1991 Top Speed??
 

Hi everyone:

I just got my first Vette. Turquoise 91, Sport Coupe, 6 Speed with 96k miles. It is on very good condition and I paid $ 8500.00 for it.

I was wondering, what is the top end for a stock 91, 6 speed Coupe??

Thanks,
Love the forum, I get on every evening for at least 15 minutes. Very informative and entertaining.

I am in Miami, FLA. Any other Vette owners in this area want to hang, drop me a line.

my 88 auto when stock topped out at 153. i havent topped it out lately, but ive done some top end mods, so im guessing i can hit ~160. btw, 15 minutes is all youre here? you need to stay longer. :cool:

Should be about 155mph if in good working order. :)

Welcome to the forum. Man you made an awesome deal, my father-in-law paid $400 more for a 87 two months ago. I hope you enjoy the car, it should top end at 150-160 mph. Stay a little longer dude. :cheers:

Re: (XtremeVette)
 

I never said I'm on 15 minutes a day, that was the thread author. Hell I'm on it like 15 hours! :)

Re: (scorp508)
 

Rear gear would affect the top.......so a lower 2.59 should go faster top speed than a 3.07...etc....What I would like to know........Is the TOP SPEED for ALL 91's 155?? I have heard much more than that.......but in the twisties here in the mouontains.............I'll never see those numbers!

Someday though.........! :yesnod:

Re: (KNCRSR5R)
 

Theoretically yes, if the car had enough HP to pull through the lower (numerically) gearing.

Re: (scorp508)
 

depending on tranny too. standards get more power to the ground so the usually top out 2-3mph higher. 15 hours a day :eek: im glad im only at around 12 :)

Re: (KNCRSR5R)
 

Couple of nights ago I tried this computer performance analysator software I donloaded from web (can't remember the name of it). Among the hundreds of other cars there was a '90 L98 automatic with power, tq, gearing, weight, wind resistance, tire size etc. etc. factors already entered.

I didn't check what 6 spd can do however. Early '90's test I saw in a magazine stated that the top speed should be 150mph.

The '90 has virtually the same figures as my '91, right? OK, I tried this thing and simulated acceleration and top speed performance for an automatic.

The top speed it calculated was about 151mph for 2.59 and 132mph for 3.07 cars. That was a bit disapointing. European/Japanese sportscars have much higher gearing but they are getting much better VMAX. The difference being that they rev much higher. By increasing the red line (in the sofware) I was able to get faster topspd.

Ok, I don't really need very high topspeed but it would be nice to know (brag factor ;) ) that my car could do better than 132mph as any T4/T5/T6 Volvo or V6 VW or whatever could beat me at will (me being faster in acceleration of course). Topspeed of 160-170mph however would make the car untouchable by virtually all else than real sportscars.

Am I right: if I want better topspeed I need more revs? What options are there to get more revs out of the motor without losing too much low end tq?

Greets,

Re: 1991 Top Speed?? (vmaxer)
 

I have gone 135 in my 91 and had more left but had to lift because the tires are a bit old and in need of replacing, and the front rotors need to be recut, and the roof was off, so it was loud and scary! I think 155 with a long enough road. What gear are you running?

I am in Miami also- I saw one like yours in front of the Eastern Financial Credit Union, were you makingthat 1st payment?

Re: (ToniH)
 

That is definitely not the top speed for a 3.07 car!! My 3.07 coupe has been over 150mph a few times.

Re: (scorp508)
 

> My 3.07 coupe has been over 150mph a few times.

Glad to hear that :D It's automatic, right?

Haven't tried it myself as the speeding ticked system is quite harsh in our Country nowadays. The fine is dependent in your income and last year they made illegal to lie ;) ones income. Before that everybody said they were students or something and got away with small fines but now it is worse. I mean the worst fines I've seen have been like $75.000 for some wealthy indivituals. In worst case even I could get a fine that equals the value of my car ....cannot affort that unfortunately...got to try it some night though with a radar detector to be sure... ;)

Thanks,

ToniH

I have 2.73's in my vert and I have had it to 147 and it was still pulling let off because I started thinking.BTW it's an auto. Welcome to the forum. Sean :cheers:

Re: 1991 Top Speed?? (vmaxer)
 

I have seen 145 with a stock 91 6 speed. It had more left too but I didn't...:)

Re: (ToniH)
 

Nope, stick.

Re: (ToniH)
 

Nah, that's not right. Both auto and stick L98 are the same top speed according to all tests I've seen. beginning in 1985 they all did at least 150mph. My '85 3.07 rear auto has done 140 before and it had plenty of room left for more. I have only had my '90 up to 120 a couple times, but I know it will have no problem getting to 150 because it feels much stronger than my '85.
