I’ll answer this bullshit post and then I’m out. I’m tired of arguing with arrogant idiots. Yes, you are one of them.
I can tell you how I KNOW you don’t need a shroud.
I was just working on a car yesterday. Didn’t have a shroud. Why not? Because I put it together and the fan is close enough it does MATTER.
How do I know it? Because it never over heats. Ever. It was 90 plus yesterday and sitting in traffic and running down the freeway the temp gauge didn’t even wiggle.
I could pull all the spacers off, fit a shroud and all that and it wouldn’t make a pinch of **** of difference. Nada. Zilch. Zip.
I know that busts your balls because your books say it ain’t proper but I don’t care about your books or your schooling. All that did was make you scared to think for yourself.
In the automotive world you are so limited on space that you can’t, under normal conditions over speed the pump or get the radiator too big or any other nonsense.
There just isn’t room. So you can disabuse yourself that you could even do it. You can’t.
So when I say to:
Buy the BIGGEST radiator that will fit. with TWO CORES. More cores isn’t better. And get it in aluminum. It’s lighter and will cool as good or better as anything else. That’s 26 inches in a Chrysler. Can you hack the core support up and use a big cross flow radiator or some nonsense but I don’t cut up cars like. No benefit.
Get a HIGH FLOW water pump. Arguing this is absurd but I’m sure you’ll try. The pumps cost the same so why not?
Oh right, because you put the fear of God I to people with the threat of cavitation. I’ve never seen it at the pump speeds we can get.
A HIGH FLOW thermostat. The best are Stewart Components. Every one of those I’ve used will maintain their rated temperature. Some of the others don’t. If I have a 180 that’s where it should run. Unless of course you want to make the cooling system as borderline as you can. I won’t do it.
For most guys on here you can drive the pump as fast as you can get the pulleys to do it.
I forget how fast the pump is over driven on the car I fixed yesterday but it’s more than 6% but it’s 10 over or a skosh more.
Get a mechanic fan. Period. No clutch fans, no trick ****. The power you save with electric fans is ate up by the power you lose when you can’t keep the engine cool.
See how simple and cheap that is? You buy one radiator. One pump. One thermostat and one fan.
No guessing. And it will cool whatever you have.
Of course being the professional argue-er you are, you’ll cry and whine that I didn’t do any math and didn’t check with a qualified engineer and professional bullshitter like you.
Too bad. Doing it my way saves money and time.
Now go away. I don’t answer to you. I’ve wasted my last second trying to convince you you don’t have a ******* clue what about cooling an engine. An engine in a car, not a book I mean.
