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.
At a predetermined engine speed based upon the ECU, a 12V signal is sent to the engine’s VTEC solenoid, which activates the process.
Are Honda VTEC engines good?
Does VTEC really do anything? Yes and no; it depends on how you drive. Honda cars equipped with VTEC technology tend to be more efficient across a wider rpm range than many comparable vehicles, and they’re a lot of fun to drive in the right conditions, but most motorists won’t notice their VTEC kicking in.
What RPM does the 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.
How does a Honda VTEC system work? – Related Questions
Does VTEC save gas?
VTEC allows your car to control the intake stroke from high to low. This reduces fuel consumption and increases the performance of the vehicle even during difficult conditions. It will also allow you to reach higher speeds when you would not be able to do so under normal circumstances.
What’s the difference between i-VTEC and VTEC?
So, What’s the Difference Between VTEC and i-VTEC? i-VTEC adds additional valve timing control by allowing for adjustments to the angle of the camshaft. To maximize performance at both low and high RPMs you need the valves to open and close differently for each RPM range.
What is the fastest Honda Motor?
Civic Type R Crate Motor
As the most powerful Honda automobile production engine made in America, the Civic Type R’s 2.0-liter DOHC direct-injected i-VTEC Turbo® powerplant produces 306 horsepower at 6,500 rpm and a peak 295 lb-ft of torque from 2,500 to 4,500 rpm.
Do Honda Accords have VTEC?
Turbocharged 2.0-liter VTEC® Engine (2.0T models)
Drivers who demand higher acceleration performance will enjoy the Accord’s larger turbocharged powerplant. The Feature: This engine packs a variety of ingenious features to create a steady flow of power while tightly managing emissions.
What is a VTEC engine on a Honda Civic?
When did Honda VTEC come out?
The Confidence Needed to Innovate. Honda’s new Integra, equipped with the DOHC/VTEC engine, was introduced to the market in April 1989. The VTEC technology drew considerable praise as the world’s first valve mechanism capable of simultaneously changing the valve timing and lift on the intake and exhaust sides.
The Feature: Ridgeline is powered by a direct-injection V-6—a 3.5-liter, aluminum-alloy, single-overhead camshaft, 24-valve i-VTEC engine featuring Honda’s advanced Variable Cylinder Management™ (VCM®) system. Horsepower is rated at 280 @ 6000 rpm (SAE net), and torque is an impressive 262 lb-ft @ 4700 rpm (SAE net).
What is the best VTEC engine?
Which VTEC engine is best? One of the highest-rated Honda VTEC engines is the B18C6. This is a 1.8L 4 cylinder engine that could be found in the 1999 through 2001 Honda Integra and Acura Integra Type R from around the world. It produced 195 horsepower and 130 pound-feet of torque which was great for a car that light.
Does VTEC increase horsepower?
VTEC History
Traditionally, high-revving four-valve-per-cylinder engines sacrificed low-end torque to produce high-revving horsepower. The intricate relationship between the timing, lift, and duration of intake and exhaust valves set to produce high-revving horsepower generally hurts low-end torque.
Is VTEC faster than Turbo?
Turbo produces more torque and horsepower obviously while VTEC is more about pushing the maximum horsepower out of the engine since torque on VTEC cars can only be felt on VTEC range meaning anywhere after 5,500RPMs but yet the torque is still nothing compared with a turbo’s torque output.
What is the fastest VTEC engine?
High-rpm flogging is not required but makes for storming good fun as the 2.0L turbo 4-cyl. pounds out 306 hp before reaching the 7,000-rpm redline. With a specific output of 153 hp/L, this VTEC engine is the most powerful street-legal Honda ever to reach America.
Determine the optimum VTEC point by performing a dyno run on the low speed cam and then the high speed cam.
Set the VTEC rpm window lower rpm to the VTEC point value.
Set the VTEC rpm window higher rpm to 6000 – 6500 rpm.
Set the VTEC window pressure to 80 kPa up to the lower rpm value.
Can you improve VTEC?
VTEC engages and disengages based on the engine’s RPM’s. You can use software modifications to change the point where the VTEC system engages. This makes the more aggressive cam profile active lower in the operating range which can help make more power.
Can you remap a VTEC engine?
WE CAN TUNE I-VTEC, I-DTEC AND EVERYTHING IN-BETWEEN
Hyperchips has extensive experience chip tuning Honda cars. We can remap practically any model, whether naturally aspirated or turbocharged. The most common Honda models we tune have i-DTEC engines.
