Help with speed!
after all my mods i can only manage 70.9 @ 7180. my efi settings are set at 6-6-1.5-7. i had my settings at 5-5-1-7 and it would bog when i hit the throttle. any help would greatly be appreciated. i'm looking to hit around the 74-75 mark maybe 76

i looked at the pump and it's fine. maybe it's the heat. it was like 90 degrees yesterday.

Is this the ski you were racing Pistonwash with? Did you lose the speed since then? If so, what has been done to the ski since then?

yes it is the ski that raced pistonwash. my old setup i ran 69.9 @ 7080 and since then i installed VF3's, speed plate with angle at 5 degrees and i have one of my head hoses dumping overboard.

Maybe the VF3's didn't seal up well when installed. This seems to be a problem for some people. For a reference I ran 73.1 mph with these mods at 7180ish rpms in the heat.
D-Plate (opened up .110)

they're sealed up. they went in smooth and painless.

No head mill? Your able to turn that 14/20 fine i guess too?
