Why would you be suprised about other cars being fast? 'Busa is fast, and depending on what year it is it might have a governor (sp) on it. I know first series (until '99 or '00 I believe) were the versions without the limiter, hitting just under 220 as a top speed.
I have seen a video of a T-66 Supra eating a GSXR-1000 (newer one) pretty badly. If you can get into 10s with your car it's going to be a very very close race. So don't be suprised about some fast ass car passing you by, it just proves that you can make anything fast longest you pour alot of money into it. I prefer bikes though because they are pertty quick from the factory, after the ZX-10 got released that's the only thing I want now.

You think with 150 crank Hp and almost 3000lbs you will be able to reach 160mph? Are you using KM/h maybe?
I think that you should be honest at least...
