timing belt whine...

[lloydxmas]

So I get my r32 gtr up and running and I hear a faint supercharger whine noise coming from the front of the engine, after narrowing it down I find its the sound of the timing belt. I have replaced everything on his motor, it is fresh with all new oil pump,timing belt,tensioner,spring,idler pulley,idler bolt. My question is we have went through a couple of times and cant totally eliminate the sound, I have set it a few different ways. 1 being extremely tight which caused the noise to be loud, now I have made it a little quieter but it is still there. I searched around and found that some people say it tends to be common with kevlar belts (I have a Power Eneterprise kevlar belt) also some people say it is also common with cam gears that are worn (I have a set of older Tomei cam gears). Lastly I have read that the belts tend to quiet down after you get some miles on it. Can some one put me to ease with similar situations?

when i first did my belt i heard the same whining, however mine went away after some driving. not sure about kevlar i used an oem belt

is the noise very loud (like a screeching sound) and constant?? In my car i had a loud whine every time i would start the car...i later found out it was my alternator belt...i made it tighter and the noise was gone. IF not then...no idea could be kevlar belt.

is not a drive belt they are off, I eliminated that problem, its mor elike a faint supercharger sound. The motor has been together for a few months now and Ithe car has been a huge restoration and mod ordeal and is my first rb series car. I am hoping once on the road it goeas away after some time for it to wear in.

i think it just needs to wear in a but drive it for a bit if it still makes that noise then go mad and try to find the problem

My timing belt whined (rpm dependent) when it was too tight.

[Speeddm]

Belt is to tight.

[lloydxmas]

so how loose does it need to be then? it basically has no tention on it now, just enough to be able to twist the belt a quarter-half twist... The tensioner is set at about 5:30

You should be able to move that belt half an inch to an inch up and down between the cam gears.

[lloydxmas]

you mean between the cam gears up top I should be able to twist it a half inch or physically pull it up a half inch?
