Tuning the Turbo GMC Jimmy!

A few weeks back I visited my good friend Gary Hart to attend the Street Rod Nationals in Springfield, MO. I took random videos of us at the event, and driving/tuning Gary's super cool 1950 GMC truck - with a turbocharged, electronic fuel injected, 1950's era 302 cubic inch six cylinder. As you can see, she runs like a champ! and makes decent power at 10psi!

Firing up the Turbo Jimmy GMC
This is Gary Hart's newest project: a daily drive-capable 1951 GMC pickup with a 311" Jimmy inline 6 engine, HX30 turbocharger, large air-air Intercooler, distributorless ignition using 6 LS coilpacks and Ford 36-1crank trigger, with a Megasquirt-2x (Extra) EFI system from www.DIYautotune.com. Originally built for racing at Bonneville, the engine still has a race-oriented cam profile which may get swapped for something more tame later on. Or maybe not :-) Truck has a TH400 trans, 2.73:1 rear gears. This is a video of an early startup, there are still some bugs to be worked out before we do much tuning. Stay tuned for other vids in a few weeks!
