so what you're saying is to go to a bigger turbo with less back pressure from the exhaust housing/turbine, and then use a 'wilder' cam with more overlap and duration than is normally considered. that will up the volumetric efficiency of the engine considerably and allow the turbo to boost up nice and early?

i've been to your fine country to a gatebil meet at rudskogen, and couldn't believe the size of turbo's that you guys run, and how quickly they spin up

by the way, why have you done away with the coil on plug system from your ybp engine and replaced with a coil pack type? better reliability due to heat?
