Time to make room for the intercooler . Still has alot of finishing work but it should catch some cold air maybe even enough for a turbine!!

I knew you could swing wrenches but I didn't know that you could do body work too...:cool-smiley-011: |
Hopefully have it painted by the weekend. Once done ill post more pics with the front grill and rear doors installed. I have to give Rick some credit pushing me to do it and with some tricks of the trade. I got the scoop idea from the 36 nortech. Thats my next boat that I cant afford so Ive decided to get one piece by piece !!
Started by shaping foam and covering with glass. |

Nice work Mike.

my vote is for the turbine.
fuel burn is less for the turbine at full throttle. Reason for the 4 fuel tanks is because I hate stopping to get fuel, and its not too easy to find Jet fuel on the water. |
Dino,
I have a question about the gear reduction box on the turbine. I know the one you have reduces the Turbines RPM's to 6000. Is it possible to get one the reduces to 7000RPM ? The reason I'm asking is because there are some boats out there running big motors, such as On The Chip. I believe Curtis's motors are capable of turning well over 7K. They were built by Jeff Cropper, J C Performance. As far as the additional 1000RPM. I don't see the turbine having a problem with the torque needed for the xtra RPM. And it might yield more MPH. As for props. Jeff has quite a few props for #6 drives. He brought one by for initial testing. I'm sure if Skippy doesn't have the props needed, Jeff could help you out with the dialing in. Jeff is one of the most experienced drivers in a single engine performance boat going over 100. |
My money this year is on Zul 1st Turbine 2nd Rob 3rd and myself 4th. Whats the vig on this one ?

Rick,
The output reduction gearbox that I am using is the same mil-spec gearbox that was designed for the engine and used on helicopters. I don't think that there is one that runs at 7,000 rpm. If you wanted, you would have to have one built to reduce from the 20,000 rpm turbine speed to 7,000 rpm. Do most other high performance boats use some kind of gear reduction after the engine, either in the transmission or in the drive, so that prop speed is less than engine speed? How many boats have props that are turning at 7,000 rpm? Dino |
