Berny Herrera's report is in... see rotarynews.com

All in all a great, objective article. You'll have to read it. It does beg the question of what the market will think of the RX-8. I for one hope the car is a wild success :)

One side comment that everyone will notice should be of great interest to those of us wondering where Mazda will go next...

"Oh yea, before I forget, the engineer did mention one more important thing; the motor was built to take boost!"

Well, let the rumors begin!

But what type Mechanical, Belt, Gas(Turbo) OR Nitros:eek:
I mean theres at least 5 ways to go with this. And How MUCH!!!!

well, it doesn't really matter how you make the boost, does it?? 12psi is 12psi... but could it take it???

don't worry too much about this yet, we'll know soon enough.

For the same engine and inlet temps 12 psi of boost from an exhaust driven supercharger or a belt driven supercharger will create the same loads upon the engine. Power output will vary based upon the efficiency of the supercharger but engine loading will not. Therefore 12 psi is 12 psi.

Exactly! 12psi on stock twin turbos is completely differant from 12psi on a big single turbo. HUGE differance!

Ladies, relax.

It doesn't matter how many PSI the RENESIS will take and how it will take it. I'm sure one if not many Rotary Tuners will be testing the limits of the engine as soon as they get their hands on some test platforms and we will know these details and more as soon as they get a FI kit together.

I'm starting to think that rotary tuners will be the only way we will see FI on a RENESIS and different tuners will have different thresehold of safety and reliability. As a result, there will be different PSI limits achieved in different ways.

ah, yeah i know that boost and power aren't related linearly, but i wasn't aware that psi and air flow could deviate so greatly... i mean of course as boost continues to increase there are greater and greater losses... hmmmm... thanks. :o
