I'm particularly interested in the possibility of keeping the valves clean with methanol injection.
It seems there could be a large benefit there other than just a power increase.

this is a problem on all the FSi engines, not just the RS4...
my tech (off the record) has suggested that the carbon buildup on the intake manifolds may become the engine equivalent of the RS6/4 DRC issue before too long. AoA is going to have to do something to address this.
