How can you increase horsepower? There are several fundamental principles if you are going to increase the acceleration of your car, aside from obviously shedding some weight. I'll explain some different methods of how to increase horsepower.

that's somewhat wrong. O2 makes HP, spark ignites fuel, fuel + compression burns O2. more fuel doesn't make HP.

@@FloydODB you need the right mixture, if you have more of both you will make more horsepower.

You have to have good enough air flow (volumetric efficiency) at higher RPMs, which typically requires modification of the valvetrain/cams. Also the valve springs need to be strong enough, and be able to last through many rapid compressions. The materials also need to be able to withstand the added friction.

Every time I see the EE videos I'm impressed by, 1) The knowledge of this young engineer put into down-to-earth terms and, 2) How much he looks like George Harrison (my favorite Beatle). Thanks for sharing. Keep up the good work. God bless.

I like the fact that he doesn't mention about Freeing up Exhaust pipe, some people do that and get so little to nothing, making so loud noise and car still moves so slow. The young men above is on the right track. I could hire him to work on flying vehicles in the future, as soon as I stopped the crooks.

The valve timing is connected directly with the crankshaft (geared to the camshaft) thus the timing shortens as you reach higher RPM. You would likely however need cams which open the valves a bit more to allow for greater airflow.

It doesn't let out less exhaust, it's turns the heat of the exhaust into useful energy, thus increasing the efficiency of the engine. The answer is yes, but many turbos are there for increased power, not necessarily for the most fuel efficient cars.

Spoilers increase downforce, thus increasing the maximum lateral g's that a car can hold (check out my video "traction circle" for more details) and allowing the car to go around corners at higher speeds.

@EngineeringExplained 11 жыл бұрын

It's not the "downforce" that the engine has to compensate for in order to accelerate, it's the drag. A 1000 kg car with 1000 kg of downforce still only has to accelerate 1000 kg of mass, not 2000 kg, however it has to compensate for the additional drag which will be significant.

It's not something you typically modify, but would require new cylinder heads/valvetrain for modified air flow at high RPM. And of course the strength to cope with higher RPM.

B/c of time constraints, bombarding w/ info can be counterproductive. leaving you 2 sort out the important. teachers forget important lessons. "Why" something works, and WHY it needs to work. Any1 can learn how something works by working on a part; taking it apart and rebuilding it. u become a better mechanic if u know the reasons why the parts work in that particular manner, n reasons why u r taking it apart.

No, I mean an overall reduction in the heat created at any moving contact points. For example, with the new CR-V Honda reduced friction by about 5-10% along the drivetrain, which was good for a real world increase in power.
