Dyno day....
 
Made more pulls than I could keep track of..

At 4 pounds of boost we were at 603 hp and and 605 tq (that run ran up to 5700 rpm)

At 6 lbs we were at 625 hp and and 650 tq at 5500

HP never stopped climbing/ nosed over either.

Im looking at getting a bigger top pulley and knocking it down to about 3 pounds to help the drive be a bit happier..

My little boat should move pretty good with this little 454

Many thanks to Lightning Jet and adk61 (Alan K) !!!!

Nice!!
You should probably give the hull bottom a good cleaning. Pretty sure everyone around you is gonna see more of it this summer when you’re flying.

Took care of that last summer, along with raising the x-dim a couple inches
