Modded 1.8T
I know of an older gen Golf (sorry, I'm quite ignorant about VWs) with a modded 1.8t, T3/T4 hybrid, huge FMIC, etc... who did a highway run against my buddy Talon. The Talon runs 12.70 on pump gas and 12.50 on race gas.
Though the DSMs are not at their best on the highway, his car is no slouch. From 120 to 265, they were dead even with the Golf *gaining* a few feet passed 240...
I have never seen that Golf on the strip though, but with slicks, I think it could go high 12s. It was build at RMR. The owner calls himself JaysTurbo.
