Data logs show around 2 psi at 4900rpm .. that`s crazy! with the same pulleys last set up was 4-5psi
Either the 6`s make the boat more efficient or the new heads and intake flow very well, probably a combination of both .
Tune had a zeroed out cell in the fuel table so that`s my back fire and the tab lines were reversed . Can`t wait to get it out again !

Dan,

Time for smaller pulleys up top.

Thanks. Brad.

Are you putting scoops on the hatch, that little inflatable looks like fun

I spent some good $$ making those intakes shorter so that hatch better fit . No scoops.

4-5 psi to 2 psi @ 4900 is a nice milestone.

Real data feedback in the right direction, always good to see.

Heads likely flowing better...and less throttle required @4900 with the drive/prop changes.

What paint did you use on the blowers?

Gorgeous!

Attention to detail is off the hook!

Well done sir!
