Some serious modifications in progress (600WHP, transmission upgrade)

HKS GT570 @ 17psi - 600+WHP

Here is a teaser pic of some work we are doing on some transmission upgrades

here is the scoop on the transmission
CBA-R35: First GT-R transmission and differential development Upgrades!

but that dyno is not from the same compainy.

I wonder how successful they'll be with the clutch packs. An upgrade can't be that easy. With a normal transmission, stock clutches are compromised to offer smoother changes. With DCT, the change is set to occur almost instantaneously anyway. If strengthening it was so easy, wouldn't it already be that way as stock?

Maybe the gearbox is not strong enough to cope with much higher torque outputs and so Nissan made the clutch so that it slips before the gearbox gets too stressed. Only time and tuning will tell how much the box can cope with once strengthened clutch packs are out there.

I'm not so sure - seeing how close Nissan have worked with the Japanese government to ensure their cars are strictly road legal, it wouldn't surprise me to learn that they intentionally didn't over-engineer components as they did with the RB line.

the stock clutchs start to slip around 600hp give or take.

The R35 and the IS-F are the only cars that largely surpasse the 280HP gentleman agreement (wich isn't written down somewhere, but kept car makers in the line in the last 30years, as typical japanese nobody want to be different from the group). Now that has changed and makers don't need to keep them selves chained with thoses 280HP limits. The problem is that in order to give the japanese customers in the last 30years cars that were still more, then simple 280HP cars, they had to overengineer them (also as japanese customers care more about such details then about looks of a car).

That has now changed and the government allows anything now. So no need for overengineering for now, as the GTR and the IS-F can be considered overengineered, as they simply exceed 280HP. Then the new j-customers are very different from old times, the maniacs obsessed to tune cars are long gone and most young people don't care about sports cars anymore today. So the new customers will enjoy the new expensive sports cars the way they are, they want a car that is not related to the tuning maniac scene.

That's probably why cars won't be overengineered in future in japan (but still being state of the art , bringing high end techology for the bargain)

When I look at this thread I feel like looking at a Ferrari thread, where you try to modify a bloody expensive part and which at the end only ultra rich peeps can afford to do.
It's an other world!

First, I have to start by saying that I enjoy reading your blog for its up to the minute breaking updates. But could you please either use a dictionary function or a spell checker? The grammar and typos in the blog make me cringe.
