RXT 215 LPG conversion
So here it goes....
Sitting at home in the cold and dark winter months we have in north Europe ideas are being born. Next months project will be to convert my RXT 215hp to be able to run on LPG. Info needed to know is that this ski is used for flyboarding so a heavy metal tank for storing fuel is not a "big" problem...
Idea are to route hardpipe for supplying LPG injectors to the back of the hull and put a quick connection somewhere arround tow hook. One thing could be to doubble up the routing also to the front for possibility to connect 2nd fuelbottle in the front trunk in parallel with back one.
I think of using EU style bottels due to avaliability arround 28L each so 1 bottle arround half oem gas tank. When going flying no problem to have a coupple of spare bottels that are filled in the back of the car and be able to quick replace when running empty.
Control diod / panel to be put somewhere in the oem dash for speedo. Size is only arround 1.25 x 1.25 inches.
Install vtech O2 sensor for LPG ECU to be able to correct f/a ratio.
Build bracket at the back of ski for 1 (maybe 2 tanks if not to much weight). Quick strap for connect?..
Basically it. All ideas are welcome as I want to start making some drawings and start build ASAP. Especially regards back mounting brackets for LPG tank on back deck...

A little bit of aussie humor:
Its crazy but I like it.
I think it would be worthwhile to fit an EGT probe in, using the RAD4 plate (as found in the greenhulk store) as the mounting point. You might want to use this information while tuning.
If you can't get a decent EGT probe somewhere locally let me know.
I'd just like to suggest caution maybe on the exhaust side valves. The rest should be OK.
Did you try the important test yet? To see if the 28ltr container fits?

Make sure to use all aluminum LP tanks, to fight corrosion, and for weight savings.
We run LP regulators on 4,& 6 cyl engines in forklifts with a mixer carb. One forklift tank can last about 4- 6hrs of continuous use on them.
Good luck with your project.
