A brief history of Winston's beast:
It was bought as a 2006 model in August of 2007 with 12,000 miles on it. At 14K miles I took it down to KRC for the beginning of the turbo build. The initial dyno sessions were intense, probably in the range of 70-100 dynopulls at WOT, slowly upping the boost. The truck put down 651whp on a forged 6.1L block with 8:1 compression. After that I drove the truck for about 2 weeks on the street to test out how the one-off kit worked. Probably 20 or so WOT runs on 8-10psi is where she stayed.
Winston's symptoms:
The only symptoms I began to notice... a hesitation between 3-4 shift, and at the very end when you'd try to launch it would slip BAD off the line, then at 3500rpm it would engage and throw you back in your seat and shift just fine under boost. Amazing this thing held up as long as it did.
The High Torque Capacity NAG1 that I hand delivered to KRC (Marty's shop) will take care of the problems Winston encountered.
You can see why I designed high performance Kevlar clutches for our NAG1's.
The clutches were worn between 60% and 99%.
K3 clutches in the photo were worn 99% and the cause of the long 3-4 shift.
You can see by the color of the steel pressure plate how much heat was in the transmission due to the slippage.
The photos are of the K3 clutch (new one on the right) and the K3 pressure plate.
