With a Strange 60, lets assume 400HP at the FW, since 273's don't normally require them.

Most assume 20% drivetrain loss to the rear wheels.

Lets assume at highway speed you are using 100 HP average at the FW. That means you are "wasting" 20 hp thru the drivetrain and rear tires. If car is manual, I'd guess 5% (high?)loss there in tranny, and I'd guess 5% loss thru the rear tires. Lets assume no brake drag, and u joints zero drag ( ever felt a hot one?). That means 10hp is getting used up in Rear end. 1Hp equals approx 745 watts. That mean a big hunk of metal, with restricted air flow, fairly compact, is being heated internally by a mechanical heat source equal to 7450 watts.

Why would you expect to be able to put your hand and hold it on a piece of metal heated for an hour by a 7450 watt heater?

You can plug in any of your own numbers and likely get a different result, but I think I made my point.



Edit above assumes a properly operating rear end

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
