    What part of "You are not doing 130 mph at 5K rpm even in 5th gear - physical max is 119.3" do you not understand? You claimed 130 at 5000 rpm - which is not physically a possibility. 5500 rpm is the minimum physical engine speed to reach 130 mph vehicle speed - and that is not calculating for road resistance, wind resistance, and coefficient of drag.

    I am not saying that your car cannot do 130mph, just that it is not doing it at only 5K rpm, as you stated earlier.

    Holy shit is it that important to prove your car can go to a lousy 130mph? My mother's Accord will do that and get there quicker than your car.

    Obviously not as important as it is to him to prove I wasn't doing 130 at 5k... I just type a few words and post a link, he's typing out term papers with allegorical calculations.

    Well when you grow up those allegorical calculations won't seem so difficult, probably once you get out of the 7th grade.

    Nope, still not with a 205 - you only raise it from 119 to 122. That is not 130. Have to go taller.

    You did something wrong, at 5k I got 129.

    Nope, I have a program here especially for it, and a second program to double check it. I actually graph out all of the gears.
    You need a 235 in a 70-14 to make 130 - without calculating for road and air resistance, or CoD.

    Now a 205/75-15 would do it, or a 225/75-14.

    Like I said earlier, I'm not saying that you can't hit 130 in the car, just need a few more revs with stock tire size, and stock rear and transmission.

    BTW - You can download one of the simple spreadsheets from Dave Lum at www.datsuns.com
    You should see that site anyway - good stuff.
