has anyone ported their stock eaton blower? i was thinking about doing this. i will eventually swap it out for a 2.2 kb blower. i just don't want do that until i have a few more miles on the car. i have heard about guys gaining somewhere between 30-35 rwhp by porting the stock blower. i have already put the 2.8 pulley on, i just want the most bang for the buck. any feedback would be great. thanks.
