Which is better VTEC or iVTEC?

Intelligent Variable Timing (and lift) Electronically Controlled (iVTEC), is a system that combines VTEC and VTC into one unit. The VTEC part of the system allows valve overlap to be adjusted at any moment, resulting in much greater efficiency and slightly better performance. …

In respect to this, Is VTEC bad for engine?

Not hitting vtec ATLEAST once a day can cause both problems to the driver, and the car. Without hitting vtec daily- the driver can develop a “light” foot. The car also suffers because it enjoys crossing over the line at 6000 RPM and making that nice growling noise.

Furthermore, Is DOHC better than VTEC?

Just wondering what are the main differences between DOHC vtec and SOHC i-vtec. Essentially speaking the biggest difference is the number of camshafts the engines have. DOHC engines are designed to rev higher, have peakier power outputs and PERHAPS high horsepower application.

Additionally, Does VTEC make a car faster?

Honda developed its Variable Valve Timing & Lift Electronic Control (VTEC) technology to make its cars quicker, more efficient, and more enjoyable to drive overall.

Is VTEC like a turbo? Unlike VTEC, a turbocharger doesn’t suddenly “kick in” at an exact RPM – it provides varying amounts of boost over a wide RPM range. VTEC is a “digital” device. It is either on or off resulting in a sudden transition and change in engine performance and sound at the engagement point.

Can you feel VTEC kick?

Registered. Yes I can, its at 4500 rpm, under that the engine is basically silent, then it roars up to redline, you can see the spedometer needle actually goes faster from 50-60mph then it does from 40-50 because the higher rpms in second gear.

Is it okay to hit VTEC?

No you will not harm your car by hitting VTEC a few times a day and redlining it. I can totally attest for the durability of these motors. Just keep up with your oil changes and maintainence, and you’re golden. It’s a honda.

Are DOHC engines good?

A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. DOHC engines also allow the spark plug to be placed right in the middle of the combustion chamber which in turn promotes efficient combustion.

Is DOHC VTEC?

The original VTEC system was introduced in Honda’s DOHC (Dual OverHead Camshaft) engines in the 1989 Honda Integra XSi and was first available in the United States in the 1991 Acura NSX. … The i-VTEC® system combines the original VTEC with Honda’s VTC (Variable Timing Control).

Why does Honda still use SOHC?

The biggest reason to use them is because DOHC engines are more expensive to produce (which price would get pushed back onto the consumer), there are more moving parts in them (which means they will fail sooner), and they can still do VTEC in either version.

Does VTEC increase HP?

VTEC is a type of variable valve-timing system developed and used by Honda. … At higher engine speeds, the cam profile allows greater valve lift, which allows more air into the cylinder. This helps generate more horsepower.

How much HP does VTEC give?

Its four-cylinder B16A produced 160 horsepower from just 1.6 liters—100 horsepower per liter—an unheard-of power density for automotive engines.

At what RPM does VTEC kick in?

It depends on the engine. Most Hondas had vtec crossover in the low to mid 5000rpm range. You had 2 camshaft profiles, 1 optimized for low-mid rpm driveability and fuel economy and another for mid-high rpm power.

At what speed does VTEC kick in?

At 3000-5400 RPM, depending on load, one of the VTEC solenoids engages, which causes the second valve to lock onto the first valve’s camshaft lobe. Also called 16-valve mode, this method resembles a normal engine operating mode and improves the mid-range power curve.

Does turbo shorten engine life?

2. Turbos Reduce the Lifespan of an Engine. One of the most common turbo myths is that running boost will damage your engine over time. … However, a properly implemented turbo pushing enough PSI through a motor to produce respectable levels of power won’t strain a motor any more than idling in traffic will.

Why are Hondas so fast?

Yes, Honda Civics are fast cars due to their excellent power-to-weight ratio, impressive drivetrain gearing, and shift points. What’s more, the Honda Civic can be made to go even faster than its stock form by spending very little money on customization and upgrades.

Does VTEC add HP?

Does VTEC add horsepower?

Why is VTEC so good?

The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance. And the transition occurs seamlessly, allowing for smooth performance across the entire powerband. The switching operation between the two cam lobes is controlled by the engine computer.

Does VTEC burn oil?

The answer is yes, you will. Its a Honda, they generally consume oil in vtec.

How do I know if my VTEC is working?

SO MAKE SURE YOUR CAR IS WARMED UP AND YOU HAVE A SUFFICENT OIL LEVEL. When the wires touch you should definately feel a differance, well, that is if your vtec is working.

What is more reliable SOHC or DOHC?

Compared to SOHC designs, DOHC engines have a more complex chain or belt drive system. This decreases overall reliability and adds to maintenance expense. As with SOHC designs, DOHC engine height is increased and overall weight also tends to be higher.

What cars have DOHC engine?

Most DOHC engines have four valves per cylinder, however DOHC engines with two valves per cylinder include the Alfa Romeo Twin Cam engine, the Jaguar XK6 engine, the early Ford I4 DOHC engine and the Lotus Ford Twin Cam engine. The camshaft usually operates the valves directly via a bucket tappet.

What does DOHC stand for?

Dual overhead cam engines are found in most modern vehicles today. They allow better airflow with less obstruction and are generally much more efficient engines than OHV or SOHC engines. Two camshafts operate 4 valves per cylinder, one separate camshaft for intake and exhaust valves.
