V-spec Version Discussion And Speculation

[sh@un]

If the V-spec goes on sale before Nissan AU start selling standard R35's, that means we can still get them as private imports, yeah?

lol!

the f430 gearbox is on par with the gtr.

i personally think the F430 Scuderia gearbox is better than the gtr but i havn't driven a f430 or a gtr for that matter...

Actually, the F430 gearbox shifts slightly faster than the GTR's but loses out in terms of smoothness.

[Ultimategtr]

doesnt the GTR shift in like .1sec or so?

[SS8_Gohan]

off the top of my head... could be hideously wrong

GTR = .2 second shift

F430 Scuderia = 60 milliseconds (maybe even down to 20 milli in full race mode)

still waiting to read a reply from 2 pages ago about the plasma bores and if they will handle more then 600hp and if 100 000km rebuild is true?

If you are making serious power a 'freshen up' style rebuild occurs often. The more power the more frequent the rebuild. Race motors are rated in hours. A freshen up isn't much dosh compared to what you have blown on replacement brakes/tyres by the time it comes around. No big deal.

i am i the only person to notice the carbon ceramic brake rotors on that car?

No you are not

[sh@un]

carbon|ceramic composite rotors- just awesome

that'd be a first for a Jap manufacturer then

i am i the only person to notice the carbon ceramic brake rotors on that car?

maybe compare our respective post dates, perhaps?

F430 Scuderia is 60 milliseconds (in race mode) as stated above.......the limiting factor is the synchros.

lol no. but your the only one who didnt bother to read the thread before posting

[t01-100]

gees guys... didn't realise we'd become so anal all of a sudden!

[Duncan]

typical rx7 driver.

how will the carbon brakes work from cold on say, a targa stage, stuart?

btw isnt the gtr gear change time 0 sec when you change to the preselected gear? surely thats the whole point.

Ok, after reading the gearbox talk on this thread i have to say DSG, selespeed, F1 transmission or whatever you want to call it isnt always perfect. I have been a mechanic working on Ferrari's pretty much exclusively for the last 3 years so i have a tonne of experience dealing with the F1 box. Now for track days or blasting through the backroads the F1 box is simply awesome on the F430 (havent driven the scud yet but am sure it will be better still) but it can be temperamental and its reliability is starting the become an issue as the cars are now a few years old. (the 360 and 355 F1 boxes are rotten in this respect). Now i know the system on the GTR will be different but im sure similar problems will eventually arise such as dodgy pumps, actuators, release bearings, clutch position sensors etc..... All things that a normal manual box doesnt need. The F1 box in the F430 is an awesome bit of gear when its all working great but an F430 with a manual box is still are beautiful car to drive and i cant see how it would be any different in the GTR. About 40% of ferrari owners still opt for the H pattern so it is still relevant to ask is the GTR will have the option. Saying all that i think its probably best for the V-spec to be DSG only (360 challenge stradale and Scuderia are F1 only) and it would be a good idea for the standard GTR to have the H pattern as an option. Hey it will be better for alot of us in 10 years time when we get our hands on second hand ones not to have to worry about alot of the problems on an old DSG box can cause. Also there is probably 15K worth of gear needed for the DSG which could be knocked off the price on a H pattern car.

Also with my experience with Carbon ceramic brakes, yes very expensive but will last much much longer than a standard set. If you do alot of track days or hard spirited driving then the cost difference will eventualy mate up and the stopping power is unreal. I have done race prepping on an f430 challenge for 2 years now and we still havent had to change the discs on the car just the pads. And yeah, discs are around the 8k each mark.

how does the ferrari f1 box work? as compared to the gtr's dsg

[RNS11Z]

rev210, i wonder how much it will be. what would be the case though, just respray the bores or change the whole block? then rebalance everything and throw some new rings in it. and will nissan dealers facilitate this sort of work????

[dmr]

wow, this car is an animal. great to see nissan using their technology at it's best; as always.

hope to hear of this X model or whatnot.

I really couldnt tell you as i havent seen alot about the way the gtr box actually works. Id take an educated guess and say it would be very similar except for the clutch setup.

Very few similarities apart from the fact that you dont operate the clutch yourself and you change gears with paddles.. the Ferrari F1 box and the Nissan DSG are not easily comparable as there is not much similar to compare.

[nickcorr]

Yes competely different....

The Ferrari F1 gearbox, is a normal manual box with some clever software and actuators to operate the gear selection and clutch. The Alfa Selespeed gearbox is actually a development of the original Ferrari F1 system. The BMW SMG and Toyota SMT are very similar in this respect.

The GTR transmission has more in common with the VW DSG, Audi S Tronic and BMW M-DCT. With these systems the transmission contains two clutch packs. One looks after odd number gears, the other even number gears. As the car accelerates in first, the transmission has already selected second gear, and so at the change point, all it needs to do is to declutch first, and engage the clutch on second. Once this has been done, the transmission can pre select third gear and so on. This allows a shift to be made in 8 milliseconds. That compares with 150 milliseconds for the F1 transmission in an Enzo.

With the GTR using wet clutches, the life expectency should be higher than the F1 type clutches that get absolutely trashed during parking, and also by people driving them like an auto, holding the car stationary on hills using the transmission rather than the brakes.
