Here are a few of the pics I grabbed from the Challenge. Sorry, these are all raw/unedited. These pics represent just a small sample of the cars there, and there is much more cool stuff in the gallery links at bottom.
500 hp VW. Has a semi radical small block Chevy 350 under the hood and a big NOS bottle in the back.
Vorshlag's LS1 swapped widebody E30, the overall winner
Toyota pickup. Nothing under the hood except for a hamster wheel, and no I'm not kidding. In the bed is this supercharged GM 3800 drivetrain out of a Riviera.
It looks like your ordinary, run of the mill widebody BMW 2002. But really it's kind of more like a 2002 shell over E30 subframes and suspension. Not to mention the turbocharged M20 stuffed under the hood. It's also a brand new build that the builders intentionally "distressed" to make it look like an old race car. It came out really well.
This Fast Butt Ugly Starion (nicknamed "Uranus") is driven by a clown
Wreck Racing's supercharged 1UZ V8 Miata (with NOS). No windshield on the car, which was totally against the arbitrarily enforced rules. I don't think it had headlights either, also in violation.
LT1 Firebird that also has NOS, and the best rattle can paint job on earth
Engine swapped Honda N600 that came all the way from Washington State. Has a Honda D16 engine swap in the back. You have to see this car to believe it. His build thread is here (and there are lots more pics in my gallery)
Porsche guys came out to play with us on Saturday, but unfortunately it rained.
Me in my $930 Miata. Stock suspension fail.
Pro driver George seemed to like my crap can Miata. Wish I had a larger version of this one
