The car is a 1999 Buick Regal GSX. Its a little project car my grandpa and I work on together. Before I modded it a little bit, just basic bolt ons and it hit 13.2 in the 1/4 mile, stock supercharger and everything just minor bolt ons. I made a mistake by taking it too the track with high boost (on race gas) and was too tired too swap the pulley when I was on my way home (long drive home from the track and it was dark at the track). I forgot all about it and then my grandpa was driving it (on pump gas now, still with the high boost pulley) and got on it trying to mess with an M3 and it didnt like high boost and pump gas so it popped a few pistons. We said fuck it and went all out on the rebuild. Specs on the motor: 231ci Bored, Balanced and Blueprinted. All Forged and coated Internals internals, with 8.0:1 Compression.
