I have a 2008 GT500 running 24lbs boost on a 3.4l whipple. In february it was 2 months old and a shaft broke in it. I sent it off to whipple and they rebuilt it and sent it back. They refused to pay my labor or shipping bill and said they have no idea what went wrong with it. 3 weeks ago it did it again and was twice as bad. it sounded like marbles in my engine. I had put only 1100 miles on the car since last time. So i sent it to whipple. The shop that works on my car said they definitely need to clean out the cooling system and that there was chunks metal everywhere when they removed the whipple. so they sent the pics to whipple for them to see. once again whipple said they dont know what went wrong but this time are going to send me a brand new supercharger and extend my warranty on it for an extra year. thats great! but when i asked for them to pay for my shipping and labor bill for the cleaning, they told me absolutely not. i was told that this came directly from art whipple, however he would never return my calls or emails. Should i let it go or keep pushing? The bill is for almost 1100 and already had to pay it the first time it broke
