Coolant Temp/Syn Oil

[fahrvegnugen at cox.net (David Utley)]

Drag-racing is not a direct comparison in my minds' eye.  One hot run or a
few, vs. laps and laps...  Not to mention, most 1/4ers use something higher
than 93 octane, and are built for one purpose...

BTW, you won't see an SAE paper on Evans.  I would imagine that SAE papers
are NOT written with the idea of endorsing any particular product, no?  Come
on Larry, you gotta TRY to think outside the box, at least occassionally.
The universe is not a cube, ya know?  ;-)

 Anyone else here on the list who uses Evans, and feels there is more power?
I know Larry, just conjecture, no dyno-sheets that are easily scanned and
viewed via the web, etc...  However, I am willing to bet that those who have
it, like it for the reason already mentioned...

David

PS--  Why is a violent burn out of question to produce more power?  More
BANG for the buck?  If I put in Alcohol, or even say 110 octane in my car
right now, it will run like a motherfuckerfromhell.  Yeah, it will kill it
since it was not designed for it (and since it is on its last legs...).

I wasn't arguing the higher-coolant-temps-equals-more-power (in my mind, the
jury is still out...way out...on that one),  I was arguing the
violent-burn-equals-more-power statement.  So, the Evans site is N/A, as far
as that discussion goes.

 Just remember, the Evans site is an advertisement, not an SAE paper.   :)

Oh, yes, one other thing:  if hot fuel makes more power, why do drag racers
ice their fuel lines in cool cans?
