from a dig you will edge him out. He wont have enough road to catch back up.
Roll, he will probably take it. He has a more linear powerband and unlike a 99-04 GT, he actually has power past 5k rpm. Plus 6spd and those GTi's are pretty light.
Dont let these small motors and FWD fool you. the 1.8t and 2.0t are stout performers. My girls 02' Jetta 1.8t surprises even me sometimes, peppy little ****ing car, it spools if you fart in the wrong direction and is insanely torquey (due to the small turbo characteristics of it). I had a neighbor with a 1.8t Beetle, boltons+tune and id say it would easily put my GST away, and if my GST was running more than stock boost on this 14b (put me at 240-250 crank hp) it would still be close.
who cares about track times, especially if theyre running on the street.
It's not so much the times, it's the trap speeds... the OP should be at LEAST 5mph faster in the 1/4 than the GTI.
