Automotive engineering...in spades!

Automotive engineering...in spades!

RE: Automotive engineering...in spades!

What a sad attempt...

RE: Automotive engineering...in spades!

It is supposed to be "sad". The 24hrs of Lemons is a bunch of people racing poor excuses for a race car. It is more about fun than money. I believe one entry this year was a modified E250 van.

I believe that's "LeMons."
 

RE: Automotive engineering...in spades!

not sure what you mean, I didn't call it Le Mans.
 

RE: Automotive engineering...in spades!

My favorite feature of LeMons is the prize for the "Index of Effluency".

RE: Automotive engineering...in spades!

"Index of Effluency".  Is this awarded for LeMons or Le Mans?

Just to show more of my ignorance of auto racing:  While a teenager (many snows ago), I saw a poster on a telephone pole advertizing a "Grand Prix" local race.  I read it out loud mispronouncing the "x" as "cks".  My freind and his older sister were riding with me.  They had a good laugh at me.

RE: Automotive engineering...in spades!

Made the same mis-pronouncement when I was about 7ish... my brother thought it was a real hoot at the time.

OK, I'll bite.

The gear ratio on that starter pinion and flex plate ring gear is around 15:1.  That turbo compressor won't begin to achieve any measurable P/R (or boost) until about 50,000 rpm.  Especially with the compressor inlet located in the turbulent, low dynamic pressure zone created by the  trailing wake of the drive system.  At 50,000 rpm on the compressor shaft and a 15:1 drive, the fan would need to turn at around 3333 rpm.

Maybe someone with an aero background and a sense of humor would be willing to explain why those 15" fan blade airfoils (hand cut from a sheet metal A/C duct no less!) would be unlikely to achieve a tip velocity of over 430 ft/sec in a 65mph airstream, against a several horsepower shaft load.

The lesson here kids is that if you want to be successful at perpetrating an urban myth on the internet, at least make an effort to get your technical facts straight.

Clearly, what's needed is an intercooler... see attached  (hope I didn't grab this off EngTips, I don't think so)

I regret to admit that it took me more than just a second to notice what was wrong with the picture.  In fact, Pat had to point it out before it hit me.

Judging from what I can see, there's one minor part missing.. the turbo.. :<)
