Mad Max: Fury Road

Payback says...

Me, I like my science-fiction when they don't cheat and make up silly stuff like a 'selectable' blower. Anyone who knows even a tiny bit about how a roots supercharger works sees those scenes from TRW and groans. The blades of the impellers need to spin because the carburetor is sitting on top of it. No impellers turning, means no air or fuel passing it, means the engine no worky .

That being said, I could see how a Paxton (basically a belt driven turbo) style supercharger could be set up to work, using an electric clutch from a air conditioning pump and some interesting intake plumbing. Instead of the best of both worlds, it's probably the worst of both.

You'd be better off with a variable boost NO2 system.

Now, don't think that I don't know about the 1920s Mercedes engageable roots superchargers, it's just that the one on the Interceptor in the movie isn't that style, and they merely shot the engine starting up when Max "pulled the switch".

Also, you don't start your interceptor with the blower engaged, you just don't. The whole point of a 'selectable' blower is you can turn it off both for easier starting and better fuel economy. Come on guys!

Nintendohemian Rhapsody - full parody

newtboy says...

Why does no one write odes to the Turbo Grafix 16? It was AMAZING for a 1990 hand held, playing all the regular turbo grafix games AND being a handheld TV. Nothing else came close for nearly a decade (if then), but no one else has love for the turbo. That makes me a sad panda.
I still play devil's crush every year or so! WHOO HOO!

Junkyard Turbo Chevy Datsun 240Z Autocross Thrash - Roadkill

Payback says...

"What do you get when you cross a rusted 1971 Datsun 240Z with a Chevy 4.3L V6 and a turbo from a Ford Power Stroke Diesel?"

You can safely remove "rusted" from this question. It's assumed.

The difference new engines make in Formula 1

TheGenk says...

from http://www.formula1.com/news/features/2014/1/15408.html:
Rule change: Introduction of new power unit consisting of a 1.6-litre V6 turbo engine and two Energy Recovery Systems (ERS)
Implications: The 2.4-litre normally-aspirated V8 engines of 2013 produced around 750bhp, with an additional 80bhp available for around six seconds per lap from KERS. The 2014 V6s put out around 600bhp. However, the two ERS systems (ERS-K and ERS-H) will give drivers an additional 160bhp or so for approximately 33 seconds per lap.

If there is a button the the steering wheel that gives an extra 100hp for overtaking by whatever method, I'm willing to call it push to pass. I expect that hitting the button would switch the engine to a high power torque mapping, use the MGU-H to spool up the turbo faster, and give a MGU-K boost exactly like last year's KERS button. I would also expect that not every team uses a steering wheel button for this function, but if Williams called it "push to pass" over the radio, I expect that they do. You could also have a separate engine mapping to do the same thing, and I expect that probably some teams do.

The RBR infringement was a bit more complicated than that. The FIA sensor was giving them inaccurate readings (it was reading high), and the FIA told them to apply an offset to the sensor values. They chose to use another method to ensure they weren't exceeding the 100kg/hr limit, and were excluded on the grounds that they had not sought permission from the FIA to do so and that it is not within their discretion to run a different fuel flow measurement method without the permission of the FIA.

I expect their appeal will be on the grounds that they did not in fact exceed the limit, and gained no advantage from their actions... and despite Christian Horner's level of confidence it could go either way. The last report I heard was that although they have lodged their intention to appeal, they have not yet actually tabled the appeal (but have a few more hours to do so).

Actually Mercedes were warned about the same issue. They chose to turn down their engines a bit to avoid the problem.

Formula one has been about getting around the rules at least since the 80s, and RBR have been very good at it. The camera mounting is very much in the category of satisfies the letter of the law, but very much goes against the spirit. I like the approach of using the camera mount as an extra wing actually (is it only the one team who did this?).

What they meant by this is to use all power available. They got 100l of fuel to go full 1½h race. The fuel flow is limited to 100l/h. That means they need to use around 67l/h on average, this of course decreases during braking and is almost at max during acceleration. Also energy recovery and the release of that energy has some leeway to be used in different ratios, it is limited to 33s per lap. How that energy is divided, is up to the team.. So they will have the full boost of 160hp from ERS and full 100l/h fuel flow when using "push to pass" button but it's nowhere near the common definition of that function. Traditional push to pass is high boost, on 2014 F1 it means few percentages of power. The correct term would be "overtake mode".

RBR infringed fuel flow rule and no other team had been even warned, FIA has guidelines that teams should calibrate with enough margins to void minor differences between sensors. RBR refused to do this and counted on FIA not counting that marginal change. FIA had stated pre-season that in no case there will be extra fuel flow allowed, it's almost zero tolerance policy.

They've done this before, made a marginal rule infringement and got away with Charlie Whitings slap on the wrist:"change it to the next race".. Their camera mountings is already one of those little things that is technically legal and at the same is not.. It all depends if the TV crews can find a suitable camera. If they say "no", the rules are clear: they need unobstructed view.. That small hole hardly allow high quality picture, the only lens that could even remotely suffice is fisheye lens with a mask: it is not their standard equipment.. RBR most likely will have to change those too (imho, so should merc camera pods and mclaren parachutes too). Compare that to Williams 360 camera pod and it's pretty clear what FIA means by "enough room to fit camera" means.

Last year they had holes on the floor in monaco: ruling was, change them to the next race.. Then there was the TC scandal, RBR used illegal engine mappings.. They used them last year too when there was a ban of feeding fuel to exhaust during zero throttle to feed the blown diffuser: RBR chuckled and used them anyway.. They still have the duct inside the nose, it violates the intention of the rule but is legal technically. Of course the severity of the punishment is a clear sign: FIA just showed that no more of that bullshit, RBR has to start respecting rules.

Jet sucks a safety pylon into its engine

zor says...

Wow! Since when do they set traffic cones in front of the engines! The engine may not have been 'damaged' but it would have had to be completely inspected and that would have put it out of order for days or weeks I'm positive. You can't just suck shit through a turbo fan and go on flying (safely). Yes, technically you can do it.

Transforming Formula One: 2014 Rules Explained by Red Bull

oritteropo says...

Yes. The naturally aspirated v8 engines were increasingly irrelevant for road car technology, so the aims of the new engine rules were to introduce the types of technology that are relevant to road cars (turbo, regenerative braking, fuel efficiency).

Two less-intended side effects are that these are the most expensive engines ever (in an era when everybody is talking about cost reductions!) and that everyone is wondering whether anyone will finish the first race...

They actually had the battery packs last year, but this year have reduced the fuel allocation by a third but without reducing the power output of the power units.

Cool *animation. Can anyone explain why they need such big battery packs and use regenerative breaking? Are they driving hybrids or something?

AeroMechanical says...

It will be interesting to see how combining an allowance of 5 engine blocks with totally new engine works out... particularly after the results of testing.

In the pool amongst my friends, I have 12 cars managing to finish at Melbourne.

Anyone know off hand whether the turbo counts as part of the "complete engine unit?"

Yes, and vibrating controllers. I wasn't a console fan back then. I only owned Atari 2600 and borrowed a Turbo Graphx 16 for a week.

Never got the hype around GoldenEye.

Played it on a friends N64 and it felt like an ok FPS, but wasn't really that memorable. Is it just because it was the first decent console FPS?
