HGDT questions

Harness the power of precision mixtures of pressurized flammable vapor. Safety first! These are advanced potato guns - not for the beginner.

#1- what is ignition number?

#2- I heard that if you make a volumetric meter, it's a major PITA to do the calcs, but can't you use the tool on hgdt to do them for you?

1) Number of spark gaps.
2) Yes, you can, but HGDT is relatively new, so it was a PITA before then.
Does that thing kinda look like a big cat to you?

1) as above
2) yes, but you can use a manometric meter for hybrids (not sure about combustions) where you put in a certain PSI of air and fuel for vertain mixes, it gets rid of the pipe on the side and the calculations.

(i have a word document written by spudfarm on manometric meters, PM me if you want it emailed)
