    Lingenfelter is off

    Well I couldn't stand the whistle anymore. It was too much today. So I just ripped the Lingenfelter CAI out of the car. I'm back to stock minus the snorkel.

    A couple of days ago I tried taping things, moving things, rotating things. The whistle never went away. I have no idea where it was coming from. I want to put it back in, but I'll have to figure something out.

    That is weird, I really don't hear any with my car. Maybe real faint if I am really trying to hear it, but not really at all..
    Good luck trying to figure it out, hope you get it back on soon..

    Windows up, I couldn't hear it. Windows down I heard it. Only way to not hear it with the windows down was at idle and WOT. I like WOT, but most of the time it's not appropriate

    I just took a look. It could go down tighter and not mess with the hood/fender lines. I didn't think to look at that, the hood liner has a pretty good indentation from being pressed on. Maybe it needs a little more pressure. It's a pretty quick switch I might try it again this weekend.

    Thats why I hate those kits. Its a cheap way to make a CAIK yet the price is a joke IMO. Exactly why I cant wait for the Volant.

    Re: Lingenfelter is off

    I haven't had ANY problems with mine...does the whistle sound anything like the whistle you get from a throttle body spacer? maybe there is a bur on one of the parts that needs to be deburred. I've heard if the air is coming in at a high enough force, a small bur could cause a whistle.

    Since I'm still using the stock tube the only parts of the Lingenfelter are the attachment to the K&N and the K&N itself.

    yah...you got me. I look forward to hearing if tightening down your hood solves the problem. I hope it does.

    I have the More box with the oval K&N Filter(RF-1034 I believe) and I absolutely do not hear any drone whatsoever. From the pictures ive seen it looks like the More box seals better than the LPE. Both boxes are VERY similar so I highly doubt that there is very much difference if any at all in performance.

    Well...I do know it isn't the MAF screen causing the whistle.

    Have you tried turning the filter? Seems the people that have them horizontal don't have a whistle. At an angle, the "top" of the filter is near the hood liner and could be a whistle area.

    What you don't like your car sucking air. I think it sounds good. I have the more performance CAI and a bbk 80mm throttle body. Some think i got a supercharger with the sound it makes.

    I'd be fine with a sucking sound. My Silvy SS had a sucking sound with the Volant kit it had. Before I got an intake box on my GTO it had a really loud sucking sound; that was fine also. The V has a whistle. Very high pitched, well whistle. You'd think a bearing went out or the belt was completely shot. It's not cool.

    By the time the whistle gets loud enough in my car the maggie whine drowns it out.

    Better that then a siren behind me!

    I have a slight whistle only at part throttle. Like 2k rpm area. You have to be listening for it to hear it.
    I rarely drive this beast at part throttle, so, problem solved!
