This is my daily driver 1987 Buick Regal T. 3.8L turbocharged, white version of a Grand National. Stock block with ported Champion iron heads, slightly modified turbo, injectors and downpipe. Running on 93 octane pump gas at the track, this 10.99 was backed up by 5 more 10 second runs with a best of 10.81 @ 124 MPH. Yes it has A/C and gets 22 MPG on the highway. Leave it up to a Buick !
Tom's Turbo Garage: Buick Grand National Street & Strip Upgrades - Part 3
In this episode, we focus on making some good old turbocharged horsepower on my 1987 Buick
Grand National. We also take a trip back to 1987 to look at performance
recipes back then.
This is part of a multi-part series where we're making a host of
modifications to this classic American muscle car to improve its
performance on the street and strip. Thank you for watching and

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.
1986 Buick Grand National Turbo
My Buick Grand National running 12s with just a few things done to it.
During these days, had the stock turbo
running 20psi, completely stock engine, just had put alcohol injection on
it, stock torque converter....it ran pretty good for what was done to it.
Now it is a complete different animal!
