The guy who helps me with tuning and dyno services has a buick regal that is a salt car. He has been 212 at maxton and right at 300 on the salt. He is building a long fiberglass thing to take to the salt that has his all aluminum splayed head small chevy and a 114mm precision turbo. I beleive he said it should go over 300 not sure of the class? He keeps trying to get me to go to bonneville with him. I have been to Maxton alot but it was only 1 hr. drive from the house.
