An engine is called the heart of the car. A man can’t survive without a heart. So cars can’t run without an engine. If you have a manual transmission-based car, you need to rev up the engine. But if you have an automatic transmission-based car, you need a non-revving engine. There are also some separate things, for instance, the rev-up engine has Variable Valve Timing (VVT) on both exhaust and intake. In the meantime, the non-rev-up engine also has Variable Valve Timing but only in the intake cam. This article is about the differences between rev-up VS non-rev-up engines.
Different engines provide different power and come with some unique features. However, the engine of the car or any vehicle plays a crucial role in improving handling, braking, and performance. Plus, they control most of the work inside of the car. The rev-up engine has bigger cam covers than its counterpart. With a higher hp rating and less torque, the revved-up engine can increase the speed rate, animate, and stimulate the car. There is a difference between them in the internal books as well.
Rev-up vs. Non-rev-up Engine With a Table
|Basis of comparison||Rev-up||Non-rev-up|
|Basic concepts||The rev-up engine has different ECUs, separate ABS computers, wiring harnesses, internals, and intake plenums.||The non-rev-up engine has Variable Valve Timing with only an intake cam.|
|Engine types||It is a manual transmission engine that transmits the fuel manually.||It is an automatic transmission engine that transmits the fuel automatically after switching.|
|Peak power||It has quite better hp considering its counterpart. The peak power is 306 hp which is huge.||It has quite a better hp considering its counterpart. The peak power is 306 hp which is huge.|
|Torque configuration||The torque is lower than the non-rev-up engine which is 268 lb-ft.||The torque configuration is higher than the rev-up which is 270 lb-ft.|
|Amount of RPM||With 7500 RPM, it provides lots of power.||It has a lower hp than the rev-up motor but has a standard power of 6,600 hp.|
|Key features||With higher torque and a standard 6,600 RPM, it provides enough power.||The rev-up used an isolated oil pump, chain, and wearable timing cover internal component.|
|Valve timing availability||It helps to circulate and lubricate the oil properly which allows the car to run restlessly.||It also has VVT but only in the intake cam.|
|Best for||It has Variable Valve Timing on both the exhaust and intake camshaft.||A non-rev-up engine gives you freedom and flexibility while inserting fuel and repairing other parts.|
|Price range||Revving up the engine can cause the fluid to reach maximum pressure which helps to circulate oil, shift gears, and engage the clutch peaks.||It is an affordable and budget-friendly unit.|
Major Differences Between Rev-up and Non-rev-up Engine
Rev-up and non-rev-up engines have some great advantages. Rev-up engines produce higher horsepower while their counterparts have better torque. In most cases, they provide the same performance but they have some major differences. However, if you look at their price, you can see the difference between them. In terms of liberty and flexibility, adjustments, power and torque, variable camshaft, interior design, and many other areas they are separate.
If you have a manual transmission, you have the rev-up engine. Likewise, if you have the automatic transmission, you have the non-rev-up unit. What does it matter? Well, the transmission engine can change the gear. If you have a rev-up engine, it changes the gear manually whereas non-rev-up engines can change it automatically.
In general, the major difference between them is the exhaust cam. The rev-up engine has exhaust cam control along with an intake cam. On the other hand, the counterpart only has an intake cam. But both have variable valve timing systems.
Both have elegant interior parts and designs. But when looking at the interior components carefully, you see the subtle difference. However, in this case, the revving-up engine is ahead of the non-rev-up. Rev-ups have better quality interiors while the non-rev-ups have standard interiors.
Engine peak power and torque
The rev-up engine has more power with less torque. The peak horsepower of the rev-up motor is almost 306 hp with 7,500 RPM. Also, it has a lower torque of 268 lb-ft.
In contrast, the non-rev-up engine has a redline of almost 6,600 RPM, and peak power is 280 HP. Plus, it has higher torque than its counterpart and it is 270 lb-ft.
Better parts indeed give you a better performance indeed. So to buy better things, you have to pay a little bit extra. Anyway, the price range is not out of the limit. The rev-up cost is slightly higher than the non-rev-up unit.
Similarities Between Rev-ups and Non-rev-ups Unit
Besides the differences between them, they have some major similarities too. Before choosing, you need to know the similarities between them. However, they have similarities but are not so significant. Still, in this article, you’re going to read them.
Both engines are assembled by the Nissan Automotive Company Limited. They are also produced in the same country except for a few.
Both have the same size and shape cylinder head with variable valve timing. Also, they have almost the same materials in the cylinder heads.
With the best utilization, both provide perfect handling, braking fuel economy, and gears. Since they are made by a trustworthy brand, they are reliable and long-lasting units.
Strengths And Weaknesses of The Rev-up Engine
- Have both intake and exhaust camshafts.
- Provides better handling and pressure.
- It can produce lots of HP even in adverse situations.
- High-rating and top-quality unit.
- Better quality interior.
- Generally have oil consumption issues.
- Less torque.
Strengths and Weaknesses of The Non-rev-up Unit
- More torque is available.
- Better oil consumption.
- Reliable and budget-friendly.
- Circulates the fuel efficiently.
- Only has an intake cam.
- Produce less horsepower.
Rev-up Engine Is the First Choice for the Majority
Rev-up engines are the eminent units that contribute a lot to enhancing the handling and braking capability. Actually, it has a lot more power. The only main limitation is the torque issue. It has lower torque than the average. It uses Variable Valve Timing in both the intake and exhaust cam. That makes it stand out in the competition. It helps to speed up the car incredibly and circulate the fluid endlessly. Finally, it is a cool, calm, and calculative engine that produces better HP till the end.
Non-rev-up Is Budget-friendly Engine
The non-rev-up engine has higher torque with standard hp and RPM. It has a better oil consumption processing system to deliver better performance. It is made of an equal mixture of all things. If you want to get a sensational engine at a reasonable budget. There is no alternative to this. It also provides better gear changes, impeccable design, and stimulates power. Better fluid consumption makes it stand out from the competition.
You’re coming in the last paragraph of differences between rev-up VS non-rev-up engines. After discussing lots of differences and similarities between them, you may understand which is the best fit for you. Both engines have different incredible features that blow your mind surely. However, the main difference is their exhaust cam. The rev-ups have higher hp while the non-rev-ups have higher torque. Hopefully, all of you understand and can make the difference between them. Finally, I wish all of you to purchase a better engine to enjoy driving safely.
