145-150 in a 6 speed 1996 firebird formula BBK 1 5/8" headers SLP cold air induction, throttle body foil, SLP exhaust, Hypertech programmer US HWY 67 between Farmington and Fredericktown.  

Topped 145mph for a good stretch of 217 outside of Portland OR, at 1030 at night.

'66 Mustang, 306 (at the time) flat hyd. cam, 650 holley, headers, and all the other basics. TKO conversion with the .68 5th gear, 3.00 peg-leg diff in the back.

The dynamics of a highly antiquated front suspension wearing 40 year old 6 cyl. springs and $25 el cheapo shocks gets quite entertaining at 140+. I doubt my front tires spent much time in full contact with the road.  

'bout 100ish in my vic 105 in my pathfinder. 135 to 140ish in my imp and about the same in my camaro.Not as high as some but I'm proud of them.  

170mph in 3rd gear... clicked it into forth.. checked the speedo and about crapped my pants... decided I wanted nothing to do with 5th gear on the street...  Took it to Maxton the next weekend and ran 200.758mph in a mile.. Car ran 256 though the mile at Bonneville.

In my old 91 Trans Am with the stock L98 i showed about 145ish on the I-5 by Custer Washington. In a 2001 Cadillac Seville STS i bounced it off the governer at 155 after racing a 96 mustang gt (and winning), i just continued on accelerating to see what it would do. Those kinds of speeds are pretty gnarly on county roads.    

Around 150 on Pa turnpike in a 76 Trans Am I ased to own speedometer went to 140 it was bask around to zero.The rear end got a little loose so I lifted.  

this is why i want to enter things like the silver state classic. there's alot of open road races, i want to be in. where it's legal to go fast. )
keep it safe.

160mph.  

Fastest I've gone was 125ish on the freeway before the governor kicked in and shut off the car  

i figure 150 or so in my '05 Mustang on the EOE in Schaumburg well after midnight on a weekday, racing a hopped up vette. pegged the speedo for a good minute and a half at least, and it was pulling strong and was pretty stable untill we caught up with the only other guy on the road. the second i lifted and the vette blew by me like i was sitting still. almost got busted on 290 south of woodfield one night against a hot Cobalt SS, he got a little ahead of me when we got to 100, we got up to at least 130 (too scared to look down at the speedo)and was slightly behind him when we blew past a state trooper. i saw him and let off, but stayed in the lefthand lane. he pulled out and followed me for a good minute, while i'm quite literally sweating and praying. then he peels off and grabs the cobalt. that was a pretty big wakeup and now i try to behave a little better  

i hit 130 on i 94 from fargo pretty easy in my grand prix GXP last spring
