Grand National and GNX History (part 2 of 3)
Buick quietly re-entered the supercar wars in the late eighties with a turbocharged 3.8 liter V6 engine in an all
black Regal. The car was so outrageously fast that its now among the most
collectible cars of all time.
Grand National at the first "Pinks All Out"
LSPBC member John N. and Houstonite Ryan M. makes us proud at "Pinks All
Out" episode 1. This video has been edited to show only the runs related
to the two Buick entrants.
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.

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.
