There is enough air flow to match the fans running high speed. The big thing will be what angle the radiator is set at and maybe having a splitter to help bend the air into the radiator better. This is a test you can do at home with a $10 piece of aluminum. The new cars only turn on fans when speed is slower than 10 mph or the pressure readings get high. The other thing if you are in stop and go traffic crack the back of the hood to help move the air out from under the engine compartment. I have seen a small block of wood rapped in soft cloth to protect the paint. I am testing small bilge fans that blow air out the fender vents. They come in 3" & 4" sizes. The amps for both is 15a. I have them on a relay and switch for racing. seem to bring temps down under the hood by about 10-15 degrees. I have not used a temp gun for this test but is funny to see people jump from the hot air coming out the sides. I cooler or more fresh air I can get in and out from the hood area has to be worth something for cooling the motor.
Watch your charging system at idle with a high amp fan. I don't know if you have a volt meter or amp gauge. Would not push a amp gauge with a steady amp load of 50-60 for hours. It will melt the insulators over time. I have gone to an 95 amp system from PAperformance that is a bolt on and a 1 wire change. It leaves all the other wires in place if you want to switch back.
I would add the volt meter either way and just connect the 2 main wires off the amp meter togeather. You can add a small wire for the volt metter at this time for the signal wire. All you need is a ground to get the correct readings. Rick L. P.s. watch the amp loads on these fans, they have a FUDGE factor of about 10% high or low. Summit sells a shroud kit for about $100.00 and needs to be trimed to fit. Its aluminum and can be polished or painted black to hide if you want. I like aluminum for spraying WD-40 is the only cleaning I have to do. I hate maintainance work like this.
