Does anyone know what size radiator the Hellcat or above use? The OEM one in the car. Thanks for any help.
 
Ok, I found Mishimoto's all aluminum radiator size for the Hellcat. The core is a 2 row 24x19x1.96. It is more than capable of cooling an 800+ hp engine with a ton of other coolers up front also. It has an electric fan and can keep the a/c cold. My reason for trying to find this info is I've got a stroker 496 and want to make sure a standard 2 row all aluminum radiator would cool it. I keep seeing people getting 3 inch core aluminum radiators and complaining that they can't keep their engine cool. From what I'm seeing, it's not the radiators, its gotta be some other issue. So my mind is at ease now.
 
A 2 row core of 1.250 tubes will cool damn near anything. Just get s fan capable of 3500-4000 cfm at minimum.
 
I recall reading that 70% of the cooling is performed in the first row. Therefore a 2 row cools better as the first row is wider.
I replaced my 3 row with a 2 row, added a factory shroud, and a recovery bottle and that was a great improvement.

I'm going to use Ford Contour or Taurus electric fans n shroud depending on which will fit between radiator and serpentine bent system. Both are said to pull large amounts of air. It's going to be very close.
 
Yeah, those fans move a **** ton of air!
 
Anyone have any part numbers for the Contour and Taurus fans that people are using? Or what year cars they're off of?

Air flow is measured in Cubic Feet per Minute at a given static pressure, corrected for temperature or density in terms of pounds per hour, not "Yeah, those fans move a **** ton of air!" as quoted by OP #6 above. How can capacity be compared without a meaningful number? Its like saying: "how high is up" or some other dimension-less quantity. Just my opinion of course.

Ok, just for you.

The Taurus/Contour/Lincoln fans are said to move around 5000CFM on full boogie, they are a 2 speed fan that draws up to 80AMPS. There is a Volvo fan that is also a 2 speed and uses the same amps.

I’ve used the Volvo fan, with a PWM fan controller (pulse width modulation). The PWM fan controller ramps up the speed as needed so there isn’t a sudden AMP spike.

In layman’s terms, the **** works great and keeps the engine cool and alternator happy.

Thank you for your information. A PWM controller is superior to the 2 speed design. I used to design PWM controllers, for variable speed drives used on utility boilers for forded draft and infuded draft fans in the 3000 hp range using a high voltage supply (4160 volt 3 phase) and IGBT switching transistors. They work very well when applied correctly.......and nothing beats a "happy alternator" .... except a happy wife or lady....
