figuring 30hp for the drive and 30 for the accessories, that leaves approx 508 PSHP so I figure around 15% slip with 1.50 gears and a 26 four blade if ya can pull it to 5400 will net ya 78mph dependant on load.

Firewalker...first of all wow excellent build up. From everything I have read/know about the p-22's you should be up around 80 with no problem. Where are you located in canada. You guys up north love your pachangas....selling mine and that is where most of the hits are coming from. From others who have gone close to your setup with a 509 at about 525 hp they were getting 75 at 4900 rpm's and the peak rpm's for their motor was 5700 rpms...so that might give you a closer idea....I say 82mph. About a 3200lb boat with that setup and bravo and your hp, should be close to that...keep us posted.

Firewalker

Good bet, packer, I am gonna say 82 mph. It ran 72 with the crankcase FULL of oil.

Yup we love them, you can get 25k for a good clean one. The key up here is WINDSHEILD.... short summers. And there is a region up here called muskoka, and on the 3 lakes they are somewhat trendy........ I wanna have the FASTEST one.

I think you should be right up there as being the fastest. Go with a 4-blade too, they seem to be the best on these hulls with bigger hp. If you know someone looking for a VERY clean p22 let me know. Clean boat looking for big hp. I hear ya about the windsheild....lot of people think the same way up by me in the 1000 islands. I will have to see what the new boat is going to be like without one

Firewalker

I have a few with out, it is nice to have one with.

I have a 26 Bravo 4 blade to start, I think I am going to need a 28, and then I will order a labbed 28

Send me some pictures of your boat, I know of a guy looking

twible @ roycap.com

Well, I'd say your boat weighs about the same as mine.
I swapped from a 310HP/7.4MPI to a 415HP/502magMPI and gained 8-9mph to a top speed of 75-76GPS.
I'm guessing you will crack 80 with no problem and may see 82-83 if you can keep her running true.
An extra 230 ponies is quite a jump!
Good Luck!

Hey Firewalker, would you mind sharing the specs on that new cam?

Airpacker

Rob, I have a 28 bravo you can try. When we going water testing, the lakes aren't hard yet

PatM, its a standard hp500efi cam.

Firewalker

I hope to be boating next week with it to shake it down. The Cam is the HP 500 carb cam ( might be EFI ). The guys apparently were pretty shocked at how it the intake and the roller rockers woke the motor up.
Interestingly, the OEM rocker studs were LOOSE.

RT..... and low 80's would be a dream. I sure hope so.

Thanks for letting us know how it turned out. It's interesting and informative to follow these things to their conclusion.
