just curious as to what some of yalls top speeds have been so far...according to hud i hit 140 mph and still had plenty to go.that was fast enough for me and my safety being on i-95 ...outside temp 100 + degrees

got to 155mph in my dads 350z...still felt like it had a ways to go, but the limiter kicked in. I have to say I will never drive that fast again though. Probly won't ever go over 120mph in my current car even though it is also capable of 155

lol did u get the shakes after u let of gas? i did and u still had 15 mph on me

no...it was crazy. It felt the same as if I was going 100mph. That car truely amazes me. I've raced a 2007 mustang GT and beat it by a half car when he got the jump. Have also takin a 90* turn, literally 90* between 40-45mph on the stock supension and tires.

When I did go 155mph I even went through a gradual turn while slowing down....I just coasted and down shifted gradually

137ish completly stock. thats with no 3rd gear too. i was on the way to get it fixed under warrenty

I hit 180 in my old 72 Chevelle. It was pretty scary. All the light poles looked like one big concrete wall. when I slowed to the speed limit, it felt like I could get out and walk faster. Sense then, don't think I've been over 125.

180 in a chevelle!!!??? that must have felt like christifer columbes sailing across the atlantic!!! your insaine man!!

Yea, I was young and stupid. Especially sitting on factory suspension. Wanted to see wher she'd top out at. Won't expecting that. I don't see how people can do it on bikes. I had 4 wheels and all that metal around me and it was still scary as s**t.

I've been a 145 MPH in my car once and slowed down because i was gaining on traffic, could of gone further but I couldn't in the area. Coming back from the 1st Branson meet between Joplin and Tulsa I cruised my car 140 mph for 10 miles or so to catch up to my convoy (got stuck at a toll with no pikepass). Minimal traffic after getting past the toll. Stupid I know, i'd never do it again, I was feeling risky and 90 MPH wasn't enough, Car cruised well and smooth at that speed and didn't break a sweat. If I would of been cought it would of been my ass. It was obviously before the 3.29s and 3,000 stall.

My buddy and I went a 160 MPH in a 1972 Road Runner with a decently modded 400 BB when he was running 3.23 gears. Imagine original 30 year old suspension, and a rattle trap at that speed! Scary as hell but fun too! Glad I got to experiance it, although i'd never be around to do it again. That was when I was 16-17 yrs old.

well i see all the gtps got to where i did...stupid on a public highway yes...some factors on my 140 mph were there were only 2 cars in sight for miles on a straight a way and it was daylight.im still curious as to what a gtp can do if it were tac'd all the way out.160 maybe 170? i know at 140 i still had a good bit to go and this was in 100 degree weather

I think Chris (Toofastgs) took his GTP up to 170 mph one time years ago. I can't remember though. Hope he chimes in. He's the fastest I heard actully tached out He had a cool speedo/tach video too going to 160 mph when he was headed and cammed. Wonder if he still has that, I need to contact him...
