it was maxed out. was reading 6800rpm's when i let off. so i will try to find a calculator. but see it was bouncing off of 160 trying to brake through that. i was there a few seconds so i would say easily 165 it the speedo could register that. scary stuff though. springs did help out tremendously. i will not be doing it for a while. unless its against a 5.0 stang.
