Recently placed my order for a Whipple 2.3l 140ax from Stillen Performance and I can't wait for it to get here! I have been wanting to install a supercharger since I bought my truck and have been saving since I bought it to do the same. I attempted to do my homework on choosing a supercharger setup for my SSS and decided on Whipple. Seems like it all comes down to what you want to spend on a setup and what brand/type of supercharger your prefer for your build.
I am curious as to how much boost my stock LQ9 will SAFELY take. The 140ax comes with a 3.625in pulley that is rated for 6-8lbs of boost. I have a high-flow exhaust (long tube headers, no cats, Billy Boat exhaust) so I know that will factor into losing 1-2lbs of boost off the top. From those who have supercharged the stock LQ9 before me, what is my max target boost before I run into driveability issues? Thanks in advance as I am looking to add a smaller pulley at the time of install since I am tuning via BlackBear Autocal.
