Just a update on my car and kit.

So after a few thousand miles running the 70mm SC pulley and the belt having some slap on the lower mount it finally gave out.. I already knew the belt wouldn't last, KW let me know that Gates stated after approving the belt, and testing they came back with not advising using the smaller 70mm pulley. Being a Gates dealer and getting the belts cheap I still went this route. The automatics just need that little more oomph so I wanted a higher boost pressure. I changed the belt and we also did a video on how to change the belt without removing the SC as it seems to be a common myth that this charger has to come off to change belts..

So new belt and all car was running good, it does have some start up issues sometimes, not really sure what it is, but some times it sputters and dies like it's really really rich.. Other times it fires right up. Last week I talked to Joe at KW and he let me know the new pulley kits are out, so I ordered three up.. These are bigger pulleys so not to cause belt problems on the smaller pulley for the high boost setup.. I'm running a 128mm I think and a 85mm instead of the 90mm for even more boost. At 7400 before I was at 12.5 at the ~3k elevation and now I'm at 15.9. We are also going to run up to 8k on the flex fuel running E85.. Finally today my car seemed fast.. I've driven the other 2 kits (C30 and a C38 on high boost) and my car always seemed lacking.. Finally since owning I wished I got the manual.. But the ride home changed all that.. First always spun the tires at the top end, but now second does as well, and it even chirped 2nd.. The car just came alive.. I didn't get on it to much as it's not mapped for the extra couple lbs, but AFR never went above 11.7 so I felt a little safe taking it up until I finally hit redline.. I won't be taking pump gas to 8k as I don't think the engine will handle that.. 15.9lbs. at 7400 so it will be well over 17lbs. at 8k and that's alot to ask of 91 pump..

Just wanted to share my progress, good or bad I don't mind posting up.. Being a dealer for the kit I still don't mind pointing out negatives, but so far the only negative I've had was Church almost/did ruin my motor.. Otherwise no complaints about the kit that I wasn't already warned about..
