Young1 I race 95% of the time. The dual fans look cool when running. As far as help in cooling This works both ways. ERA sell there SC car with a splitter in the opening. I know of guys who run this and guys who run fans. Both have no problems with over heating. This is with a street motor like a stock 428 or 427 late motor. This doesn't apply to a 500+ aluminum monster. I do have a 482 in my car at this time. Cooling is ok with steel tubing in the long run for the bottom line from motor to radiator. wire core hoses to prevent collapsing.
With the fans in the opening they block air flow into the radiator. Have to remember that our raditor is at 20 degrees and not straight up and down. It is easier to bend air than force it to turn down.
In traffic any extra air being blow through the radiator will help. If you are in traffic I recomend cracking the hood to give the hot air some where to go. Putting shroud on the radiator will help pull more air through. Finding a higher CFM fan to pull air through would also help. Make sure the wiring is up to it, your charging system can handle the extra amps. Have seen and had my car kill the battery with car running too long at slow speed and all power ideams on. Some guys are running a Ford Tauras fan setup. Have no info on what the CFM and ampage load are for this.
Last thought, boating companies sell 3" and 4" bildge fans. I run one to each side of the car and flow air out the louvers. This bring down the heat under the hood with a 20F drop. Hood needs to be sealed for this to work. Rap the exhaust with heat shields and hi temp raps. Again helps drop the temp under the hood. I have run the raps for 16 years, the pipes are still fine with no rot out holes. They where hi temp coated from ERA. Good luck, Rick L.
