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 to improve 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 a lower hp than the rev-up motor but has standard power of 6,600 hp.|
|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.||With higher torque and standard 6,600 RPM, it provides enough power.|
|Key features||The rev-up used an isolated oil pump, chain, and the wearable timing cover internal component.||It helps to circulate and lubricate the oil properly that allows the car to run restlessly.|
|Valve timing availability||It has Variable Valve Timing on both exhaust and intake camshaft.||It also has VVT but only in the intake cam.|
|Best for||Revving up the engine can cause the fluid to reach maximum pressure that helps to circulate oil, shift gears, and engage the clutch peaks.||A non-rev-up engine gives you freedom and flexibility while inserting fuel and repairing other parts.|
|Price range||Considering benefits and advancement, it costs slightly higher than non-rev-up bibcock.||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 produces higher horsepower while its counterpart has better torque. In most cases, they provide the same performance but yet 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 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 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 available.
- Better oil consumption.
- Reliable and budget-friendly.
- Circulates the fuel efficiently.
- Only has an intake cam.
- Produce less horsepower.
Rev-up Engine Is First Choice for Majority
Rev-up engines are the eminent unit that contributes a lot to enhancing the handling and braking capability. Actually, it has a lot more power. The only main limitation is in the torque issue. It has lower torque than the average. It uses Variable Valve Timing in both 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 in the competition.
You’re coming in the last para of differences between rev-up VS non-rev-up engine. 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.
