No offense to anyone, but the more I look at the offset SC placement and secondary belt and the giant mounting bracket included in the KW kit the more I see it as a big over-complication for two seemingly non-existent issues (intake air temps and belt slip). IATs will be lower than stock with both kits since they are intercooled with blow-through MAF, and JR kit testers haven't had any belt slip issues on and off track. It also has me wondering if JR did more track testing than KW and as a result, JR made the conscious decision to keep their kit simple. They are both well executed kits in their own way.
All things considered, what I'm seeing is that the two kits aren't very different when it boils down to the performance increases over stock at 9 psi.
I'm still very undecided between the two kits as a personal choice should I ever go FI.
