Maybe the question is a bit rhetorical. I have a Dinan S3 running 5.5 PSI of boost and I had a 335 turbo with a little bit of work done to it chase me down and we gave it a pretty good run. I should say that I think he is a bit faster than I am (not by much but he started to come from behind me at about 145-150mph, which I found shocking. I wanted to ask the message board how fast these things are, and aside from changing out my pullies to get more boost what could I do to make sure he isn't faster next time? Is there anything that I can do that wont cost me a fortune? I guess I thought it was a bit crazy that a 335 with a $500 dollar chip is faster than an M3 with a $17k super charger. Any suggestions?
