On the stock ski this weekend we are going to put a Riva Intake Grate and Riva pump wedge, the 15:20 prop, fill the holes in the ride plate and all free mods and forgot to mention we are running 42 lb. injectors Shooting for 77-78 mph

No, but on the Stage 3 boat we are running a Rotax Racing fuel pressure regulator with 48 lb injectors, fuel pressure regulator is set at 44 psi and its tacking out at 59 psi - this was tested by Mark at Racetech- and we are gonna get a Dino Tune ARF meter soon.

Mine should have some numbers next weekend.
4" front intake
Riva Pro-series Intercooler
14-19 3 blade
plate holes filled
Riva Rear exhaust---stock waterbox
I need a 15/19 3 blade as well. I bought the 14/19 when I was going to run the stock ic.
Between this addiction and my Mustang I think my bank account is going into cardiac arrest----looks like the stock market lately----UNSTABLE .
