Ive hit 172 in my 85, to go that fast you definitly need lots of open space, I did it at around 3am.
Dude with the front runners, if youre going to go 100+ Id get rid of those skinny little POS front runners, they're meant to go fast in a straight line only, theyre skinny to reduce rolling resistance (drag). If your car is setup for drag racing, I definitly wouldnt try openin er up on the E-way, drag cars cant turn quickly, which sometimes you need to do on the road. So front runners + drag suspension = inevitably crashing, possibly killing yourself and/or trashing your car. Drag suspension WAY to soft for haulin *** on the highway.
BTW, the faster I went the more stable my car felt. My car sits super low (my h-pipe is about an inch off the ground), I have z-unlimited tires ( very important if you plan on exceeding 129 mph). My car rides like a brick, has super tight suspension, hardly any weight transfer at all, perfect for corners and high speeds.
And before any of you call bs, according to a gear calculator, theoretically I was going 203 .

You know factory tach's are **** im assuming (based on the )

As far as a fox hitting those speeds, you are lucky you have a dropped car. My 5.0 (suspension is set up STOCK, with chassis stiffening out the ***) is floaty as hell over 115. Or maybe im just used to the TA, either way, im scared to do over 120.
I got a 5" autometer monster tach with a shift light .

And XBA 4k in 5th with a 2.73 is freakin movin. Id guesstimate it at around 160+, considering windresistance ride height, etc.

1 part is your suspension, but I bet the "floaty" feeling youre gettin is from your tires. I ran 2 sets of Goodyears (hated em both), 1 set were the Gatorbacks, great dry weather tire, horrible for everything else. The other were GSC's (corvette OE equipment), the GSC's were even worse, the sidewalls were SUPER flimsy even with 44psi in em, @ around 125 the *** end would shimmy side to side really bad. I thought something was wrong with my car, I got caught in a freak snow storm and managed to burn em off in less than 1 hour tryin to get back to the house which was 2miles away. Anyway, I got Dunlops Sp8000's (225/40/16 - theyre discontinued) immediatly my shimmy was gone. Then I could go as fast as the car would let me , VERY stable. Like I said before TIRES are VERY important at those speeds.

Yea, my stock 93 GT looses power after about 110-115 but I can slowly work my way up to 125.. I think the highest I hit was somewhere between 125-130

I like the interstates personally . Late at night, there MIGHT be a car every couple of miles.

BLue and Futball, its your gear thats killin you guys. With that steep of a gear, Im not suprised you guys can barely reach 130. 302's are torque motors, let em do some.....torquing. [8D]

Im too scared of going fast on highways, etc. Just because of cops... I just simply cannot afford another ticket. So I go hard on my car out near the farms, etc. late at night where theres just thousand of animals to jump in front of my car and I can try and swerve to avoid hitting them at 130 [&:] Sounds better hugh lol
