60' times should be generally better on the L27 vs L36, but the 1/8 and on are purely in the L36 hands. That better 60' time to the L27 is purely a function of the lower-down torque delivery (in rpms).
Even with my mods, a stock GTP will start to catch me and run me down starting at about 80mph, on up to his speed limiter (
) where I OWN him up until an unpublished but widely known number in the triple digits.
Pdad and 2000SilverBullet both fell victim to my 60' times last summer, but both ran me down from the 1/8 to 1/4.
