well now that i sort of understand this concept (haha thanks peng) the zero overlap setup on the 8 is perfect for it because it is n/a right? like you said the reversion thing can get complicated but finding the right amount of overlap for a turbo app, is good. the problem is finding the balance between too much and too little, but then you face the same problem with the intake too

Well maybe my N/A 3 rotor idea isn't so stupid after all, not that they have really nice rotors for them. Now all I need to 2 more jobs to pay for it.

Maybe I could do it out of 13B parts and sell the stuff that I won't be using, and pay for it that way.

And I wonder why mazda wouldn't scrap the old n/a rotors and just supplement the new renisis ones like they did with the new apex seals?

i've been wondering about overlap, but i don't want to delude this topic. I think i will start a new thread.

What ya'll might be forgetting is there is a huge difference between efficient and powerful..

If overlap was such a bad thing for boosted applications then people wouldn't do BP turbos to make more power



Thats all i'm gonna say about this in this thread, RONIN FC has a good idea about starting a new thread on this, since I wanna know a bit more about this subject aswell.

So, I guess the jury's still out on whether or not the renesis apex seals are good for the peripheral exhaust of the 13b? These rotors sound like an awesome option.



As I slowly plan my future rebuild, I'm trying to work out all the details in advance.

Well the problem is that its all still experimental to some extent. But either way im sure you can have the rotor cut for different seals.
