Check this video out! WOW!
Ok, now go to 4:40...You will see the working intake system moving in the R26B engine bay!
Edited..."variable length intake trumpets providing air to peripheral intake ports.."

Paul, you guys are amazing...I did not realize!

Edited due to stupidity on my part...LMAO
It helps to pay attention and actually see the 2 extra rotor housings in the pictures!

No he is saying that there is no variable trumpet intake on any Renesis. The engine they worked on is an R26B which is the same as the engine in the video. The Renesis engine's they work on haven't had any intake manifolds on them in pictures and they'd be stock if they did.

I swear I only saw a 2 rotor in the pics...LOL!!
Now that I made a fool of myself...Whats the possibility of adapting the variable intake to the 2 Rotor Renesis?

To some extent....that's what the SDIAS does. Provides a variable intake tract length
The runners on that engine are designed to be run at higher RPM...they wouldn't work that great for on the street...they would need to be longer for lower rpm function.

Edit: Actually doesn't the SDIAS activate at different RPM's? In other words depending on the RPM only 2 valves are active and at higher RPMS all the valves open giving air to all 6 ports? I heard somewhere that this has something to do with "harmonic tuning". Not sure I just remember something like this.

The variable length ducts on the 26B engine are constantly variable......an ideal situation
Mazda made a system in the Renesis that tried to give the same effect...only in a less complex manner. You can see the results on any dyno sheet. Just when the power starts to drop off...another valve will increase the intake tract volume...and allow more flow...
it's difficult to tune that though...as seen by the dips in power when the valves open....and the variation in A?F as they open as well..
I have noticed that some of the tuning coming out of the Interceptor, and RB seems to do well around these transitions.....better than stock anyway

I always thought the intake system was very complex. It would be nice to see an upgarde to this system. Thanks for the response...I am getting educated.
I wonder what the outcome of turboing an upgraded variable valve intake manafold would be...Are there more gains to be had from the stock intake manafold.

Go Texas Longhorns!
Paul, something else I would like you to look at / ask Rick about.
As you tear down the Renesis short blocks, could you examine the apex seal ends that would sweep by the exhaust ports? I had an interesting discussion with MazdaManiac last night about the effect the heat from the side exhaust port might have on the very end of the apex seals that travel over that spot.
I'm refering the the edge supported by the corner seals. Let me know if that doesn't make sense.
