Subject: Re: Making C4's perform at HPDE by BrianCunningham on 2009/1/23 4:17:35 I asked him to elaborate: [QUOTE]redrose: not saying that... analysis must be made thru "instant center" of the "torque arm" for chassis reactions due to engine torque during accel/decel, not thru "dogbone" IC....note that the C4 "torque arm" is the total of partial engine length+trans+C-beam+diff, and is connected to the chassis on BOTH ends (engine mounts in front, batwing mounts in rear) with engine torque applied "in between". "camber gain", as "weight transfer" causes the rear wheels of an IRS design to move in "jounce", is not normally referred to as "squat", but "should" be considered...again, not a "dogbone" function. "braking" reactions from "brake floaters" (not exactly what these are as "floaters" are free-running on solid rears, but refer to floaters for info search) DO transmit thru the dogbones (circle track racers DO vary the IC of left/right "floater links" to control "set" on corner entry under braking)[/QUOTE] |
