    And ^ Rex & his 3 sons that race sport class are all out of Atlanta. Not sure if you know them or not but doesn't seem like they're too far from you. They have multiple spec & GP blasters

    You will really enjoy it. Now if only there were a way to fast forward a few months haha. Are you on the FB groups "waveblaster conversions" or "Sport Boat Racing"? If not, I'd recommend joining those groups. Also - this weekend there is a large group of guys getting together to run some...

    Blaster sport boat racing series

    Powerboat Nationals uses IJSBA rules which is basically same as PWC for spec class. I made 2 Powerboat National events this year and they really are awesome. Top notch race venue, cater bigtime to the racers, pay you to show up and race and the whole weekend is just plain fun.

    WB1 With Turbocharged Spark Engine

    Got the controls installed through hood. Modded exhaust mani and routed to thru hull. Had a waterbox cut and fit but the welder I had lined up wanted way too much to lay a few beads so I'll get a waterbox on it later once I see everything works good. Almost ready for watertest but still need to...

    WB1 With Turbocharged Spark Engine

    That is how the stock spark setup is. Hopefully the existing PTO piece will have enough wall left after threading. I'm more confident in the stock piece being pressed back onto the crank instead of having to machine a new piece... can't tell from the pics but the crank end is tapered ever so...

    WB1 With Turbocharged Spark Engine

    Ok guys, this might be a long post because I have a few big changes to update you on and have some new pics and vids also. Stock Hull Update I pulled the turbo setup out of this stock hull and have decided to make it a naturally aspirated setup. The more I think about it, the more I want to do...

    WB1 With Turbocharged Spark Engine

    Ok so the main holdup was 3 other race skis I had to finish building before last weekend and I am done with that..... for the most part. Racing the last couple weekends has re-motivated me to jump back on this. One thing that has been bothering me is the driveline adapter I made..... I do think...

    WB1 With Turbocharged Spark Engine

    I went into that water log manifold with 3 fittings coming off the side of it and one fitting inline. The one fitting inline will be a pisser so I can see that I have cooling into the exhaust piping. The 3 injection point placement in the exhaust was mainly because it was easy to get to that...

    WB1 With Turbocharged Spark Engine

    "meaningless silly statement"?? Alot of people on here don't know turbo lingo so sorry for breaking it down to where joe blow can understand a general statement and I wasn't even comparing turbos! I was simply answering a question on what kind of HP the engine CAN make - I was not asked what...

    WB1 With Turbocharged Spark Engine

    Basically there is 2 - 1/2" cooling lines coming from pump. One goes to the engine, one goes to the intercooler and then into exhaust manifold. From the exhaust manifold, everything is waterjacketed all the way up to the hump in the exhaust over the driveshaft... Then water is injected into...

    WB1 With Turbocharged Spark Engine

    A naturally aspirated spark engine makes 90hp factory - 110hp reflashed A turbo canam maverick has the same exact engine but uses 10.5:1 pistons instead of 11:1 pistons that are in the spark motor and the maverick makes 172hp at flywheel stock - 12ish psi. A turbo spark engine is 250hp capable...

    Blaster Kawi 1100 Tuning help

    Just came across this. I basically have the same exact mods done to my blaster with kawi 1100 except I am running Mikuni 44's. Scottie Mac helped me with jetting specs a little over a year ago and it was right on. I am at sea level and using same needle/seat/spring with same popoff Pilot 120...

    WB1 With Turbocharged Spark Engine

    Yep, Sport GP legal. The rule is 900cc with forced induction. I'm unsure if I will have it ready to race for April 21 in Baytown but I would think by May for sure. I could probably have it together but still alot to do to hone in on tune and rideablility once on the water.

    WB1 With Turbocharged Spark Engine

    Thanks guys, I am real close to doing a startup... just a few small things to finish.... turbo support, painting inside the hull and a good final assembly. I will still have to secure top deck back on and install gauge into the hood too. This project has gone on alot longer than I would like...
