Weakness Of The New Gtr?

[NISZILA]

A few interesting comments. To those who don't like what I've said, sorry if I offended you. The only reason I pointed it out is because I find it interesting and wanted to see others point of view. As I said before, I don't think the nissan engineers have missed this. I'm sure they have done plenty of R&D and have the whole thing under control. I was just thinking similar to what warps and sh@un are saying. Just think its an interesting setup and worth talking about.

... and for all of those who think I'm trying to find a weakness lol. Don't stress. I was looking at all the pics cause I think this car is awesome. Just spotted this pic and it got me thinking

[Zoggy]

where is MonaroCountry ?? love to hear his opinion on this!!!

[SilverECR33]

look at other cars with 2pc and 3pc designs. they all become faulty after time and wear. I reckon a 1pc replacement will be on the cards, for the front drive shaft after time and wear come into play.

Been looking through as many photos and specs as possible. Can't wait to see this beast. When I saw, this photo, however, it got me a bit concerned.

As you can see the gearbox is located at the back, which is great for weight distribution. The concern I have is the shaft that travels from the engine to the gearbox. This shaft will be spinning up to 7-7.5k rpm. For a shaft of this length to be spinning at that speed, it would need to be perfectly balanced. This is very difficult to achieve. That is why formula one have gone to V8's. Because the shorter shaft is easier to balance at those high speeds. If the gearbox was in the front, it wouldn't be a problem as the shaft would be spinning a lot slower due to being geared down. This is how most rear wheel drives operate.

What do you guys think?

Roll down to "2-3. Reduced powertrain vibration"

That is an awesome link. Thanks mate

Got a lot of reading to do now

F1 V8's have more vibrations than the V10's ever did

Stop giving the OP a hard time. He's thinking about this stuff and has the balls to post up the question which started the discussion. Which is what forums are for

I'm sure that if a friend asked you a question like this you wouldn't take the piss out of him, you'd just explain that it's not how it works

I thought the GTR was going to be running an auto only. Hence all the comments on clutch dumps, and the syncros "breaking" etc, are a bit useless... Correct if wrong.

And the only real issue with the GTR is the damn asking price!

[ferni]

No, it's running a DSG box.. dual clutch flappy paddle box.

[Inline 6]

weakness of the GTR you ask?

we gonna have to wait for takumi to find it on the downhill in initial d stage 5

[Keeper]

What do you guys think?

I think the biggest concern s that car doesn't have any seats let alone a body, make for a shit comfort factor

[R34GTFOUR]

No, it's running a DSG box.. dual clutch flappy paddle box.

haha i dont count flappy paddle box as manual

if it doesnt have a physical clutch petal that i can stomp on then its not manual imo, i hate when manufactures say semi-manual ITS AUTO lol

i'm sure shcumaker chucked a hissy fit too when ferrari told him he had to use flappy paddles on his "auto" F1 car. harden the f**k up.

[sh@un]

i wonder what % of people whining about the lack of a clutch pedal in the new GT-R would actually be able to afford a new one?

hmmm....

maybe Nissan could make a cheaper manual version to appease all the 3rd or 4th owners

[scandyflick]

they can market it along with the R35 GTt...

[Sydneykid]

It is hardly a new idea. For example Alfas had the transaxle, front engine combo in 1978. Never had a problem, well not with the tailshaft anyway.

... and Porsche with the 928.

[Adriano]

... and Porsche with the 928.

and 944, 924

[Black Betty]

flappy paddle box.

haha thanks clarkson

yeah suprised the porsche comment just came up. the 924 started in the 70's didn't it and it had the rear mounted box and surely considering it was a bit of a unexpected change for porsche to be running FR layout they didn't spend all their savings on engineering it to perfection. obviously it wasn't a lego piece made by a 3 year old either though but you know what i mean.

My un-engineering qualified brain is wondering now how the drive is delivered to the front wheels. i'm gonna have to go back and look at the pic

[Black Betty]

ah yes now i see they're 2 drive shafts. looks like the 4WD things i used to make from the that technics lego when i was a kid, ok maybe a bit better than that.

no wonder the thing weighs 1.7 tonne though... not that carbon fibre they're made from (or whatever light stuff it is) really weighs a lot.... but still the car weighs a lot. whats with that?
