I built this car with all attention to quality parts and craftsmanship, and is currently one of the fastest turbobuick.com pump gas/alcohol injection stock block Turbo Buicks in the country. I have owned this car for about 4 years and built it to be a good driver and also perform well at the racetrack. I have gone a best of 9.90 at 137 mph in the quarter mile on 93 octane with progressive alcohol injection. It will run low 10's high 9's with the boost in the low 20's, similar combo's have gone deep 9's and some in the 8's on race gas. Car weighs 3450lbs with me in the driver seat (200lbs). It has been repainted at some point in its life but is still pretty decent - I'd rate it a 6 out of 10. All engine parameters are tunable via laptop, this is a turn key race car or street car and definitely not for the purist. Car is NHRA legal to 10.0 or 135mph with current 6pt roll bar. Everything on this car has been replaced/upgraded since I've owned it- there is over $30,000 listed here in upgrades.
