@Koa789: Please enlighten me as to how a particular vehicle's trap speed will indicate exactly how the said car will perform from a 40, 60, 100 roll and so forth..? The MK6 gti has pretty significant traction issues even at stage 1 power levels from a dig. Of course you can loosely gauge what a car will do 30-120mph from it's quarter mile trap, but I think power to weight ratio alone is a better indicator of this. One of my best friends has an e90 335i 6MT with the N54 twin-turbo engine. Those cars run anywhere from a 13.3-13.8 factory stock and trap 106ish. Now explain to me this; my car is stage 1 APR on factory tires, I know for a fact that from a dig he'd pull me, but whenever we run from 40 or 50 to 120 it's always that I'm just ahead by half a car. Power to weight ratio tells all, forget about quarter mile trap when considered in conjunction to roll races, there are too many unforeseen factors involved.
1. Trap speed is a good indicator of a car's acceleration over the course of a longer distance.
2. Power to weight ratio plays more of a role from a dig then from a roll. Gearing, power band, and aerodynamics are more of a factor then a power to weight ratio.
3. Your buddy can't drive. A 335 traps higher in the 1/4 then a GTI, makes more power, has a faster time to any speed from any starting speed and has a better power to weight ratio. Even if your power to weight ratio argument was valid, it's invalidated by your own example.
I don't know what else to tell you. A member on here (TSiUG) runs 12.38@112mph, I ran a 12.32@115. Almost identical times, but a 3mph difference in trap speed. If we were to go from a roll, who do you think would win?
