hey does somebody know is it gonna come 6 port or 4 port:D

 

I do believe it is 3 intake ports and 2 exhaust, thats makes it five right?

 

I can't believe this,

Count em, 2 intake ports, 2 exhaust ports(two on each side of the rotor), thats makes in an 8-port

 

I heard ten a few sites state that there is a 3 intake and 2 exhaust valves per rotor, that means Five times 2 which is ten. This is very unofficial, but this is the site, anybody else have another site?
Renesis Specs MIGHT BE WRONG

 

that have to be wrong, how can be 3 intake port. they can't join the middle plate port.

 

Just goes to prove. you cant believe everything you read on the internet

 

We have to count like Mazda does. My 91NA 6-port actually has 8: 2-exhaust, 2-center plate intake, 4-end plate intake. Since they don't count the center plate, it's still a 6-port??

 

The big difference only shows on some views.
TWO seperate throttle bodies on two separate intake runners.

 

OK - Here it is
Excerpt from 1-8-02 press release:
RENESIS, the key to MAZDA RX-8's front-midship layout, features a side-intake, side-exhaust layout, with the exhaust ports moved to the side housing of the rotor chamber. This allows the size of the ports to be freely set, resulting in an expanded air-intake port area which is 30 percent larger than in conventional rotary engines. This greatly improves intake resistance and contributes to an output of 250 hp at 8,500 rpm and maximum torque of 162 lb-ft at 7,500 rpm without having to rely on a turbo- or supercharger.
In addition, the adoption of dual exhaust ports for each chamber achieves twice the port area of conventional designs and also allows exhaust port timing to be delayed for increased thermal efficiency in the expansion process. Unburned hydrocarbons are retained for combustion in the next cycle, which greatly reduces emissions. A three-stage induction system, featuring shutter valves at the intake ports of each rotor, utilizes the incoming air’s dynamic charge effect and improves filling efficiency, while twin electronic throttles precisely and flexibly control the valve operation. Furthermore, a wet-sump lubrication system with oil-pan height just half that of conventional designs also reduces engine size and weight.

 

yeah, but i just talking about the intake one it is 3,4 or 6 port.:D

 

Its a 6-port

 

4 port Vs 6 port only counts the intake ports... The primaries on all 13bs have been 2 ports (one for each rotor housing), the end plates will either have 1 or 2 ports... so, you add up the number of intake ports per rotor.... thats how you count the ports....

 

ISPY: NECRO-BUMP HAH!It's a 6 port.

 

why you bump up a 8 year old thread?

I was searching for something, saw the thread, and felt he deserved an answer?

RIWWP's on an "all things engine" roll this week. Nicely played!

 

Always looking out for his fellow clubbers. True patriot of sorts. A down right man of the people. Yes, it is true, RIWWP, has answered the age old question for a man in need. To you sir, we salute you, and thank you for your courage in our time of need

 

Plus the free post





Now two!

 

 

wow - 2002 . RIWWP take a bow for answering the oldest unanswered question on the forum

 

 

Why, the dude's probably dead by now anyway.
