Fuses for Circuit Protection

Gets real hot weather 100F in Oklahoma too.
Like Florida. Sometimes IL.
 
There is also another issue Rick.
Violent accelerating V8 Race engines on the street tend to shred V- belts apart.
500+ HP. Know Grumpy helped you pick a cam to perform.
Most of the time a 3-1/4", 4", or 5" diameter alternator pulley requied.
So the V-belt will survive.
Sepantine belts don't have same issue.
More surface area & more nylon or kevlar cords to take instant acceleration loads.
 
So to Sum up my thoughts or perspective Rick,
Its best to start with the Highest Amp Idle charge current alternator that will fit.
That way if you choose to use a large diameter Alternator pulley to sliw down V-belt speed in Inches per second so it does not break in 2,
You stand a much better chance of meeting all needs required the 1st time.
Also the 3G large case can put out 80-100 amps at a very. low rotor speed.
1,000 RPM's from what I read.
 
So what do You think Rick ??
Make any logical sense or just Hogwash.
We are both Bench Racing at its finest.

Pass that homemade liquor you Bob drink together.

So far I haven't picked up any parts.
You have not bought anything either.

I understand Hogwash better than logical sense, so no problem! :cool:

Here Brian, have some homemade Cherry Bounce ........How do you like it?
Here is where I do my Cherry Bounce research.



Ok, being serious now. I was doing my homework this morning trying to
decide if the 3G will fit. I looked for couple hours and finally just loaded my
tools and went to the salvage yard to get one. There's nothing better than
the real thing to see if it will work. Got it all off except for one 8mm bolt
I didn't have the tools for. I made a remark at the counter as I was leaving
....."You guys should sell tools" and one thing led to another until I was
looking thru a box to see if they had something that would work. Damn if
they didn't have an 8mm combination end wrench.

So did I get the right one, are the pics below of a Ford 3G alternator ???

Looks like I could hang the alternator backwards, otherwise the pulley might
be too far to the front. It would be close thou.



I found this pulley in clearance for $1.00, fits a 3G. The grooves are wider
at 1/2", my pulleys are 11/32" wide. Will the 11/32" belt work OK is this pulley???

Its the same 3G alternator I bought used today.
What's your plan Rick ?
Going to use as is ?
3G has never been used on a SBC.
Just Fords.
 
If you hang the alternator backwards like a Ferrari V12 it will charge but coo ling fans won't pull air through correct. Spinning backwards of normal rotation
 
Interesting enough Rick, the CS144 I picked up today is a perfect dimensional bolt in replacing a 10si.
Just slightly larger housing. May fit perfect in T-bucket.
 
I am going to take my Ford 3G Alternator and hang it on my 87 Corvette today Rick.
Take some carefull measurements.
I have a Verticle Bridgeport Mill. Machine off extra.
Mopar Bob can TIG Weld anything I need.
I like science experments & new challanges.
I can road test real world here for a week.
Report back.
Use my clamp on Amp Meter.
Oscilloscipe test. Graph out an Alternator Perforfance curve.

See how it stacks against a Delco CS144.
Use a cabon pile and load down to 100%.
Work 3G super hard.

The Iconic front magazine cover shoot & book by SmokeyvYunick Power Secre
 
Smokey is leaning against one of his NASCAR SBC He built.
Looks like 100% Chevrolet.
But its not.
Carefull eyes like mine, Smokey is using a Ford 2G Alternator 460 Ci style.

I bet fewer than 10 people have spotted that. in past 25 years.

If you think the CS 144 will do the job, then that would be easiest way since belt
alignment is not a problem. But I thought you were favoring the Ford 3G, so I
went a pulled one from the salvage yard to see how well it would fit. There was
no use in having you build one and then find out it wouldn't fit.

By hanging it backwards I did NOT mean how you took it. I only meant to use the
pivot side for the adjustment rod and use what would have been the adjustment
side for the pivot point. Always keeping rotor rotation in the same direction.
Check out the first picture above where I point out the Pivot Point, that's
what was used for adjustment originally.

Let's use the CS144 if you think it do the job. Even thou it might be bigger
in diameter than the 10SI, it also will hang down further because pivot point is further
from the rotor centerline. This give it more room to swing for adjustment.

I previously said the ratio was 2.2, well I mistakenly measure the water pump pulley.
When I compare the alternator pulley to the crankshaft pulley the ratio is really 2.65,
so that's better idle speed output.

I would also like to use two belts, that way I wont have to adjust the belt as tight. I
read somewhere yesterday that a single belt will slip some once you reach 100 amps.
The water pump pulley and crankshaft pulley I have are already for setup for 2 belts.
I only have roughly 120° of contact with the pulley.

So what do you think, will the CS144 do the job ???

 
I am ready to take some photographs Rick.
Picture of 3G Ford, CS144 Late style, 10Si.
Also have an early CS144 here. Photograph too.

I am thinking placing a small Folgers cofee can in the T-bucket in place of usual alternator will help figuring out how much room is available or not.

I had to work on the wife's Honda CRV '99.
Installed all new exhaust Cat back.
Quiet. Momma is happy & loves me again.

Pictures coming this evening.
Curious how good 3G is .
Early C4 Corvette guys have constant issues with the Delco CS130.
C5 Corvette guys are plagued by Valeo 100amp alternators.
Maybe suitable replacement for both Vette eras.
 

Big thumbs up for all your help Brian, I know you could be having a
lot more fun working on your Vette !

Be a while before I can complete my Vette as I want. I have always left it together & running turn key.
410 will destroy the stock dana 36 rear.
4-link rear coil over shocks, panhard bar, 1957-58 Pontiac 9,300 next on that car.
Then drop in 410.
 
6.600" Measured on Delco 10si endframe mounting points. Mean housing diameter about 5 " inches.

7.00" Measured on Delco CS144 LATE & Early style.. Mean housing diameter of 6" inches.
Late square style prefered. High amp unit as Dorian has on TT.

7.00" Measured on Ford 3G. Pivot stand depth 3".
Deco 10si & CS144 2" inches.
Modification required.
Mean diameter about 6" inches.
Experimental on SBC application.
Ultra high amp low speed charging output possible of 100 amps

Ford & GM alternator drive pulleys can interchange. Shaft diameter of 25/64" or 27/64" inch from my memory.

Decisions Rick........ :mrgreen:
 

CS144 Late Style
Double V-Belt Pulley
3 Wire Electrical Connection

What do you estimate the cost to be?

 
How come 3 - wire ??
Want PLIS layout ?
1-wire Hookup super easy for you.
Dorian ran double V pulley too.
Bought shiny chrome
 
Resistor adapter harness required for non OE Apps.
1-Wire no. Charge wire connect. Good to go.
