445 NM bei einem Benziner

Nachtrag: Oder habt ihr da den Scarlet 7Si? Dazu steht in den News nur: "Scarlett 7Si is now available. 137 HP version of our 7 cylinder engine is ready for you." ... aber leider nichts zum Drehmoment.

I dont fully understand everything that was written above. This is the last of the 137hp versions that has the 445n.m torque. Verner has standardized all the cylinders on the 3, 5, 7 and 9 cyl engines and the new 7 cyl are now only available in the 124hp version.

@Kitplanes:

I only questioned for the engine Oliver meant. Looking at Verner′s webpage I found:

• 7 cylinder Scarlett 7U: 124HP, 390Nm torque
• 9 cylinder Scarlett 9S: 158HP, 485Nm torque

He talked about 445Nm, so I questioned which of the engines he suggests.

Searching the News of Verner I found a new Version of the 7 cylinder, the Scarlett 7Si. Maybe thats the engine Oliver is talking about because of 445Nm?

That is correct, I bought the last production 137hp engine.

7 Zylinder --> Verner Scarlett 7U --> 390Nm Drehmoment und nicht 445Nm... daher auch meine Frage, die sich ja jetzt erledigt hat. Die bauen den neuen Verner Scarlett 7Si ein.

Und weil gleich Wochenende ist:

DEDICATED TO ALL WHO FLEW RADIAL ENGINES

We gotta get rid of those turbines, they′re ruining aviation and our hearing... A turbine is too simple-minded, it has no mystery. The air travels through it in a straight line and doesn′t pick up any of the pungent fragrance of engine oil or pilot sweat.

Anybody can start a turbine. You just need to move a switch from "OFF" to "START" and then remember to move it back to "ON" after a while. My computer is harder to start.

Cranking a radial engine requires skill, finesse and style. You have to seduce it into starting. It′s like waking up a horny mistress. On some planes, the pilots aren′t even allowed to do it...

Turbines start by whining for a while, then give a lady-like poof and start whining a little louder.

Radial engines give a satisfying rattle-rattle, click-click, BANG, more rattles, another BANG, a big macho fart or two, more clicks, a lot more smoke and finally a serious low pitched roar. We like that. It′s a GUY thing...

When you start a radial engine, your mind is engaged and you can concentrate on the flight ahead. Starting a turbine is like flicking on a ceiling fan: Useful, but hardly exciting.

When you have started his radial engine successfully, your crew chief looks up at you like he′d let you kiss his girl too!

Turbines don′t break or catch fire often enough, which leads to aircrew boredom, complacency and inattention. A radial engine at speed looks and sounds like it′s going to blow any minute. This helps concentrate the mind! Turbines don′t have enough control levers or gauges to keep a pilot′s attention. There′s nothing to fiddle with during long flights.

Turbines smell like a Boy Scout camp full of Coleman Lamps.

Radial engines smell like God intended machines to smell.
