I wanted to share a little about my KW set up
At this time I run a KW C38 on the high boost pulley setup, My car on a delicious tune that has not been finished yet and I put 417hp to the hub. I would not change it for any other kit, I'm 100% happy with my kit. For me the separate drive system is one of the biggest factors in it. But there are others, I like the adjust-ability the kit gives, the piping layout among other things. KW customer service has been outstanding, and not just because I work at Fteightysix. Personally they have helped me out on many levels and I have seen KW step up to the plate above and beyond expectations.
In reference to a post above about durability of the C30 on a daily and a track car.
We have several local customers running high boost pulley set up and E85 with 60 plus mile daily commutes..
With that said I do not know of a KW kit on any car that see's the track on a regular basis like the CSG car does. I do know a KW car does track but im not sure if its weekly/bi-monthly like the CSG car. My post above was simply stating that this engine boosted by a C30 (regardless of the kit, its the same blower) Has ran many many track days with no engine issues. Because they track the car so much he has extensive knowledge of what mods work and what doesn't. I'm in no way saying that a JR kit is better or worse, just sharing my knowledge that our cars will hold up using the same blower can handle the FI & track time with a proper tune.
One thing about me and anyone here at Fteightysix - Since we are owners of the same car we give our honest feedback about product and will always tell ya'll the honest truth and if we dont know or think someone else has first hand knowledge even if it is another shop we will tell you or refer you to them. See our post in our review thread about how we run our business.
