The valve that it just looked at(on a Ford) was a 2"valve in a 3" intake pipe!

dus any one know of a manifacure or a link that could help me find abigger valve for the cummins?

It looks like i will be installing a fue of them on the dodge oil field truck!(natural gas area)
I really dont want to us the one i just seen on the ford and add a restrction (power lose)to there trucks


Any help and or sugestions would be gratle apreceated!

 

You might consider adding a carbon dioxide fire extinguisher instead. Mount it in the truck and run an extension hose thru the firewall and connect it to the radiator support with the end pointing into the air cleaner inlet opening. It could also be good in shutting down a run away engine if the turbo seal failed.

 

I've heard of people using the CO2 fire extinguishers before to stop run-away. I could see using one in an extreme emergency (like uncontrolled run-away), but it would be last resort for me. Every CO2 extinguisher I've ever used has always had tons of other crap in it too. Just using 1/4 - 1/2 of one will coat everything nearby in layers of powder. That grainy powder can't be good for the engine.

 

The ones that sledpullers use are 6-inch by 6-inch spring-loaded guillotine contraptions...

 

That was not a straight CO2 extinguisher but a from memory a Class ABC that has dry chemical added. Those are actually a multipurpose extinguisher. A true CO2 extinguisher has only CO2 in it. It is the one that has the large outlet and when used usually get a coating of ice on the outlet.

 

CO2 leaves no residue, your thinking of ABC dry chem. which would destroy an engine in short order. If your CO2's are leaving behind a powdery residue I think its time to find another place to get them refilled.

I would try Scheid's and see if they have something or know another place that has something.

 

Ah, I guess I've always used the ABC general purpose kind then.

I have a straight CO2 tank that I use to fill tires and run air tools on the trail. You can get them really cheap from a beverage or fire ext place. The regulator ends up costing more than the tank, but that setup seems like it would work well to shutdown an engine AND provide air for tires and emergency air tool use.

 

Thanks guy for all the replys but the oil field that thay are working for want the michanic shut off air type an i have three of them here......man i just dont like then at all. Pic's in my gallery!

found the company that make them and sent them a e-mail reqestin info on a updated on with a bigger valve!

the company that sells this valve sells mostly oil and gas valves

 

The big sled puller places like Schieds or Piers or Haisley should be able to hook you up...

I was fondling one of those guillotine shut-offs at Indy this year that was for sale... I think it cost in the neighborhood of $60? I don't quite remember, but they do have them.

 

Did it have as, restrictive of a hole as, the one in my pic gallery?

do you remeber the maifacures name of the said fondling!

EDIT when you said the guillotine i fig you had seen my pic but it hasn't been aproved yet!

 

No, it wasn't a circle; it was a 6x6 aluminum square.

It can't be too hard to fabricate a valve that big, can it? Don't know where to start, but it can't be too hard...

 

Ya the only problem is that i'm.....alergice to much fabbing


Ya the pic's are up!!

 

Does anybody make plastic sewer-pipe valves that big? Could you find a 6-inch, plastic gate-type sewer valve at Home Depot or Ace?

You could bolt an aluminum plate onto a couple tool box drawer slides or other kind of channel, don't know how you could get a rectangle to seal though. I don't think it'd have to seal to good to stall the engine, but you don't want to be sucking dirt either.



Wait a second, how big is the inducer at the turbocharger? 2 inches?

Why don't you just install a spring-loaded brass gate valve onto the end of the turbocharger inducer? Don't know how you'd thread or weld one on, but it wouldn't have to be good for that much PSI and I don't think it would leak...

Can you put pipe threads onto a turbo-charger inducer?

 

the probem is that if and when thay ever deside that thay need to us this device the eng will probabley be over revving before thay hit the switch!

Then you have a piston trying to suck the valve apart and a turbo trying to push the valve on the ether side!

the guy with the ford said that he had to dubble clamp the hose to keep it from blowing off....showed me the dent in the hood!

 

You could make a "blast gate", exactly like used to control suction in wood-shop dust collection plumbing.

They can be made, or bought at any woodworking store, to fit any size tube, round or square.

A pretty sophisticated metal one will cost about ten bucks.

A blast-gate can be closed as much, or little, as desired.

We had a big well come in, once, and the natural gas in the air would cause the dozers and oil-trucks to run away with themselves.

The oil was blasting out of the ground by the tens of thousands of gallons.

They were trying to dam it up with dozers and were pumping it into tankers, straight from these dozer ponds.

It blew like this for days.

Any engine that got close would suck the natural gas in the breather and runaway.
