i havnt followed it real close but a stripped out 2200lb car and a 1722 (200-210) should probably be capable of running 12's
and if you dont think 2200 is possible in a mk4 your thinking wrong.
with my back seat in and full interior including ac, ps, egr, stereo, spare etc etc was 2700 on the scales...
back seat and spare 2550
ac, ps, washer fluid, egr, cat, muffler 2470?
rest of interior?
glass (lexan)
wheels (rpf1 in 16 saves you probably 50 lbs total.)
aluminum crash bars
airbags
55 convenience feature worth of wiring
battery? who needs more than a 10lb braile at the strip that save you 40lbs there?
the car could probably come down to 2200lbs without much thought which puts you in the low 13s with just the "basic" 200hp setup...
