Don't worry for many years people have rung, telling us they have an RX-7 and when we ask which one they don't know, until  we ask if its the Fast n Furious shape ::)

Yesterday dyno session with friends Rallycross car...

So, we have little problem. Friend rebuilded 13B PP engine. Rotors are Renny rotors now...
It had really long intake with 62 throttlebody. Now it has 50.(unfortunately I dont have picture now)
Header is abit different too... (shown at that pic)

Those are 3 changes made to this thing. So, problem is that it not making enough power. Power and torque curves are identical with previous setup, but just much lower!

Could this header collector be a problem? Well, I know it is but Also, what best lengt for  intake? And how we can calculate optimal for our setup?

Power is nothing without control. Weight is enemy of performance, handling and braking.

Hey jarno, long time no see.

I can't give any advice but I have seen this page before which may help.

http://www.racingbeat.com/mazda/performance/rotary-tech-tips/configurations.html

All I know is the 8 engine is less responsive to exhaust mods because of the side port.

Hopefully the link gives some guidance
