Why do same size engines have different horsepower?

Why do same size engines have different horsepower?

The main reason is that the engine is dependent on the intake and exhaust routing to make maximum horsepower. A more restrictive airbox and ducting on the intake side and more restrictive exhaust will reduce peak hp. Also, there could be different tuning parameters in the ECM .

Why do some cars run faster than others?

Horsepower is made by the engine which is obviously the main cause of speed. A bigger engine means more speed . Another thing that effects speed is the power to weight ratio. That means that the heavier the car, the bigger the engine needs to be.

Why are some engines more powerful than others?

Engines make power by moving air through them. A smaller engine can move more air than a larger one by having better flowing heads, turbochargers or revving much higher or any combination thereof. The more air you can move through an engine matched with proper fuel, the more power you’ll make.

Why are some engines faster?

As a larger engine is usually able to burn more fuel and produce more power, a car with a larger, more powerful engine is likely to be able to accelerate faster and tow heavier loads than a car with a smaller engine can manage. One key to this is turbocharging, which forces more air and fuel into each cylinder.

How does the GTR accelerate so fast?

The Nissan GT-R is fast thanks to what Nissan calls the Premium Midship platform, with a rear-placed transaxle and a lightweight but very powerful twin-turbo V6 engine in the front. This means that no matter how powerful the engine is, the rear wheels will spin on hard acceleration.

What makes a car go faster on the highway?

It’s the transmission that helps get a car to go faster. A mechanical engineer explained to me that the quest for improved fuel economy meant having a cvt transmission that can move a car faster at lower rpm to save fuel. It meant trying to make the normal highway speed a sweet spot for fuel economy.

Why are sports cars so much faster than normal cars?

The thing is only sports cars are made to go that fast. Normal cars are made for fuel economy and it just so happens they can go fast because of the transmission but will fall apart sooner going super fast. Ohh…and the traffic enforcement by not letting cars speed.

Are all F1 cars capable of running at the same speed?

To answer your question, no. All F1 cars are not capable of running at the same speed. Currently, we have 4 engine manufacturers in F1 – Mercedes, Ferrari, Renault, and Honda. If you’re an F1 team, you either make your own engine or buy engines from one of these 4 manufacturers.

What is the difference between a racing engine and a Champ Car?

A racing engine, on the other hand, has a short stroke. The piston in a racing engine has a large diameter for the engine size, and it goes up and down a relatively short distance on each cycle. This means that a race car engine can run much faster — up to 15,000 RPM in a Champ Car engine — but has relatively little torque.
