I was wondering in what rotor is mostly made in uour cars? I heard it is mainly made in the first rotor so the person that hooked up my MSD said originally it would need 2 one for each rotor but then he said he found out secondary rotor is maily for the emissions. was he right? b/c i see lots of cars fixed up but have bigger secondary injector so how does it work?

 

the person was wrong. 1 rotor is not stronger than another unless its got stuck seals secondary injectors are the 2nd stage, they come on at 3800 rpm and provide fuel to both rotors. they are in the intake manifold.

 

he probably meant the seccond spark plug for each rotor... to my knowledge the seccond plug is mostly to burn off any excess unburnt fuel and therefore reduce emmissions.

 

spark plugs and rotors, thats a pretty big difference. but youre probably right.

 

The trailing spark plug is mainly for emissions. Both rotors make power. Maybe your guy was confused.....

 

I think you guys are right maybe he did mean primary spark plugs but thanks for the help!
