Just put a ported Eaton on my Cobra over the weekend and it is making a gear drive type whine to it at idle and as RPM goes up. Not so much at WOT or cruising speeds on highway. A few of my friends say this is a by-product of it being ported. Any ideas?:eek:

Steigmeier Stage IV. Fresh oil in it also, and only 4500 miles on supercharger.

I don't know if it does or doesn't. I have talked to a few friends who have seen and heard Steigmeier ported Eatons, Apten and homemade port jobs and they say depending on your mods, you can expect to hear more noice from the supercharger other than louder boost. I'm just looking to you guys to reaffirm that and not be so paranoid. My car is running great otherwise. It is just not something I was expecting to hear.

I've heard the Steigmeier ported blowers are louder. I don't think it is an issue if it is a blower whine.

I agree. I seem to have gotten more of a centrifical sound when Leathal Performance ported mine. My KenneBell sounds even more so-Shane
