Rusty,
I have identified the local supplier = and MSD=20 are indeed cost effective.
I have selected a 38lb (2018) = primary and a 50=20 lb ( 2013) secondary for the single.
It may be wishful thinking but I don't = want to run=20 lean at 7,500 rpm. The 2x 400 cc ( 38lb) runs out of puff at 121hp and = I'm=20 hoping for a tad more than that with the PP and RX8 rotor. In the end it = may=20 only be 125hp but the combination will reach 140hp within the 80 % duty = cycle so=20 I figure I'm safe from running lean.
Question=20 is how come these are cheaper than the mazda and = other=20 known brand injectors - I expected them to cost = more.
