top speed?

many years ago being dumb (children don’t try this at home) with my 87 sport coupe 50SO all stock and digital dash that only when to 85 but if you switched it to KPH it went to 200 I got my car up to 185 KPH. Figure out the math. For the record as dumb as that was it was very late at night and I was the only car on the freeway.
Oyea the car would only do it in drive if I remember right every time the car went into overdrive it would slow down till I put it back in D.

Had that car for a long time god bless it drove it till 245,XXX miles then endured it man that was stupid that car had full power everything on the list and it all worked. But it started my love for fox birds.

Wouldn't the SO's power band drop off somewhere around 100-110mph? I'm guessing it can maybe make 120 before it can't suck enough air in to keep going. In Drive, wouldn't it be going around 105-110mph at 3500rpms with stock gearing and tires?

185kph=115mph

I've had mine up to around 135. :) (I burried the speedo and climbed a few notches on the tach) Those were controlled conditions too. Two hands on the wheel and one foot on the floor. :hick:

My brain is telling me that some where I read or somehting that top speed of the turbo coupes is 149MPH.  I guess is doesn't matter as long as we beat the other guy.

I had both my '88 Cougar LS and '87 T-Bird Sport indicating 199 km/hr (about 120 MPH) on the digital dashes. I've never had the '88 T-Bird near that fast - age has put some sense into me...

The Cougar was actually still accelerating when the speedo was indicating 199 - I remember slowly but steadily pulling away from my sister's ex in his '84 Cutlass. He was so mad that I'd beat him that he pulled his 305 and dropped a 350 in. By this time I had the '87 Sport, which explains the 199 achievement in that. I beat him again, BTW...

For the sake of honesty I should also point out that both speeds were achieved on a long, straight (about 2 miles) steep hill on a 4-laner known as the "Magazine Hill". Yes, I was going down, not up :hick:

Seek has it pegged for the Asthmatic SO 5.0...

May get a little more out of one easing off the throttle and letting it shift to O/D... But then the HP may be so low it can't overcome the air drag...

i can tell you that my ranger, back when it was stock save for more boost, got clocked by a state trooper at 146mph.  that was years ago, and i've grown up.  the fastest that i've gone since then is 140 in my wifes old cobalt ss/sc.:D

Ok time to let the cat out of the bag. I plan on competing in "The Texas Mile". Its a standing mile run for top speed records. You go from 0 to whetever you can, in a strait one mile stretch. it is conducted on a unused air strip about 6 hours south of me. Im not going for any other record exept my own personal best. If I set a record on the way, than thats just gravy. My life long goal is to go 200mph in a street car(not on the street) Not saying for sure that this one will do it but Ill sure as hell try! So there you go. thats my plan. Any one want to sponcer me?lol

Ive had my TC up around 130. Prolly could go faster but I dont wanna try that on any road out here. It was dumb enough then, especially considering the tires and condition of the car then.

Ok I have already ran the aero numbers for a TC body. To reach 200mph in one mile takes about 800 rear wheel hp. Once you pass about 150 mph the aero drag becomes a real major player. The TC in stock form is not as aero as many think. The deal with Texas versus Maxton, NC is a longer shut down at Maxton. It takes a ton of brakes to get stopped at Texas. Yeah a chute is mandantory but it's not like a drag chute. It is a much softer hit. Ask me how many cars I have seen the ass end get lifted off the ground trying to use a drag chute. Not trying to discourage you, but want you to have real world advice. It is doable, but not as easy as many may think and still stay streetable. I have lots of data and software if you are interested. I also have a Land Speed TC project in the works now, but it's Maxton deal and maybe Bonneville if I can find a class it will fit into.

Oh BTW 200 mph is a football field a second just to put it in perspective.
