Being a good Texas boy, I've had my share of Pickups, Corvettes and Trans Ams, but as the time went on I've migrated to a bit more specialized vehicles...
My Daily Driver... A 2006 Freightliner M2 with DD13 (12.7Liter) and an Allison 6-Speed:
And with the trailer for hauling toys around:
Lotus Evora. Bought this when my Son was 15. It's pretty much his at this point. It was factory supercharged... But now is on it's 2nd engine, turbo charged and running a Megasquirt ECU. Makes about 550hp on E85. Bit less on pump gas. We've raced it on occasion.
Race car #1:
Race car #2:
We run both Sprint Cars winged and non-winged. They have "Racesaver 305" engines. 305cid Chevy V8s with Spec Brodix heads, flat-top pistons and other items to keep the cost down. But they are methanol fueled, mechanical fuel injection. They "only" produce 440-500hp, but then only weigh 1500lbs with driver, so pretty good power to weight ratio. These are an experience to drive - imagine - no flywheel, no clutch, no transmission, a U-joint bolted to the back of the engine (and right between your feet!), enough stagger that it's a handful getting it down the straight and enough power to stand the car on the rear bumper if you can find the traction.
Superlight Coupe:
I originally built this car with plans for it to be a high-end street car. Somewhere along the way it's turned into a race car. It has had an LS7 and and LS1 (both blew while running the Big Bend Open Road Race). Now has a Turbocharged Lexus/Toyota 4L V8. Modeling software says it's good for 1050hp, but I've never cranked up the boost. Currently the motor is out for a dry-sump conversion. Trans-axle is a Graziano (think Audi R8 and Lambo Gallardo).
Also have a bright Yellow Ford F250. 15 years old, 4x4, Diesel, HMMWV (Humvee) wheels/tires. All the kids learned to drive in it. One of the kids slammed it into the concrete wall on I635 (loop around Dallas), but we patched it back together. Has about 250,000 miles on it now and still going.
