The name says it all, with NO turbos or hybrids, the Ferrari 12Cilindri is all about the 6.5-liter V-12! The 6.5-liter, 65-degree unit is the latest evolution of Ferrari’s F140 V-12, first used in the Enzo two decades ago. Here, it makes 819 naturally aspirated horsepower at 9,250 rpm and 500 pound-feet of torque at 7,250 rpm, with redline set at a screaming 9,500 rpm. There’s no hybrid assist either—Ferrari has managed to meet all the relevant emissions standards without relying on electrification. Paired with the engine is an eight-speed dual-clutch gearbox mounted at the rear, which promises 30 percent quicker shifts than the 812’s transmission. Given the 812 was one of the quickest-shifting cars on the road, we can only imagine what this feels like. A switch to taller 21-inch tires effectively shortens the gear ratios by 5.0 percent, contributing to better acceleration. Ferrari quotes a 0-100 km/h time of 2.9 seconds and a 0-200 km/h time of less than 7.9 seconds. The Spider is barely slower, with acceleration times of 2.95 seconds and 8.2 seconds, respectively. Top speed for both is above 340 km/h. In terms of size, the 12Cilindri is slightly bigger than the 812 Superfast in most dimensions, though the wheelbase is an inch shorter. The design is similar to what we’ve seen with the Roma, with more technical detailing. The black panel ahead of the hood and between the lights references the plexiglass panel found on early examples of the 365 GTB/4 Daytona. Really, the whole thing is quite Daytona-esque. Inside, you get the now-traditional Ferrari steering wheel festooned with controls, but unlike a lot of new models from the brand, there’s a central infotainment display. Otherwise, the cabin isn’t too different from what we’ve seen in the Purosangue, minus the rear seats. As to be expected, the 12Cilindri gets all of Ferrari’s latest, ultra-advanced chassis control systems, including Side Slip Control 8, which is designed to more quickly estimate tire grip levels. There’s also the clever independent four-wheel steering system, which can steer the rear tires in opposite directions from one another. As mentioned earlier, wheel sizes are up from 20 to 21 inches with 275/35ZR21s up front and 315/35ZR21s out back. Buyers have a choice of Michelin Pilot Sport S 5 or Goodyear Eagle F1 Supersport tires.

This maybe a quite stupid question but...I changed to City Gas pipe supply after the renovation of our kitchen and now have a spare gas cylinder. Not sure though of how to dispose of it will it be possible or sell it back to Union or Solar Gas?

My Doblo 1.9 JTD (manufactured in 2005) cylinder head is damaged. Can anyone tell me where to get a second hand cylinder head?
-
I heard that porting your cylinder heads can increase performance - meaning to slightly deepen the cylinder heads and smoothen out all the factory machine marks during the manufacturing process. The only hand ported cars are Integra Type R and European sports cars like Ferrari. I read that it's relatively simple if you know how to remove the engine parts and you can do it yourself if have the tools, but usually would need bead blasting first as a preparation step. My question is - where can I get this done for good and cheap in sg?

Pls advise what is the "intake side of the cylinder head"? Can I request the mechanic to install the spark plug accordingly during servicing? The next time you are doing a tune-up on your ride, be sure to take note of this modification. By simply installing your plugs in a particular way, you will pick up roughly 1 whp, dyno proven time and time again. Index your spark plugs - The idea here is to "aim" the open end of the spark plug terminal (the gap) towards the intake side of the cylinder head. In order to accomplish this, simply mark on the plug a small line to indicate where this gap is. Proceed to install them as you normally would, except when the plug is hand-tight (that is, you've screwed it in without a ratchet as far as it'll go), use your ratchet to tighten the plug until the open end of the plug, faces the intake side of your cylinder head. Try to line up as best as you can. It may require buying 2 sets of spark plugs in order to do this, but hopefully you'll be able to do this the first time. Be careful with aluminum heads not to over tighten, as that could lead to a costly repair. That's it! -

If it's an engine with more than four cylinders, Volvo doesn't want it in its lineup. Within the next 10 years, the Swedish automaker plans to eliminate any engine options greater than four cylinders in an effort to reduce fuel consumption and C02 emissions. No more five- and six-cylinder mills. In their place, Volvo will employ three- and four-cylinder units in both gasoline and diesel form. The new engine family is called Volvo Environmental Architecture (VEA), and the automaker says the new powertrains will be nearly 200 pounds lighter than its current engines. In addition, the new mills will improve fuel economy by 35 percent. That will be an impressive boost, and Volvo believes it can accomplish this feat without a reduction in performance. The 1.5-liter three-cylinder and 2.0-liter four-cylinder engines will start to make their way into production models by 2013. By 2020, the entire lineup will be filled with them.

Last week went to a workshop to change my front brake pad cos sometime there will be like a groaning sound like those from heavy vehicle when i do a slow full left turn. But the mechanic said that my pads were still ok but discovered that my right wheel was not rotating as smooth as my left wheel at neutral gear. the mechanic adjusted something near my break pedal (donno what cos i cannot see) and use a mechanical clamp ( that work in the reverse direction) to force the cylinder back. any bros here had similar experience? is there such a thing as brake cylinder servicing? Thank you in advance.

Arguably more than any other automaker, Volkswagen has been the subject of much debate regarding a potential F1 program over the past year or two. The German industrial giant is one of the largest never to have competed in the pinnacle motorsport series. But while previous reports suggested that VW could partner with a specific team, the company's interests now seem to extend far beyond the classical engine-supplier

When Jaguar first introduced the XF here in the States, no one batted an eye when the car only came in V8 flavors. After all, a luxury sedan demands eight cylinders, right? Sort of. Skip across the Atlantic, and buyers have less interest in a fuel-swilling eight pot. Instead, the luxo-barges of the old country typically run smaller, more efficient diesel mills. Except in Jaguar's case, the company only offers a V6 oilburner in the XF line. Word has it that the big cat is out to fix the issue. Starting this fall, Europeans are likely to start seeing a twin-turbo 2.2-liter four-cylinder diesel engine crop up on the option sheet. The powerplant is being refitted from Land Rover Freelander (LR2) duty, but will feature quite a bit more power and a new start/stop system to help keep fuel consumption low. Will they bring it to the States? Sure, right after Michael Jackson rises from the grave to run as Sarah Palin's VP candidate for 2012.

I am thinking about this issue with cylinder walls lubrication and perhaps why 2T oil works for 4 stroke engines. We all know that most cars have 3 sets of piston rings. 2 for compression and 1 for oil. http://www.federalmogul.com/korihandbook/en/section_8.htm For more info about piston rings, check out the link above. I am thinking that when the piston moves down, the oil scrapper ring will remove most of the oil on the cylinder walls. This means there is very little oil left on the walls. When the piston moves up again, wouldn't there be metal-metal contact since the cylinder walls have hardly any oil? Pistons rings uses high wear resistance materials or coatings/plating (as shown in the link) proves that they do wear out and there is contact and lots of friction. IMHO, why 2T oil works is because when air/fuel mixture enters the combustion chamber, some of the fuel will cling onto the cylinder walls, hence creating a thin layer of lubrication. Hence reducing friction as the piston moves up. What do you guys think?

hi all, just wondering if anyone here has direct contacts to workshops that do skimming/machining of cylinder heads? I've got a Toyota Forklift cylinder head that is blown. I'm trying to find out the prices of a new head but I believe it'll be very expensive so I'm checking around to see if I can send it for machining. I believe most bros here sent the car to workshops where they will do the complete job, but unfortunately, I've only got a cylinder head on my hand right now. so it doesn't help me to go to those workshops..... once I get it machined, I'll get a slightly thicker gasket and I believe this should work ok for a few more good years for the forklift. Thanks for any advise here as well.

Man dies after homemade natural gas cylinder explodes Tank for fuel was placed under a seat in van and had originally been a cooking gas cylinder FATAL BLAST: The scene after the explosion at thepetrol station THE two brothers liked tinkering with gadgets and modifying them But last Friday, their hobby led to the death of one of them when a cooking gas cylinder they converted to store natural gas for their van exploded. Younger brother Mohd Hilmi Ishak, 25, was killed in the blast that occurred at 7.50pm at a petrol station in Batu Berendam, Malacca, reported Malaysian newspapers. The van, with Mr Hilmi, brother Mohd Rosli, 30, and a friend, Mr Razali Md Zin, 31, had pulled into the petrol station. They were filling up the cylinder, which Metro Ahad said was understood to have been under one of the front seats, when the blast occurred. It blew out the front portion of the van and two doors and shattered Mr Hilmi's left leg. His abdomen was ripped open. He was rushed to hospital, but was pronounced dead at 1.30am. The other two men had light injuries. The brothers run a family business dealing in second-hand electrical appliances. Mr Razali said they had been using the van for a month and had often travelled to Singapore and Johor in it. Spark caused blast The explosion is believed to have been caused by a spark from the engine, which was running while they were refuelling, New Straits Times reported. At the hospital, Mr Hilmi's father-in-law, Mr Zahmin Ibrahim, 50, told The Star that the victim and his daughter, Madam Nur Syahirah, 23, married about four months ago. He said his daughter, who is two months' pregnant, was devastated. 'We refused to allow her to come to the hospital as the loss would be too much for her to bear, as she is now pregnant,' he said. Road Transport Department director-general Solah Mat Hassan advised the public to use authorised workshops to install natural gas tanks. He said: 'Sometimes, people are taken in by the cheap conversions offered by irresponsible workshops. 'Some people also ignore the basic safety rules at petrol stations, like switching off the engine and their handphones.' Cooking cylinders too thin An authorised installer in Johor, known only as Mr Lai, told Nanyang Siang Pau that cooking gas cylinders are not suitable for natural gas because they are usually not as thick as natural gas cylinders. Datuk Solah said two similar incidents had been reported in Kuala Lumpur . Malacca Chief Minister Mohd Ali Rustam, who visited the survivors, urged the authorities to clamp down on those who illegally modify their vehicles. Sin Chew Daily reported that the brothers once turned second-hand washing machines into coin-operated ones so that the machines could be used at public places. Several schools in Malacca have benefited from the innovation.

An SG CNG user went to JB and forgot to lock his car. Came back and coin box was empty together with the cylinder from the boot. Electronics and injectors are still present. The JB thieves are damn hiong I must say. The cylinder weighs as much as a human being and pulling it out from the boot is hard. Remember to lock up.

Piped gas to cost more from Friday [/color] HOUSEHOLDS using piped gas will have to pay 1.87 cents per kWh from this Friday, which will add $1.70 to their monthly gas bill. City Gas, announcing the tariff increase, blames 'substantial increase in fuel oil price' as a reason for the hike. The current increase represents a 9.7 per cent hike from the current 19.34 cents per unit. Piped gas prices are reviewed quarterly to bring them in line with supply. The last hike was in February this year when tariffs went up by about 7 per cent. Natural gas price is pegged to that of high sulphur fuel oil (HSFO). The last revision saw the forward pricing of HSFO forecast at US$494.97 (S$872.41) per metric tonne. But the current forecast for HSFO for Aug 15 to Oct 31 is US$632.18 per metric tonne - an increase of 24.9 per cent since the February revision. So the general tariffs have been revised to 21.21 cents per unit, up from the current 19.34 cents per unit, which kicks in on Friday. City Gas supplies piped gas to 90 per cent of the residents living in new Housing Board estates and private properties, as well as commercial operations like hawker centres and hotels. http://www.straitstimes.com/Breaking%2BNew...ory_267662.html vs My house has been on piped gas since ages. How much does the latter cost nowadays??... And which one is cheaper if, say, cook meal for a family of six once a day (I think my present average monthly consumption is about $60/month)

Hey, I did this cylinder de-carbonizing today and wow it really works. Engine was smoother and when accelerating, the first 3 gears were pulling really strong. Basically its a really easy and cheap maintenances to DIY. WARNING: Do not stick the whole hose down and suck up the water too fast, you will blow your engine. For further infor how to do it pls look into this link provided by one of bobistheoilguy forumer. http://www.automotiveforums.com/vbulletin/...ad.php?t=283211

According to the latest news, the FIA mistakenly leaked McLaren/Ferrari secrets and the information became momentarily public. I quickly check the PDFs that I'd downloaded on Wed and was amazed that I have been holding the original AND the editied copies too. So the secrects in Ferrari and McLaren were leaked by the FIA and I think the following info is of some interesting fact that you all woul like to know.. Ferrari uses: 1)"double-rear master cylinder with a spring -
Anyone knows if the master brake cylinder stopper can affect or damage the master brake cylinder?

http://www.sgcarmart.com/new_cars/P10452.php# Exterior looks like the Honda Accord by Kah Motor. "The Inspire's V6 3.0-liter i-VTEC Engine features Honda's Variable Cylinder Management System, which switches between six-cylinder operation and three-cylinder operation depending on driving conditions. When the system determines, through analysis of factors such as vehicle speed, engine speed, and throttle opening, that the vehicle is at cruising speed, it idles the intake and exhaust valves for the rear bank of three cylinders and halts fuel injection to those cylinders. The idled cylinders remain sealed, reducing pumping losses due to engine respiration by approximately 65%. This enables the V6 3.0-liter engine to supply ample power with a fuel efficiency of 11.6 km/L, on par with the fuel economy of a 2.4-liter in-line 4-cylinder engine."

Yo ! Looks like GMDAT have replaced the previous big car Magnus with this new TOSCA model ! http://www.gmdat.com/kor/index.jsp Check out the all aluminium 6 cylinder engine both in the 2.0 and 2.5 litre form ! Looks and sounds great ! This engine should be very very smooth ! In the US, Chevrolet have named the previous Magnus as Epica ! Wonder if the same name would be used ? From the side, it sure looks like the new Sonata ! CBX

Back in the good old days when cars were all carburetted, one of the prefered way to enhance the performance is to do thing like valve polishing, valve seat adjusting, cylinder head surface polishing, port correction, boring and honing, etc, etc. This increase the enginee HP output by a big amount as the fit between moving parts are almost perfect and as a result little energy is lost to friction and heat build up. I wonder if this method is still being used today or has any one tried it.

Is this the future? http://www.canadiandriver.com/articles/jk/041014.htm Can big V6 and V8 monsters sip petrol like 4-bangers and still retain their monstrous torque without forced induction?

i know the compression ratio will increase after the head is skimmed, but how much can one skimmed without causing damage to the engine when running ??
