  1. When I accelerate my Lancer up to and beyond 80km/h, the "womming" noise can be heard from the front & seem to be from the engine compartment. When the speed reach 100km/h & beyond, the noise get louder. Can anyone enlighten me on what could be the problem with my car. Thanks
  2. I believe most people are not aware of the relationship between air pressure and load index when replacing their tires. Me too... source: http://www.tirereview.com/?type=art&id=5278& Double Jeopardy by Scott Blair In March 2006 / In Focus: Performance When you sell a set of non-OE tires, do you set the air pressure the same as it was in the OE tires? Do your sales staff, manager and technicians understand the importance of load index? Can they read a load and inflation table? Can they recite, from memory, the inflation rule – that the replacement tire must meet or exceed the OE tire’s load carrying capacity? If the answer’s “no,” you might be taking a big liability risk. Not only do you have to train your staff in these matters, you also have to document that training to be fully protected against potential legal losses. Concerned? You should be. In fact, sit down and hold on; we’re going to hit you right between the eyes. We’re going to show you how you can sell the right tire size but the wrong load index. More Complex Than Ever Times have changed. Five years ago, a specific tire size had only one load index number. Not today. Now, a given tire size may have as many as five different load index numbers molded on the sidewall, making it impossible just to look at the size of a given tire and make the assumption that the load index number is the same just because the tire size is same. These days, you have to look at each tire, along with its complete sizing information, before you can make any fitment decisions. The following case studies will illustrate the importance of the relationship between load index and tire size. Case File: One A customer wants a set of 20-inch tires on his 2003 Lexus LS430. The OE tire is a P225/55R17 95H, standard load (SL) with a load index of 95 and recommended cold inflation pressure of 32 psi front/rear. The overall diameter (OD) is 26.8. You have a stack of P255/35R20 93Hs on the floor with an OD of 27, so you sell him a package deal. “The OD is correct, so it must the right tire,” you think to yourself. Not so fast. Take a look at the load index of that 20-inch tire. Notice that it is 93. The OE tire’s load index was 95. Install that tire, and you just might open the door to a liability suit if that customer gets into a wreck after leaving your shop. “How can this be?” you ask. I’ll show you: The OE P225/55R17 95H tire inflated to the recommended air pressure equates to 1,477 pounds of load capacity. A standard load (SL) P-metric tire reaches its maximum load capacity at 35 psi, regardless of the maximum inflation pressure listed on the sidewall! Looking at the load and inflation table, we see that the load index of 93 on the P255/35R20 93H tire equates to only 1,433 pounds of load capacity at 35 psi. It’s only 44 pounds per tire. “That’s not going to matter,” you argue. Tell that to the judge when he reads a settlement against you for some ridiculous amount of money because “the replacement tire did not meet or exceed the OE tire’s load carrying capacity.” The correct tire for this plus-size application should be a euro-metric (There is a difference!) 255/35R20 97H XL (extra load) tire, which has a load index of 97. Let’s say you installed this tire, which we now know is correct, but you used the OE air pressure of 32 psi. At 32 psi, this tire will only carry 1,290 pounds. If you do the math, you’ll see the following: 1,477-1,290=187 pounds overloaded per tire or 748 pounds totally overloaded. The correct cold inflation pressure should be adjusted to 38 psi front/rear to equal the 1,477 pounds of load capacity specified by the vehicle manufacturer. Case File: Two A customer comes in and wants a set of 20-inch tires on a 2004 Dodge Ram 1500 SLT Crew Cab RWD truck. The OE tire is a P265/70R17 113R (SL), with a recommended cold inflation pressure of 35 psi front/rear. You have a set of take-offs from another Ram 1500 already mounted with P275/55R20 111S tires. Since they came off of a Ram 1500, they should fit your customer’s truck, right? Sure, they might ‘fit,’ but they won’t be the right tires. The OE tire inflated to 35 psi equates to 2,535 pounds of load capacity. Take a look at the 20-inch tire’s load index: 111 SL. As mentioned earlier, a (SL) P-metric tire reaches its maximum load capacity at 35 psi. Therefore, a lower load index will decrease the maximum load capacity. If you were to install this tire and inflate it to 35 psi, the tire would be overloaded by 132 (2,535-2,403) pounds per tire or 528 pounds totally overloaded. The correct tire would be the optional tire that Dodge uses on its heavier trucks – P275/60R20 114S (SL). The load and inflation table reveals that, with the higher load index, we can adjust air pressure to 33 psi and still meet the OE recommended cold inflation pressure. In this case, however, you should still inflate to 35 psi, which exceeds the minimum recommended load capacity. The load capacity numbers were not technically correct. Can you guess why? Notice that, in Case One, a P-metric tire was installed on a light truck. According to the RMA, the load capacity of a P-metric or euro-metric tire installed on a light truck has to be reduced. Divide the load capacity of the P-metric or euro-metric tire by 1.1 to determine the load capacity for a light truck application. A common example would be a P235/75R15 105S (SL) tire inflated to 35 psi. The load capacity for a passenger car application would be 2,028 pounds. Placing this same tire on a light truck equates to 1,844 (2028
  3. I was wondering how to hook up a sub if you have one or two voice coils, and how it affects the impedance, which of course determines what kind of amp you should be looking for. This website shows you the various wiring options and the effect on the impedance the amp sees: This is the 1sub 4ohm 2 voice coil model: http://www.hifisoundconnection.com/How-to-Wire-One-Dual-4-Ohm-Voice-Coil-Subwoofer You can play with the options and see what suits you best.

  5. for my cars usually when it is time for a change of batt, i will change to an oversized one. because my cars are usually underutilized and i ever been overseas for up to 2 mths. after 2 months, the car still start up fine !!!! One of the mechanic ever told me before, that the car's alternator is not a "smart" charger. there is no tickle-charge when the batt is almost full or it doesn't stop charging even when it is full. the load on the alternator is constant. anybody knows or can share his knowledge on this topic?
  6. I have some friends who are not sure of what kind of tyres that they should get. Some even got con by roadside tyre shop. Hope this will help. Example of your tyre 205/65R15 95H 1 - (175) Nominal Tyre Width (mm) It is the nominal width in millimeters of the tyre inflated and mounted and on the rim specified in the standard. The nominal rim width may not be identical to the actual measured width of the tyre. 2 - (70) Aspect ratio: It is the ratio of the tyre section height to tyre width. As the aspect ratio decreases, the tyre section height (sidewall height) becomes smaller. 3 - ® Radial Tyre 4 - (13) Rim Diameter 5 - (82) Load Index: It refers to the maximum load that the tyre can carry at the rated speed. The load index is a numerical code associated with the maximum load a tyre can carry at the speed indicated by its speed symbol. Load Index/ Max Load/tyre(kg) 81/462kg 82/475kg 85/515kg 86/530kg 87/545kg 90/600kg 92/630kg 95/690kg 96/710kg Speed Rating Speed (Km/h) S 180 T 190 U 200 H 210 V 240 W 270 Y 300 VR 210+ ZR 240+

  8. ESPN Latest : New rules force Man City to sell 12 players Manchester City will have to offload around 12 players before the transfer window closes at the end of next month - otherwise they will be left with players they are unable to play. New Premier League rules state that a club must submit a squad of 25 players on September 1, and only those players will be eligible to be named in a matchday squad. Clubs can supplement that list with an unlimited number of players aged 21 or under, but in Manchester City's case they are currently well over the 25-man limit. Players such as Roque Santa Cruz, Craig Bellamy, Jo, Felipe Caicedo, Micah Richards, Michael Johnson, Vincent Kompany, Shaun Wright-Phillips, Stephen Ireland, Nigel De Jong, Kelvin Etuhu, Pablo Zabaleta and Nedum Onuoha could find themselves out in the cold if they are still at Eastlands when the transfer window closes. Robinho is also officially still a City player. And City could be forced to accept reduced fees for these players as rival clubs look to take advantage of their situation. Sh*t, none can fit into Liverpool ................. if not, can get plenty of discounted players from ManCity ......
  9. Ed Gorman I was doing some research, at a fast pace, it has to be said, into last year's race in Singapore and I came across the official Renault press release from that Grand Prix. I am surprised I had not stumbled across it before because it is a pretty smelly document all round. It reminds us that Briatore, Symonds and Piquet not only deceived motor racing fans the world over that night but also the vast majority of their own team who genuinely thought they had won a race against all odds. P1020273 The press release is worth quoting from because it sums up what a shabby and disgraceful episode this was. The fiction that it contains, by the way, is presented alongside the corporate brand images of 26 commercial sponsors of Renault's Formula One team, among them ING, Mutua Madrilena, Elf and Universa. I am sure they are delighted about that... The document starts as follows: Singapore Grand Prix, Sunday "The ING Renault F1 took its first victory of the season today as Fernando Alonso produced a brilliant tactical drive to win the Singapore Grand Prix, the sport's first ever night race." And here are the quotes from the key players that night, three of whom knew about a conspiracy to cheat, one of whom has said he did not. It starts with the latter - the race winner. Fernando Alonso P1 "This is a fantastic result - my first podium of the season; my first victory and I'm very happy, although I think it will take several days for me to realise what we have achieved. Winning a Grand Prix here just seemed to be impossible because we missed our chance yesterday in qualifying, but we were very fortunate today and it's a superb result for the team. We chose an aggressive strategy and we had a bit of luck, but we had the pace and the car was fantastic throughout the weekend." Nelson Piquet DNF "From the start of the race things were complicated and I had a lot of graining and the situation got worse and worse. The team asked me to push, which I tried to do and finally I lost the rear of my car. I hit the wall heavily but I'm ok. I am disappointed with my race but obviously very happy for the team this evening." Flavio Briatore, Managing Director ING Renault F1 Team "This is an amazing victory for Renault and for Fernando. Since Friday we knew that the car was very competitive and we were very disappointed at the end of qualifying. Today the car was extremely quick, stronger than Ferrari and McLaren, and although we had some luck when the safety car came out, we deserved this victory. It's a very important result for Renault after two difficult seasons and that helps us to prepare for 2009 in the best way possible." Pat Symonds, Executive Director of Engineering "I think the luck we had in the early part of the race was nearly a cancellation of the bad luck we had yesterday. The car has proven itself and so has Fernando. The whole result is a tribute to the team and this wonderful circuit is a tribute to Singapore." I have resisted the temptation to annotate or add exclamation marks. A "brilliant tactical drive", things were "complicated" a "deserved" victory, a "tribute" to the team? I imagine there must have been one or two people on the plane home from that race who felt absolutely sick to their stomach. On that night I was far too naive to suspect that Renault could have fixed the whole thing. I remember hearing people discussing it and dismissed it immediately. I just could not accept, for a moment, that a team would risk its driver or risk its reputation in that way or sink that low. But I was wrong. Some of my colleagues were not so sceptical and among the most prescient was the veteran Joe Saward who dealt with potentially explosive and legally sensitive material cleverly in his race report. Have a look here, it makes interesting reading.

  13. Dumb

    Floor load

    [inline Renovation.jpg] Will a 3 ft fish tank with stand and all, including a 2 feet fish tank on the bottom shelf weight more than 150 kg? What can happen if a person or two stand within that square meter of floor space with the fish tanks.
  14. Further to this thread. Part 1 Hope the following is also helpful.
  15. Hi Guys, 1. When shopping for rims and tyres, have you ever consider those Max load numbers on the rims and tyres? 2. For example, if a rim max load is 550Kg and the tyre is 660Kg, what does it mean to us? Should their weight be equal to each other to begin with? Kindly advise. Thank you very much. Regards,
  16. Just wondering if this is possible. this phone comes default with the Route 66 that is not too detailed for local map usage.
  17. jus curious... ;) would it spoilt the engine if go often?
  18. Just another thought that I am thinking about. Most car is adequately powered w/o the air con switched on. However, once the air con is switched on, the power drop big time ! Am just curious, why didn't the car manufacturer EVER thought of balancing the torque/power to that with the air con switched on during the design ? I know certain countries dun use aircon when weather is cool, but they still have summer rite ? Just curious
  19. Hey all, My car boot is usually packed full with LOTS of "rubbish".... It's advisable?? I heard that the extra heavy loading is very bad for the car suspension. Can anyone please comment?
