Hmmm,
That says that the 550 and 1600 injectors are good for over 650 HP!!

The "V" in Velocity must stand for Vertical take off! :>)

Chris,

    There was a lot of traffic on this subject in 2003.  IIRC Ed Anderson
was/is using MSD injectors (2012?).  Dunno if they will fit the Mistral
manifold, though.

   Some interesting info here:
http://www.robietherobot.com/Storm/fuelinjectorguide.htm

and here:

HTH,
Dale R.
