I know METAL MAN is running these with his Whipple setup (still runs the whipple auxilaries too) I believe he is still tunning some bugs out. Brand new, I know the Multech II injectors are really expensive. ...like 450 for new 8.1Ls i think

i heard the 8.1s were 30# at our pressure...if they're that much i might just stay with stockers until the big motor and then get some billet fuel rails and build a damn fuel system since i'm gonna have to spend a fortune on a system anyways it seems.

Guess who has a set? Not sure if I'm going to use them or not.

The marine 8.1 liter injectors flow around 43 lbs @ 4 bar fuel pressure which is roughly 58-59psi.
