The rest of the materials came in while I was on vacation so I worked on it a little bit yesterday while I had a few hours. Gas tank mounts glassed in, oem spark tank straps is what I used and the tank fits nicely, even with the front foam in. Started fabricating the water-jacketed uppipe and...

Just been waiting on parts to come in this last week. Rest of the flanges and fittings should be in next week. Leaving for a trip to Colorado tomorrow so I probably won't be jumping back on this until next weekend. I did shave the stock gas tank/waterbox brackets off and set the spark tank...

Awesome! I was about to go to a rear box but now you got me thinking!

Got the gas tank & waterbox brackets grinded down smooth. Glassed in the mounts but still need to put 1 more layer on the front and rear sides. All turbo piping, fittings and hoses ordered... just waiting for it to come in. While waiting, I can still grind the glue down where the hull was...

The engine is a running engine but theres alot left to do in this build. I got all the piping, hoses and fittings ordered to build the turbo setup

Yeah you aren't kidding... I didn't include any final assembly or tuning. I'll add it on there to keep track of totals... I keep track of costs but this will be the first build I keep track with labor hour totals. I know someone in New Zealand with a turbo spark SJ and they are using a 144...

A little to update. Got another Spark engine in a couple days ago. I've been letting the motor mounts glue dry and the ski was at my dads where I did the motor mount work over the weekend so I brought it home yesterday afternoon. •The Spark gas tank fits up front pretty good and I may be able...

Dang, I had a long typed out response but it didn't post with the pics. I'll try to shorten it up some... Spark engines will usually run you between $1500-2500. Turbos need lubrication.... Most of them use oil but the one I'm using for the blaster is a special oilless turbo that is lubricated...

These are pics from my turbo rxp-x turbo system. I'll explain more in next post

Alot of people told me the same thing too about the driveline coupler. People thought the bottom of the motor would be on the floor of the ski before the centerline between engine to midshaft was achieved but you can see that it works. I've seen a turbo spark engine in a superjet out of New...

With the turbo that motor is capable of 200+ easy. Closer to 250 if fully built and pushing 20+psi. Stock form you can have it flashed to 110hp on 93 octane.... 5-10 more hp if using race fuel or e85 with a more aggressive tune

Thinking I'll turf the outer edge, put a seal around the inside and then bolt it back together similar to a spark hull so I can remove it fairly easy if I needed to

Working on uploading some right now

Months of brainstorming and finally made a good start to the project over the weekend. Hull is split, engine mounts are in and should start fiberglassing mounts tomorrow. Will be using a Comp oilless turbo with tial watercooled exhaust housing and Motec M130 for engine management. Stay tuned

The Watercraft Journal did an article on my 701 sport spec waveblaster that I recently built. Hoping to draw some attention to the sport skis and gain new racers with the low cost of entry for a basic spec ski. Check out the article here...

Hey Bill, I just saw your PM and can respond to you here. The blade style JCracing/3dDesign sponsons are awesome. The Jam sponsons are good but for me, they bite a little too much and you don't have to lean the ski over as much for it to turn hard. With the blade style sponsons it will let...

Thank you, that is what I am looking for

Bought a bigfoot beach cart that is the 4 wheel version. I bought the frame only and need to get some wheels/tires on this thing. Trying not to spend $90/wheel & tire and honestly, I only need a turf style tire.... it does not have to be the balloon tire. Where can I find wheels that have a...
