A local buddy is doing a Hansened Raptor right now. Plenum volume is really needed on a single or the fluctuations sap all the boost. Always pumping, drawing 1/4 of the time, ish.
I did a bottom end for Aussies that run 100cc and an AMR300 at over 120mph in a bike, air cooled 2v hemi chamber.
A wide band and EGT, with a nice Tilly seems the best for making it live while exploring the limits.
Dipper oiling, ugh. Generac may be a better SB base?
GL on it, regardless.
