Enderle K valve?

Does anyone know how many GPM a Enderle K valve with a nitro spool can flow with -8 lines in, and out before it becomes restrictive?

 

I think there is a 15 or 20 pound pressure loss across the barrel valve. So there is a little restriction even at 15 to 17 gpm.

Not sure why you would want to run a -8 line anyway. Always supply the barrel valve with more than enough fuel. If you are running the right pump you will not need to worry about pressure between -8 + -10. Just my way. Don

 

Fluid flow is a stange thing.

What is an acceptable PSI drop?
As input pressure goes up flow will increase but not propotionally.
eventually the restriction will act as a aircon valve and the fuel will act like a refrigerant (spelling) and freeze

 

This is for a N/FC, the enderle 1270 pump has a fairly small outlet, thus the -8 line into the barrel valve. We got a 21 gpm max rule on the pump.

 

Anyone on here have any experience with a Pete Jackson B/V on a Nostalgia Nitro car?? Where can I get one of these?? Thanks

There's one on fleabay right now

 

Nitro barrel valve

But I think Spud Miller has a better mouse trap. They are all a bit pricey, but you get what you pay for- fuel flow that doesn't starve the engine and kill stuff.

 

I was looking on Spuds site and only see Enderle?

 

we have always ran enderle K style on our cars kenneth. used both 8 and 10 line.

 

Yea us to. 5.92 @ 245 with a K valve in NFC. Thats with the max flow of the rules and no restrictions. Call Jim at Enderly. He flows systems every day and could tell you the answer your after.

AFC357. In my opinion I would stay away from the PJ valve for the nost class. It was designed for big big pumps for the big show. I beleve all you need because of pump,blower,mag and gear restrictions is a K valve.

 

Ive been "told" the Jackson and Settles are "better" for the adjustability of the idle circuit??? New to Nitro and I only want to buy the right stuff ONCE! Any experience or opinions...make that "experienced opinions" appreciated

 

This is true. It is not for the inexperianced. You really have to know what your doing or you will never get it leaked right. I have seen quite a few guys struggle for hours. Finaly Spike Gorr walks over and streightens them out. If you buy that the Jackson or settles do your home work. Pleuger uses the K valve and has the fastest NFC. Its all ligit to

 

I do know that Romines car has a PJ barrel valve, while Pluegers cars are the most legit N/FC's out there they are in a league of their own performance wise(which is probably why the NHRA hasn't tried to slow down N/FC's yet).

 

Call Spud. I just got a note from him last week about his new one. It is made by Spud and he had not put it on the website yet. Not cehap, but none of then in this quality are.

 

I'll call Spud today, I don't care what it cost as long as it is the RIGHT piece!

 

B.v.

If you want a B.V. with a trim then go with the GORR B.V. He tunes many good running NFC's and can help you with the tune up.

K valve

Kyle,

What is the highest pump capacity you know of that an Enderle K valve with a nitro spool will handle?

I have a 28 gpm setup we're going to here, and I know I'm going to dump a good bit of that back to the tank, even @ WOT. But I'm wondering if I really need to be looking at a different BV, if the K valve I have will work with the right spool in it.

I think some of you are making more out of this than need be. The K valve or any of the improved clones isn't the cork for most folks since they are a straight through design at WOT. It's the fittings and hoses you need to look at.

The ID of the K housing spool entry is .500.
The width of the K spool is .500 -.560 depending on the spool used.

IF you had 16 nozzles measuring .100 ea you have a total nozzle area that equals a .400 Diam. Anyone run that much nozzle?
The ID of a -10 race fitting is nominally .477 diameter. Your hose ends may or may not be smaller than that.

I never had a need to find the top end of one of these since I don't do big show stuff.
FWIW, mathematically speaking, a .477 hole @ 100lbs should flow alky in the 60 gpm range.

The idle features of the fancier BVs should be a good thing for nitro engines leaving from a high idle with a glide.
