In process of putting drag car back on the track for next season. Will be running electric water pump, and have 26" 4 core radiator now to go in it. Curious what guys are running and recommended for electric fan on the radiator / shroud or not?

What you have may work fine if you can keep the temp consistent....For the drags, not a lot of radiator & fan is required....Its the street that really tests a system....So for drag only, any universal 2 row 1" -1.25" tubes, typically a 31x19 will fit with a little work, and a set of cheap 12" dual electric fans....I ran that style setup for the last 20 years, until I put a Calais Hemi cast iron block in, and that damn thing is tough to cool on a 90* day....Switched to a 1.25" tube & spall 14" fans and a 50gph water pump...did the trick....

For me, I would find a wide tube universal rad that will fit, with a sheet metal shroud and 1-fan, and go with that...I like the Griffin ones best with the 1.25" tubes. Had Becool, and the Griffin way out does it. I had a shroud made for mine by Wizard cooling to gain the over sized fans, but for racing, one is all you need.

I have always had the best luck with SPAL. For track use only with an electric pump you could probably get away with just using a single 16 inch.

Griffin radiator, direct bolt in replacement, but w/ 2 rows of 1.25" tubes. Meziere 42 gpm electric water pump.
Electric fan and shroud combo from a 2003 Dodge Viper.
It does pretty good, but tends to heat up on extended highway driving...65 mph at 3k rpm. Needs more water pump IMO.

I had my aluminum rad custom made to still look somewhat Mopar style with two huge 1800 cfm Derale electric fans and -20 AN weld bungs. Keeps this car with more than double the horsepower of my other cars even cooler than they all run on the street.

Big believer in Derale fans. US made, they move a lot of air, and they last.
Sales guy at Motorstate( Lane Automotive) went to a seminar at Derale few years back. When I went in looking for a good fan to replace the fan that came in my current car when I bought it, he was emphatic not to use anything else they stocked except Derale. They had Spal and many other brands to choose from..
Installed it, night and day difference, couldn’t be happier.

I run a pair of Derale High Output fans for my Hemi and I have no cooling problems even with the AC running in the Florida heat. Quality fan and they flow a lot of air. I had Spal fans before. They were good as well, but the Derale fans cooled my application down better.

I run a Taurus fan on a 26” aluminum radiator that’s under the trunk. It never gets over 180* the oem fans crush any aftermarket one. 90s Taurus fans are good, so are 98-02 camaro firebird fans.

iagree If you have the room for them. If you don't, then aftermarket is the only option. An OEM fan is not an option for a Hemi with serpentine belt accessory drive in an A-body, which was my case.

Mine runs a late model junkyard Dodge Charger dual fan set-up. Easy to fit. They move a ton of air.

This is a good thread...

I'm considering installing one or two electric fans. I run lots of pylon autocross and HPDE/HSAX events... and after a while of long running time on the tracks, the temp rises... so I run with the heater on full-blast to help reduce some engine heat.

I have a recent new US Radiator Triple-Flow aluminum radiator, two 1.25" rows, 22" width (properly fitting my core support opening), factory fan shroud and 7-blade aluminum clutch fan, have tried different thermostats.. 160-180-195, etc... runs great while normal driving... but when racing, especially lengthy sessions, the temp rises and gets pretty hot... changed the cap to a 21#... temp still moves up to around 220+... only under lengthy racing conditions.

I also added a foam filler (2" round) between the upper radiator tank and the core support... so to prevent air from traveling away from the radiator.

So, I'm considering adding an electric fan... behind the radiator as I have a large automatic trans cooler in the front. I'm also planning to add an upper flat shroud from the grille-to-core support... as I see that many road racers have that added.

Since the radiator is only 22", I may add two electric fans and they would then likely over-extend the radiator width a little.. and that's OK with me. I would further have to remove the 7-blade clutch fan.

Comments, suggestions for electric fans on a 22" width radiator? My thoughts are that while idling after the runs (example: HOLLEY Bowling Green MOPARTY with lots of runs!), the electric fans would help much more, but... on hot lengthy HPDE lapping sessions, the temp has still run increasingly high during those typical 20-30-minute track sessions... really hot on warm summer days!

Twin spal pushers and an old Be Cool replacement rad, originally for a 528 motor. I guess it works OK on the 572, generally keeping the temp around 185 degree after a pass, back to the pits and pootling around on the street. I think it's marginal, I'm considering going to a dual or triple pass rad, I just don't have the room for big fans.
That having been said, last time out we had a faulty fan controller, I've just upgraded to another digital controller. It uses a screw in NPT temp sensor rather than a thermocouple that pushes into the rad fins. We'll have to wait a while see if it improves cooling though.

If you have a small block they are a little tougher to fit because the engine is longer than a BB from what I understand. I use an electric pump and the thinnest fan I could find and its a super tight fit. This is a 4000CFM Delta Pag fan and Meziere 35GPM pump with a speedway dual pass radiator.

Custom built B-Cool, 2 12” spal pullers. I just finished the 3/4” shroud. Have to wait till summer to see how it works.

Any concern with the lower rad hose not being near the bottom of the rad?

No problems with it. Any lower the lower hose wouldn’t clear the oil pump. I would have to find some crazy curved hose to clear the oil pump, probably impossible.
