Whipple rattle? GEN 6 3.0

[Bigmustangguy]

I was checking to see if there is a normal amount of rattle at low rpms when it comes to a whipple?
Im seeing mixed answers online.
Have reached out to whipple and awaiting a response.

In short if you rev it a little bit in park up to 2.5k and then let it idle down, I hear a subtle rattle from what sounds like the blades.
At first I thought it was a rod knock as its a deep rattle.

Have about 2k miles on the whipple.
Stg 1 with warranty.

Anyone advice? Thoughts?

From the Whipple instruction manual:
At idle, you may hear a medium-pitch rattle from the supercharger main housing. This will diminish at about 400-500 rpm above idle.

Would need to hear a video to tell if it's normal or not. My Gen5 gets some bearing rattle at idle if the main blower pulley is not torqued down tight enough.

Knock, knock, knock. Who is it? Whipple.

Trying to get some video today.

They have kind of a sewing machine sound at idle. It can sound a bit like a rattle, or knock as things loosen up. At least my Gen 5 does. The Gen 6 seems extremely similar to the 5.

Almost sounds like clackty lifters.

Is this possibly the chains?

15-2k rpms so far.

Coyotes do not have lifters. They have lash adjusters and cam followers. Also that is not valvetrain noise, it's definitely the blower.

Yep knew it was overhead cams. Was saying sounds like a deep lifter tick or even piston slap.
i sent whipple the video and they said not the charger.

I'll post another video i sent them of the "play" in the shaft but again said it was normal.

Pull the TB off and look at the blower rotors.

Does it sound the same when under load? I can kind of hear the clatter, but not sure what to make of it. I say keep driving it.

I'll have to try under load.

Im guessing yes and only because I've been chasing a vibration at the top of each of the lower gears 1500-1900 rpms and I've completely gone through the suspension several times, drive shaft has been spun at the local driveline shop. Had it on the alignment machine 5-6 times.
Dealer said it was because I lowered it but it had the vibration before I lowered it.

Checked the trans as it kind of feels like a shudder at times, and it will flash between 3-4. found out the trans was 1.5 qts low.. good times.

I noticed the noise when I was in park and running it up to 1500 to heat the trans.(Trans has to be checked at min 205 I believe).

Also noticed the engine vibration on the armrest got pretty bad.
