Looks nuts Trent!:thumb:
You think it would gain any if the charge pipe between the two turbos was bigger since you have the race cover now??
not really , the inducer of the S475 is 2.8" , the outlet of the PBK is 3" ID 3.5" OD so really the pipe is already bigger than the inducer of the top turbo and the exducer of the secondary , if it was sucking ya it would help , but being forced it shouldn't matter due to the final restriction being the inducer of the top turbo .
