This is a video I took of a race between a GSX, VW Mk2 1.8t, and a SRT-4. The guy in the GSX was talking all this trash to my friend with the VW, so we hit up the highway and let the cars do the talking.
The 1.8t is fully built, including all internals, and has a custom-made Exhaust and Intercooler piping with a big turbo (cant remember what type at the moment - will update this when I remember) running at only 10lbs of Boost. It should also be noted that the Mk2 was not running at full Boost and was rev limited to only 6500rpm. Also, the entire interior was stripped out and weighs in at just above 2000 lbs. The engine is capable of hitting 9000rpm easily and is expected to be running 25+ pounds of Boost by the end of the summer. My friend estimates that he is putting down 350whp at the current settings, but should hit closer to 500 or 600 once running at full Boost and revs.
