I have a 127" Ultima (2004 vintage engine) in a 98 Road King. Would I need to drop the compression from the 10 1/2? Would there be a kit for ths application? What kind of power would I expect on 93 fuel?
I would like to see 9.75.1 but you can still run a procharger at 10.5 but just only 6/8 psi boost.
At 10.5 and procharger right now you could make 185hp easy...
