Greetings duners! I have been getting A LOT of questions regarding the mysterious Oregon dunes based rocket powered Yamaha Raptor. Well, it's mine and it's the read deal. My raptor started life as a newly purchased 01. I then changed the tranny to an 02, had ALBA port it, drop in a 700 12:1 piston, install a gorrilla rod, true and weld the crank, put in a Plasma booster, K&N intake and ALBA exhaust. It was ok, but not enough. So, I then installed a wet NX NOS system set to a 30HP hit. This required my beefing up the drive train to stainless, extending the swingarm +4, widening it 4" with a Lonestar axle and +2+1 a-arms, then going to a Works Pro Series suspension to handle the added ponies. As my allowance permitted, some look-good stuff was added. Power wise, this wasn't enough either (I apparently have issues, according to my wife). So, I built a solid fuel hybrid rocket motor capable of 300lbs of thrust. It uses PVC as the fuel grain and O2 and NOS as the oxidizer. I can throttle it between idle and MAX POWER. It essentially assists the motor, but will not push the ATV on it's own. It's mounted on the swingarm and made to be disconnected rapidly for race application (sand-drags). It's designed to vector the thrust slightly upward the faster I accelerate so it keeps me planted. The guys at ALBA made a music video of it and it can be seen at www.albaaction.com. My current project is the development and installation of a supercharger. It's already installed and I ran it on the DTR dyno, but we had fuel scheduling issues. So, I am making an injection system to run with the supercharger. Wish me luck. Take care and have fun, fellow duners!

 

I've got to see this thing!

 

Your Raptor has surely been a hot topic amonst many ATV forums on the internet. [img]i/expressions/face-icon-small-wink.gif[/img]

 

That is one nice Raptor there. Looks like you had a close call on the video.
That guy must have road back to camp to change his pants after pooping in them.

 

talk of the internet try around camp, we keep wanting to break out the marshmellows and dog for roasting.[img]i/expressions/face-icon-small-happy.gif[/img]

 

hey you better watch those 30 hp jets i'm stuck at 25 without the jets[img]i/expressions/face-icon-small-smile.gif[/img]

 

That is too cool.[img]i/expressions/face-icon-small-happy.gif[/img]

 

Afterburner,

I admire your creativity but I have some curiosities concerning your bike. First of all, I am curious how an engine (rocket) which is uncapable of propulsion of the vehicle on its own power is supposed to assist the motor in any discernable way. My understanding of physics and the laws of summation of forces leads me to believe there would be no advantage. Also, you mentioned being able to throttle the thrust of your rocket. How can you create a variable thrust with solid state fuel? I am also curious about the fuel itself. I would assume that you would have to use a fairly large amount of PVC. Isn't there a risk of releasing gaseous polyvinyl chloride (a very deadly gas) into the surrounding area?

Ill race your "super fast rocket raptor", when you going to be at pismo next?....

 

Yeah , what he said, Bike looks nice but Im calling bull$hit on the "rocket" however it is original [img]i/expressions/face-icon-small-smile.gif[/img]
