of which was PRC who supplied my Hurricane radiator) tell me that with aluminum that is absolutely not the case. I failed to ask Fluidyne that, but you can bet I will tomorrow.

In my case, misery does NOT love company. I am thoroughly enjoying the fact that your car is up and running. Enjoy it, you worked very hard on it and it looks great.

Try the restrictor washer, If your pully is over and water pump to efficient, the water is moving to fast through the raditor. That what was wrong with mine. Put the restrictor in, temp came down.

What you say here is true but you need to keep in mind the "normal" RPM range that a typical water pump operates in. This would be from idle (say 900 RPM) up to 6000 RPM. When we speed the water pump at idle, we are moving the flow characteristic of the radiator from a limited flow rate more into the range that would be the case at light throttle/low rpm cruise. I have used "overdrive" water pump pulley's on two motors which were "heat monsters" and they helped in both cases.
