68 Classic valve question .... Regulator bodies ?

[Motorhead]

I just picked up a like new classic 68 valve assm with Ser # in the 66,000 range.
Pretty sure it is a newer valve with such a high #, along with side of valve saying "CLASSIC"


So here is my question:

With so many regulator upgrades being done threw the years that replaced the standand ONE HOLE regulator body with 6 -8 or more holes, WHY would a newer matched ser # valve be built only having a ONE hole regulator body ?

Pro & Cons of these multi hole regulator bodies compared to one hole units ?

Enlighten me Please

Scott


PS, I am aware that shoot down is less with better recovery from increased regulator flow, but if more flow is generally a good thing, why would you go backwards in design ?

[cyclic]

The early designs did not have the holes lined up, so a 6/8 hole mod allowed for the gas to flow better. The newer style has the holes actually indexed in line with each other. The gas flows straight across. With a newer valve you gain a small amount of volume but little to no flow when you add the extra holes. Not enough to make a difference.

Hope that helps.

Ok, thats one response ... speak up guys ?

Over at MCB, someone has stated AGD Never has made regulators with more than a single hole

** If thats true as well, then is one to conclude ALL the 6-8 hole high flow regulators along with the ANS versions are ALL after market attempts at a design that does not work any better than a single hole O.E.M reg

Thanks,

Yeah, I don't think AGD has ever made valves with more than one hole. They didn't always match up at first so other companies made new valves or drilled AGD ones. AGD fixed the problem by threading the valve and reg so the holes always lined up, so there was never a need for them to drill more holes.

No one responded cause cyclic had it down. And Pixel was also right. I suppose a pro to the multi hole is you lose a few grams.

And gain a little volume, like Motorhead said. Could this be the new SP Magic Box? Time to start dremeling the inside of some valves!

...Don't really do that...

Dang it, by the time i got to the second half of your post i had already done it, i hope you know you owe me a new classic valve.

Anyway, i don't see an increase in volume as a pro, as it will make the mag even less efficient. Wasn't it the mag with less volume that ran at 450 psi that got better efficiency?

[Motorhead]

Thanks Guys !!

Being new too Mags, there seems to be a LOT of Snake oil / smoke & mirrors done by quite a few of the after market parts vendors now long gone from the Mag PB scene

AGD has made 8 hole mod for PMI perfect charger and i think they did it for smart parts too.

Yeah, I'm pretty sure that (at least as far as 'mag valves go) higher pressure means better efficiency; has the advantage of fitting in smaller spaces, too. As I recall, the Magic Box hurt efficiency a bit, and AGD did some tests on valves with smaller chambers and got some decent results. The "low pressure" craze pretty much took the wind out of the sails of that idea, though.

It's not how good you make it - it's how good you sell it.

Exactly, there can be a marker that is just spiced up spyder and it'll sell better than a quality marker like the mag. People can be very stupid in that respect, and that's not good for me because i've never been good at marketing because i always feel like an asshat when i do it.

Oh, and divil, AGD never had an 8 hole mod, it was either something customers did or it was an aftermarket part.

I stand corrected, AGD never sold them to the public, however they were more than willing to do it as a commission for another company, even though it voided the warranty.
