Technical ***August 2023 Banger Meet Thread - Sleepy Days of Summer***

From my understanding it is a little more involved then that. Apparently you must reregister the car in the different class (Pay money), change the car number, and go through inspection again. But my understanding maybe incomplete. I believe John Nielson maybe a better authority on this matter.

 

No, you're right. But you can run maple syrup, piss and/or gasoline in the fuel class.

Don't listen to Nielson, he's a rookie at this.

 

....or - put a nitro tablet in the tank, ala World's Fastest Indian LOL

 

Yea, ya gotta do the extra paperwork to make the gods happy. I was referring to changes to the car itself.

 

Well, you're running a "different" car in a class after you've run in another class. I don't think that's so big a deal -- we never did it. But it's worth keeping its runs separated. And, it's not full price, is it"?

 

Stan
For you a class change will be full price plus a pia charge
And remember guys, fuel is for those who cannot get gas to run
The entry computer codes must correct to correlate the speed/record data and that may require a reinspection

Ford dynamically balanced their crankshafts prior to counterbalancing them in late ‘32.Dynamic balance means the crankshaft is balanced as a rotating unit, Counterbalance is adding weight to counter the impulse from the power stroke.Find a good book on the four cycle gas engine function, it will help you understand how things work. Please don’t take this as an insult, reviewing the basics helps all of us, master mechanic, journeyman or apprentice

 

I would really like to see the book that claims the crank counterweights are to compensate for power stroke impulse.
Sorry, that B crank does not have counterweights on it
It is an example of the first cranks made for a model B motor
Those holes do not appear to compromise the unit
As long as not cracked it is serviceable

Never said the crank in the picture is counterbalanced. The counterbalance offsets the inertia weight of the piston/ rod, which does dampen some combustion stroke impulse..but hey, I defer to you, you are clearly the engine builder, I’m just an old mechanic.

 

Railcar
That sounds better, spell check must have erased the inertia part
Not that you id’d the crank as counterweighted, it is easy to mistake those for cw’s if you have nothing to compare to
This is all learning for everyone alike new and old
All good, J

 

I’m sorry I referred to the portions of the crank that are drilled as counterbalances. They are clearly not counterbalanced. I do not know what those portions of the crank are called that are drilled.
Thanks for the term dynamically balanced as I didn’t give it thought either.
I’m not being a smart ass but sincere.

 

Asking questions is how we learn
No harm in your questions

Ford dynamically balanced, meaning the the crank was spin balanced prior to assembly.. Ford began counterbalancing 4 cylinders in late ‘32..in actuality only achieving a 40% counterbalance.. The Burtz is counterbalanced 100%…According to those smarter than me..

 

They just keep multiplying. Picked up a complete B engine, a B transmission and a counterbalanced crank. The block the crank is in, is no good. If I’m lucky the block from the complete engine will be good. It also has a counterbalanced crank.
