    Hp numbers are meaningless and should only be used to quantify power gains from mods. Track times are what matters in the end.

    That's what I'm using it for........ To get real gain numbers from members who have Ben doing this for awhile........ Not what the box claims or the salesman says

    If you are using it to get an idea of track times.. can you drive?

    Cause.. you can give me all the mods and hook up you want...I still can't drive to save my life.
    I drink..so consider that when reading my posts.

    I think next on my list is going to be the intercooler. It seems to be the most expensive part of my build but has nice gains

    i got a bit more in mods, but the difference between having kr and no kr seems like a 50 hp gain since i got rid of all my kr.

    If you're planning on a dyno day, run a gallon of 103 in it...just incase.

    I'll venture to say if it's knock free and mechanically sound it should do 235~WHP or so.
