Nightmare update and New RTI Ramp

RTI Ramp (Ramp Travel Index / RTI)
Today on 5150 Motorsport we to a peak at project Nightmare a 2005 Jeep (LJ) with an 5.3 LS, and then we go pick up a cool RTI ramp and play around with some of 5150 Motorsport Jeeps on the ramp. The ramp is set at 30 degree 65.5” high and 124.5” long. We take Ryan’s 91 Jeep Comanche (MJ) on 37, Dean 98 Jeep Cherokee (XJ) on 37 (IceMan), Patrick 89 Jeep Comanche (MJ) on 35’s, 06 Ford F250 Power Stroke on 37, Ryan’s 2020 Jeep Wrangler (JL) (Rhydo)n on 37’s, and 06 Jeep Wrangler (LJ) (Red Baron) on 40’s and test out the ramp.
The test proceeds as the vehicle attempts to climb the ramp as high as possible with a single front or rear tire without lifting a wheel off the ground. The distance the vehicle can travel up the ramp without losing contact with the ground is measured from the leading edge of the ramp itself to the point on the ramp just below the center of the hub of the wheel on the ramp. The distance is measured up the ramp and, on the ramp, not to the actual hub of the wheel. That number is the divided by the vehicles wheelbase and then multiplied by 1000 to calculate the average. For example, if a vehicle with a 81 inch wheelbase traveled 59 inches up a 20 degree ramp then the RTI would be calculated as: 59 divided by 81 x 1000 = 728 (rounded down). This method of multiplying by the vehicle's wheelbase allows vehicles of different wheelbases to compete on the same ramp.
