Talk to me about your Superchargers...

Ok, so if you haven't seen my intro thread I have a 2.2 stage 2 ported supercharger, dual pass endplate blah blah blah.

It whines... and I don't mean the supercharger whine it's like this high pitched squeal. I searched youtube and it's hit or miss if the other cars are doing it. Some do it, some dont. Now because its youtube I have no idea what exactly they've done to there cars so I don't know if they are running the same set up as mine.

I'm trying to find the vid of the cars that do it. until then... whats your thoughts?

It needs to be retuned. It's only got the initial tune. It did have a gasket leak on the supercharger but we fixed that. The valve cover seal seems to be fine. If we pour gas onto the intake gasket it's not sucking it in so it should be fine. We RTV'd where one of the sensors bolts in and it hasn't fixed it. The pulleys seem to be ok. The car runs. The A/F are way off but that's from the tune. The guy was waiting on us to report back with what the gasket fixed so now we have to wait till about sunday to get a new tune.

well since every thing is running fine it seems unlikely that a retune is all you need. i mean that could be it but TO ME it just doesnt seem like a tune can change the way your sc sounds. you also said your sc was ported so it cant be something internally. idk im stumped.

Yeea I don't see it being the tune either but you never know. After doing some research it *could* be the alternator. It's coming from the right area and would kinda make sense. It's prolly going HOLY **** with the power increase.

My research brought me to an accord forum where someone had problems with there SC squealing they took it to a mechanic and it was there alternator on the way out. You go to other sites though and people are TRYING to make them whistle at idle :lol: Soooo I dunno. We may take the alternator to get tested or just wait and see if it goes. I really should try and upgrade to a 2.0 alternator anyways so I can get the 6spline pulley.
