I haven't dynoed my engine yet, but the compression is even...

I said that it TRYED to pass me... it had a long, long head start to get up to 140kmph, then I fell to 4th gear and went WOT... it got a car length ahead because I had slow response time, then I passed it, and kept going up to 190kmph, when I slowed down because my car started to vibrate... (wheels haven't been balanced yet, methinks)...

It never got farther than one car length ahead.. I've never taken advanced driving school or anything, but I think I'm a decent driver.
