What is RWHP?

Created on April 3, 2016 at 5:45 am by admin



RWHP is short for a real term referred to as Rear Wheel Horsepower and among true car enthusiasts it can make or break the real world perception of the vehicle and its capabilities. Sometimes referred also as Real World Horsepower as all other calculations and numbers do not come close to the Seat of the pants feeling of true horsepower.

Rear Wheel Horsepower: the Basics of a “Performance Term”
People who make it a point to turn mere automobiles into undisputed “kings of speed” often stumble upon an important question while conversing with their like-minded peers: why is it vital to think about rear wheel horsepower? Well, the most experienced enthusiasts would surely agree that there are countless reasons why anyone who wishes to improve their car’s performance should learn about the various facets of such a measurement of power. As a matter of fact, there is no reason not to engage in such a quest for knowledge. After all, it would only be necessary to continue reading this article.
Thinking about the Basics
Before answering the “why” it would first be crucial to discuss the “what”. RWHP, as mentioned beforehand, is a measurement of power. This essentially means that an automobile with an impressive “horsepower value” would most likely have remarkable top speed and acceleration. At this point, it is already clear why speed-craving car aficionados continuously seek ways to “boost” their machine’s horsepower as much as possible: doing so makes their “ride” much more satisfying on the road. Now that the aforementioned value’s sheer significance in car tuning has been explained, it would be a must to focus on the matter of upgrades.
On Making a True Monster
One of the simplest ways to immediately, yet significantly, enhance a car’s rear wheel horsepower would be to add a nitrous system. Of course, many would begin to wonder just how much of an improvement would be gained from such an add-on. To put it simply, nitrous shots are sold based on the rough “horsepower value” that they provide, which means that getting a “125” would translate to an increase that amounts to almost 125HP. Aside from installing a nitrous system, making use of a turbocharger would also be an option. In fact, such an “upgrade” has the potential to double a machine’s horsepower.
The Concept of Evaluation
Automobile enthusiasts make it a point to use a dynamometer every now and then to “appreciate” their accomplishments, checking the difference between the stock RWHP and the “new and improved” rating. Many would begin to think of a certain question at this point: is there a way to evaluate the stock performance without having to remove every added component before running tests? Indeed, there is. The stock flywheel “horsepower value” only has to be multiplied by the right number, 0.20 for automatic and 0.16 for manual, to determine the core performance loss. Subtracting the “loss” from the “stock” reveals the base “rear wheel” power.
Expert’s Points to Ponder
So far, the following have been made clear:
• The rear wheel power directly influences both acceleration and top speed
• Improving such a value could be as easy as availing of a nitrous system
• Making use of a turbocharger is a superb way to boost power as well
• “Basic mathematics” is enough to pinpoint a car’s stock power
Making a monster out of a mere automobile is not without limits. Even though it would be possible to immediately double a car’s performance, there is always a risk of damage. In this sense, it would be best to maintain a balance between performance and stability, so that tweaking would remain a most rewarding endeavor instead of being the very definition of a costly mistake. All in all, enthusiasts should still exhibit caution no matter how intriguing their rear wheel horsepower boost attempts might be
