My car runs 15 minutes every morning in the winter until it reaches operating temp when it's cold winter time. Then same on way home from work. Thats 30 minutes a day, for 60 days between oil changes, that the engine is ran without being warmed up to max operating temp. Hour wise, that's 30 hours. How in that 30 hours of COLD run time, does that engine not even consume a quart of oil, even with 142k miles on the engine? They are doing something right , just not sure what lol

I agree with you big AL, (even thou nobody else does around here ) Cold engine is no good. I`d like to build some heat but how is that going to be accomplished with no thermostat provisions, I haven`t figured that out yet.

Back to a question I had earlier. What do the oems do for ring gaps in aluminum block engines that are subjected to -20 or even colder ambient temps? I'd imagine there has to be quite a bit of expansion going from -20 to 210*.
Tighter fitting Hypercracking pistons with high ring locations. Electric fans and other mods to get coolant temp up not just high but quickly. Also oil coolers fed by coolant whicvh heats up faster than the oil.

Thanks Danny... as I said I run both stages in... and it was a pain in the ballz makin any heat... but big HP engines need water volume... and my dilemma was 1 stage not enough and 2 stages too much so.. trial and error is the only way my friend.. there are so friggin many variables such as, pick up styles, angle of pick up, hose diameter, style of oil coolers used...and the list goes on and on...

for starters they're not trying to make 1000hp and make it climb a 75 degree incline for its entire life!!!

Nah, I'm good. And there's no way I'd throw a 330 into my beloved Formula!

There are a lot of opinions that's for sure! This isn't the first engine that I've built, though I have been just a little on the overly cautious side of things with this build. I want it to run well and produce some impressive power, and have it last. I've taken everyone's opinions into consideration, and come my own decision on what's appropriate, I will say that along with the opinions comes a lot of overthinking! I had to shut that side off a little... I found myself starting to go a little crazy from it!

Really enjoying this thread!

I won't post how HOT I run mine because I don't wanna put up with all the bullchit replies I'm gonna get!!! but what I will say is that back in my Funny Car days.. I wouldn't stage the car till the temp hit 290 to 300 Deg F... what's that tell yaw'll?

if an engine makes more power with hot coolant i wonder why nhra pro stock engines run 100 deg f.maybe they don,t know what they are doing,those 500 cu in engines only make 1400 hp being n/a.
