Vibrations after whipple install on gt350

[1evl_gt350]

So I installed the bmr mounts that came with the whipple kit before I did the whipple install.the mounts were installed by ford when my engine was replaced.never had any vibrations or anything.so after I installed the whipple,since the first start up I noticed a slight vibration coming from behind the instrument panel.and can mostly hear it on idle and when I'm parked or stopped at a light like about or slightly under 1k rpm.i also did notice the front of the car drop alot with the increased weight of the whipple. Anybody else have this issue??

Is it a vibration or a noise?

Little bit of both

There are some apps to detect mechanical vibrations for your phone. I used one when i had a driveline vibe. get one thats not too complicated and run it with and without the blower belt on. Blowers shouldnt add anything but a little noise imho. Made me think back 40yrs when my father in law would put a cup of coffee on the aircleaner.

Are they solid billet mounts? If they are they will create more NVH for sure

My 16 is doing this exact same thing. I pmed you.

Bmr motor mounts use a firm urethane bushing so they are supposed to vibrate more then stock. They’re designed to reduce deflection dramatically.
