Sourcing Hobbs switch
 

I've been trying to find an adjustable Hobbs switch (boost activated). They are harder to find than I though. Most of them are out of stock. I'd like it to be around 15-20 psi range. I'm sure there are more out there, just can't seem to locate it.

I use a nason brand part#cj-2a3-85g/wl. The range is 20 to 120 psi. Very clean on and off function.

Ive got piles on the shelf at work. They are used for oil pressure switch on many thermo king units. I used them for water injection before work great.

My problem is finding them that are normally open, closing around 20 psi.

Crackerman.. help Bret out?

I think I got mine off ebay. I will double check and post the part number when I get to the shop.

When do you need one by? I have a few.

Ill get a brand name off mine tmrw when i get home.. Mines 0-150 psi iirc

Of course mine could be some CHINA junk I guess we will find out tomorrow when I get the P/N

Thanks guys. I checked out the one Ponci posted. It doesn't have much info, but looks like what I need. I don't have to get it super quick. cracker, are yours adjustable?

Yes they are. He can ship to you or we can carry to finals... Or Sunday afternoon I will be driving to Houston we can meet up on45 somewhere..

Ok, whatever is easiest. I got drugs on the way for my truck, wanna make sure it doesn't kick in too soon.

Yeah, riv can carry one down. You will need to hook it up to air to set to the psi you need. It is set pretty low now. Like 2 psi. But goes way higher.

That's awesome! Brandon, sending you my number , now.

im going to be putting mine on the laughing gas after the finals and i was also looking at the hobbs switch my question is what pressure are yall setting the switch at and how much would you sell me one for crackerman?

I'm thinking around 20 psi, but I'll just have to play with it to see.

would you put the switch in the intake horn next to the nitrous line?

haven't decided yet. I'm going to tube it in, and mount on the firewall somewhere. I've heard some don't like the vibration & heat. I'm putting nitrous jet in the intake horn though.

do you think if i just tee'd into my boost gauge line it would work that way i dont have to take up another spot on the intake horn and what your talking about doing is what i was planning on too

That should work fine..
