I would think both, we all know that too much heat will steal power..

More to it then that — practices gave a base and we had different fuels tire compounds and height adjustments - so we could adjust a bit not much other issue was - an engine only lasted one weekend 12 races gets expensive

but 3 USA championships in 5 years broke me - rider was 36 they told me go find a 18 year old and they would get Sponsors - but he was the reason we were doing as well as we did - getting it to go was 1/2 — riding what we did took a lot of talent was the other 1/2

Not to belabor the point, but, fan driven coolers, either oil or on the heads don't do much above parade speeds. That's why cars had thermo-clutch fans before electric ones, and electric fans have thermostatic switches. 100mph air will cool the motor without a fan assist, and the fan may even impede airflow.

My super gas nova had a 6 blade electric fan and water pump and it would on gas 230 at the traps - took one of at a time ended with 3 and 200 at the traps @150 mph / 160 depends on temps but in the cold as we dialed the same et it is was not an issue but car was faster in the cool

Not sure if you are saying it was cooler without the fan or with 3 fans? Actual practice beats theory. Thanks

Radiator electric fan - I removed 1/2 the blades and the car speed took over as it the air we feel was not being blocked as much and the electric water pump is the same so nothing changed in the water movement / temp while going in a straight line and hi speed - changed 30 degrees in a 1/4 of a mile but 720 HP was in play

the nova cutting air is like having a big refrigerator but the grill front is always the. Same doing the same thing

I’m fine with just cooler when moving. It’s the stop or traffic jam that causes the excessive heat… hence fan.

Just a thought something we found - the temp of the fuel in a carb bike is the thing most affected and yea oil temps but most oil good stuff will still be doing the job at over 300 degrees some almost 500

i did use a 12 volt computer machine type 4/12 inch fan we did have a GSXR front fairing made duct to help both sides and on the track in play we seen 25 degrees difference in the temps of the fuel in the line in the heat cover - so yes in my case it did what we were looking for cooler fuel

engine temps were what they were but i used 10 / 30 Mobil 1 oil anyway with no additive - wanted nothing to be an issue on the flywheels to see water up at its knees only at the bottom of its feet - not one time after a race did i see oil as a issue causing damage - ring chatter sure we were always close to the 56,000 feet per second piston speed - valve spring becoming weak 10 pounds off its install pressure - piston squirter we developed from the lifer feeds one or 2 becoming partial clogged yea never totally - flywheel scraper adjustments being every race we could see on the tail computer in action - and the classis dyno having a time element using 4th gear only from engagement to red line tells the real story w/ speed of torque

many ways to make power the real deal is in keeping it alive - while beating its brains in - the south was the worse 100 degrees at 8 am yea i want to do this if it could talk

That’s some serious ingenuity. You guys did some cool stuff.

@johnjzjz
The way I understood your statement about the fan blade reduction was that at speed it was actually decreasing the amount of air passing through the radiator and by removing blades the speed of the car actually moved more air across it.. Correct??
