Yep, just haven't had a chance to update the web site. With the Raylar kit and stock exhaust (turbulators removed) made 530 at the flywheel with full wet exhaust. Switching to the Dana's it made 553.7. The boat went from 63 stock to 73 with the Raylar kit and exhaust.

Wow, that's really good. That means the Dana's made about 32 hp over the stock manifolds (if not turbulator modded). With the Dana's, I believe that puts the Raylar package a little over the Merc 525 (it's around 540?) Very good!
The speed gain is what I would have predicted for that hp increase on a stepped v single bravo. It proves you're getting the performance from those new horses
Thanks for giving us real facts and numbers

The raylar kit with cam, roller rockers, intake, and heads? Upgraded fuel pressure via PCM? W/O the cam can one expect 540hp?
