Louis,
Luckily Kaspaas has a duel battery setup in front already, should be easy to do a battery swap(right to left) as the starter on a 7M is on the left anyway. Then move the extra battery to the load bin with a "plug and play" adaptor and battery case.
The biggest challenge is the routing of the ait intake--> through the airflow meter--> through the filter -->to the snorkel and this all has to happen on the right hand side of the engine.
It's not just a straight line you know............
I don't want to reroute over the engine to the left again and subject the piping to unnecessary heat from the engine. (defeats the purpose of getting cool air in from the snorkel??)
Also, are there smaller options than the SFA Donaldson filter that works just as effective?
Keep us posted on Bossie, will need a sound snippet to justify the first roar!
