Interceptor...did you get that gps out of kilometers mode? seriously...what happened to you, I sure hope that hull didn't delaminate from all that speed.

OSO'rs we've seen some good ones from time to time, but this has to be the best one. He claimed he was running 90 with his KPlanes alll the way down

At least he is smart enough to make his rpm/prop/gear ratio add up to the speeds he is claiming. I would say with that motor and boat he would really turn a 30 Bravo somewhere around 4000 rpm. Maybe 4500 with his k-planes all the way up.

There is a guy on this board with a similar boat. Brad Perry has a 22' baja with a 540ci blower motor on it. The motor has been dynoed at 868hp and he hit 105mph. So this guy has a bigger boat thats probably heavier with a small block with a couple hundred horses less and runs faster. I dont think so.

90mph with the tabs down makes me laugh too.

Look here is the Performance Profile from Procharger,These are for Carbureted Applications ,But close enough ! Check out Mariah for a base Parallel ,That Slug would have to be making between 850 and 1000 horsepower.

Well I took my 232 Interceptor out this moring. I took it out on San Diego Bay around 5:30am it was Like Glass... The Procharger is Awesome, it has the most awesome sound when it is spooled up. There are some things that I need some advice on from any of you guy or gals that are experts about speed. First of all my idle is 600rpm and the boat idles at about 9mph, which makes it tricky as hell to dock or put on the trailer, second I took the boat up to 90mph and I started to get massive chine walk and the boat felt very, very unstable? The guy's at Arizona Speed and Marine told me that they took it up to 97mph on Gps and didn't have any chine walk, but they were on a fresh water lake, not the ocean. I have K-Planes and I put them all the way down at high speed but it didn't much good at all, I think the boat is way to much out the water, I then trimmed the drive down which stopped the chine walk but I ended up lossing 5mph in the process. Now to my Question is there something I can do while driving to prevent chine walk or am I just screwed?

LMAO!!! Don't forget this one!!!

I am still alive and Kicking. I took the boat on a 250 mile jury this weekend. The drive is holding up fine, and everything is running awesome. The Chine Walk can be over come by driving skill. I have learned how to correct it up to 97mph, past that i can't control it. I did hit 101 mph on GPS which me happy as heck. 95% of my driving is done below 70mph most of it around 40-45mph. I can't go any faster than that in the ocean with the swells unless I want to play Space Shuttle... I know somebody had a question on how my 5.7GXI can hold that much power, The 5.7GXI is a High Output motor with forged pistons and extremly strong interals, it is nothing like the 5.7 GI or GS motors. Yesterday I changed the pully setup to kick it down to 5psi of boost instead of 9psi. I have about 550hp instead of 650hp, I was burning way to much fuel with 9psi at WOT my fuel burn was 65 gph, Now at WOT I am buring 46gph. I still can hit over 90mph with the 5psi and that is quick enough for me. I will be posting some Video's Clips later on this week of a couple of high speed run's...

BOY THAT'S A LOTTA BULL
