I have a Gen 5 3.0 on my Redeye. Was running good but started rattling at idle with 3000 miles on it. I run ATI 10% lower with a 3.750 upper on 93 oct. Swap to a 3.250 on E85. I filled out the form on Whipple's webpage. Tech asked me to send a video with car running at idle. I told tech it sounded like the noise was in the snout area. I asked if Whipple has upgrade bearings for snout and i think i am capable of replacing the snout bearings myself. Tech said it did not sound like snout bearings to him. He advised me to request a return number and send it to Whipple for inspection. The return number did not come with a prepaid shipping label. I pulled blower off at 3500 miles and shipped it ground shipping and $6000 insurance. Cost $245 to ship and took 7 days to travel from FL to Ca. It arrived at Whipple on the 23rd, 2 days before Thanksgiving. On Mon the 28th and Wed the 30th, I sent email asking what they found to the same one that the tech used when asking for a video. I did not get a reply. I called Whipple on Thursday Dec 1st and i was transferred to Mike. After a short hold he came back to the phone. He said case was bad and new case was being powder coated today. Should ship out Mon. Mon my email alerted me that Fed Ex was going to deliver a 75lb package Wed by 8pm. Supercharger was delivered Wed afternoon. My Whipple had very little wear on the rotors. Fixed blower looks like it may be a new one or they recoated the rotors and replaced the case. Whipple covered the 2 day priority return shipping. Sent new gaskets, seals and oil. So i feel that Whipple scores a 10 for quick turnaround time and no hassle warranty. I am hoping the case problem has been redesigned so it does not start rattling again in a few thousand miles when it is out of warranty.
