87 Turbo Buick 11.42/121mph pass
June 26, 2009 - Baseline testing for the next upgrade. Funny part is Mustang before me forgets to
close his hood. Not so funny as my tires cool down waiting for him to get
his act together. That rattling noise after launch is a lesson learned on
how much the tranny actually moves under load and how much clearance to
maintain from rotating parts...oops.

Here is link/history for my original 87 Buick Grand National - GARAGE QUEEN
Grand National passes Corvette as it wrecks
John N. testing his tricked out Stage 2 Grand National at Thunder Valley
Raceway park. His opponent in a Corvette stays in it too long and narrowly
misses hitting the GN as it passes by! The GN's build up had recently been
completed and this was intended to be a soft pass with only 20# of Boost. The camera person was there to film
the car's reaction to the launch for tuning purposes. They were so focused
on the GN that they did not notice what was happening to the Corvette until
it was over.

guys from turboBuick.com and learns
about the one-time "fastest car in America," the Buick Grand National.
Buick - 1985 Buick Grand National
Here's another great video from the History Channel's archive on the 1985
Buick Regal turbocharged Grand National.
Per the History Channel's exact video description:
attention-grabbing celebration of speed, the 1985 Grand National represents
Buick's return to muscle-car roots. Now, two teams of veteran mechanics try
to extract everything they can from the Grand National's made-for-speed
equipment (including turbo engines, fuel
injectors, and racing transmissions) to transform the car into a big, mean
The premise is simple: FULL THROTTLE selects two teams who are each given
the same model of classic car in a similar state of disrepair. They're
supplied with a garage, tools, and parts, and after 20 hours of repair
time, they battle it out in an old-fashioned drag-race on a certified
track. The winner keeps both cars. The loser keeps nothing.
They're fast, they're flashy, they reignited America's love of muscle
cars-and finally, the 1985 BUICK GRAND NATIONAL returns with a vengeance on
87' Buick Grand National on the hunt!!

1966 Buick Convertible Barn Find Rescue, Part 1
This is the story of a '66 Buick Special convertible that had been
abandoned in Arizona in 1978 by the family of Rick Pewe, editor of 4-Wheel
& Off-Road magazine. In 2011, the guys from HOT ROD Magazine, in
conjunction with Rick, spent four days bringing the car back from the dead
with plans to drive it home from Phoenix to Los Angeles. This is part 1,
with the hacking fun the guys had rescuing the car. Look for part two,
loaded with road-trip hilarity. The story is printed in the September 2011
issue of HOT ROD Magazine.
