Anyone else notice a dramatic difference, in acceleration and tire spin, between a full tank and an almost MT tank?
In second gear, I get squirrley putting the pedal down, clutch out, between 3K and 5K RPM, but only with less than a 1/4 tank.
At about 7.6 pounds per gallon, those 14 missing gallons weigh 106 pounds. And that's behind the rear wheels so those pounds are like little levers... if the CG of the tank is two feet behind the axle, does that make a difference? Is it like twice the foot pounds, at that point? Any engineers out there? I would think yes, because if I imagine puting the 200 pounds out on a ten foot lever, I could lift the front of my car every time I hit the gas, therefore I am able to put a lot more force on the rears by putting the weight farther back so 106 pounds of fuel centered 2 feet back (I think it's actually farther back than that) puts the eqivalent of 212 pounds on the back tires. I see why weight placement would be very important in a serious drag racer. 100 pounds, three feet back only adds 100 pounds but would shift 300 pounds onto the back tires for traction and pulling a percentage of that, off the fronts. Seven feet back and they become like "dog pounds".
Did I hear that 100 pounds of weight loss is equal to about 0.1 second in the 1/4 mile? Diet time.
Ah, I'm probably way off on this... weigh off too.
