atleast 160 here ..cammed 6.0 456s 6spd....the L i was racing was pegged past 140 on his gauge and i was about truck ahead
I've had my truck in the 190+mph range. I'm pretty sure I've had it right at 200mph if not a little over but ran out of road and had to shut it down. The roads in the hill country are a little rough for those speeds, lol. I know for a fact Allen and I went 188 mph racing a crotch rocket on 410 while tuning... Lol, it was before I had my 200 mph speedo in and was using my gps. It's a fun ride !

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
