But WHY do you think you need a "thicker" core......modifications to the engine do not dictate the size of the radiator....unless its an aftermarket aluminum unit being touted "it'll cool an xxxx hp engine" by the vendor.. now here comes the pusher o puller electric fans....up dated alternator systems, all solutions to fix nothing.....except a perceived need.......just my opinion.......
Totally agreed!!!
Some (many, if not all owners) have no real knowledge of how the Mopar cooling system operates or what criteria it was designed and believe on the "seat of the pants" engineering principles and apply aftermarket parts based on some magazine article or buddy or vendor at a trade show and those owners NEVER ask for calculations for the equipment being purchased. Just like the analogy of chrome or aluminum valve covers, enhance appearance but not performance. ........ because, everyone knows aluminum radiators are best.....???.....then bitch about clearance dimensions or lack of performance......but i guess that's human nature ......and ...yes this horse is definitely DEAD.....until it gets resurrected........just my opinion........Totally agreed!!!
The OE vintage mopar cooling systems were overdesigned...
Today the majority of reported issues for cooling is due to faulty engine tuning and/or mismatch of cooling components.
Some will install an aftermarket aluminum radiator that has fewer and/or smaller internal tubes, or wrong pulley.
Then many times one will add some electric fans without realizing How Much Current they draw?? And end up overloading the electrical system..
Just my $0.02...
WHO SAID I THINK YOU NEED A THICKER CORE ?? Bob.... thermodynamics was one of my core curriculum for my degree, so don't try to bamboozle me. I'm conversing with a member. And if you think a modified engine does not need to address the cooling system, then you don't know what you're talking about.
A lot depends on the quantity, in terms of Btu/hr, temperatures of both the in/out of the heat source, temperatures in/out of the heat exchanger, the velocity of the coolant circulated and waste heat generated (assume 80% heat generated performs usefulwork, not waste heat)....what are your design parameters?? I too, studied thermodynamics as a component of my degree as well. I'm not trying to bamboozle you......sure, a modified engine needs a cooling system DESIGNED to handle a specific waste heat...not arbitrarily accepting the "recommendations" of some vendor......a "thicker core" is somewhat arbitrary and meaningless unless surface area (regardless of construction materials, number and size of the tubes in the tube sheet), velocity of the coolant thru the heat exchanger tubes and air temperatures both in/out of the air stream and the CFM of this air volume, with ambient temperature factored in.......and......to what degree of performance is needed or expected ...... possibly assuming a 90% efficiency???? There are several software programs that will help make those determinations....or....Mathcad, permitted the user to write their own formulas to solve the problem.....perhaps, you've heard of Mathcad.....just a thought.......
BUT, those early engines mostly didn't put out the h.p. that we are getting out of our engines , some of us , twice the h.p. ...
Disagree , more h.p. creates more heat !!!
WHY?? Show us yout calculations or suppositions that support your premise....But all the "extra heat" generated does not go to cooling system......if your engine produces 800 hp, does all that power go to the radiator???? Or to make the car go faster??? In what form is the extra heat categorized?....parasitic losses?.....what were your design parameters? Do you know??........
I was mainly making my comments on fairly stock driver’s. My question, hopefully someone more knowledgeable could explain it.
What's the final gear ratio and engine RPM for both examples?? Assume both specific are the same, the cooling requirements SHOULD be the same. Regardless of what wax or oil used or spark plugs used or tire pressure ..... if two factors are same thing, then they are equal to each other......an old plain Geometry true-ism.......just a thought.....
Yup. The more HP an engine makes, the more heat is generated. To say otherwise is silly, and demonstrates a lack of knowledge of thermodynamics. If someone says otherwise, they must've FAILED that course. More heat of an engine is lost, than is used to produce power, which requires a cooling system adequate to dissipate the added heat. Don't take my word people, I'm a dummy, just look it up.
What did your R/T have for a rad? Did you have antifreeze in it?
