Darn Maths!! Next you'll be telling us that the 500 mile Class 8 Tesla Semi-Truck is a crazy idea... smoking smiley

Is it safe to assume that ALL electric fan threads should die a bitter death?

At this time yes.....

As previously stated.... They can be made to work 99% of the time with tremendous other mods....

NOT WORTH the hassle.... good for "conversation starters"...

I think the only right way to do an electric fan is a big stack of batterys in the trunk, preferably 24 volts and a motor that is actually big enough to do
the job, mounted forward of the engine on a long v-belt. It would probably only weigh 200-250lbs more for a generous range smiling smiley but the weight balance for the car would be nice and no power would be used by the engine for cooling and the fan could then be sped up or down based only on head temps, keeping the heads at a constant temperature independent of load and outdoor air temps.

It is always nice to hear about NEW ideas.

As has been mentioned electric has been used on very well deflashed engines but the kit I was talking about was being marketed for any street driven car! That is what prompted the testing that was done.

Trust me,Ken. I'm not about to argue with you or Bob.

In concept, with an efficient fan (one that will be efficient at the flow rates and pressures needed) driven by a powerful enough electric motor and controlled by a good variable-speed controller, which would be signalled by accurate and responsive sensors on each head, could do the job and even handle high power, etc. Trouble is, you'd also need an efficient generator (alternator/generating device) that would make enough power to drive that fan.
In concept, if you only run full power in short bursts, a suitable battery could handle the peak cooling demands. You would still need a generator much more powerful than a standard automotive generator/alternator.
But the cost of everything would make the vertical fans look inexpensive.

For racers for sure..... they have the HP to spare and cannot afford to overheat on High speed tracks...

But remember most V-fans do not cool well at lower rpm..... why Tom Knaublouch designed a new fan for them..

I believe the forced air idea would work well. Some scoops on the rear fenders or on the trunklid would get the volume needed. It would be good to have a damper of some kind to regulate the airflow, and not over cool, maybe like a bellows in reverse. Then a high powered electric fan or clutch fan. Way back in the beginning of my career, I made the cooling tables that were used for taping off the front of a Winston Cup car. The forced air at 40 miles an hour was enough to disapate 1100hp worth of heat. A cup car only made 710hp back then. So forced air at speed has quite a bit of capability.

Just for brainstorming purposes, of course -
Does Tom's fan work well at both high and low speeds? Does it seem that we still need either an improved fan or variable speed drive, above and beyond the best vertical fans we have available?
