what about axial flow turbo chargers? Like a side-by-side kind of design with gears?

I actually have learned some interesting info about the effects of turbos vs superchargers on the engine itself and it is only unique to the Renesis. I'm not going to get into it as it'll start a debate and I'm not even going to say which one it may or may not favor. I need to do more research into the topic but it was interesting to say the least.

Turbos...due to the high amount of exhaust energy available in the system which could be utilized...

I even read a tech document that even the author exclaimed "turbos and rotaries were made for each other"...

Better still, ditch the gears, and put them on a common shaft...

And all of a sudden we've invented a gas turbine / jet engine

Cheers,

Aw C'mon Fred. That is a bit of a strip-tease isn't it?

Cheers,

"Drunk" pissed, or "pissed-off" pissed??

Neither actually. Just working on a pet project at 5:25 am - in your future

I think we are having the "pissed" conversation in another thread...apparently kiwis are also fond of using the "bald as a badger" line..."pissed as a newt" still makes no sense however...

He said unique to the Renesis though, not just all rotaries. I'm thinking it has something to do with the backpressure created by turbos and the side exhaust ports.

Is that close??

or maybe it's not the backpressure, but the heat being generated from the turbo that could cause the flat housings to swell and possibly pinch the rotor a little?

Who's got the waterjacketed turbo manifolds?!?!

The Renesis has no inlet/outlet overlap.

With an overlap, a supercharger can displace the remaining burnt gases with fresh gases in the combustion chamber relatively easily (increasing volumetric efficiency), since it works against little backpressure (as opposed to the compressor wheel of a turbo, which works against a relatively high backpressure).

The whole...a turbo mounted close to the exhaust ports increases the residual heat in that area which then degrades* the area over time until it causes a total failure???

degrade - warping, missing material, dishing, general craptacular heat related stuff...

yeah, that whole bit, there are ways of dealing with it that I'm not as knowledgeable on as of yet, but there are ways.

Lots of ways...if you are really concerned about it...move your snail away...if your REALLY concerned about it...mount it far out back...roto-rocks style...

There's more unique to the Renesis than just the location of the exhaust ports.

I've got my popcorn and diet coke - this is turning into something really interesting - keep it up.

If no one has figured it out by Sevenstock, I'll think about spilling it then.
