so I went to the drag strip saturday, my set up is pretty basic, junkyard motor/turbo extra boost and fuel, 2.5" crush bent exhaust,
previously I had run a 13.010 @ 107.75 with drag radials about 24" diameter on a 1.9 60' at 9 psi,
since then I added megasquirtnspark, FMIC, DSM injectors and upped it to 15 psi on some 26" drag slicks, this time my best was a 12.814 @ 106.64 with a 1.7 60',
I understand the tires giving the better hook and 60' and the I/C and piping causing a bit more lag on the bottom end but the topend is quite a bit stronger and the drop in trap speed just baffels me I'd think the larger lighter tired would yield a better trap speed, any of you hardcore drag racers got some insight?
