Air shift? Wastegate? Both?

 

[64nailhead]

Just wastegate for now. After this I'm all out of outputs.

I am not sure what you are cooking up there?

Is that better/more consistent?

Is that better/more consistent?

More consistent than a single 3 port or 4 port Mac valve. A 3 port is limited to approximately double the spring pressure, a 4 port will do 4-8 times of the spring pressure easily but with less resolution. This allows for very high resolution (meaning adjustable boost levels with the tune).

A 4 port works quite well most of the time if the hot side is well designed (mine isn’t - lol) .

Mostly though, I can’t build boost launching because of my poorly designed hot side, but CO2 based dome control will eliminate that problem.

And this is pretty cheap - about $220-240 between the two Mac valves, dome sensor and CO2 tank and regulator.

How long does a tank last?

 

[64nailhead]

A 5lb tank will make about 400 1/4 mile passes. Yes - 400. And CO2 is cheap.
