    The 10.5@133 pass the boost never went above 10.5 psi (wastegate) and I have scans to prove it. Next pass I went to 14-15 psi and the L26 rod didn't take it.

    The motor is put back together with an L67 now, should be on the dyno late winter/early spring:

    I would rather lose by a mile because I built my own car, than lose by an inch, because someone else built it for me. Your car is your story, so don't let someone else write the book.

    "XPZeed" / Zach's car is legit. It somewhat became my inspiration back in the day when it was just an I/C'd XP GenV car.

    I will also be going to the dyno late winter/early spring followed by the track. I post frequently, so I will have videos/slips later on.

    I do post a little more on CGP maybe due to habit but I mainly browse more over there and here then post like I used to.

    I might have one of the fastest full weight GTP's. Especially on the east coast. PLUS I'm running a stage 2 setup, (heads & cam), stock bottom end and NO SPRAY!!

    My GP weights around 3600 and I should be breaking 10's this spring. Just need to add a fuel pump voltage booster which I'm installing in a couple of weeks. I only clean out my trunk out and take out passenger seat. See my current time in sig. Makes about 530-550 whp.

    I keep my interior because I do car shows and want my GP to look good. Not just be fast or be the fastest. I look to impress people with my GP which I do. It's a great feeling.



    Wouldn't a vehicle have to be running to be the fastest?
    My GTP runs. I use it almost every weekend.


    The fastest cars aren't commonly the most reliable cars.
    I have no issues with mine driving on the street. I don't street race or beat my GP on the street which I'm sure helps.
