Blaster 200 HP Carbon Fibre Blaster with 155mm Pump

[Carbon Blaster]

It's been a busy time at Infusion T over the last year, but we have finally finished building our 2nd Carbon Blaster.
Our 1st Blaster received great feedback from all who rode it, but we wanted to see what would happen when you implant a 200 HP DASA motor & a big pump - so stay tuned for the ride!
This has been a group build between Infusion T, DASA & Power Factor, so firstly we have to thank DASA for supplying an awesome 1100cc 16mm Billet stroker motor & Mark Baxter, the man behind the incredible Power Factor Pipe, for supplying the pipe & waterbox.

The basic overview of the ski is as follows:
Solid carbon fibre with kevlar complete custom ski.
200 HP 1100cc 16mm billet stroker motor.
Power Factor pipe with custom waterbox.
155mm 12 vein set-back custom pump.
Flame total loss programable ignition.
48 Novi carbs.

Here are some of the mods to the hull..

Sick!!!!

flatwater blaster flip?

That's it? You damn tease.

I guess its a race hull? Would be awesome to see one for freestyle in carbon with this drive train. Imagine what Zimmy would do with that!!!! Holly F!!

 

[tshank123]

Subscribed. Same question, is this a race or a freestyle build?

 

[Carbon Blaster]

We made both Blasters as surf skis.
The 1st Blaster (pic below) spent the initial testing on the river to iron out any bugs. What was a worry is that it railed & handled the turns so well, that we thought we had made a race hull, not a surf hull.
We were so nervous heading to the surf thinking that maybe it would bite in too hard, get smashed around because of it's 36 KG weight redustion & basically handle like crap.
Fortunately are fears were wrong, it loved the surf!
You could turn on a dime if you wanted, you could slide, the ramped nose launched you off the smallest amount of surf & the semi - v in the nose allowed you to hammer as fast as you want through the chop, without getting bounced around like a cork & the new positioned pump gave you constant hookup even in the choppiest of conditions.

what size pitch prop you gonna start at for that 155?

 

[sjetrider]

Nice, but a rockered nose and shortened rear with the setback pump would have made it even more fun LOL. Sounds like a nice all around hull though. What does the complete boat weigh in at?

 

[Carbon Blaster]

This is the glass hull we used to chop up & do our mods to before we can make the moulds.
The nose is ramped & semi-v'd. The side view of the complete ski above gives you a better indication of just how ramped it really is. It's not super noticable in this pic as we spent a lot of time blending the nose into the rest of the hull

 

[Carbon Blaster]

This pic shows some of the mods we did to the rest of the hull.
The complete pump/intake unit has been cut out, modified & moved back 100mm.
The pump tunnel has been re-shaped.
This pump tunnel was modified for the 144/148mm pump, we re-make this area later to fit the 155mm pump.
The roof above the pump has been re-made to run a Raider push/pull trim cable directly above the steering nozzle. This gives you the lightest, most smooth trim you can ever feel & you can run a Raider/GP trim system.
The chines have been re-shaped & the rear transom shape/length has been changed to allow for the massive weight reduction of the hull & to help with stability.
The ride plate rails have been re-shaped to fit the custom ride plate.
The complete hull has been trued including better alignment of the pump/shaft.

Skat-trak made a 7/15 swirl to suit the custom pump they made. I thought this would be too short, but they said to try it first before we judged it.
We had the ski on the water last night for it's maiden voyage, the motor needs a good 7 hours of run-in before it starts to spring to life & then a proper tune, but initial feel was it didn't feel under-proped. Need to test when it's run in, then compare to 15/19 or similar.

The shortened rear end felt like crap on such a light ski, unless it's whole purpose is a flat water freestyle hull.
The nose feels awesome & the pump is set back 100mm, plus the new 155mm pump tunnel is longer as well, pics to follow shortly.
Weighed all the ski pieces individually (hull, top deck, bulkhead, hood, etc) & compared to a non-reinforced stock Blaster ski & had 36 KG difference between the two.

 

[Carbon Blaster]

This is the hull ready to be vac-bagged.
The layup is solid carbon/kevlar, not a layer of carbon on the outside & inside sandwhiching a fibreglass core.
Different types of carbon is used to get strength, rigidity & flex in particular directions.
Over 50 test layups were made & tested for weight versus flex & tensile strength.
Each carbon part of the ski was made this way as each part can have different flex characteristics than the other, eg: you want the hull base & sides to have a certain amount of flex to absorb heavy flat lands, but you want no flex in the drive line. You want no flex in the bulkhead, but want some flex in the seat base, etc.
The process is "Resin Infusion" which means you load all your materials into the mould dry. Because your not racing to get your materials in the mould before your resin gels, you can take all the time you need to position the materials just where you need them.
When the materials are loaded, resin & vacuum lines are stuck down, then followed by a vacuum bag.
All the air is sucked out of the mould, the materials are worked into all the tight corners, then the air is sucked out of the carbon.
Once you have achieved a good vacuum with no pin hole leaks, a special epoxy is sucked into the mould under vacuum. This resin is purpose made & is very light with viscosity, like petrol.
This allows the resin to wet out the carbon fibre, but not "pool" anywhere. Only enough resin penetrates the carbon to wet it out, the rest goes into the vacuum lines & flow mediums.
The carbon is vacced down untill the resin hardens. The vac bag, resin & vac lines, flow mediums, etc, which all contain the excess resin is removed & the correct resin to carbon ration is achieved. this ratio gives you massive strength & lightness.
The carbon piece while still in the mould is now baked for 8 hours, which adds greatly to the tensile strength, before being removed from the mould.

That's it? You damn tease.

You have to hold out just a bit longer to see your work, but you know it will be very bling!!

I have to say I have stalked this boat on the OZfreeride site quite a bit! I would love to see a carbon surf blaster here in the states at some point! its nice to see you guys stepping out with some big motors and hull mods for the the blaster community!

Keep us updated on the build!

 

[JetManiac]

Love the innovation and experimentation!

Thanks Zimmy!
Dasa & Power Factor were pretty excited when we spoke to them about the project. We said we wanted the best of the best in this ski & even though it's way overkill for such a lightweight ski, we thought why not!
The 1st blaster had about 130 HP with a mod 144mm pump, when you hit full throttle at low speed, it jumps out of the water.
This ski has 70 to 80 HP more & a much bigger pump for hookup, so it needs to be about throttle control for sure, otherwise death could come early.
Even though we were just running it in last night & running super rich, it did something that caught me totally off guard that I have never felt with another ski before (blaster or standup).
Just did a little low speed bunny hop & the short time the pump was out of the water, it must have been enough to clear the richness of the motor, when I landed I hit the throttle again (expecting it to be all choked up still) the nose came right up on me.
Instead of just going into a 2nd bunny hop, it took off & stayed with the nose in the air exactly as if you were doing a wheelie on a motocross bike.
When I came back to shore, the guys that were there & myself all looked at each other & said "What the ###### was that???"
I suggested that once the ski is run in & tuned, I think we are going to need velcro gloves for this thing!

 

[Carbon Blaster]

This is the bulkhead, we put heaps of work into re-designing as there was many things that could be changed:
Much lighter than lead anchor smc stock bulkhead.
Ribbed shape for stiffness to reduce thickness & weight.
Duel exhaust holes to enable exhaust to run either side or twin exhaust.
Holes either side for water lines, steering & trim cables.
The hole for steering cable is positioned to allow the straightest route to reduce binding for smooth steering.
Twin cutaways on bottom of Bulkhead to quickly move water to rear of hull.
Top of bulkhead open to greatly increase air volume in hull & easy access for cables.

 

[zimmy]

I like the bulk head work! are you buys making any plans to produce these at any point? Estimated cost on the carbon build once all is said and done?

I would love to see some video of this hull in action, I have seen some pics of it, but havent been able to find a video yet! Keep up the nice work!
