I am thinking that I would need 2 of these?

 

Yes, you would need a total of two boost controllers, one for each gate. Unless you decided just to leave the second gate closed full time as I still have a tough time imagining you over spinning that primary.

What do you think of this one?

Its more pretty,, LOL

 

It is a really overpriced air regulator. My problem with those the same as with the needle valves, is that they let air through all the time right up to a set amount of pressure, and then that is as high as they will let pass. Similar to a regulator on an air compressor. In a boost control function this just means the waste gate starts to open well before the desired setting. This is kind of like having a boost leak, and just makes everything slower to respond. I prefer the ball and spring style, where it is closed until pressure is reached.

 

I have one on those on the shelf. Never used it yet. I would run a decent size diameter hose if you put it in cab. There are pneumatic switches out there as well. You can program them to open at different pressures. I'll find the link for it, they are priced right. Kinda like PCL stuff, but use pressure. I want to give them a shot one day. I'll try and find the link. I was thinking about trying find a cheap skate gate programer system. Industry used to use pneumatic stuff all over the place, so its out there and is priced right. If you do it right, you could use it for a data acquision system. For example you could program in your nos, water/meth and gate all onto the same system. The trick is to for stuff thats 12v, most is 120v AC or 24v dc
