    How high does a front tire have to be for a standard wheel base blazer to pull off a RTI score of 1000? I don't have a ramp but have access to a forklift. This isn't happening anytime soon, just wondering. Also would lack of drivelines hender the measurement? and would the lack of a motor throw it off too? I know the lack of 500#'s would throw of the figures but by how much? Sorry for all the stupid ?'s. TIA

    Okay I checked 4lo.com and they have a RTI calc. but it shows a 20 degree ramp. isn't the 30 degree more prestegious(sp?)?

    55Willy,

    What's your wheelbase? If you tell me that.....I can give you a bunch of RTI values for a 20 degree....22.5 degree....25 degree and 30 degree ramp!!!

    By the way.....the BIGGEST RTI number will be using a 20-degree ramp......that's just how the math works out.....

    106.5" or close to it. just a standard 77 blazer with a 4" flip. so if the flip moved it any then it's off that much,[​IMG]

    55Willy,

    In that case, for a 20 degree ramp.....you magic number is:

    37" for a 1016 RTI

    Here are some others for the 20 deg ramp and YOUR exact wheelbase:

    24" = 659
    28" = 769
    30" = 824
    32" = 879
    34" = 933
    36" = 988
    38" = 1043
    40" = 1098
    42" = 1153
    44" = 1208
    46" = 1263
    48" = 1318

    Thanks. i found it is 36.41 is the magic 1000. So as soon as I get the body on and the motor sitting in place it's off to the fork lift..use it as an excuss to "find my shock length" LOL

    It's at my old work so I think they would frown upon me taking it to Portland,LOL. The only reason I'm using it there is cus they all thought I was hualing the Willy's to the scrap yard..just my way of saying " Look at me now!!!"
