Low temp thermostat

[Mike Rolica]

Geez,  I guess everybody is smarter than all them engineers at ford gm and
D.C. that spend millions of man hours designing automobile engines.  
Kinda funny that most cars use 190-195 deg thermostat.  Them engineers musta
picked a number and stuck with it for no reason. With all the advances in
engine tech of getting more power from each ci, I guess they coulda just
saved a whole whack of money and put lower thermostats in a car.  My
experience with oval track motors, 185-195 makes the most power no matter
how you jet/rework the carb at 165 deg.  With over 1000hrs of dyno testing
done on these motors not once have I seen one make more power with 165 water
temp.  Things are done for a reason, and emissions is bs. Why do late 60's
cars use 195 deg thermo, They obviously were not concerned when they built
ma pa's 1967 chevelle, 396,375hp bbc. (8mpg).
You may say then why can you get more power than stock motor?  Probalby
because the stuff that makes real power is allot more expensive, ie porting,
supercharging ect and not production line cost effectrive. They have to work
with production line/mass production tolerances.  All motors have a saftey
factor built into them, so that there is less chance of faliure.


COST COST COST is why 350chev don't make 400hp out of the factory.  If
changing a $2 thermostat made 30hp, I'm sure they would have already done
that! And they could have found some way to cut the extra emmisions it made!

Just my view anyways.  Have read them kids mag.s before, for people that
know squat about cars but like to think they do.  I know a little bit, quick
fixes I just think about it, ask why would the guys that know allot
(manufacturers) did not do that, and try to  come up with a reason why. Most
of the time it is because it is BS

	Hmm...I'd have thought in a PFI car, the concerns would be more of
thermal 
	expansion and not atomization since the FI's are really spraying at
an open 
	intake valve? I can see your point on a TBI or Carb'd car however. I
mean, I 
	know an engine runs more efficiently at high temps, (I remember an
article 
	where Smokey Yunik got 400+hp our of a Pont 2.5 and it was ultimatly
a zero 
	emissions engine (like 95% efficient) Cuz it ran hot, and used the
heat to 
	preatomize the fuel etc. Was pretty neat article. Was in an old
HotRod or 
	that type of mag.) But'd make more POWER at low temps, or maybe I
should 
	reiterate, at low CHARGE temps.
