I have a turbo ls/vtec that has 1000cc rc injectors. The car puts about 505whp to give you an idea. When the car was built I had thought I was injector noise but then some people are telling me that it might be my head. Or maybe needing a valve adjustment. The noise is not crazy loud like something is broken but you can still hear it. Do yall have injector pulse noise?

 

1000cc injectors at idle are opening/closing very slowly. i doubt you are hearing that over the valve train noise.

even if its not at idle the ammount of engine/valve train noise on a b-series cylinder engine is alot. what you may be hearing is just the valve train working away.

do a valve adjustment and see if what you are hearing goes away.

 

i know my DSM's are loud.

But yeah try a valve adjustment and see if it helps. I mean it couldn't hurt.

 

ive never heard a set of injectors as loud as 160lb injectors.

perhaps you need some new LMA's

 

well I was thinking either lma's, injectors, or maybe just needing a valve adjustment. How could I check if it is the lma's or injectors??

wouldnt they be opening and closing as fast as possible for a very low pulse width because at idle fuel requirements are very minimum on those sized injectors.
