Any other Comptech intake owners have a weird resonance at around 3000rpm? I am trying to pinpoint it. So far I've wedged some thick neoprene between the airbox and the strut tower, and replaced the crushed/worn out foam under the lid with more of the thick neoprene. All my bolts are tight. It's not rubbing against the hood liner.

 

you have the new version? If so mine rubbed on the hood prop thingie. I ground it down and I'm good now.

 

I have hood struts so that's not the problem.

I believe I've mostly fixed it by placing the thick neoprene between the airbox and body, and the same stuff under the lid.

I've owned Comptech stuff in the past and I really must say I am disappointed with this item. Fitment is poor, design is odd, and it just doesn't impress me as much as their other stuff has.

 

I think i pinpointed my resonance. I think it's the velocity stack rattling on the inside of the airbox. about the same RPM too.

 

I have the same noise at when at about 75% throttle at 3500 RPM. I'have shaved and shapped my v2 ice box so much it doesnt touch any part of the body. I have the foam all the way around the CF lid, the top of the box doesn't touch anywhere on the hood, and my hood prop is in the trunk. I still get the noise.

I love my CompTech it looks so sexy, and the top end is great.

I just want the strange noises gone.

(I believe it could the the Velocity stack inside the Icebox....but how do I stop it?)
