    how much of an hp increase is need to actual feel it- meaning installing a part then starting the car and noticing while driving around not putting a part onand taking it to the track and notice that your times have dropped .05 seconds because i dont think youd feel that

    That is kind of a tricky question. Do you mean peak hp, or across the board? I would say about 10hp peak. I know when I installed my x-pipe, under 3k rpm the car seemed the same, but above that it started to scream.

    I've seen where people think they felt a gain and when they have it dynoed it was nothing. I think it would be easier to feel low end torque than horsepower

    I'm guessing torque gain plays a role in SOTP feeling as well?

    I've noticed a slight gain when above 2 or 3k after I had magnaflows installed. Then again, that could be all in my head. :shrug:

    Same here....I really felt an considerable hp/torque increase when I installed my LT headers and off-road X-pipe. I did not feel anything when I installed the 70mm TB, CAI and underdrive pulleys all together. I do hope to feel a huge difference next week after installing my KB S/C 9psi kit.

    Some peoples SOTP meters are more fine tuned than others, or their imagination is better....you decide which one

    It depends on if your SOTP dyno is run by your mind or your butt. I have seen several people say that they felt a HUGE difference and they gained nothing or even lost all across the board. Sometimes the desire to get your money's worth takes over.

    I felt the car pull harder about 3500rpms with pulleys
    It felt stronger all the way with the LTs (I already had a High flow midpipe)
    It felt tons stronger with gears
    It feels a little stronger with the blower :D
