Dyno Tuning Melbourne – What’s more important – Power or Torque?
We call it area under the graph. Now, what that means is, if you have a power line going up to 200KW or 300KW, and a torque line that’s, lets say, 500NM of torque, if you can increase the area under that torque graph, then generally, you will have increased in power.
Now, what that means is. If I can bring that torque line up from 500NM to 600NM, and not necessarily have an increase in power, that car is going to feel like a different car on the road, as it will have more pulling power at lower RPM, even though the actual peak power number is no greater than it was before the torque in the lower RPMs was increased.
So, in my eyes, I believe torque is more important than power.
There are people who like to see a high power number. They like to see the big figures. That’s great, but, to drive them at that top-end, at maximum RPM, at wide open throttle, the car is never going to get there on the road.
So, torque is more applicable to 99% of people on the road.
On a racetrack, torque is very important too, because when you are going into a corner and out of a corner, torque is the thing that actually gives you the pull. So torque is going to pull you out of the corner faster.
If you ask me what’s more important, power or torque. I would say to you, torque would be more important than power.
Having said that, you can’t have a power figure without a torque figure, so, if you increase the torque an engine is producing, you will have an increase in power in those same RPM areas.

When wiring up a car, or wiring in an ECU, one of the most important aspects, is good wiring.
Now, everyone thinks of wiring as being a good 12V power supply – “I must have a good 12V. I’ve run really thick battery leads”. It’s not the only thing.
There are two sources to power supply. You’ve got a ground, and you’ve got power.
Let’s take an injector for instance. That has power, and it has ground to operate it. An ECU will ground the pin of the injector to open it.
If you are wide open throttle running down the drag strip, and you have a bad ground supply to the ECU, then that will have a bad ground supply to the injector. That can lead to leaning an engine out, and even causing an engine blow up.
To ensure this doesn’t happen, you need to make sure all of the ground points on your engine are in really good condition and good spots.
On and OEM factory car, they often have about 4 different ground points. They have one at the front of the engine, one at the back of the engine, they generally have one down on the side of the motor, and one that goes from the alternator bracket to the battery.
These are all critical to the way an engine runs. Whether it’s to ground injectors, or ignition coils that need to be grounded to give good spark, once again, if you don’t have good ground for your ignition system, you’re not going to have a good spark, it’s going to break down under load when the engine is trying to produce maximum power.
Auto Parts Fast Features High Quality Parts to Improve Your Honda’s Fuel Mileage
We can’t deny it; we all need cars for us to live life normally everyday. Even if we have to go back to the basics to cut high costs of living, we cant really do without cars. They have become necessities in life through the years. However, some vehicles are harder to maintain and consumes more fuel; thus for some, they are pain in the neck—and the pocket—rather than helpful driving machines. But don’t worry, there are many ways to improve gas mileage; though you may have to replace some of your stock auto parts.
, one of the country’s top auto parts dealers features the best quality replacement and aftermarket parts, which can help you solve gas mileage problems. If you are particularly looking for , you can find here a comprehensive line of premium quality Honda engine parts, Honda cooling system parts, Honda body parts and Honda performance parts that can enhance not only your fuel economy but can also help you reduce harmful emissions and significantly improve performance.
The first thing you can do to improve fuel economy is to check on your engine. Make sure your engine is receiving enough air for the combustion and for its cooling. If it is not able to breathe in more air, replace filter or use bigger throttle body and premium quality performance intake manifold. Likewise, check on the way your engine exhales through the exhaust system. You should use a high-flow muffler to boost the car’s performance as well as to improve fuel mileage.
Like other exhaust system parts of your Honda, the improves performance and fuel mileage too as it converts gaseous wastes produced after the combustion into less harmful emissions. A clogged cat prevents exhaust gases from flowing smoothly out of the engine; thus, it won’t be able to clean them properly. This in effect would require the engine to work harder thus, more fuel is consumed. If you’re starting to smell something like rotten eggs, you already need to replace your Honda catalytic converter.
If you are in need of Honda catalytic converters, you can shop at , your most trusted online dealer of millions of top quality auto parts. You can find here high-flow catalytic converters for Honda Accord sedan, Honda Accord coupe, Honda Civic, Honda CR-V and other Honda models for just about half the original price.
Improving the aerodynamics of your car can also help you reduce fuel consumption. Race cars are usually fitted with spoilers and ground effects to improve aerodynamics and thus, its acceleration and fuel economy. You can also add a Honda spoiler on your car to help reduce wind resistance; however, this is more effective when applied to race cars. However, you can also replace your , , and other body panels with lighter auto parts. Aside from giving your car a new look, swapping hoods and other body parts can help your vehicle run more smoothly and faster. A Honda hood with rear-facing scoop would be a good alternative, too.
Another way to improve gas mileage is by replacing your worn out and tires. The tires may be particularly running low and thus they need to be aired up sufficiently. Lastly, make sure your engine is cooled properly so it can work more efficiently. You can replace or add auxiliary Honda radiator fan for more efficient cooling of the engine.

Aside from Honda parts, the store offers top of the line and a lot more. Fast, complete and secure, this auto parts store is the perfect solution to your fuel mileage problems.
But let’s take a moment to look at the fundamentals of the oil market. Supply is good. Inventory levels are very good. Demand worldwide is a little soft right now with the crisis in Japan. So why are fuel prices going up? Why are we all paying so darn much for fueling our fleet and personal vehicles? Heck, my wife said to me the other day, “I was going to get premium gas because the car engine was making a knocking sound, but there was no way I was going to pay over .00 a gallon!” Instead she got what she normally does, regular, paid .65 and her new car is still knocking.
I believe personal and fleet fueling costs are going up because of FEAR! FEAR! FEAR! Everyone is scared of the unknown. What if all this turmoil continues in the Middle East? Yes, the situation in Middle East is a mess and as I just wrote in my column, it has been a mess for a long time and will probably continue to be a mess for the foreseeable future. What if the U.S. and global economies continue to grow and there is a greater demand for oil? Yes, let’s hope the economies improve. And yes, the world’s energy demands will continue to increase and so will demand for crude oil. Even with natural gas, nuclear, clean coal, solar and electricity we are dependant on crude oil as the biggest source of energy.
Well, what if? What if? What if? My whole life I’ve played the tiresome and very complex game of asking myself “What if?” Lately, I have tried to stop, but I can’t just yet. How about this…what if we all just said ‘NO!’ to ‘what ifs?’ Just for a moment, let’s deal with the real facts on the table. Get rid of fear and not speculate about what might happen tomorrow. Truth is we have a good supply and we have good inventory, therefore diesel fuel prices should be .30 a gallon, gas prices should be .10 a gallon and crude oil should be around – a barrel.
Let’s look at some more facts. Do you know who makes more crude oil than anyone else in the world? Saudi Arabia. How much? Just under 20% of the world oil. Do you know what the Saudis believe the price of crude oil should be? – a barrel. Do you know who is the second largest crude oil producer? Oh Canada we love you! The Canadians are pumping out 13% of the world oil. Add the two together for 33% or one third of the world oil. Iraq is number four on the list with 9% of the world oil, followed by Kuwait at number five. Put them all together and that is almost 50% of the world oil right there.
Oil is the lifeblood for most of the oil producing countries that I did not mention here who make up the other 50% of world oil. It’s not in their best interest to cut off supply or price themselves out of the marketplace. That would be like shooting themselves in the foot.
However, it is unfortunate that fear is the reality right now. And even though I’m thinking prices are going to come down by the end of the month, followed by another drop in May, that won’t be the situation for too long. The supply will continue to flow and add to our already good inventories. There’s even a little surplus out there right now. Americans don’t like paying over .50 a gallon, and we will cut back our driving and subsequent spending on gas. So with my math, I’m coming up with 8 a barrel; for fuel and for fear. I think that the cost per barrel will dip below , and then go back up to 0 by the end of the year. However, after that, we might not see it come back off of that number.
So be prepared to reach deeper in your pocket to pay at the pump. No one likes the sound of a gallon for gas, especially my wife, but just may be the new regular number in 2012.
