Been 150mph, I chickened out and didn't go any faster, plus I was running out of road. Same setup I have now minus the Alky and Race tranny so I was still running 2.93s. The car still had plenty in it so i'm sure 150 wouldn't be much of a problem again.
I've cruised at 135 mph before for several miles... I was catching up to a group. They had my front door if you know what I mean.... all of this happened in Mexico too.
