I think I should have stopped at 12.5/second, since there’s one coil per cylinder.

(Now Rusty has me correcting myself)

Yes, that’s the beauty of a V-8.  Also, 1500 rpm @ cruise would be in OD mode.

 

Rechecking my math again…

V-8 LS1 Engine

Cruise rpm – 1500

Each cyl fires once/2 rev = 750 firings/minute

750 Divided by 60 sec = 12.5 firings/second

12.5 divided by 8 cyl = 1.56 firings/coil/sec

 

Rotary Engine

Cruise = 6000 rpm

Each rotor fires once/rev = 6000 firings/rotor/minute

6000 divided by 60 sec = 100 firings/second/rotor

 

Rusty, please check my math.  ;-)

 

That’s a big difference!!!

And do you really cruise down the highway at only 1500 rpm?
