Does anyone know if you can set up a Whipple to work on a counter rotating engine? I'm thinking about running Arneson ASD-8 drives, but I would need to counter rotate an engine to get it to work.

Or is it possible to buy a counter rotating transmission that will handle 1100 hp?

I know I've seen boats with arnesons and whipples...I bet you can change the gear drive in the snout like a regular roots blower and the snout will spin backwards but the blower still spins normal...I don't really know for sure but there has to be a way

That's what I'm thinking. It seems that the easiest way is a counter transmission, but I've never seen them for a performance application. I know very little about arnesons, this is all new to me. I'm either switching to #6's to Arnesons, and I would prefer ASD 8's if I can figure out how to rig them with my hull.

Being I don't know a huge amount about 6's...do they do the counter rotate in the drive like a bravo kinda?? or do they counter rotate a trans??

Why are you wanting arnesons instead of 6's just out of curiousity??

if you read through the different models there are several that are available in RH or LH rotation removing the need for a counter rotating engine...not sure if this helps??

I was ready to pull the trigger on a set of 6's, but they are still prone to failure and frequent rebuilding. For the same money or LESS, I can got with Arnesons, which are far more durable and efficient. As to counter-rotating the engine, yeah, as I've dug into this, no need to do that. I'm still not saying no to 6's, but seeing that I have a fresh uncut transom, I think Arnesons are the better choice.

I gotcha...was just curious...I thought 6's were the cat's a$$ nowadays..well besides like m8's or whatever the "new" stuff is lol
