Is there any tools out there to like GGDT for combustions? I live in Madison WI and the only time i get for testing is leading up to the 4th of July or when I go camping. I would like to build a pneumatic to equal the power of my combustion and make portable and use a bike pump. I don't want to have to reinvent the wheel so any help would be much appreciated. My combustion has a 2"x48" barrel and a 4"x14" it has a 1.11:1 ratio.

Contact BoilingleadBath for the tool like the GGDT. Thats gonna be a mini pneumatic to equal the combustion. Psssst -- pneumatics are stronger then combustion.

I just got EVBEC v1.5 and I'm going to try and figure it out.

The problem with a tool to calculate power for combustions is that there are hundreds of possible fuels to take into account. And apart from metered propane or something else metered it's very hard to get a stoichiometric balance in order to achieve peak performance so the took has no way of calculating user error in spraying and praying.
