After the install of my C&L upper plenum and BBK 75mm TB, Im hearing a sucking noise from the right side of my car but it only makes this noise under load. Launching from 1st to 2nd and so on I hear it

I first noticed this after the install of my BBK Cold Air Intake a few months ago but it was barly noticable, but now with the increased air flow it's much more noticable. I have checked all the hoses and everything is hooked up correctly and nothing is loose or plugged. I talked with one friend he it's probably just air being sucked through the intake at a higher volume.

There is no performance loose either, the cars run GREAT and huge performance increase. The car idles fine no stalling or hesitation on launch.

any ideas..??

Thanks Matt

 

This is normal as you have an open element filter. I just added a Voliant intake to my Hemi and it sounds like an exhaust from 2500rpm and up. Part of the reason all stock intakes are restictive is to cut down on noise.

 

I noticed the same thing soon as I put my BBK fenderwell kit on. As Venom said, its totally normal.

 

its normal....I to just added a 70MM Accufac TB and accufab plenum and the sucking noise became even more noticable!!!! I LOVE IT!!!!!!!!!
