2nd Gen Non-Engine/Transmission Radiator upgrade info, again

[Josparkz]

It looks like those aftermarket radiators we were going to get last year haven't happened yet. Some one on this board had a radiator shop and reccommended a brand equal or superior to the Griffins we were discussing. I have not been able to locate that in the archives yet.

Anybody out there have that name?

Thanks.

I'm also looking for the same.

I'm also trying to buy some extra time I can stay on the go pedal while pulling a big hill. Looking for something of at least O. E. M. quality with additional cooling. If we can get something together let me know.

Joe... please keep me in the loop on this one. . I too am very interested in a very HD one for higher HP and towing heavy in REAL MOUNTAINS lol [just kidding guys all mountains need our respect]

ON EDIT. . Joe search for threads using Evil Otto as the poster if memeory serves me he was the originator

I went thru the archives and found the post. "Be Cool" radiators were mentioned as a high quality product.

I also found this other outfit mentioned that makes an aluminum, high performance radiator.

I am sure there are others out there too. It being the weekend , I haven't been able to contact any of them.



The search goes on... ... ... ...

A couple of thoughts here...

The stock raditor is good to 400+ HP.

It is the same one that the V10 uses.

So there is already a lot of margin for those of us who are under 400 HP.



If you are running more than that would be a good reason to want a better one.

I think torque is probably a better measurement to use for sizing the radiator. Going by torque the V10 doesn't even come close to the Cummins.

Sorry, HP is a measure of power, torque is not.

Power will set the requirement for the amount of heat to be displaced.

BTU/min = HP * 42. 44



To be more specific: HP is torque/unit time.



Another way to think of this is:

You could have a very small motor with some big reduction gears that would provide a lot of torque. It would not move the load very fast but would move it. It would have to displace a lot less heat than a larger motor with say no reduction gearing.



Here is the way I remember this stuff:

HP gets the load up to speed. Torque keeps it going the same speed.



The bigger you have BOTH numbers the more fun you have.

One other thought...

The V10 puts out roughly the same torque as the 12/24V but uses nearly twice the HP to do it. Therefore it is faster but less efficient.

Ya'll quit that theory stuff, and get your heads out of the text book......

... . cuz this is how it works in the real world. When pulling a big hill, with big weight, with the go peddle crushing the carpet, the little gauge that measures the temperature of the water moves to the right side (from the left). That means that the engine is producing more waste energy (heat) than the cooling system can dissipate. My truck is under 400hp, and if I kept my foot in it (with EGT's never going over 1300 thanks to good air flow improvements) it would overheat pulling a big mountain, running 21 or 22k pounds. The horse power doesn't matter as much as how efficient the engine is at using fuel, i. e. - How much fuel makes the tires turn, vs. How much is dissipated through the cooling system. It just that simple. Or, you can say if the little needle moves to the right to fast, ya need more cooling.

Or a bigger truck designed for the task. Or much cheaper - take your foot off the floor.

It could be the ticket

It being Monday, I did a little phone calling to radiator shops.

One shop will build an aluminum tanked and cored radiator in the $600 ballpark. What this fellow was saying was that it would have 2 rows of 1" tubes. He made an interesting comment, that if you go any bigger, due to the amount of liquid flow, that you would start to overheat at idle. I had never heard this before, but it makes sense. He seemed to think that a VISTEON # 9125 radiator was an excellent replacement, same 2 rows of 1" tubes, but with plastic tanks. His experience with custumers using that item in a very hot part of the country was excellent. The man said it was an excellent quality product, and a standard production item. I believe I will take a long and hard look at one of those before I do anything else.
