I was watching a NASCAR race the other day... 165MPH... Slowest corner on the track... Top speeds around 185MPH...

Fucking NUTS!!!

must've been a short track. the big ovals they will hit well over 200mph. top speed i've seen was near on 210mph (over 335kmh)

nascar has moved to efi.

the sprint cup race i watched a few weeks back had a bit of a tech thing on it and the car they were showing then didn't have an ecu. they said it didn't even have a fuel sensor.

the average lap speed for pole position at the 2012 daytona 500 was over 194mph, even with restrictor plates. race lap speed is higher because of drafting. but the corners there aren't that sharp. they still sit on around 190mph through the corners, and hit just under 200mph at the end of the straights. at tracks like texas they don't run restrictors. they drop down to 175mph in the corners but get back up to just under 200mph. they also rev up to nearly 10000rpm at texas, while daytona they only rev up to around 9000rpm (because they are flat to the floor pretty much the whole time)

the daytona lap record though is from 1987 though, with an average speed of over 210mph. pretty good for a dirty old v8, lol

No idea what track it was, but even my ass puckered up a bit when one of the guys exited a corner in a massive slide... And held it...

They were only revving to a bit over 9K from what I was seeing. Around 9.5 IIRC.

They are going EFI next year I believe.

One thing you can say about nascar is they have remained faithful to the formula.

NEK MINNIT

All spec car series are shit.

EOB.

On the engine front... it has been reported in AA that the KR-Nissan-Nismo engine team have signed off on the powerplant.They have chosen the 5.6L DOHC V8 engine as used in the Nissan GT-R GT1 project in Japan.

How they go about reducing the capacity to 5L or less is anybodies guess. I assume they will sleeve it down rather then throw in a new crank but who knows.

Holden look to be preferring a Chev crate engine on the basis of cost. So you have Nissan running high tech, ridgey didge race motor, with twin cams, 4 valves per cylinder and lots of modern race design nice to haves VS Holden looking for a cheap crate Chev engine to build and spec up.

I am guessing the Chevs are going to get some extra displacement if they are to have a hope of matching the Nissan in anything resembling a short sprint event.

Seems odd that Ford and Holden are contemplating an engine change. Surely the change to COTF is expensive enough in the short term without taking on engine development

And Rick Kelly is off to the USA for a car show to promote the Altima...so I guess thats what will be wearing Jack Daniels war paint next year

Ford has a tasty 5L 32 valve engine they have been using in grand am sports cars for a few years. Making an easy 500hp in near standard trim

That series works well with Porsche, Lexus, ford, chev etc all running spec engines producing the same performance

Would be easy to implement for the supercars out here

Be interesting to see unravel.

Anyone know what the GT1 spec Nissan donk power/rev wise

I also find it funny that Holden went to the HMS engine because the chevs were down on power compared to the D3 headed Fords. But now they want to go back to chev after all the money spent on copying the ford motor and creating tooling/machinery to cast them

I would like to see ford adopt the FR9 and detune it down from NASCAR spec that way the Holden guys could run the current 13deg chevs and would open the gates for Toyota and Chrysler

Someone should probably tell Nissan you don't go into motorsport to make money.

Also, what if they don't win a single race?

lol. the shame. that's twice this week I've been wrong :P

Unless I've missed the point, the altima is a fwd shitbox that is going to replace maxima in the road going line up? The replacement for a bluebird...or a 200b?

I wonder if nissan oz are aware of a model in their JDM lineup called "skyline"

  • 3 weeks later...

I like the fact that they're claiming it has more road going parts than the other two...

Yet, they're changing the floor pan, and a completely different engine to what you can really buy at the dealership...

Also, Duncan, are they making a 4 door Skyline at the moment?

looks like the V8's will be back at Eastern Creek in August this year,

Yes, will be good to see them back at the creek especially with the time attack cars being there later in the year too !

    • Why are people so insistent on making dirty water?!
    • Fark what are the changes of that snapping like that, clean. Nek minnit, custom radiator goes in, with built in oil cooler like those discontinued PWR ones from yesterdeacades ago
    • 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)
