Chris, Since that video I posted showing our EFI running, we have seen as much as 53HP. Modena’s claim of 55HP is entirely plausable. The interesting observation we are seeing is that even while making this much HP, the internals of the engine are actually showing less stress and evidence of superior lubrication. I can post a dyno curve if required, but from what we are seeing, EFI is great and looks to be possible in the very near future.
I’ll have to agree to disagree with you about the numbers, but I do agree EFI is the way to go, my newest superkart is going to be an EFI….
