HO-HO-HO December monthly BANGER meeting

good morning , im late but interested . im building my '31 to "pre-war" correctness . thankfully it is not that far off . i would be happy to join in on the meetings , if ok .
hope to be on time next month ............... steve

 

I got a little ahead of myself, the intake length calcs will have to wait until I get the cam...which is going to be next year sometime. To do it, I have to have the intake opening and duration, as the sine wave is based on the open time and duration of the intake valve, so no point doing that just yet. Probably will do the intake volume and work on the ports.

will try and come up with something useful or fun this week.

 

Started on a new project (speedster). Bought a frame a month ago, and an engine almost 3 months ago. I'll hopefully get a bit done over the winter break. I've currently got 3.5 transmissions worth of gears to pull the best set from. Also gotta reassemble the rear, and actually start laying out a body. And finish assembling the engine . . everything is just kinda hanging on for the pictures.

 

Cool.

Keep the updates coming.

 

Steve Norcal your always welcome, the more the merrier


Post some pics of your banger and ask all the questions you like, no one bites here...

my avatar is my car . its apart right now getting a new motor,trans,& diff . will be together soon , i hope ... thank you .............. steve

 

I posted this in outside the BANGER meeting, no response yet so its either a stupid question or no one has put a multi disk clutch in.

"My 1928 Model A AR has a multidisk clutch when I pulled it down I found it had no pilot bearing fitted. I have had no luck looking in parts suppliers catologs as they only list the bearing for single plate clutches.
Should it have one?
Will the later bearing fit?
I could turn up a bronze bush, anyone been here?"

Thanks

Here is an article on restoring the Multi-disk clutch.

Info from MAFCA says you should get rid of that multi disk clutch if you want to drive the vehicle. It also says there is no pilot bearing in original design. read more...

 

has anyone else got photos of engines being built similar to the marvellous pics posted of crazydaddyos dad motor i find so much of intrestin these i would love to see details of mag setups and oil pumps particularly front drive types

 

Try this link:

There is a lot of neet Banger engines.

 

thanks crazydadyo often view this site speedy bills collection aint it neat stuff i think modern bangers have developped a different look still good but more commercial less hand made maybe but its good to see folks doing the calcs my be someone will do a two up two down motor as done by Ed Winfield now woudnt that be something to hear good to see the hobby is alive and well here.
No posts by Bluto lately interesting man?

 

I hear in the wind that there is going to be a new write up on the winfield 2 up-2 down motor along with it's recent restoration, and the reconstruciton of the car that it was run in. All this to a door step near you soon.

I miss bluto too, always something fun and interesting to ponder.

 

that engine would be right in your line imagine the calcs on that intake manifold

 

While I know that what is being discussed regarding carburetion is rather exotic with the all the mention of sine waves and such. I will pass on to you a couple of old formulas for carburetor size. Formula #1, divide the cubic inches by the throttle bore size, 50 for a fast street engine 40 for competition , circle cars and such, 30 for lakes or strictly top end. By this formula I'm under carbureted on my 2 port
Another from an old race car driver engine builder is for circle cars 1" throttle bore for each 50 inches displacement. Notice, these are speaking of throttle bore not venturi.
These are the old standards Throttle bore is Diameter X Diameter X .7854.
Now, hows that for trivia?

 

Merry Christmas everyone

The 5-main came with bearings in it. Their OD is too large the saddle bore go thru the caps into the stud holes. I am going to make new caps that retain the top half of the old bearing. We will borethe new caps and old bearing half to the new main bearing O/D Thus the old bearing acts as a spacer with crush and cotact. AND tranfering the heatt the block almost as good as a single bearing shell in place

Once the crank turns I'll design con rods and new pistons.

Really need to get the dry sump system together too.

We are bringing in th Miller next week and completely strip it.

So that's it for now. Photos next month I hope

 

Interesting formulas in that they don't lead to a under carbed situation.

The first one I'd say is a little too much but the the second seems pretty good.

For a 200ci Banger you'd need 2 x 2" carbs. Shame I got rid of my 2" SU's.

Speaking of formulas. That Stromberg/cfm one that constantly gets put around is so far off the mark it hurts!

 

yes, it is definitely the reference that I am using. Not the most efficient, but I am going more for the looks/period (and some function)

 

i never have come up with a good one, the only one I have is for CFM, and I have yet to come up the CFM for a Winfield V/M or a Master.

 

If things go right I will increase my dual Winfields to "C""s for the Antique Nationals next year. With "BB"'s the first formula figures to 48.2. With "C"'s it would be 41.5. This formula came from a Hot Rod Magazine from the late "50"'s or early "60"'s Formula #2 would take 4 81's or equivalent to give total throttle bore required. 2 "BB"'s total throttle bore area is 4.15 rounded off. I read some where that Ed Winfield had said a "B" flowed around 120. This could be a senior moment though, may be wishful thinking.

 

Good to hear from you this month. I was wondering how you were. I hope your health is good?

I am anxious to see the Hall finished.

.

 

So what are the true cfm ratings for the various Strombergs?
81?
97?
.

 

Whilst we are on the stromberg subject,what jet sizes do you guys reccomend for a single 97 ive got 43s in at the moment but might go a little richer.
Happy Holidays
Nick.
