8bv50 is a straight 45 helix, that might be better for you to tune with as its easier to get a straight shift curve before you switch to a multi angle helix. Also if the helixs are all differnt brands your not really gonna be able to compare angles as they all shift differntly as to the radius in which the helix is cut, it makes them act more or less aggressive.
try that set up i gave you... borrow a set of 8bu-00, they are not the same shift as 8ca, check the mph and see what you get.
I have always used maxx perf helix or dalton. You will find all differnt results if the helix are all differnt brands or are "coded" helix's like hauck and bender , that you go off the info on the internet, as its usually wrong if they were not actually measured on a cmm to see what they are actually cut at.
