Gtr Topspeed

[donkey]

hey does anyone know what the topspeed of a r33 gtr is? what does the car gear ratios alow the top speed to get to, if in theory you had the power to get there?

hope this this makes sense

cheers

Over 330km/h i believe.

Thats stock gearing.

Thats stock gearing.

With a 11krpm redline it could do 420km/h.

Approx 340km/h at 9krpm.

R34 GTR the same?

The ratios are different but they will all do those kinds of speeds if the power, strength of drivetrain and wind resistance is all living in 'the perfect world'.

Obviously there are restrictions and this is based on the estimate of ~3000rpm in 5th at 100km/h and every 250rpm higher is ~10km/h faster.

The easiest way to tell is to do 100km/h, note the revs, then go up 250 or 500rpm and use this to calculate your top speed at redline.

Keeping in mind that it will require approx 450hp at the wheels to go around 200mph and another 100hp at the wheels to go another 20mph. This is approximate also as relayed to me by a mate of mine who races on salt lakes.

just trying to figure out (i have no idea if im right) but say you made 7000rpm the limit, would not all the cars of that model have the exact same top speed because of the final drive/diff ratio?

if in theory you could reach it power wise????????

oh cheers nismoid, i guess that answered my question, ha

cheers robbie

They do not all have the same gear ratios.

There are different things that will effect the top speed: Gearset ratios, diff ratios, tyre size, top rpm, and finally the car's wind resistance.

But yeah, if you have 2 R32GTR's exactly the same, they would do the same speed at 7k

hey thanks for that

What about in 6th? Same thing applies I take it.

Do I really need to answer that? If you have the Getrag box, then do it in 6th instead.

You would need a long smooth strech of road, to go top speed. When i went to sandown in my 32GTR i only got up to 210kms, So it be had to reach it on a track.
