I know the GT-R isnt a 1/4 mile queen BUT - those following the launch control saga with the Nissan R35 may know that USA spec cars have had their launch control reprogrammed this week such that a) you CAN use launch control with VDC on and b) it will only launch at about 3000rpm now (vs 4800rpm or thereabouts before).

The expected results : it would blunt the performance right?

however it seems some guy has just set another stocker R35 record with the software update today.

11.34@120mph is pretty amazing given this is a 100% stock car.

I'm guessing the update involved a tad more than changing the launch rpm...

LSX-438....

The new launch control ran a 1.69 60ft on the Dunlops, its good, but not as quick as the 1.44 60ft generated on the old Launch Control ;)

Feeding in the clutches at 3000rpm with the traction control working isnt going to be as fast as sidestepping the pedal at 4500rpm which is what the old LC system did. Not many of these guys understood that unless they made the car 'hook' that axle tramp would destroy first gear....now its been made 'soft' there will be no such problems :)

hence my surprise Martin!

- especially at the 11.3 "stocker record"

personally i think it's quick enough, albeit with a 3000rpm launch.

Whats more surprising is the 11.6 from that same car 'dead stock' with no Launch Control at all :D

When I refer to 'hook' its hook-up off the line....

well that's true there could be something "special" going on with that car. Then again it's 3/10ths better from what we all expected (their prior results) - i think everyone just assumes it was going to be slower with the update, and yet it wasnt. I suppose we'll see a few others go out there soon and see what's what.

Edmunds Update Their Long Term GT-R and Get Faster

Edmunds long term test blog has been debating on whether or not to update their Nissan GT-R with the latest software update from Nissan for a couple of weeks now.

They finally decided to go ahead with it (for science!) and have now put it to the test. They’ve confirmed what others are saying and the GT-R is only improved by this update.

Results - VDC Off:

* 0-60mph - 3.6 sec (3.3 adjusted)

* 0-400m ET - 11.6 sec @ 118.9 mph

Results - VDC On:

* 0-60mph - 3.6 sec (3.4 adjusted)

* 0-400m ET - 11.7 sec @ 118.5 mph

Their “tips” on launching the updated GT-R may explain why their time is not as fast as we’ve seen. Some owners are reporting that there’s more to it than just planting the brake and the throttle. There’s a certain technique and timing required to get the best out of the new launch.

They also don’t mention what transmission mode they’re in since you can now do it in manual and auto in any transmission mode.

Check out the link below for the full article with details and a comparison to their previous best results…

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.

      And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.

      No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.
