Another 273 commando build .. This one will be a "BEAST"

Heat of combustion is what powers your flywheel. It's been published that, of all the energy in the fuel, ~1/3 of it goes into the cooling system, and ~1/3 goes into the exhaust, leaving just ~1/3 for the flywheel. The hotter you can successfully run your combo, the more potential it has to make power. Your upper limit is the oil temperature.
Everything we do to our hotrod engines is an effort to create more heat in the chamber,to produce a stronger push on the crank. But only ~1/3 of it gets there. So we have to figure out ways to keep the energy out of the oil , and out of the cooling system, and out of the exhaust, without melting the darn thing.
Modern manufacturers seem to have figured it out;
the 2.4 naturally aspirated 4-banger in my Orlando is rated at 167Net hp at 6700. That's probably pushing over 200 gross. Not long ago 318LAs could barely muster 180crank, and 318s are over double the size of a 2.4 which is ~146 cubes! That's pretty impressive. One of the ways the Orlando does that is with 220psi cranking cylinder pressure. That's heat,man! That's a lotta heat.
Another way is by running the engine pretty hot, she hovers around 220 most of the time.
And the thing is over 3800 pounds with me and the wife in it, yet I have never thought she was under-powered. But I guess the 6-speed auto has something to do with that,lol.
Heat really is your friend, or better I should say CAN be your friend. .In the beginning I had too much. I had to back up and start over with looser pistons and bigger ring gaps. Then I had to sneak up on it.The reward was 93mph in the Eighth, which the Wallace calculator translates to 433hp,..... from a 367 cube Daily Driver. I run her at just 207*F.
