Your running rwd though aren't u Dave?

That extra tractive effort that the front wheels give are what give the box a harder time

True, but I use MT's all the time now, holds traction in second (when warm).

Hell of alot of load IMO, but yes driving style would have to be one of the biggest factors.

i also ran the 1/4 mile with a stock box in my previous gtr which made 320awkw & managed a 11.1 sec with 129.75mph.

that was my last run, however, i crossed the line in 3rd gear & was bouncing on the limiter & my 60 footer wasn't that good (1.6sec?)

considering the relatively low power level i had at the time (hks gtss @ 23psi) that car was capable of a 10sec pass, but unfortunately i fudged it over the line :(

breaking boxes i think comes down to the driver & treating the box with respect, i.e. no flat changing

good time for that power and 1.6 isn't a bad 60 foot, but 129mph in 3rd ?

Plenty of room for improvement, Jez.

Quickest on stock box is mid 9's with over 550rwkw!

what car is that out of interest?

And yes, driving style makes a big difference to box survival...couple that with the fact that most of the boxes are over 20 years old.

age is also a big factor after talking to terry @ award diff about this in the past

good time for that power and 1.6 isn't a bad 60 foot, but 129mph in 3rd ?

i also ran MT drag radials which have a larger rolling diameter, how accurate is the timing equipment @ WSID?

my relatively certain that my limiter back then was set to 9krpm (i know it was a tad lower than my 3ltr which was set to 9.5krpm)

i actually have a pic of my car on my old HD and it looked fat with those MT's - i couldn't believe how much it filled out the guards with the 16's.

i also have my timeslip - i'll dig it out, if only i can remember where ive stored it after major home renovations.

Dave, how are you finding the MT's for regular street driving?

Unreal! Not going back to street tyres on the rear.

They are 275/17s at 20psi, im hunting around for some in 18s to throw on my street rims.

Stock box in my 430rwkw GTR, so far has done approx 2500kms of track work. Not a problem with the box, survives 2nd gear tyre warmups on slicks and 8000rpm launches with an OS GIken triple plate. Mechanical sympathy is a must - and far cheaper than a replacement box..... Of note this setup has not been on the drag strip (no track in SA) and I realise that a proper hookup on a prep'd track would probably kill it :-)

This warms my heart <3

Has anyone here cryo treated their box ?

I've been told it's effective but have my reservations.

Yes, both gervaise and I had our box's cryo treated at Dans insistence.

both car make over 400 kw's and both get dragged and circuit driven and have done for 3 years with zero gearbox issues.

Does it work, How do you prove it. You can only disprove it by breaking the box and that has not happenned to date so I'm going with a resounding yes! It does work.

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
