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.

Hi George,
 
You've chosen well.  I've used those exact = two=20 injectors types in the RV-3.  The current config is 4- 38 lb/hr = injectors,=20 which idle better, and still have plenty of fuel capacity for full=20 power.  The 50 lb/hr injectors worked just fine as well, though = they didn't=20 idle as well.  I'll probably use two of the 50 lb/hr injectors = in the=20 single rotor, since I have them available, and I won't be trying to get = a low=20 idle.  
 
As for the price difference, I just assumed = that=20 anything sold through a carmakers parts dept will be way more = expensive=20 than it should be.  I'm sure the MSD injectors are used in some = cars as=20 well, and if you could figure out which ones they are, I'd bet their = parts=20 dept has a much higher price on=20 these.  
 
Also note that the electrical connectors are = readily=20 available, and cheap.  That was one of my other gripes about using = the=20 Mazda injectors.  In some cases, it's impossible to get a new=20 connector, so you're dealing with junkyard=20 parts.
