Those were easily the highest numbers the dyno has seen, and I still can’t believe a Buick le sabre put down 450 lol
I sent my friends from the club with that grandpa regal. They were being cautious and had the boost turned waaayyy down. In september, we made 557 SAE on a mustang dyno, pump 93 at 24-25 psi.
They enjoyed the day.
Hey,…don’t tell grandma what we did to her car! :bigthumb:
