Coolant flow
Alright, last time around for me.
YouTube is not research. It never has been, it never will be. It’s entertaining, it occasionally has decent info, but for every piece of good info there’s 10 that are totally wrong or misleading. “Researching” on YouTube just reinforces what you already believe, it’s not about learning.
I never said you were stupid. And I never even said that colder intake air temps don’t make more power. What I said is that application matters, and maximum horsepower isn’t the best tune for every application. The NASCAR example shows this clearly, they are tuning for other parameters. Is NASCAR stupid? Nope. Am I going to tune my street car to run 300° coolant temperatures because those engines make more power than mine? Or course not.
Pro-Stock runs for 10 seconds at a time and they get enough time in between runs to chill their temps again. That’s why they do that. If they ran for an hour at a time or had to make back to back runs they’d do something totally different.
Which has been my point the entire time. What Pro-Stock cars do has no bearing on how you’d tune a street car. Pro-Stock isn’t gonna work in a traffic jam on the freeway.
After all, there’s probably a good reason you don’t tune for 100° right? Even though it would make more power?
If you’ve never tested a pump gas engine past 165°, then what proof do you have that it works better than what I’m doing? I know exactly what the theory says, better than you can imagine.
Will it make more horsepower on your dyno? Sure, it probably will. But how much? And how will that change the drivability? If you’ve never done it any other way as you just said, you don’t know either.
See, even your challenge tells me where you’re coming from. I’d drive my car anywhere in the US, no qualms about putting 2,000+ miles on it because it would make it, I drive more than that every year. The fact that you’d load up an engine and haul it to go that far makes it really clear what you think your engines will and won’t do.
I’m sure my engine would make more power on a dyno tuned for 160°. And I’m equally sure that the handful of horsepower I lose on the dyno at redline isn’t worth running that tune on the street the way I use my car.
There are a lot of ways to tune am engine, max power is only one, and whether it’s best or not depends on how you’re using that engine, how that engine is built, etc, etc.
One more time.
I have tested higher coolant temperatures with pump gas. POWER LOSER.
Here is something to ponder. Think about this BEFORE you reply.
If hot(er)coolant temperatures were the ****, don’t you think Pro Stock could just as easily (probably much easier) HEAT the engine before they made a pass?
Dont you think that maybe they have tested it? Or do you think they are ignorant about coolant temperatures to the point they haven’t thought about it and tested it?
I damn sure know that Reher-Morrison has tested it because he wrote about it (more than once I believe). And they could just as easily heated the engine IF it made more power.
Or they are just dumb sonsofbitches who haven’t left the 1980’s.
Or maybe, just maybe they have tested it and they know cool(er) engine temperatures makes more power.
So think that through.
Of course an OEM isnt going to produce a cooling system capable of maintaining 160 degree coolant temperatures because they couldn’t give a **** if they give up 30 or even 50 horsepower because the vast majority of these engines never see WOT power. Plus the cooling system would be much bigger. That costs money.
Plus, you don’t know (unless you have opened up the OE computer) to see how much timing it pulls to stop detonation or whatever other measures they use to control detonation.
Again, unless you think the entire Pro Stock class is brain dead there is a reason they chill the engine to 70 degrees. They could heat it to 200 (or higher) IF it made more power.
Could we do that (cool the engine as cold as Pro Stock does) on what we drive? No chance in hell. The cooling system would be outrageous.
But we can drop the temperature from the blessed (and wrong headed) 190 degrees and make power.
Youtube is a great resource IF you have the common sense God gave a pumpkin. Ignoring it is foolishness at a juvenile level.
And as I type that, Uncle Tony has dropped another horrible video about heating the intake manifold to fix his piss poor carb tuning.
FMR. That’s BAD YouTube, but you should be able to deduce that.
