Lesser powered car wins against a more powerful one? Ask Rob About Cars

Ask Rob About Cars | Examiner.com http://www.examiner.com/article/biggermotorlosttosmallermotoraskrobaboutcars 1/5 LEISURE / AUTOS & MOTORCYCLES / CAR & TRUCK ENTHUSIASTS Lesser powered car wins against a more powerful one? Ask Rob About Cars May 28, 2012 12:14 AM MST Hi Rob, I have a 2.0 liter car and I raced a 1.6 liter car but I lost the race. Can you please tell me what are the reasons that can lead to the loss? And how can I win in a race like this? Thanks, Bilal, Eqypt _____ Hello Bilal, Drag racing should be on the track and the start or "launch" is very important. Rob Eckaus, San Jose Cars Examiner 7/3/2016 Lesser powered car wins against a more powerful one? Ask Rob About Cars | Examiner.com http://www.examiner.com/article/biggermotorlosttosmallermotoraskrobaboutcars 2/5 Can you provide more details about the cars? There are many, many factors to consider besides engine size. First I have to discourage street racing but the situation and answers can certainly occur on any given dragstrip. As far as the car, engine size does not equal more horsepower unless built to take advantage of that size due to possible differences such as forced induction, cylinder heads, carburetor size, camshaft, compression ratio and emissions equipment. So without further details, it's absolutely possible a 1.6 liter can beat a 2.0 liter car. Thank you, Rob _________________ Hi again Rob, I've got some details about the cars I hope they can help. the first car is the one that lost the race. first car ( A620 ) second car ( A113 ) displacement(cc) 1997 1297 HP 124/6000rpm 82/6000rpm transmission 4 speed automatic 5 speed manual overall length(mm) 4770 3700 overall width(mm) 1815 1578 overall height(mm) 1445 1527 gross vehicle weight(kg) 1835 1415 no. of passengers 5 5 maximum speed(km/h) 175 156 Not that I encourage street racing but I was surprised when it happened and I want to understand how come it happened. If the problem is in the car, what may the problem be and what are the possible solutions to fix this problem? 7/3/2016 Lesser powered car wins against a more powerful one?

Thank you, Bilal _____ Hello Bilal, That information certainly explains it. If in fact your car is 1835kg, the power to weight ratio made all the difference. The other car is roughly 900lbs or 408kg lighter than yours, assuming equal passenger weight. You would need approximately 40 to 50hp more than what you have now to run close, tie or beat him. To add that much more power, the cheapest way is nitrous oxide, but I don't recommend it in your situation either. After that is forced induction or other major engine modifications. It can get very expensive. Secondly, the top speed, engine horsepower and transmissions tell me that these are not performance cars and have no business racing with any type of extra passenger weight in the car. Also, your car, being a 4speed automatic, probably can't select and hold a gear which gives the 5speed manual car a distinct advantage and probably has better gearing for acceleration. Taking significant weight out of a vehicle, unless dedicated for the track, basically makes it a junker, or an expensive proposition, so don't bother. As far as driver differences, knowing the launch characteristics of your car, available traction, gearing and reaction time/shifting are all factors. It takes practice and experience to learn and optimize your technique to account for those variables. Thank you so much for writing. Some things to keep in mind for the future: Never engage in high-risk behavior in a vehicle, especially when you have passengers or near other traffic. Also, your tires and brakes must be a match for the speeds you demand of your vehicle as well.

Sixth generation Camaro V6 review

Chevrolet updated the chassis of the Camaro for 2016 with the new Alpha platform and by all accounts the approximately 250 to 300lb weight reduction was a huge improvement. Despite having a brilliant chassis and three powerful engine choices, the interior and outward visibility hardly improved at all. I wanted to like this car, I really did. It has some really good aspects but overall it’s only good for going in a straight line, not reverse or backing up out of any parking space, on public roads or modified into a track-only car.  You decide if the interior justifies a $29,000 MSRP. The 2017 model is essentially the same. The 335hp V-6 is a great engine, responsive, sounds good and with the quick shifting 8 speed automatic, the car is capable of mid-high 13 second quarter mile ETs. It feels every bit as quick as the numbers suggest. It has no appreciable dead spots and has an excellent pull. The 8 speed auto is finicky on the highway though, downshifting at the slightest provocatio...

Nissan GT-R Review and Test Drive: Part 1 of 2

Click here for Part 2 of 2: Driving the Beast There were quite a few surprises driving the awesome and controversial Nissan GT-R. Having the opportunity to drive one on a twisty mountain road favored by motorcyclists was a thrill. It’s very “mechanical”, quite large and my impression more of a competitor to the Audi R8 than the Porsche 911 Twin Turbo. Background: This 2010 model has about 2000 miles on it. The MSRP was over $80,000. It features a 6-speed dual clutch paddle-shift rear transaxle. The 3.8 liter twin-turbo V-6 produces 485 hp at 6400rpm and 434 ft. lbs of torque at 3200 rpm. Known for consistent deep 3-second 0-60mph blasts and high 11-second quarter mile times, the biggest controversy was the factory reported Nurburgring time of 7:29, beating far lighter, 600 hp plus cars like the Porsche Carrera GT and Pagani Zonda F. The owner has had some notable cars in the past and is no stranger to track days. Cars like a track prepped Acura NSX, two E46 BMW M3s, and an ’04 Porsche ...

Multiple special guests are scheduled throughout the week such as local sports mascots, the Raiderettes, radio and television personality Gary Radnich and more. The Auto Salon which featured modified cars, trendsetters in an eclectic collection. It is in the south hall on the upper level. The signage needs to be increased, but it’s worth a visit. Yes, there were the broken-axle appearing stanced cars and plenty of lowered sedans, but there are some gems as well. Photography is a bit of a challenge due to the cars being too close together, but it’s a...
