Yeah I thought it was an interesting story when I read about it. One would think more info would have surfaced after a whole year though, surely?

It has - a year ago it was mostly just rumour and innuendo, and we don't post anything until it is confirmed as fact.

Racecar Engineering only published their detailed article about the tunnel in the current issue of StockCar Engineering, and that article is only available in the print version of the magazine, and not on their website yet - as soon as the new article is available on their website, we'll provide a link to it.

The new article goes into huge detail about how the inside of the tunnel is set up, how tests are carried out in the tunnel, and the exact advantages of using a full sized tunnel over a wind tunnel.

The new article also says that a steam catapult like what they use to launch fighter jets off carriers has also been considered to increase the maximum speed possible inside the tunnel.

It also includes full details on the equipment used during testing, which includes datalogging by Pi Research, a pair of AQS Air Quest 1000 dehumidifiers, and a Vantage Pro weather controller - so essentially they can set the environment in the tunnel however they want it, for testing cars at different humidities, air temps etc.

The tunnel even has a turntable in it at the end of the tunnel so the cars can be turned around quickly for the next run, and Racecar Engineering's new article also reads ...

The test car can also tow a second car through the test section to simulate drafting, and multi-car tests have been conducted with two cars running nose to tail or side by side

As soon as the new article is available online, we provide an update and links to the new article - it has some very interesting diagrams and illustrations, and completely new info about the inside of the tunnel and how it is used.

Oh, awesome, well be sure to let us know when your next massive industry insider scoop happens on this one.

Huh ?

It's an interesting story which clearly hardly anyone in Australia has heard about, and which up until Racecar Engineering confirmed the story in their very latest issue was mostly rumour. So now that a respected magazine like Racecar Engineering has confirmed it in the very latest issue of StockCar Engineering, and provided more technical info on it, we shared it with the forum - simple.

As I said above, a year ago it was mostly just rumour and innuendo, and we don't post anything until it is confirmed as fact. It's now confirmed as fact, so we posted it.

If unlike the vast majority of forum members you're not interested in our posts, feel free to ignore our future posts - I for one found it a very interesting story, and clearly many other forum members did too :P

    • sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving. 
    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
