**In like a lion, out like a HAMB** March 2013 Banger Meet

the name balance tube says it all think about it no expaination needed surely

 

C20

All WORKING SU's pairs ot tripels have some sort of tube

Just cause you can't see it doesn't mean it's not there

 

To keep the SU tucked in under the hood I made a 3/4 thick alum adapter and run a 1/2 ridged copper tube between about 5/8 OD. The OHV run awsome very smooth no stubbling, great thottle response.

 

Bill,
Is that your SBC head conversion?

Thanks for the follow ups, I would to know the physics behind the "requirement" for a balance tube. But that is just me. I can snake a copper line under my exhaust manifolds.

Has anyone seen a source for the ball rods ends?

 

More pics of the Bowtie OHV conversion....PLEASE!?!?!?

 

Talking about wheels, anyone know if someone makes support adapters to use steel wheels on mechanical drums?


I am still waiting for my spindles to be reamed at my buddies front end shop to reassemble my front end, install my reverse eye'd t rear spring and paint my chassis. After that the engine gets pulled for modern valves, large tappets, porting, flywheel lighting and to install the cam.

Cam choice suggestion from those in the know. I will be running two 97's for now and am tinkering with a triple 81 intake for later on, stock size valves on this motor (motor 2 will have large valves), 6:1 winfield head, porting, fsi distributor and a lake pipe. I currently have a 335 lift 280 duration cam on the shelf but am thinking that I may be lusting over a 340-355 lift... Any thoughts?

 

why adapters ? if you use 5 on 5 1/2 they bolt up . used several & no problems .

 

Just wanted to make sure since the face of the drum has a different shape the the juice drum. I always assumed it would cause an issue. Glad to know it wouldn't.

i did use flat washers glued over the studs to make it even . sorry i forgot that ! i ground one side flat to fit the hub , then glued them to the hub so they stayed where i put them . 10 yrs with no problems ...........

 

The mechanical drums do have raised support areas that I believe will interfere with proper bolt up of disc wheels.

There was a post on the Fordbarn not too long ago about steel wheels. One person commented about using WW2 jeep wheels as they have a larger center hole so they fit the model a drums better and give more stud threads.

 

Dang I lost everything I just typed!!
Yes thats the SBC head conversion.
I have fuel injection for it now and started to work a little on it last year.
It run very smooth and strong, revived very easily. I did not have a tach for it but I could get rubber in first and second and a chirp out of third and could bury the 80 mph speedo very quickly and just keep climbing fast to the point you feared getting out of control.
I hope to get this and many other projects running again once I get moved to Kentucky and get my shop set up.

If anyone is interested I can try to dig up some more old pictures. I was 19 almost 20 and worked over a year on it completeing it at age 21 so I don't have too many pictures.
I feel a little sad now that I just turned 60 and it sat on the self all this while.
Time goes by so fast when you have a family and have to work hard to make a living.

 

Red Rocket I would love to see the pictures inovation is what we are here for if you can post them im sure many of us would love to see them

 

Russ,
I will look for some pictures when I go back home this Sunday to Kentucky to visit my wife. We moved all the house stuff and pictures january this year. Other wise I could try to take some of the engine here at the shop it is tucked under the bench here in Wisconsin.

When the steel wheels sit on the wire wheel support rib on a Model A hub , in my opinion there is not really enough stud through the wheel . I can only get the nut about half on..... there should be at least one thread showing outside the nut when it is fully tightened. The Model A studs are swaged into the hub so I imagine they may need replacing with longer studs...maybe the 42-48 studs?? or you could have a separate set of hubs and drums to use with each type of wheel...or machine the support rib off and use the rings when the wire wheels are fitted.

 

Was there enough thread left on the studs to come all the way through the nuts after you glued the washers on?

 

No the balance tube is to keep the carbs balanced/synchronised across the entire rev range. To minimise the effects of intake valve openings in the firing order, and therefore keep both carburettors admitting the same amount of fuel/air to the engine as you open and close the throttle.

SUs ( and CD Strombergs) are constant depression carbs, the piston is raised by the combination of air flow and the difference in pressure(depression or vacuum) on the engine side of the throttle plate ( butterfly) to the atmospheric side of the plate....
When the throttle plate is opened the piston raises and lifts the needle in the main jet thereby allowing more fuel to mix with more air
Without a balance tube,the slight differences in ring and valve sealing and compression etc from cylinder to cylinder will allow the carbs ( and therefore the mixture ) to fluctuate . It is more noticeable at low revs, just off idle, but it affects the balance(power) right across the rev range.
With the balance tube ( which should be about half the cross sectional area as that of one intake manifold) the engine will run much smoother and make more power.

I'd love to see more pics of the conversion, and learn more about what you had to do to make it work.

 

97, Brilliant! . That is exactly what wanted to know. I think I will build the intakes, pipe thread a port on the bottom of each one, make up a tube that runs under the headers between the two carbs.

Thx!

Did you get that information from a website (I've been searching) or you just smarter than me?

 

Red Rocket
I just turned 61 years young and am still working for a living. I know what you are talking about, all us small business owners are getting RICH right!
That said I'm going to slow down a little and smell the 4 banger exhaust.
I'd love to see more photos of your creations as time allows.

 

Here is more on Bill's SBC head:

Well I went through my old pictures and not anything worth sharing on the OHV that I could find in my pictures. I will try to take some more detail pictures when I get back on it again. sorry I hoped to find some old polaroids.

 

Red Rocket would you mind telling us about some of the other banger projects you have been involved in since the building of that head a lot of experience between then and now and I am sure a lot of lessons learnt

 

Red Rocket... when did you and Cindy get married?

 

No we didn't really get marryed but after 15 years I think it called common place? anyway after 15 years it feels like we are marred! LOL.

 

As we start our autumn here to the south spring fever should be taking hold to the north. The young bucks should be bringing their new rides out trembling to go in their finest new season plumage ready to impress the younge chicks with their plumes of smoke their roaring and the booming beat in the early spring evenings in other words show us what ya built over winter lets see a bit of spark and colour in this banger meet no stodgy winter gloom

 

Jeez that was deep Russ . I heard you SOLD some stuff from your horde at the SS swapmeet. ...wish I was there.!!

 

haha secrete project agent 97 besides banger meets seem to be dead of late same old same old know what i mean how do i put wire wheels on later drums or what carb fits a model a motorho hum why do we post banger basics

 

Not a very big secret, I was talking to Gerard ,he told me he bought parts from you.

Yes but surely that is really one of the main reasons the banger meet exists , so that new guys (to bangers) can find out "how" ....it would be nice if they beleived the experienced guys when the info was freely given, though.

Maybe we should twist someone's arm for a complete buildup of a "winning" hillclimb banger....
or you for a Rutherford buildup. .....
or ???????????
