Depending on what Lynn suggestes, but your experience with the spintech or your latest version is appreciated.  Do you have any tests with a decibel meter?  My exhaust noise is just too loud, fine for me but passengers do not exactly que up for another ride. So design starts all over again, but I do have another engine to play with to keep mine in the air while I experiment.    Here again Todd you have the electric water pump --- thoughts? Neil.
