When using the R1 engine, do you use a different battery and generator/alternator setup to power the extra load from the car electrics, or does it cope without any changes?

Just use the R1 set up, should be fine.

Cheers, even better..........locost solution

I use the R1 set up with no problem. never need to charge the battery even though i hardly use the car
