What is the rev limit on the F20C?
The F20C engine, famously used in the Honda S2000, is a high-performance, naturally aspirated inline-4 engine that has gained legendary status among car enthusiasts. Known for its incredible engineering and high-revving nature, the F20C is a marvel of automotive technology. In this article, we’ll explore the rev limit of this iconic engine and what makes it so special.
The Official Rev Limit of the F20C
The F20C engine has an official rev limit of 9,000 RPM. This is one of the highest rev limits for a production car engine, especially for its time. The engine was designed to deliver peak performance at high RPMs, with its redline starting at 8,800 RPM. This high-revving capability is a result of Honda's meticulous engineering, including lightweight components and a robust valvetrain.
Why Does the F20C Have Such a High Rev Limit?
The F20C's high rev limit is achieved through a combination of advanced engineering techniques and high-quality materials. Here are some key reasons:
- Short Stroke Design: The F20C features a short stroke and a relatively large bore, allowing the engine to rev higher without excessive stress on the components.
- Lightweight Internals: The pistons, connecting rods, and other internal components are designed to be lightweight, reducing inertia and enabling higher RPMs.
- High-Strength Materials: The engine uses forged components and high-strength alloys to withstand the stresses of high-speed operation.
- Advanced Valvetrain: Honda's VTEC (Variable Valve Timing and Lift Electronic Control) system optimizes valve timing for both low and high RPMs, ensuring smooth operation and peak performance.
How Does the Rev Limit Impact Performance?
The high rev limit of the F20C allows it to produce significant power despite its relatively small displacement of 2.0 liters. The engine generates 240 horsepower at 8,300 RPM, giving it one of the highest specific outputs (horsepower per liter) of any naturally aspirated engine in a production car. This makes the F20C a favorite among enthusiasts who enjoy the thrill of high-revving engines.
Conclusion
The F20C's 9,000 RPM rev limit is a testament to Honda's engineering prowess and dedication to performance. Its ability to deliver power at such high RPMs has made it a benchmark for naturally aspirated engines and a beloved choice for car enthusiasts worldwide. Whether you're a fan of the Honda S2000 or just appreciate finely tuned engines, the F20C is a true masterpiece of automotive engineering.
Frequently Asked Questions
What is the max rev on the Honda S2000?
9,000rpm
Honda S2000 – 9,000rpm
Yep, we're into the 9k club already, with the fantastic Honda S2000 and its ridiculous 2.0-litre VTEC that revved sky high. Later iterations would lower the rev limit substantially, but still, the early S2000 honoured its S800 predecessor magnificently.
How can I remove my rev limiter?
How to remove the RPM limiter? This electronic command module which limits the RPM quantity in order to save your engine from being damaged cannot be physically removed. However, you have the possibility to change the ECU stock with a high performance ECU. This process will authorize you to go beyond the RPM limits.
What is the rev limit on the k20 Type R?
K20A (i-VTEC)
| Engine | Application | Rev limiter |
|---|---|---|
| K20A (High Performance) | 2001–2006 Honda Civic Type R (JDM) | 8400 RPM |
| 2001–2006 Honda Integra Type R (JDM) | 8600 RPM | |
| 2002–2008 Honda Accord Euro R (JDM) | 8400 RPM | |
| 2007–2011 Honda Civic Type R (JDM) | 8600 RPM |
What does a S2000 redline at?
The S2000's crown jewel, however, is a 2.0-liter naturally aspirated four-cylinder engine pumping out an incredible 240 horsepower at 8300 rpm and revving to an 8900-rpm redline.
What is the highest RPM limit?
The RPM limit varies by bike model, typically between 7,000-15,000 RPM. Exceeding the limit can damage the engine.
What is the highest revving F20C?
The F20C was designed with high engine speed capability in mind, for increased power output; the rev limit is 9,000 rpm, with VTEC engagement at 6,000 rpm.
What rpm is safe to rev to?
In class (AMT 300 Shop Basics), we were taught that the standard safe RPM that you can rev then engine up to (basically the all day every day number) is 75% of the redline. So if my engine revs up to 8,000 RPM but the redline starts at 6,500, my safe continuous rev limit wold be 4,875 RPM.
What is the rev limit on a stock sr20?
If you have a stock valvetrain 7200 is the limit. Well technically 7500. I wouldn't rev to either without RAS, valvesprings, retainers, and solid pivots. 8200 = a demolished head.
Which S2000 revs to 9000?
The F20C was more like a motorcycle engine than other automotive designs, both in layout and specific power output: The F20C whizzed through its rev range to a stratospheric 9000 rpm redline, producing 240 horsepower at 8300 rpm.
How high can a sr20 rev?
If you have solid lifters then 8k is possible. You can raise the limit on pro cams with hydraulic lifters also iirc. thats the standard for early redtop ecu's. nissan reduced it to 7250 soft / 7400 hard on later models (type x).
