FYI
My boat was faster and ran better with the 1.36 ratio drives and 28" props. I don't care what all the experts say, I should have never switched to 1.50 drives !!! I will switch back someday when I have some extra coin to blow !! |

That is a shocker! I wouldn't have thought big HP was on your priority list. 900+ a side? That rocks!!! Looks like it will be a real solid 900+ a side too.
Congrats man that is really going to wake her up. She will fly. I bet you'll see mid90's easily. enjoy! Believe me when I say that this was a shocker for me also, as I just woke up one day and said that I was going to add Whipples. Then I decided to change heads and now it has turned into a full engine project. It all started when a buddy up in Ohio did this with his Sunsation and then Bobby Todd started pushing me very hard and I said why not you only live once. My main concern now is outdrives and making them live. I spoke to a lot of folks down at the Miami boat show regarding drives and there are a lot of advancements coming later this year that sound promising. I have two sets of fully rebuilt XR's right now that are ready to go and I plan to be easy on the throttles. My engine builder put it like this. "You will have an abundance of power"! Sounds good to me. |

You should be a little over 92 mph. You are doing the same setup as what I am doing, but my drive heights will make me a little slower than you.

Very interesting project you are doing. I would have never thought you would go with the big power blower motor setup.

Just wait til the first time you roll on the power especially on take off. I know you have driven other boats, but it will be special beacause it is your own and you were used to how long it took to plane out. Now it will be almost instantly up and out!!
Thanks for the information and comments. |

On XR's you change the ratio with the lower
gear set, which isn't as expensive as having to replace the upper gear set.......they're ( the gearset) cheaper than a new set of props. |

You didn't mention what camshaft....is it top secret?:D
"Custom Grind" Mark Boos likes to use a custom grind cam for each application and I have turned it over to him to do what he does best. I'll let you know as soon as I know. |
Sounds like you going to have quite a fun ride for summer Dock. Is it going to be unveiled at the JPR?
