UPDATED life goes on bra

[Paul]

here's a little Dolly Partonesque tacky tech fer ya,

form an idea stolen from fellow HAMBers, twist the idea around a brain cell or two,

assemble some junk you got laying around,

a swap meet BBC intake, a pair of old Holley carbs, some K&N aircleaners and Aunt Bee's cake covers?

[Paul]

trim

[Paul]

fit

[Paul]

tack

[Paul]

try welding, give up and use some aluminum solder you had laying around for twenty years..

[Paul]

file and try 'em on!

[Paul]

for my next trick... http://www.jalopyjournal.com/ubbthreads/images/graemlins/tongue.gif

I think you need to find some bigger pans! http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

[30tudor]

Nice pair. Looks like centerfold material to me.

[TINGLER]

Wow! thats pretty cool.

It would be cooler to have actual pans with the handle still attached! he he...

Here is a TECHY question about your post.
How well does those little air filters flow? I wanted to use one on a 4v carb I have.....but I am worried that it will not work right.
mine is something like 6" in diameter. How much of a difference will it make compared to a 14" or a 10" air cleaner?

Hope I haven't jacked your post. But this question came to mind from looking at your WAYYY COOOL air cleaner. Seriously, I like it!

VonTingler,
I was actually looking for some that said CAKE on them but these were the first two matching ones I found.

I don't have my calculator with me but these are 4" tall if you want to figure rough area, and the K&N stuff does flow pretty good.

Paul

now that I think about it, I will tap the plastic handles and see how they look for top nuts..

The K&N's flow great, I would think that a K&N of that size would out flow a 14" paper element.

VonTingler:

From the K&N website:

Use the formula below to compute the minimum size filter required for your particular application. The usable portion of the filter is called the EFFECTIVE FILTERING AREA which is determined by multiplying the diameter of the filter times Pi (3.1416) times the height of the air filter in inches, then subtracting .75-inch. We subtract .75-inch to compensate for the rubber seals on each end of the element and the filter material near them since very little air flows through this area.

A = (CID x RPM) / 20,839

Where:
A = effective filtering area
CID = cubic inch displacement
RPM = revolutions per minute at maximum power

Use the following formula to determine the height of the filter.

H = (A / (D x 3.14)) + .75

Where:
A = effective filtering area
H = height
D = outside diameter of the filter
3.14 = pi
0.75 = the rubber end caps

If you run through the math, Paul's filters are a smidge too small for his BBC.

Ok, 454 BBC, max RPM 6,000

A = (454 X 6000) / 20839
A = 130 in^2

He has two filters, so each one must then flow 65 in^2

H = (65 / (6 x 3.14)) + .75
H = 4.25 in

I do have a question for ya, Paul -- where does one go shopping for cake pans? Thrift shops?

Ed

[Fat Hack]

You can score cake pans like that at thrift shops, dollar stores, garage sales and flea markets...the trick might be trying to find TWO that match, though!!

Check out this 1/25 scale version goin' onto my 65 El Camino! http://www.jalopyjournal.com/ubbthreads/images/graemlins/cool.gif

[TINGLER]

Thanks for those facts and figures! I'm gonna mess around with them and see what I come up with...

FAT HACK, where the hell did you get 1/25 scale CAKE PANS? Did you raid BARBIE'S kitchen?

KRAAAaaaaazy man...... http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

[Paul]

edmurder,

Thanks for the math, you might also want to include the filter thickness, as in the depth of the fold, ie; if you cut it apart and stretched the filter out it would be at least twice the circumference thereby doubling the area.. 'course if this is their math they must already be taking this into account..

..anyway that’s what I was alluding to when I said "rough area"

Like advised in another post; always be open to using available shapes (or something to that effect..) http://www.jalopyjournal.com/ubbthreads/images/graemlins/tongue.gif

I was not "shopping for cake pans" I just noticed a pair of matching shapes. http://www.jalopyjournal.com/ubbthreads/images/graemlins/crazy.gif

These I found one at a junk store and the other at an antique store, $5.00 for one and $6.50 for the other.

Paul

[DrJ]

That's a neat idea!
http://www.jalopyjournal.com/ubbthreads/images/graemlins/cool.gif
Go to a local restaurant supply or Smart & Final Store. They have stuff like that and you won't have to spend a day and a half polishing them.

K&N takes the pleated area into account for the formula. David Vizard's book "How to Build Max Perf SBCs on a Budget" has a formula for filter area based on engine HP. I'll check it when I get home to see how it compares to the K&N formula.

Ed

[katzenhammer]

Yeah nice idea! I suppose Bunt pans are out of the question...

sigh.

Justin

[Paul]

katzenhammer, now that's just plain silly!

here's an update for yuz-

I spent a couple minutes filing and bead blasted it and a crusty pair of old Cal Customs I had layin' around..

whudda ya think??

izzat the TITS or what!?!

[KCsledz]

That looks pretty frickin good if you ask me!

[burger]

Paul,

I have an update for you. The esteemed David Vizard feels that you have more than adequete filter area. He says that each square inch of surface area (flat surface area, not pleated surface area) is capable of handling 4 - 4.5 HP.

So then, if you have 2 filters with a 6 inch diameter and a 3.25 inch filter height (subtract .75 for the rubber), you have 123 in^2 of filter area. Here's the math:

A = (# of filters) x (3.14 x D x H)

Where:
3.14 = Pi
D = Filter Diameter
H = Filter Height


According to Vizard, your filters can support 500-550 HP, which would be a pretty stout 454.

......Ed........STOP IT! I'm getting a headache! (you "techies") http://www.jalopyjournal.com/ubbthreads/images/graemlins/wink.gif Next thing I know, you'll have Dr. Duck shouting, "E equals MC squared...."

Cool idea!!!
That style cake pan must have been very popular. I've seen at least a dozen of them at yard sales and antique stores.
