As promised. Here are some pictures.

As promised, here are some pictures I took of the propane turbo snowmobile in development.  This is the Arctic Cat that I believe he developed it on before going to the Yamaha.  I honestly have no details on this kit.  If people want details I can call him up and ask.  But I don’t think they even went to production with this version.  As far as I know they only produced the Yamaha version.  Again, I think these are being sold as Simmons Propane turbo kits.  Not sure what happened to the HP^3 concept.

Propane tank for the tubo kit

Had to post this video

So I was cruising around on youtube and who should be yapping at me?  My dad. hehehe

This is a video of the Simmons propane turbo kit.  My dad is the one that developed this kit.  IIRC, my dad (Steve Benson), Val Simmons, and Brad Story got together an formed a company called HP^3.  Dad was the idea guy,Val was the distributor, and Brad was the publicity guy.  Now keep in mind I of course was not involved at all and may have it a little wrong.  Plus it was a couple years ago.

So dad made the turbo and propane kits.  I believe Brad had someone he knows make the propane tanks that fit under a custom seat.  I’m not sure what Val did on these.  Maybe he made the clutch weights or ported the engines or something.  The turbos my dad used on these are a Tommy Makinen edition Mitsubishi Evolution turbo.  I will see if I can dig up some old pictures I took of this kit when it was first being developed.

Well here is the video.  Hopefully I can find some pictures for you also:
