2nd Gear Launches....

[mazgtr]

Just reading an old High Performance Imports, and in it Ben Ellis tests a R32 GTR fitted with a CAT back exhaust and a K&N filter. Hes able to post a 4.77sec 0-100km/ph time and a 12.97sec 0-400m time. He makes the comment though that the 0-100 time was done all in 2nd gear, i:e he launched the car in 2nd gear and removed the need to make a gear change to reach 100km/ph.

I was just curious if anyone else has had a go at launching their car hard in 2nd gear, either at the strip or even on the street, especially in a GTR..

Cheers...

shit! thats pretty f**kin sick!

Even considering the time saved by avoiding the 1-2 shift, you'd need a damn good launch to compensate for the lack of early acceleration (compared to first gear). Although I have heard of other cars acheiving their best acceleration starting in 2nd gear, including a lightly modified EL Falcon which simply toasted the rear tyres in 1st gear :lol:

you'd prolly find he'd go better launching hard in first as long as you can change gears well enough.. launching in second gear hard would just put way to much stress on everything in my opinion

hmmmz intresting... 1st to 2 gear could be .5 or 1 second and launching in second gear... does he have a 1/4 mile time to compare with launchin in 1st?

Are you 100% that he didn't mean the 0 - 100km/hr sprint was only doing using the first two gears? ie first and second only.

Because I'd be suprised if starting in 2nd is beneficial, and more importantly you'd want a decent clutch to hold up to redline 2nd gear launches. Let alone the res of the drive train...

Although you sound rather confident in what he said, and if you're correct, then that's pretty cool

yeah I agree Tommo, I think he meant the highest gear he used was second, which you can do with a few extra revs over the standard limit I think. Or bigger tyres. Or longer diff ratio

[siksII]

r33 gtrs do 120km/h at the redline in second, what do 32gtrs get up to? I thought they would have been the same...

[Emre]

All the ratios between R32 and R33 are the same.

Even though i've never tried it, i am thinking a second gear launch would cause the car to bog and return average times.

I am with Tommo and Drunken here. I think Ben Ellis meant that the 3rd gear wasn't necessary.

I have tried to launch my r33 in second and it was about the same as first IMO, BUT i was launching at 11 psi (using PFC Pro launch control) and my clutch would only last one go and even then I think it was slipping. :{ (Ceramic button)
