    1/8 mile run how accurate to 1/4

    Ran my 2006 Sts on the 1/8 mile and got a 9.34. I looked at web sites it says would do 14.58 in the 1/4 how accurate is this.

    what was your 60' and what was your mph? usuallly if you don't spin much its pretty accurate. But in a truck I would subtract a .1 just due to areodynamics that plays affect. for cars its more accurate.

    example...I have rane my truck twice in the 1/4

    8.9 1/8 mile, converts to 13.9, but I ran a 14.0

    went back after a few mods, ran a

    8.57 1/8 mile, converts to 13.3, but I ran a 13.4.

    Its usually pretty close, ran a 7.50 1/8th converts to an 11.6 1/4 i ran an 11.8 with notrous problems, so it woulda probably been dead on, its not exact but can give you a good guestimate.

    I ran 9.87 @ 73 MPH 1/8mi & 15.21 @ 90MPH With a 2.3 60' The conversion chart shows 9.85 to convert to 15.37 Now the track prep was horrible and I couldn't hook up to save my life.

    Well didn't give slips out so 60' and trap speed don't know. Hooked really good after burn out. First run of night got a 9.56 so after hooking lowered time. Ran good for a 4.6 all stock. Truck in different state in storage need to time that.
