In the performance section we are still trying to figure out the size of the Cooper S turbo... however we've made some headway on sizing the JCW turbo. For reference; I've attached the compressor map courtesy from Umsports and BorgWarner of the stock Factory JCW turbocharger compressor!
Please note; the compressor is more efficient and higher flowing than a stock K03 or K04.
I was just looking at the part numbers for the JCW and S turbos and they are different. What is strange to me is that they both have the same price-$2,118.00.
