New HP 770hp 340 Vyper
Just got done adding new power, now the testing begins.

588ci (4.560 x 4.500) Tall Deck Bowtie block 770hp naturally aspirated.
High elevation 4500ft, 5800 rmp 88GPS with 28’s. need to get a hold of some 30’s.

Here is a pic that Bryan wanted me to post...
Flame arrestors are custom fab
Also note that the boat was an absolute handful at 80 with props turning in.
Turning them out was a night and day difference. He has permanently switched his controls to spin them in the much safer out direction.

Pretty sure I can get in the 90’s with some 30’s props. Got a set of 33 for low elevation will have to give them a try from fun.
And yes the Arrestors and awesome. maybe he'll build you some
