So it seems the "tweaked intakes" are worth the cost as per the returns I have seen in this thread. Do most of you also have the ported lower "Y" pipe also? Seems that item should indeed be paired with the intakes. From what i read it seems the peak numbers are between 10-15HP and torque at the wheels, nice. If the "Y" adds a bit a gain of 15/15 could be possible and the longer across the rpm range we see the gains the better. I'm glad I found something that had a decent return for the dollar.
I am still trying to source the 70mm SC pulley I want to run with the NW 178mm/PSK without sending the stock pulley to be turned in "Bulgaria".
