Top Speed of r33gtst

[KRiMiNaL]

What is the top speed for an r33 gtst.

If i changed the ecu how fast would i be able to go, ive only got a piggyback.

[Duncan]

no way, if you were on the Pac Hwy you can't have been going faster than 60klm/h.

I suggest you edit or delete your post ASAP, SAU takes posts about reckless driving very seriously....

That's pretty dangerous for you and more importantly other people! If you don't respect your own life atleast respect others. In the right environment it's ok - Take it to the track/drags.....please.

[gatty]

i assume he said he was doing 180 and it was cutting out?

new ecu would fix this, but why would you want to go that fast?

[Cubes]

but why would you want to go that fast?

Because he is a Kriminal.

Pay what ever it costs you test your top speed at your local track.

Its a lot safer and will prevent you making the news WHEN not if you get busted.

"Yet another Skyline clocking 200km/h"

Its not some thing we really want to hear.

[KRiMiNaL]

For Cubes and Gatty i dnt wana go that fast im just curious of the top speed with a new ecu. I jst wana learn like many other people on the forum about the rb25's potential.

[Cubes]

Now that you have reworded the origional post.

That really depends on how much power and rev's you have.

I would say 240-250-260km/h is within reach.

My little old VS Commodore 5 speed with a few mild mods used to only 'just' crack 250km/h so no doubt a mild RB25 which makes around 380hp will be able to crack it also. Depends if you run out of rev's.

Do the Math.

The standard soft limit is fifth gear at 5000rpm. at that speed you are doing approx 190kph

If you divide by 5000 and then times it by the redline (7200), you get 273.6kph.

Didnt you learn about ratios in school?

[2rismo]

The standard soft limit is fifth gear at 5000rpm.

Soft limit? What's that then? Haven't heard that expression before.

so at 8krpm you'd be nudging just over 300km/h? Must try that out!! (Private closed race track of course.

Use a dyno....

Its a very very safe way to check out a top speed.....

[Col-GTSX]

Although wind drag and friction are a little different on a dyno so id say take the results with a gain on salt... But it would give you a pretty rough idea....

[600hp]

Drop it out of a plane and get the cops with there radar to be standing underneath it and get them to check the speed.

HAHA thats a joke !

the cops wouldn't do that for you.

You don't even need 250hp to crack 250km/h.

[quincy777]

I did 240 comfortably with only exhaust and air filter.

[INASNT]

I did 240 comfortably with only exhaust and air filter.

Where exactly in Melbourne did you do this? And how did you measure it?

[Col-GTSX]

Good call INASNT....

As above posted that these results should be tried on a racetrack or dyno.....

And yeah how did you measure it.... I bet he says with a 320kph nismo dash... LOL

[Cubes]

You don't even need 250hp to crack 250km/h.

haha.. Come on buddy.. This is a VS 5ltr Slugger Commodore we are talking about.

250km/h is a fair speed, most new cars even the ones making 250hp at the fly would be pushed to get 250km/h.

[benm]

I was actually referring to the bit where you said "no doubt a mild RB25 which makes around 380hp will be able to crack it also."

...and im saying you dont even need 250hp to crack 250km/h (and you dont even need 7,000+ rpm).

[Duncan]

I used to hit 192km/h every day when I live in the NT, as measured on a GPS speedo with the standard rev limit

And thank you for fixing the first post

[Cubes]

Benm,

So the R33 N/A ~150kw will crack 250km/h..

I don't think it would.
