Holley boost control-co2 or compressor air?

Yes, the many drinks that I had before I had that awesome post. For whatever reason I saw the graph he posted and didn't register the dome sensor as the pressure sensor. I'm guessing I connected that with duty cycle. At this point, your guess is as good as mine.

I was a bit confused.

Dual solenoid wastes less pressure source and is more accurate. That's why AMS and Leach use this method as well. The Holley can be used with a Single Noid also.

There is no advantage to CO2 or compressed air. When using compressed air, you can either regulate to a fixed constant 60-80 psi like CO2 or you can stick a 0-150 pressure transducer in the tank and reference it back to the Holley. On my street car I run compressed air as filling CO2 bottles is a PITA. On the 7 sec car we have a medium CO2 bottle that we fill in the trailer with a 10 lb (mother) nitrous bottle (with nitrous in it). It's just being used for pressure.
As for running off the compressor cover, you need to make boost to make pressure if you do it this way, where as the external pressure source is available from idle. This allows for much better control and faster spool.

Im running all holley boost control components. I spent $100 per noid and $117 pressure sensor. I see your avatar is Holley. I assumed its the same as the $30 MAC valves but got caught up in having the Holley sticker apparently. lol Which is what I'm assuming you are saying they are the same. Esp when it showed up. The instructions for the dominator address using their noid and not the other MAC valves out there, and say its configured for the Holley. Is there anything you have to do to configure the $30 ebay MAC any different than the Holley sticker one or you saying its the exact same? Not that I can think of needing another pressure senor for my car but for future reference. Where do you get the $20 one and anything you need to do to configure it as well?

Yeah, just noticed that the LS1Tech police stripped the text out of my signature. I am not a Holley Employee. I am an independent remote tuner/educator for the Holley EFI. Yes, I am talking about buying the Mac valves and eBay Transducer. The noids are identical and the transducers usually are also. If not, they are easily rescaled to the correct voltage range in the software.

Thats right! You are the one that offers remoting in and walk/throughs over the phone for a few hours for a couple hundred bucks. Everyone that has gone through your class has said it is worth its wait in gold and you are the man when it comes to Holley info. What is your fb page again? I wanted to get more info. I can pm you for more info to not dirty the thread.
Not trying to thread jack, just saying from everyone else, this is the guy to listen too. lol

Word of caution with the eBay transducers. The connection between the pig tail and the sensor can get loose and cause ALL KINDS of fucked things to happen. I chased a intermittent boost issue for a month before we figured out what it was. Just make sure the connection is nice and tight.
