I’m going to be installing a standard inlet Gen 4 2.9 Whipple soon on my 04. The car has long tubes and a stock lower pulley. I’m going to a full return system and plan on running E85. What size upper pulley/boost combo are you guys running on stock heads/cam motors? How much much Boost is too much? I thought about running a 3.0 upper, but I thought that may be too much boost for stock heads/cams. I have searched but haven’t found a ton of info on the Gen 4 Blowers. Thanks!
