    Re: Waveblaster 1 with Turbocharged Spark Engine

    Billy Dearman’s Judge built Kawi stroker bullet is the fastest waveblaster I have seen with my own eyes. Right at 70mph. It is ridiculous. Sam’s Wammer is pretty close and may leave harder off the line. Basically, when the two of them race, it comes down to who gets the better start/reaction time.

    I think Sam said his Wammer hull was right at 66, but I believe this was before he went EFI.

    Re: Waveblaster 1 with Turbocharged Spark Engine

    Would love to put this powerplant in an AM blaster hull one day. Wonder what has been the fastest stock hull blaster?

    Fastest I have heard was around 62mph. Stock hull is really hard to get speed out of past 60.

    Re: Waveblaster 1 with Turbocharged Spark Engine

    Was about time that I re-group and update my "schedule". Helps me stay focused on what I have to do instead of bouncing around between a few different things at once and taking longer to complete each thing. The list on the left is categorized on what I have to do with estimated durations for each activity and over on the right is a gantt chart showing the order things will be done in. A few of my friends ask me how I have so much time to do builds like this and the reality is that I don't have much time, I just get a good plan together so I know exactly what I need to do to hit it hard once I get an hour or two to mess around in the garage.

    Re: Waveblaster 1 with Turbocharged Spark Engine

    Are you doing any internal engine work to compliment the turbo? High compression? Port and polish, bored throttle body, stroker?

    Re: Waveblaster 1 with Turbocharged Spark Engine

    ARP headstuds and thats about it. It already has high compression 11:1 pistons. Engine mainly just needs to be able to handle the boost. I do plan to race this in my regional IJSBA organization so 900cc with forced induction is the limit. More boost will make up for anything not done internally

    Just got the turbo piping back yesterday and it was migged instead of tigged like I asked. I could've migged it. Anyway, I need to dremel the v-band flanges some because of the heat distortion from welding. I'm going to focus on another project this weekend.... dropping a 760 in my new superjet. I can do that fairly quick and then will continue with the turbo project

    Re: Waveblaster 1 with Turbocharged Spark Engine

    Been having so much going on between work, family and other smaller projects the last couple months but time to finally get this thing finished. Things I got accomplished over the weekend:

    -used a dremel tool to put some fine touches on the v-band flanges - they are the vbands that have a male & female side and the heat from welding had them not wanting to fit together by the least bit.
    -clocked compressor on the turbo to the position it will be ran in
    -fabricated the rest of the exhaust piping after the "hump". After the hump is non jacketed but I have water injecting into it
    -welded in 3 bungs for the water injection - long straight piece of the downpipe
    -machined a water injection distribution block. Water will come from the last fitting on the jacketed portion of turbo piping - 3, 1/4" outlets will get injected into downpipe to help quiet it down some and also have some water before the coupler at the thru hull - a 4th fitting will be on a "pisser". I will have a jetworx restrictor where theres just a tiny bit of water going out the pisser and 90% of the water going into the downpipe. Main reason I want a pisser for the exhaust piping is so I can always know its flowing.

    Re: Waveblaster 1 with Turbocharged Spark Engine

    Awesome build! I have thought of an adapter/coupler for the Yamaha drive for my own project. My concern is the impeller shaft creating a sine wave or oscillation, because the coupler is forward of the bearing. And the shaft to the motor pro is on a pivot, unlike the Yamaha with the crank bearings to back it up. Maybe I'm overthinking?

    I get what you're saying but with everything aligned it shouldn't be an issue. Now if the midshaft stuck out far from the mounting point then I could see that being an issue. I know a guy with a spark turbo SJ that has a pretty similar setup and he has ran 18psi with no issues. Anything could happen but I'm confident in the setup
