Re: Going to the DYNO today

- Set the timing map conservatively at 15
- Add boost until I'm satisfied
- Maybe try adding some timing back in

What I don't know is how much boost do you add before you give up adding boost? Do you watch intake air temp?

As long as there's no detonation, why not more? I'm limited by the fuel system at around 1200hp anyway, so I'm hoping to hit 1000 and call it good.

Could go on the dyno as early as this week, just need to weld one more O2 bung in for the computer.
That's gorgeous! What is it going into? I have very little experience with blow through carb. But I believe you are on the right track. Air fuel ration plays a lot into it too. Add boost until it gets too lean. I have a big idea to add a turbo or turbos to my 354 after I build the engine.
