Fuel To Fire

Growing up with performance cars is like pushing every corner of my abilities to the fullest. Started to appreciate Honda DC2 at the early age of 12. Followed by Evo IV at the age of 14.  Some might said my life revolved around VTEC and Turbo.  But, kicking the horsepower of these cars is my daily joy.

Do you have something in your early age to push you to the fullest?

My Pride, My Glory, My EG!

I came across this unique shop located in KLANG. I know it is so darn far. Trust me, it worst a try. Looking at those display, it makes me wanting to get my hands dirty for the right reason. 

Unfortunately, the society sees me as a girl. A girl who know nothing.

Let me tell you what I know about a thing called TURBO.

A turbo is a turbine-driven forced induction device that increases an engine's efficiency and power by forcing extra air into the combustion chamber. This improvement over a naturally aspirated engine's output results because the turbine can force more air, and proportionately more fuel, into the combustion chamber than atmospheric pressure alone.

Turbo Lag

Turbo lag is the time required to change power output in response to a throttle change, noticed as a hesitation or slowed throttle response when accelerating as compared to a naturally aspirated engine. This is due to the time needed for the exhaust system and turbocharger to generate the required boost. Inertia, friction, and compressor load are the primary contributors to turbocharger lag. Superchargers do not suffer this problem, because the turbine is eliminated due to the compressor being directly powered by the engine.

How Turbo Work

When people talk about race cars or high-performance sports cars, the topic of turbo usually comes up. Turbo also appear on large diesel engines. A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbos so popular!

How a turbo increases the power output of an engine while surviving extreme operating conditions. And also, how wastegates, ceramic turbine blades and ball bearings help turbochargers do their job even better. Turbochargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging. This can significantly improve the power-to-weight ratio for the engine.

In order to achieve this boost, the turbo uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) -- that's about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high.

Street Turbo

A good street engine should have a smooth idle, have lots of low end torque, a wide powerband, long life and good fuel economy. To get these characteristics, most street engines have relatively moderate camshaft timing, small turbos, small diameter intake ports with long runners and usually cast pistons. They are designed to run on gasoline with an octane rating of  RON 95 in most cases and usually produce less than 100 hp/liter in naturally aspirated form and 120 hp/liter in turbocharged form.

Do You know after L2 - Daihatsu have this called K3VET?

Race Turbo

Ideally, a good race engine should have all of the same characteristics that the street engine has above but since high power output is one of the primary concerns, many compromises in those other desirable traits must be made to achieve this power level. To achieve higher power, ports are opened up for increased flow at high rpm and camshaft timing and lifts are increased, both of which kill off low rpm torque, power, fuel economy and that smooth idle.

The rpm capabilities are upped to permit higher airflow rates. This is usually done by changing to stronger parts such as connecting rods, pistons, crankshafts and valve springs. If the engine is turbocharged, a larger turbo and intercooler along with forged pistons and stronger rods are fitted to handle the loads. Raising the redline will not make any more power in most cases unless the engine components are modified to efficiently pass that increased airflow.

RB 26 THE BOMB

On naturally aspirated engines, the compression ratio is often raised substantially to boost torque and power. This is possible when using high octane race fuel. On turbo engines, the compression ratio may either be raised or lowered depending upon fuel octane allowed, maximum boost pressure and possible fuel limits for the race.

As you can see, the two engines vary considerably in requirements and execution. The problem comes in when someone wishes to increase the power output of a street driven engine beyond reasonable limits while expecting no major degradation in "streetable" qualities.

On street driven at most engines, there are minimal gains to be had on most small engines without sacrificing a lot of driveability. If you need more power, you need a larger engine usually. Expecting your 18 second car to do 13 seconds while retaining good idle and fuel economy when modified is unrealistic most of the time.

Turbocharged race engines can produce staggering hp numbers given strong enough parts however engine life goes down as power is increased. A narrow powerband may be acceptable on a race engine because close ratio gearboxes are usually fitted to minimize rpm drop between shifts.

There seems to be two types of people preparing turbo race engines for import drag racing. One school uses small, stock based turbos for quick spool up. These engines run super high boost but don't make any power. School two fits turbos which are way too large. These have poor turbo response and a super narrow powerband.They produce very high hp across only 1000 rpm on the top end and as a result are not very quick. Bigger turbos don't necessarily mean quicker times. Turbos must be properly matched on the compressor as well as the turbine end.

Some people really know what they are doing and some don't. 450 hp out of a 16 valve 1900cc drag motor at 25 psi is just not impressive.

If you need to tune your car to either Race Turbo or Street Turbo mode, do head down to KLG Auto. Trust me, they can do a good job on what you wanted for your ride to be.

Saw their display on one of the event. While friends around me had tried their services, they smile all the way to the podium.

They are located at :
