Clearance issues with 7 blade "hemi" clutch fan and my radiator. Need another fan choice.

Your situation apples to you...only....pipe line engines of what size and hp?.....temperatures and pressures and volumes involved? Size of radiator hauled on wide load semi...means NOTHING without NUMBERS....sizes...dimensions, materials of construction.....Have you ever been around high temperature high pressure heat recover heat exchangers??? For instance, heat recovery heat exchangers with 2000 degrees wast gas (volume and composition of heat to be recovered) to 1500 degrees preheated temperatures at 150 psi pressure, flowing 3000 cfm flow using Inconel 800HT alloy stainless steel pipe and plate, to ASME Section VIII, Division 2, fired/unfired pressure vessels?? It is highly likely that you do not understand thermodynamics or to be able to perform the required calculations. Your argument is about apples and oranges and doesn’t apply to your reasoning. If you want to debate qualifications or design and installation experience, send me a PM. Your initial comment "everone that commented to me agreed" except me is correct......how many or those people you polled, understand the principles of thermodynamics.....I would guess zero. Premises without substantiantion is nothing more than guesses or hearsay.......punt......

My guess is you just don't understand the principles involved.......

Please read my post again

It IS an easy job.

Ah, thanks. I forgot he was replacing the radiator at the same time. Not replacing rad at same time, not fun.

STOP FORGETTING THINGS LIKE I DO !!

My guess you have never had a "bone stock " hi perf. car over heat therefore you ARE IRRELEVANT TO ME !!

Your guess is wrong.... If you had relevance, or any forthoughtt, you would understand the principles of thermodynamics.....and yes you need to describe "bone stock" and your conception of what that means........but maybe you can't do the calculations and rely on the "my buddy knows best" or believe in the DFL factor??.......

YES......IM GLAD I AM AN ENGINEER......for without us, 95% of the FBBO forum members would not have a classic car to show, tinker with and just enjoy having it.....instead, they would be either walking, riding a horse, traveling by covered wagon or living in a cave.....without the ability to text or tic-toc or Facebook, or what ever is the venue du jure. Chastising is the typical adverse comment.....but without the engineers of the world, where would these critics be????......."just my opinion of course".....

I was probably racing a hemi super stocker before you were out of hi school .
My automotive experiences aint , ''AND NEVER'' will have anything to do with what you did , or do !! You sound like your stuck on yourself > big time !

A lot of engineers actually suck when it comes to common sense !

still doesn't compare with twice the h.p. being cooled , on a stock system or ,
dont mean squat to a bone stock a 1969 440 that was barely adequate back in the day in heavy city traffic in the summer time , back in 1969 !
those big cars were actually lower h.p. versions too .

Big cars require more fuel and sustained HP to get them to move and keep them moving which equates to more cooling requirements. Peak HP means nothing if your running at part throttle most of the time aka on the street. If it takes 50 hp to sustain 40 mph, that’s what it takes whether you have a 318 or a 540. Big motor requires slightly more hp (and heat input) to overcome internal friction losses. Most folks aren’t operating at WOT all the time.

Yep, in post #10 there's a link where I use a 2765 jaguar clutch with a 22" radiator. The 2947 is slightly shorter, I haven't found a need for it yet though.

I used a CVF Wraptor serpentine belt drive system in a b-body with AC and needed this short clutch to fit the seven blade fan. I spin it all 7600rpm on the shifts and it’s held up for 6 years and cools great.

thanks , but there are very few people I trust , and you ant one of them ! I m sre glad you know more about my cars than I do too !---f--- o--

That would make anyone run like lightning!!
