I guess they must make a lower power version for marketing purposes. The example you brought up RC, Kabura must have less hp than an RX-8

Sorry if this is a nub question, but if the castings are identical couldn't you just open up the 5th and 6th port and retune? I realize you would need to get a 6 port intake manifold but that wouldn't be too hard. Right?

I disagree. If they bring a light weight 2-seater to market in addition to the 8, the new car would be upmarket of the 8 to be a 350z/G37 killer. The 8 would be for the people that want/need a sensible 4-door sports car.

So could anyone answer why we could not DI a charge of slurry?
Its been bothering me...and so its going to start bothering everyone else...
I imagine there is a good reason...I just cant seem to figure it out...
Why stop at DI of just fuel?

You're talking about injecting a fuel/air mixture instead of just fuel at high pressure, correct? Well you have to compress that fuel air mixture at some point, and at the pressures we're talking about, that equals ka-blooey!
#60
You are correct on both accounts sir...
The compression of the two together would indeed be bad...during the compression the temp starts to shoot up...you would have to dump alot of the heat produced in order to prevent a failure...
You can get away with the fuel and oil tho...
That said...
DI fuel/oil slurry...
FI for intake...
position the injector in the path of the air jet...to enhance swirling...
K...I'm done meow...

The shape of the exhaust port seems to be different at the closing. I assume the new shape would flow better.

Looking at the pictures more closely, they even made the hole for the 3rd spark plug in the coolant passage.

Optical illusion Dave, i just zoomed in on the pic and saw that the "bridge" ports in the pic was actually a reflection of the main ports onto the shiney rotor housing..

ummm are you sure? looking at what you highlighted, look at where the the 2 actual plugs are and you can see a larger channel behined the thin one at the front. The "3rd plug location" only has the very narrow channel at the front.

I agree. There is no protrusion for the spark plug "channel" for the far trailing plug.
I also can see the 3 improved water bypass channels is the same as the 13B Renesis engine.
I think there maybe is a relocation of the spark plugs becausse of the longer 16x rotors with longer combustion chambers, LDR type? The 4 rotor seems more close to each other becausse of the "bathtube" chambers.

drool... i still dont like that there's only one di injector; even though it's a marked improvement from port injection, the location is not the best for ultra lean, stratified charge combustion.
They could've included a second injector to be able to spray at near tdc right before ignition for a stratified charge lean mixture.
I still love that they are improving the design, eventually more improvements will come.

As it was pointed out by another forum member, the "X" letter may refer to the fact that this particular engine is still a prototype. If this is the case, the production 16c engine may feature some changes.
Then, if these changes could reach the extent of adding another fuel injector per rotor, well, that's another story...

The stock 350z will have 370 RWP in a couple of years.

Maybe that's why we see a 4 port and not a 6. The Renesis intake manifold is pretty tall compared to the RX-7 manifolds. There is alot more room under them. The 4 port manifold especially. It's the 6 port manifold that has the clearance issues as the aux port runners are underneath the main runners. That could make a 6 port intake interesting. They've got plenty of time to change things though.
