9 Second Buick GS Stage1

This was the car's 1st 9 sec. pass. Built around the GS Club Of America's GS Street Eliminator Class rules. A real street car naturally aspirated with a complete Exhaust system,full interior etc. It is the first GS to run in the 9's using the original cast iron Stage1 heads, under the GSE rules! It is a stock stroke 455 with an .038 overbore to give it 464ci. It weighs 3500lbs and it idles smooth enough to still run the power brakes! This pass was 9.98@132.4 mph and was backed up with a 9.99@ 132.7 run.

9 Second Buick GSX Stage2 GS Stage1 9.51 @ 140
We originally built this car with Frank Urbinati back in 1996.It debuted at the GS Nationals where it won the GS Pro Street class races. It was also the 1st GS Pro Street class car to break into the 9's at the time.Thanks to Frank this project came to life. Fast forward to 2010 and the car has been taken over by Bob Ortolani,the car still looks great and Bob decided to bring it up another level. We were happy to have the car come back to our shop and to have the opportunity to work with Bob and put together the new powerplant. The video shows the results of our 1st day out to tune the engine. The 1st two passes were shakedowns to check fuel/oil pressures and get a feel for the new combo. By the 3rd run we had posted a 9.62 @ 138 hitting the 7100rpm rev limiter chip! The 4th run was a 9.52 @ 140. On the 5th run it went 9.51 @ 140.65! After a good cool down and a timing adjustment we were ready to try for a 9.40 run, launching right off idle the car gave us a nice big unexpected wheelie! The wheelie sure lookes cool but we know we can go quicker with a little more suspension work to straighten out the launch and try to keep the front down. We're sure it'll go into the 9.40's yet and maybe even 30's after everything is worked out.
