wierd... expensive tho $550 to get a 'tag lock down system' installed...

interesting idea tho... wonder how it works with AWD... and the weight/aero part of it?

what the fark is with that gay video of those girls dancing around??!?

Also:

"With a racing membership, each vehicle is set up in Drag Tag’s workshop where it is weighed, and the frontal area and drag coefficient from the car's manufacturer entered into a computer. Using this information, we are able to assign a carefully-calculated air resistance equation."

Haven't had my car on it mate...would love to though.

From what I've seen, the results are incredibly accurate compared to others' real-world drag times.

I need to find the photos of the Linux arrays running the thing. The number crunching is in-farking-sane!

Adrian, are you affiliated in any way with Drag Tag? Just would like to know if the opinion is unbiased.

Without airflow how is the engine, brakes, etc. cooled?

With 4wd cars how can you turn the wheel? As i have seen some close calls if the wheels are not kept straight.

I've been exposed to it and its development in various ways for a couple of years. I don't work for them and they're interstate! :O My employer has advertising at their premises and vice versa.

It's just a cool concept. Skip the drag racing component for a sec and think of the driver training aspect. Controlled environment driver education in real world situations. Great idea with heaps of promise.

I support any idea that increases driver training and road safety and gets the fast cars racing where they should be.

Brake cooling etc..... dunno. I'd send em an email. Every question I've ever asked has been answered promptly and sensibly.

Great.............

Would be good to get some answers. For 2wds the front brakes wont matter as they are stationary, but the rears may get a little warm :D.

The concept is great, hopefully it kicks off for them.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
