RX7 Rotor Housings on Renesis Engine
#51
Rotary , eh?

why not leave the center port and add a p-port as well?
Do you think a small p-port be added in a location as to not induce overlap. I wholly agree with RG on the no overlap subject. Lot's of intrinsic benefits. And it seems you could add a lot of exhaust flow without messing up the idle such as in an overlap engine.

Because we could keep the exhaust gas speed up by shutting the centre ports off completely - and gain more of the benefits of having overlap + tubular headers, if you do end up with some overlap - due to getting rid of all that turbulance and mixed pulses from both rotors.
I'm one of the few people that are racing in a series with unlimited N/A mods and no turbocharging, so overlap isn't as much of an intrinsic problem for me as for you lot anyway.

Furthermore, I'd take anything from either of these two companies with a grain of salt. Funny how they always claim 20 hp with parts everybody else only sees 2 or 3.

Secondary gas tank?
Did anyone notice the small gas tank with several lines sitting right behind where the rear seat goes?
How would that be?
A small tank filled by the stock pump, from that tank we make a real fuel system.

bump ... but what about adding a small pp exhaust so as to not induce overlap? maybe I iz a confused noob, but it seems like everybody dismissed that without saying anything....
also: rx7 1 piece seals in the rotors to help with the concerns of wear over a pp?

After reading the whole thread, and the various ideas thrown out, I am wondering something about the center port flow and something I noticed about the 16X. From what I can tell, the 16X is the same length as the Renesis (either S1 or S2) despite having narrower rotors. If that is true, then it seems that some other part must be getting wider to compensate for the reduction of width in the rotor housings. Again, if true, could it be that the center housing have been made wider so that the siamesed center exhaust port could be either separated or at least be reshaped for less turbulence?

I was simply trying another mental angle to wrap my thoughts around the originally posted idea. It's what I do to noodle these things out. I ask questions, often very hypothetical, in the hopes that someone with a better understanding can tell me, "No, you're wrong because of A, B, and C," or "That's actually something I know or understand to be true." It was not an intentional threadjack; but was just me trying to better understand why a hybrid Renesis/13B might be capable of some advantage.

seems we need varible exhaust flow, like the intake ports opening and closing at different RPMS
imagine haveing valves to keep the exhaust P-port closed, then at higher rpm it opens?
