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.
Ames, how far down is your hood adjustment? can you go any tighter?
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.
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.
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.
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.
