ratio directly on the drive shaft/eccentric shaft. At each face, fuel is
trapped, compressed, fired, and exhaust releases
2.What's a boinger?
> Reciprocating engine

3.Why does a rotary engine make as much power as a boinger twice its size?
> Direct torque. Rotors are placed directly on the "crank" shaft

4.Why does a Renesis make so much more power than prior rotaries?
> Efficiency and side mounted exhaust ports to burn off all fuel

5.How reliable is a rotary engine?

22.What should my engine's compression be?
> Hmmm http://www.mazdatrix.com/faq/rotorwgt.htm

23.What are the differences between earlier & later Mazda rotaries?
> A lot, depending on what years we are talking about

> 4 port are more commonly found on Turbos, 6 for N/A

25.How do I tell a 12A from a 13B?
> Engine code can be found on top of housings

26.What is a thermal reactor?
> What catalytic converters used to be

27.What's the best way to test changes I make that affect my car's power?
> DYNO

28.What if I switch to a light flywheel?
> Less momentum on shifts. Revs quicker, but shifting uphill is

difficult
29.How do I get the old flywheel off?
> Get a Mazda flywheel puller

30.How hard is it to stop oil from leaking?
> HUH?

31.O-rings? What o-rings?
