I remember when i thought setup and mods equaled performance. Then, at the last shasta event, i got my ass handed to me by a STOCK 510 on good tires. Not to mention, this 510 had moss growing on it... Dude knew how to drive....
I have also rode along with some friends on Thunderhill. 190HP KA24E/twm induction. Built by rebello in a VERY sorted 510. Add a great driver, and we were routinely passing cars with over 200 more HP.
Skills bro.
