Has anybody read the article "Backwards Engineering" in the December 07 Sledheads Mag. The author, Claude Beaudoin, reversed the engine in a Doo 1000 SDI thus having the exhaust exit under the seat like the Yammis. He also goes on to claim a loss of 50lbs and an engine output of 215 hp. Has anybody seen this done? I'm a little skeptical on it. Also if the exhaust comes out under the seat what did he do with the gas tank to allow it.

I have seen this done only it was a polaris 800 motor. Can't remember the name of the company that had done it. They had it on display at the jackson hill climbs about 2001 or 2002. Maybe someone else on here will have some pic's and a little more info.
The Team Fast Blade used the Poo 800 and mounted it backward. So did the super rad Redline.
when you say reversed, did they just change the direction of the motor? or was the pto on the same side and modified the cylinders and head to have the exhaust and intake switched.
I know that for the blade, they changed the orientation of the motor so they could run there gear to gear chain case.
Sounds like a lot of work to go the other route, modifying the engine itself. Pictures would be cool to see.

Way back in '93 or '94 Bender racing lopped a cyl off a V-max 4 turned it around and raced it in the formula 3 class. I had a magazine with that sled in it not sure if it's still around. I'll see if I can find it.
In the article the author didn't explain how "how" the engine was switched around. He did explain a few of the positives having a reversed engine; he said with the exhuast going straight out the back that clutch heat related problems that normally affect sleds becomes mute, along with the exhuast becoming blocked while in the powder. With exhuast system out of the engine bay it opens up a ton of room for a larger and cooler intake system (K&N conical style airfilter, with a 30cm by 25cm by 30cm air box. with this "new" exhaust system he was able to run with Rev body panels on the RT sled.
