  1. In all honesty, I can see where she’s coming from. Just look at our articles. What happened? Singaporean influencer and Tiktoker Nicole Chang Min put out a scorching hot take about our local drivers on a Tiktok that has since garnered over 94,000 views. The Tiktok opens with Nicole exclaiming that Singaporean drivers “sux” , saying that when she signals she is going to change lane, they often speed up to prevent her overtaking. (sorry for the play button guys, icon won’t disappear no matter what) She proceeds to ask why drivers must always “zham” on the gas and overtake her, as if letting her overtake will result in their deaths. Online chatter Public opinion is split depending on where you came across this video. Tiktok is surprisingly sympathetic, with others coming with their agreements. However, Facebook users suspect it being Nicole’s own fault for not being a good enough driver (basically skill issue but even less polite), or the other sort of stereotype about a specific sort of driver… Writer’s thoughts - Probably not her fault, our other articles should serve as adequate evidence. ========= Be the first to get the latest road/ COE news and get first dibs on exclusive promos and giveaways in our Telegram SGCM Community.

  3. http://www.centuryperformance.com/heatwraps.asp Many times I've been asked about, or have commented on the use of header wraps. This issue is a real pet peeve of mine. Good or bad about a product I'll give my opinion based upon direct use and fact. THE FACTS: Header wraps are designed to keep the heat in the header to improve scavenging of the cylinders. Keeping the heat in the header allows the exhaust speed to remain high. (the right idea) There are no header manufacturers that I know of that will warranty their headers if any header wraps are installed on their products. In most cases the header wrap damages the headers beyond repair. (I will explain below) If you run a lean mixture, you "may" see a slim performance gain using header wraps. A rich mixture may show slim to absolutely NO gain in performance. If you do not mind replacing your headers and header gaskets regularly, and you like that ugly look of a wrapped header, go ahead and use the heat wrap. BACKGROUND INFORMATION: In the past, almost all NASCAR and other racing engine builders used the header wraps for the added power gains. But, after having to replace the headers after each race due to the wrap being about the only thing holding the header together, they do not promote the practice any longer! They now utilize the thermal coatings that are chemically and electrically applied to the headers. Those include Airborn, Jet Hot, HPC, and others. Imagine having to replace a $1200.00 plus set of headers after each race weekend! Few but the most financially well-off race teams can afford to do this. But, it is also in the downtime for remaking a custom set of headers. Most custom header makers do not have copies readily available. I believe that the wraps are good to protect various items from heat, but not to hold the heat in the header. For example: you can use the wrapping for the protection of fuel and oil lines, wiring, etc. Cool air needs to be around the header, and insulating it with a wrap to hold exhaust heat in makes the header material temperatures near molten. When you wrap the header you trap the heat in the header, but also in the material that needs to breathe to dissipate heat for it's own survival. Engineers, Metallurgists, and other experts out there will state that there is no way that the material can fail because it can withstand, and it was designed to withstand, the internal temperatures of exhaust gases. TRUE! But, when the header is not allowed to cool so as to dissipate those extreme temperatures that the wrap is controlling, you have now developed a heat absorption that compares to thermal friction which will will continue to gain in temperature beyond the normal exhaust gas temperatures (EGT's). This is the same as with most any insulation. Try this experiment ... launder a load of bath towels and then dry them. Immediately pull them out of the dryer and just toss them in a snug pile on your bed. Now leave them there for a day and then open them. You will find that there is still a considerable amount of heat left in the center towels. This heat, even though the outer towels and bed are normal room temperature have been able to contain their heat. This is a simple thermal insulation test, but with your headers you have an internal heat supply coming from the engine. The heat on the outside portion of the header material is trapped between the warp and the header and will continue to fatigue the header. This build of heat is amplified by the wrap. Towels do not need to breathe, header material does. The EGTs stay the same but the properties of the header material changes in a way of amplifying the temperatures because of the insulation. This action goes against normal laws of thermal dynamics, but this effect is fact, and you have to pull the ears off most engineers before they believe you. This is the trouble with plenty of education, but NO "common sense"! back to top Here are a few temperature readings taken at Daytona Motor Speedway. Below are the test parameters and results using Jet Hot® coated and uncoated headers: (10 Laps, same engine and car with identical headers, one standard, one Jet Hot® coated. Engine is ran between 6,900 and 7,500 RPM and temperatures are measured immediately after the last lap with the engine idling at 2,000 RPM with identical sustained EGT's of 850º.) MEASURED AT: Jet Hot Coated No Coating DIFFERENCE 1" from engine port (on header) 300º 750º 450º 2" above header 210º 300º 90º 1" above floor pan (in car) 115º 165º 50º Pretty impressive difference, and any of these coatings do not damage the headers, the coating becomes part of the header. Most of the other coating brands are comparable to these figures. back to top Something else that few Racers and Car Owners realize: Headers Oxidize! Under normal use and even more with higher EGTs and header surface temperatures, headers will oxidize and material is actually removed from the headers. This means they get lighter and weaker. Try these actual test numbers: Mild Steel (1010) uncoated header exposed to 1200º F. in normal air will have a weight loss percentage of roughly 25% with only 10 hours use at this temperature. Stainless Steel (410) uncoated header will have roughly 8% weight loss in the same 10 hour period. A coated mild steel header will have NO weight loss at temperatures up to 1200º F. In fact it will actually gain a bit of weight! Between 1300º F. and 1600º F. the coating will begin to show signs of mud cracking or like the look of lacquer checking. However, limited diffusion takes place between the coating and the substrate, producing a very thin film of iron aluminide, which continues to inhibit oxidation. Now, use the info above and then add the heat stress generated by the wraps. What do you see? Remember that the wrapped metal cannot cool properly and the header wrap is causing the material to super-heat and pre-maturely fail! back to top On A Side Note: Do you understand the physics of exhaust flow in regards to step-headers? Step headers are designed to allow controlled and efficient exhaust gas expansion at a selected engine RPM. What does this mean? As exhaust gases are exiting the engine into the header they are still burning and rapidly expanding down the primary tubes. If you design the header to take advantage of the pulse expansions of the exhaust gases you WILL gain horsepower. But, you'd better do it right, or that $1200.00 or more for a set of headers is a waste of money. When you set up a step header, you'd better know where you want the maximum power at, since steps are RPM specific to each engine combination. I'd better say this now ... a step is an increase in tube diameter. Here is an example: A basic Chevrolet 350 cubic inch engine ... 3.48 stroke, 5.7" connecting rod length, 4.0" bore, 10.5:1 compression ratio, standard 2.02 / 1.60 valves ... designed for 6500 RPM operation. Cam specs are: .500" lift, 235º duration @ .050" lift, 112º lobe centerline. For the average Joe Bracket Racer this would be a standard 1-5/8" or 1-3/4" primary header primary tube size, depending on vehicle weight and where you want your power. Here is the "exact" header size for a racing engine operating at 6500 RPM. Note: This is for max power at 6500 RPM! HEADER TYPE PRIMARY TUBE DIAMETER PRIMARY STEP LENGTH SECOND STEP DIAMETER SECOND STEP LENGTH THIRD STEP DIAMETER THIRD STEP LENGTH Straight pipe 1.757" 31.9" - 34.4" 2-Step header 1.757 " 14.0" - 16.5" 1.882" 15.4" - 17.9" 3-Step header 1.632" 14.0" - 16.5" 1.757" 6.8" - 9.3" 1.882" 6.1" - 8.6" Collector Specs: 3.221" Diameter with a 18-23" length (2nd best = 9-11.5" length) Acoustical Tuning Specs: best wave = (- negative pressure) = 5,000 - 6,000 RPMs bad wave = (+ positive pressure) = 2,018 - 3,518 RPMs wav-lag degrees = 3.2º - 6.3º This is a "Optimized" header design for an engine operating primarily at 6500 peak horsepower operation. The reason for adding the above step-header specs was to to let you know that the header has areas that the expansive exhaust gases compress as they pass through the header. Or should I say the gases are not allowed to expand. As we all know, compression of air, or in this case exhaust gases, you will generate heat. Anywhere there is not the proper step you will get added heat. Of course there is no "Perfect" header design unless the engine was to never change RPM. With an engine that has operating use from idle to well over 6,000, 8,000 or even 10,000 RPM, there is no specific header that is best for an entire power band. You set up the step header for the RPM that the engine will spend the most operating time. You can call this compression of exhaust gases (or restriction) that of thermal dynamic friction. You cannot have true friction from a gas against a solid, but you can have this compressed gas as a source of added exhaust heat. back to top BASIC KNOWLEDGE: As you may or may not know from any education of standard thermal expansion physics, if you heat donut does it shrink or expand the hole? Of course since we live in a 3-dimensional world, it is a 3-dimensional reaction and it shrinks the hole! If any engineers want to argue this, start with your professors, not with me. I already know the facts and I have had engineering "students" argue this fact with me on numerous occasions. Because of the expanding gases, if you have had the experience (as I have) to see first hand where a header with a wrap fails, it is typically where a step would be. I have had headers in my hand where literally the only thing keeping the header in one piece was the wrap. Whole chunks of the header material was gone, melted away. Talk to most "engineers" (I use that title with caution) and they will probably tell you that aliens stole the metal as the car was racing around the track! They say this because the wrap is causing problems that are not part of normal metallurgy and thermal dynamics theory . The header warp allows temperatures between the wrap and the header to turn the material molten. back to top IN CLOSING: We know that header manufacturers will NOT WARRANTY a header which has had a wrap installed on it. We know that I have personally seen, tested and inspected headers that have been destroyed after running wrapped headers on a perfectly tuned engine. Just because an item or product is advertised for a specific use does not mean it does not do what it is promoted as, but it also does not mean it is the best choice either. We have all seen the recent TV commercials on all of these "medical miracles" that do such feats as fast weight loss and re-grow your hair. How often have we laughed at the side affects, like the most common being penile failure. Oh sure, I want to take some drug if my hair starts falling out (yes, it is currently all here) that makes my sex life go to hell. NOT !!! Those pharmaceutical companies can pucker up and kiss my "bald" backside! I'd rather have function than hair. The same can hold true with other products. Heat wraps are great, just do not use them ON the header. Use them on a device or component on your vehicle that you are trying to protect from header heat. If you want a true thermal barrier that will reduce thermal loss in the header, reduce under hood temperatures, and make a few horsepower in the process, have your headers coated by one of the many companies available (links to a few are above). Most all of the coating companies offer inside and outside complete coating as standard. DO NOT allow your headers to only be coated on the outside, this is not a complete or quality process. Some other considerations about the coatings. Once the header is coated, it's permanent. That means that if you screw up your header, it is not an ease job to repair and most header companies do not want to even attempt a repair. The coating permeates into the header material which makes welding processes on a coated material less than adequate. This is why you always coat the headers last, after all modifications to the header are made, and you are 100% sure the header will fit your vehicle.

  6. Saw this blog post - and I totally agree with the writer. Singapore drivers suck! http://onswipe.com/poachedmag/#!/entry...7fc7b5670548f1f
  7. http://www.straitstimes.com/STForum/...ry_742941.html AS ITS designation states, the certificate of entitlement (COE) is an entitlement and assumes that as every person feels he is entitled to it, a price must be levied to show that one truly needs it ('COE domination by high-end marque buyers an unhealthy trend' by Mr Johnnie Chia; Wednesday). In a meritocracy like Singapore, one earns more if one works harder and smarter than the other person. If an average-income earner wants a car badly, he will have to lift himself to a higher income bracket by working harder or smarter. That is the COE's first benefit: as a spur to improving one's lot in order to secure a car. Except for the peak-hour crunch, public transport is first-class. Without the COE, the roads would be clogged, and this is the COE's second benefit: freeing roads for efficient public transport commuting. Mr Chia laments that stiff COE prices favour the wealthy, who can afford to buy more than one car. What is also true is that a rich person can drive only one car at a time, so the second car is kept at home, and is not out on the streets causing pollution. And that is the third benefit: fewer cars, less pollution. Furthermore, the wealthy person pays a hefty premium to own a car he keeps in his garage and we should be thankful for his tax contribution: It helps pay for public conveniences. My point is, one should always consider both sides of an issue. When a person is wealthy and drives a Ferrari and is busy forging deals, he will be only too happy to have an Electronic Road Pricing system in place, so he can zip around and close another productive deal - and pay the salaries of his average-income employees. That's life.

  8. Typically don't really like to post about bad drivers as it is part and parcel of driving, but yesterday a red Kia Rio (SFF 54__ K) nearly got into an accident with me at Commonwealth Ave West junction of Clementi Ave 6. Here is a view of the said junction :- 2 lanes going straight, 2 lanes turning right. However, opposite the junction, there are 3 lanes, although lane 1 is marked with chevron markings. And this is what happened :- (not actual footage (this is from google maps) but can already see another dude driving over the chevrons ) The Kia decided to go straight even though he was in the wrong lane before the junction.. OK FINE. I understand because sometimes you can be caught in the wrong lane due to heavy traffic. BUT at least go straight into Lane 1 and drive over the chevrons instead of trying to merge into my lane!! Our two cars combined doesn't form Devastator ok... this is not Transformers. This is not the first time and in fact 50% of the time I drive past Clementi during rush hour, there will be some kok driver pulling some stunt or another. Just hope drivers try to keep to the 2 left lanes early if they are going straight towards Jurong. And if you are really in the wrong lane, use the chevron lane to go straight. Already committing a violation then suddenly want to be legal again? lol And no KIA bashing please

  10. We all know a car sucks a lot of money. A regular car can easily cost us $1500 a month. A nicer car >$2000. Most of this money is irrecoverable and we are essentially renting a car despite our illusions of ownership. We would be considered lucky we dont have to top up the finance company just to sell away our cars! If instead of having a car, we put the same $ in any investment over the years, I think most of us would be rich! (Yeah we all know who is the blood sucking benifactor ). Eg 1.5k a month =18k a year or $180k in 10 years!!!! Yet they are thinking of charging us more for our cars! So how much does your car suck from you every month in terms of percentage of your net income or take home pay? Net income is what you get after CPF deductions.
  11. Hi Guys I just had my Swift on 31/8/07 and had clocked abt 7K so far. Alhough my servicing for 3 years are labour cost free, they are charging me $60 for mineral oil + filter and $95 for syntectic oil + filter. So I asked if I could bring my own instead, the person told me that they will charge me $20 for the labour fee. I am puzzled. Wasnt it supposed to be labour fee free?
  12. This is to advice bros who sent their car back to Tan Cheong(ubi) to double check that what repair that is printed on the job sheet is been done and to confirmed that they really change the part that is stated. Last year, when car still under warranty, complain that my shock absorber got problem, so they (TC ubi) checked, and change the back left shock, but drive for one or two weeks found there is not much improvement, complain again and they change the back right shock, after that again the same thing happen, like my car got no shock absorber like that, going over hump like it bottoms out. Thought that the car is design this way, blame fate that I bought this car, But continue to drive for another few month until I cannot stand it, bring the car to a workshop and boss confirm that the shock spoil, change to a set of Koni and the problem solve.

  13. i was caught in flood....CAI suck in water....engine stalled....i tired to push start a few times...but didn't managed to start...now my car is being towed to workshop...can anyone advise me what will the damage on my car be and also what should i do....
  14. My stock air box have been changed to simota open pod + CAI. Ytd was travelling on the road, raining v heavily, saw a big puddle of water in the front, scared car might aquaplane and skid, thus drop gear and went pass it. the moment i went thru it, car jerked, and rpm going up and down with no sequence, thus signal left and slow down, prepare to stop, when about to come to a stop, car engine died. restart again and revolve the engine, ropm goin up and down, not smooth and engine vibrating. off engine and waitied for 5 mins and everything seems fine. problem is engine dun seems smooth as before. wad i suspect is my air filter suck in water which makes the engine behave this way. but would like to know wad are the damages to the car, cos i heard engine sucking ion water could be quite a big problem. car is due for servicing in 1000km, was thinking to send it in now for a engine flush and ask them to diagnose to see if theres any problem, but wad can i say to tell them that engine did dies, and not let them know i did modify my air box, intend to put back everything to stock b4 goin in. car is Nissan sunny N16
  15. please read today's "the sunday times". the car dealers make big money when they sell each car. especially Toyota cars. even the "Vios" also get Gross profit $14k. No wonder so samll market in singpore, but has so many car dealers.
