Let's Talk Boost Control

I have a two stage boost control haywired in that seems to work, but I want to refine it. I apply a fixed known regulated pressure to the dome when switched in, and bleed it out when switched off. It is just on or off now.

I'm just using air, and it hardly consumes any air just being on at a regulated source pressure or totally off. All it takes is enough air to fill the dome every time it commands full boost. The turbo actually winds up a little slow, so it isn't a big fast surge in boost. It takes about 1 second to go from 15 psi to 21 psi.

It looks like if I ramp it up and down by using PWM, I can get a longer smoother boost ramp but it also says 9and makes sense) it will use more gas.

So if I get a CO2 2.5 lb canister kit like this one:

Dedenbear CO2 Bottle Kits AB25K - Free Shipping on Orders Over $99 at Summit Racing

How long should a bottle last??

I'm thinking of doing an air shifter along with using the bottle for adding boost.

Thanks. Tom

Do you use a 2.5 lb?

What do you think of my idea of using a single bottle for shift and then step regulating down to maybe 10 psi or whatever it takes to add gate pressure??

I want add enough dome pressure to just get my boost to the highest boost psi I might want, and then use the Holley HP system to step into the full pressure. I'd like to try to just step it after the wheels come down. The turbo seems to take a second to move my MAP up from 15 to 21 PSI. I'm going to add a little air tank regulator pressure and change the pressure to 25 psi and see if it acts the same.

I think I can just mount the low pressure regulator next to me, and use it as a dial a boost.

yes... 2.5lb bottle...

we use a regulator on the bottle regulated down with this

may need too run a 2nd inline regulator for an air shifter. i cant remember what pressure they need to be ran at

Try these guy's for your regulator. They also sell the 2.5lb bottle but I couldn't find it. I saved a few dollars going to them.

Thanks! I'll get on this when my car is back from the chassis shop.

I didn't think about it when I looked up that regulator but if you go to their site they also make a dual regulator. That way if you needed to different pressures for your shifter and the other one for your boost control you would have it.

I'm making a bottle holder out of 4.5 inch ID 5 inch OD 6061-T6 aluminum tube.

I'll use dual regulators, a high side regulator for the shifter and a low side that feeds off the shifter pressure regulator to the boost controller.
