Vagina hurting? Vent in here.

4K rpm in the 280? That was more like 85, not 120. Not a race, just more BS from another 280 owner.....

Its well known that a stock s130 can do 130mph, and do it at a little under 5k rpm.

In 4th, you have a 1:1 transmission ratio. If you have 5th, that is OD gearing. OD is either 0.864 or 0.773. We will assume it is 0.773 to give you the benefit of the doubt. I'm giving you the benefit of the doubt thinking that you have the 1980 transmission and rear end, rather than the 79, which is worse.
Stock tire size was 195/70 VR14.
If we calculate based upon that, we find that you would be running 113.7 mph at 5K rpm - and that is if you have zero wind resistance, and no coefficient of drag. You would have to do 5700 rpm to reach 130mph utilizing your OD. Your 4th gear couldn't reach 130mph at even 7K rpm.
Do you have any idea how long it would take you to reach 130mph in OD?

Ouch....again.

All of this is pointless... Considering I have another gear.

Do you have any idea how long it would take you to reach 130mph in OD?

Not that long at all? Considering I have done it, I would say from 80mph it took me maybe 1/3 to 1/2 of a mile.


And the car is an 81 2+2, besides an 82-83 turbo that came with the B&W T5 my car has the best drive train for any L powered car.

You have a 5 spd. I was quoting 5 spd transmission ratios. You do not have a 6th gear.
Let me make this simple.
You have an 81 2+2, then your rear end is a 3.9 stock, which is the best you could have for acceleration, but hurts your top end.

The T-5 only came in the turbos, the non-turbo were not T-5.

If you have the stock transmission, your gears are:
1 3.062
2 1.858
3 1.308
4 1.000
5 0.745

If you changed the transmission to a T-5 out of the turbo, your gears would be:
1 3.500
2 2.144
3 1.375
4 1.000
5 0.780

Either way, you have the same ratio for 4th, and 5th is a minute difference. Your top speed is governed by your gear ratio. You can calculate what your car can and cannot do with this data, and at a given rpm. Your valves float above 6500rpm, correct? So we can calulate the maximum speed that you can do in each gear as well.

You are not doing 130 mph at 5K rpm even in 5th gear - physical max is 119.3 - and I'm giving you every benefit of the doubt. You physically do not have the gears to do it below 5500rpm. The only way to do it would to be put on taller tires, so that you change your gear ratio. For this, you would need to make more power also, as OD is a very weak gear and will not pull well. 1/2 mile is a long way to have to go to creep up 10 mph.

So your whole argument is based around 4th gear...?


I have been in 5th gear and pulled to right at 130mph and held it for while, long enough for my friend to pull up next to me and verify I was doing 130, im pretty damn sure I was at 5k rpm too, not 6k.

What part of "You are not doing 130 mph at 5K rpm even in 5th gear - physical max is 119.3" do you not understand? You claimed 130 at 5000 rpm - which is not physically a possibility. 5500 rpm is the minimum physical engine speed to reach 130 mph vehicle speed - and that is not calculating for road resistance, wind resistance, and coefficient of drag.

I am not saying that your car cannot do 130mph, just that it is not doing it at only 5K rpm, as you stated earlier.

5 speed with R200

205/70/14 tire


Not possible eh?
