Spinning a Berkley 12JG at 6100 RPM with an A impeller roughly how fast would it be? 19 foot boat very light and very shallow V bottom.

Could be in the upper eighties, low nineties. I could tell you for sure in a tunnel, but not a v-jet.

TO be spinning 6100RPM's with an 'A' impeller you must have bo-koo HP or a pump that needs to be re-worked.
We run around 5800 RPMs with a 'B' impeller and run a true 97mph. This is in a CP wullwing

It is my sons boat. We figured somewhere around 90 mph. The motor is one of my old race engines. Tunnel Ram, 477 BBC Manley rods, Veniola pistons, roller cam, Crane Gold rockers, stud girdle, Some old Pro Stock GM alum heads.

Speed consists of lots of stuff.....
Just to show ya' what I mean - my TX 19 (a similar hull as wrightnow's CP gull wing) ran mid eighties at 6500 RPM with a 'B' impeller. Maybe my pump is looser, ride plate adjustment off, different intake / pick-up, nozzle size, droop snoot / wedge, there are so many influences I get confused.
It could be the water is stickier here or maybe my Texas size goat smellin' butt is slowin' me down, or I carry a bigger cooler or more gas. Is a 96 quart cooler too big?
Hitting the right combination is the key to mph. I can't predict it nor have I been able to find it, but I really enjoy lookin' for it - and I have a little extra time to look because I don't have to refill my cooler as often as most folks!

Already got 3 sons they keep me pretty busy! I was talking to Phil Bergeron and when I told him that I bought my son this Hornet he told me he thought they were the best V bottom hull he ever seen. Even though oldrigger said the mold plug was made from beer cans! Maybe thats it??? The Silver Bullet? Actually the boats name is the Green Hornet. Jay at East Valley Performance Marine blueprinted the pump. The hull was also blueprinted. http://www.highperformancecars.com/highperformanceboating/hornet.jpg

What wrong with beer cans? Beer cans and I are very close...literally. http://www.goldenplasma.f2s.com/forum/smilies/happy33.gif
That is one sweet ride. Are you sure you don't need another son? I promise not to eat too much. You'll hardly notice little HH as well. Can you say, "Granpa Ray"?

Great looking boat
anytime you can push a shallow-v over 80mph your doing great. Its got to be a wild ride.

Thanks for the compliments guys. When the kid lets the old man borrow the boat I got to say it is really a bigger rush than doing 150 in my Chevelle. Funny how it seems so much faster in a boat. FastDave I guess ***boat didn't see the humor in that pict I cleaned up for you LOL! Glad you took it with the intent that I had. Maybe I need to do a pict of ***boat next?

What a nice ride. I'm sure Marty Hatchel has a big smile on his face when he looks down ( or up ) and see your sons boat. Very nice.
By the way, Marty told me that he personally finished off those beers before he used the cans to tool up that new dash.
I wish I could remember what bottom he splashed, but I can't. Couldn't be to hard to figure out though, hard part is trying to figure out where the bottom originated
