Evans Coolant Temps

-
God if I had that much room my motor would be cool too lol. Small blocks are so much easier to package into these cars.

Might have missed it but is that a 26” rad?
Yes it is. It's a 26" Champion. Before I figured out that it was a fan issue I had a nicer Griffin.
 
I didn't have all that much room only a few inches. I had to move the fan motor onto the other side of the mounting braces and remove the cover on the motor.

I have an 1/8” of an inch between my fan and PS pulley and just a few ticks over 2” from the rad to the water pump. Dixie Chicks level of wide open spaces there lol.
 
New SPAL 16" pusher fan came in did two test per Evans and confirmed the car can't handle just sitting. Took about 25min from dead cold to 230. One day with the hood closed and the next with the hook open didn't seem to have a marked change at all. Waiting to hear what they have to say but will go ahead and start saving for a new radiator. Pretty much confirmed what we have all been saying but still sucks a radiator rated for 700hp can't handle one making 600.
 
The HP ratings some radiator manufacturers use don't mean squat. At least you know now.

Yep thought I was doing it right by buying way more radiator than I would need. Well I guess I did with the first motor.....plans changed and I lost whatever headroom I had and more.

Just remember more cores isn’t always better (it usually isn’t better) and 2 big cores will cool more.

If you can fit a 26 inch core in there I’d use that. Cold Case is a great option.
 
On the hunt for a radiator now. If I have to replace the rad anyway I’m really tempted to try regular old 50/50 and see what it does to be honest.

As I’m going thought I’m looking at direct fit and “universal”. Are the pics I’m seeing on summit right, the universal ones have no mounting brackets or flanges at all? I can weld steel but I don’t have means to weld aluminum. Are guys really fabricating aluminum brackets for these universal rads?
 
So looking at Griffen then offer a 22" core with two rows of 1.25" tubes or a 26" with two rows of 1" tubes. What would better?
 
And the assumption is a 26" will cool noticeably better than a 22" correct? Looks like cool case does sell a 2 row 1.25" tube for a 22" that should be a drop in replacement. If that would work that would be awesome and a lot easier than taking the front end apart so i could cut and fabricate mounts for a 26".

I’m not a fan of cutting up these cars if you don’t have to, but I’d rather let Cold Case decide if a 22 is big enough for what you need. I trust them.

@Ccas

Let’s see if we can get him to drop in here and get his thoughts.

Same, if I can avoid a cut and weld I would like to.
 
I called and talked to Rob at Cold Case for a good bit of time. Sounds like the next step is to dump the Evans and try 50/50 with a t-stat again. Evans even suggested trying a 70/30 water/coolant mix to see if that get temps under control. Once I get the temps in check I can get some miles and on this new motor and efi setup.

Not trying to be a smart *** but this is basically what I suggested back at the beginning of this thread. The Evans is not as efficient a coolant. Now the experts have weighed in.

Anyway I hope the water/coolant helps.

I mean even agreed with you on the not as efficient comment so not really being a smart *** is it?

On another note Evans is refunding me all the coolant I purchased so I can't complain about that at all. Just going to send back what I can and they will refund the purchase price I paid from Summit.

Some get their panties all in a bunch so just making sure!! I did the same as your doing and ditched the Evans. I would try the 50/50 60/40 70/30 or which ever ratio you choose first and see what happens.

Any thoughts on keeping the high volume water pump or going back to stock?

For decades the folks in the racing world have used just distilled water and a bottle of water pump lube. Ran it in a Trans am car for 3 years never had any issues.
Very cheap and the best heat transfer you can get.

True but I also don’t want to have to deal with what I’ll have to go through to get the 340 in my dads old bracket race car up and running. Took the rad cab off and just solid chalky calcium build up. Put the cap back on and went back to working on my dart lol.
