Even with the 2-step, the engine should be able to build boost and even if it can't, it would be really loaded with unburned fuel. I wouldn't want that to go "pop".

No ,they're draw through. The carb is just in a funny place !
The two step is okay with the pedal switch but here's the problem:
As the boost climbs, so does the stall speed. It will eventually level off with a 2 step, but with every snap ,crackle and pop, it will still climb.
You've got to be ready for a quick tree, so, seeing you'll leave first 95 % of the time anyway, as soon as you see 4 stage bulbs, you need to go to the floor as quick as you can.
Better chance you'll be maxed out with boost...If not...you had a bad day!

Mark,
You are exactly right. I had a bad day racing Billy at Indy a few years ago with the Capri.

I don't like the button on the brake pedal deal. With a pressure switch once pressure is released the 2 step turns off. Your foot is still on the pedal. With the button on the pedal you'll have to get your foot off of the pedal and the button to disengage the 2 step.
