I have the LET 181, NW Dual CAI and LET tune in the Aero... I may not be the fastest, but I will be happy to let them prove it at the track....
...now that I have better fueling/AFR's I will see if it is any faster next spring....
(and an LSD installed wont hurt either)
Did I ready something on here or MB that EC was using ASP for their pullies now? Regardless a crank pulley is going to out perform that C3 and you also can contact ASP directly and have any custom size crank pulley made for a reasonable fee.
