Re: What about the 25K 105mph V8 Patrician?

It is grossly irrational to make ANY comparison or analysis between an engine used under SUSTAINED operating conditions such as SUSTAINED speed, SUSTAINED temperature etc to any engine operated under wide and varied conditions.
The 105 mph IS impressive relative to even modern high speed operation. That's what the engine was built for!!!

There may have been a few exceptions such as a few people out west that may have been able to SUSTAIN very high speed operation in a climate that SUSTAINS even high temperatures. THose would be the only engines that could be compared to the test engine run by Packard.

So the Packard proving ground test was a SUSTAINED high speed test and NOT a valid shakedown for real world operating conditions of the general public.

LEt me put it another way:

I would completely expect ANY engine operated under SUSTAINED operating conditions to out last the same engine operated under normal public use operation by a factor of at least 4.

So in the Packard test i would expect the enigne to run 100K miles before it needed ANY internal engine maintenace while expecting failures in engines at 30K miles operated by little old ladies that only drove the car to church on Sundays.
