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.
