The rattle in your video is similar to what I experienced with the same blower.
Thanks,

I sent a video off to whipple & they told me this is normal at idle even after breaking in. They did advise me to make sure it doesn’t rattle while driving after its broken in past 1500 miles. I’m don’t have that many miles on it yet.
Stock blower did nothing but heat soak right away, didn't cool down the iat2 much at all because of the small intercooler bricks and when it was overspun with a pulley it quickly ran out of steam in the upper rpm's on highway pulls.
yeah, I sold my factory blower and put the whipple on. its night and day with the cooling benefits. arguably any blower upgrade would be better than the heat issues with stock. just depends on your preference for type / model / usage case.
I wish I had a PD blower. The centrifigal blower starts about 3500. It doesn't do any good on the low end. I never drive in the 3500 rpm range. grrr
No offense, thats why I upgraded to a whipple / PD blower over a pro charger. my local shop kept pushing me for a pd blower. In all fairness a pro charger would probably give me more traction, but thats not how I use the car. I don't drag race it. its used for spirited street driving or back hills and curves. Im happy with the way I went even though I don't have it turned up to 4 digit whp numbers.
I just bought a 2014 Z51. It has a centrifigal blower on it. I'm not really happy with it. I don't like the sound it makes, and like the the guy above said, I never drive in the 3500 rpm range either. I would love to swap it out for a whipple or something, but ,damn, they are so expensive!
