I have recently purchased a 2004 Grand Prix GTP Comp G with 46k on it. While slowly accelerating the I can hear the supercharger whine. Is this normal since the engine is not under heavy load? It only whines while accelerating (not while turning or at idle). I just wanted to make sure there is nothing wrong with it. Thanks

under light throttle youre producing a couple pounds of boost. itll whine.

It's a beautiful sound! Get use to it. =) Wow a 2004 with only 46k! Thats really low miles for the year. Good Deal.

alot of times its power steering or the torque converter you are hearing, i doubt with a stock air box and stock pulley you will hear the charger whine much. i got a few of these grand prixs, gts and gtps that i nick name crybaby for this whine they make(stronger than most) they all run fine with no issues. i do not think you have anything wrong..btw use only premium gas in your gtp! =)

If the whine bothers you, turn the radio up! lol

Why would it make boost under slow acceleration, that doesn't seem right... I don't make boost until like half throttle.

I like that, that would be a cool window banner "CRY BABY" will get questions so you can show why LOL

It starts making boost at 30 percent throttle

I was estimating based off feel.
Once again, why would it make boost under light acceleration?

30 percent throttle isnt exactly heavy throttle. OP Id verify your BBV valve is openiong and closing when you snap the throttle in neutral or park

This is the point I was trying to make.

My 04 has 140000 k. Good find

Off topic but who ported your SC? Any gains?
01-30-2011
Oh I am not complaining I like the whine very much! I was just making sure there was nothing wrong with it as it is a new car to me. I just making sure it is normal. Thanks for the input!

Off topic...
Porting a GenV is a waste of time and money...don't bother.
01-31-2011
I am aware of that, just curious why he wasted his time and money.
01-31-2011
yup the gen V s/c will whine more under light throttle. mines the same way. even more noticable with a cai.
02-01-2011
you guys and your fancy genV's
02-01-2011
I was just making aware...that you were aware...
yeaaa
Anywho...continue.

And thanks for caring blue
