I've noticed my car has the dreaded humming noise coming from the engine especially in 2nd, 3rd, and 4th gear, whenever I let off or shift. Is there a fix for this or is this doing any kind of harm?

 

Did this start after you installed the JWT's?

 

could be the JWT's...

 

why would it be the jwt be the problem

 

Thank you...
No it's not from the popchargers I know a good bit about cars just never owned a Nissan / Infiniti VQ before. It's without a doubt from the engine.

 

I don't have an MT but sounds like your drowning the gears, sometimes I shift to 5th and then floor it in 5th and I get that same droning sound. Try shifting a bit later say around 3k instead of 2200 (or wherever). Only sound I can relate too so hope it helps. Not the JWTs they have a very distinctive sound @ WOT.

 

Thanks for the input, I normally shift between 3 and 4k and it does it anywhere between there and below. I don't want to shift at 6k everytime I change gears ya know?

Yeah the JWTs sound great at WOT.
