Does A Lightweight Car Make More Horsepower

[red rpm]

hi

i was just wondering if a light weight car would make more horsepower or not?

just thinking if a light weight car would have more power but would it make more horsepower on a dyno

i have asked lots of people some say that it would because some dynos are specially for engines and it gives you engine horsepower and the normal dyno gives you horsepower at wheels

so what do you think

[PM-R33]

Lol you are kidding right?

Horsepower in a measurement of work done over time. It has absolutely nothing to do with how heavy a car is.

Mate I would have a go at re-writing that

But I know that when they strap a car down, how hard it is strapped will have an effect on the power reading but i think its fairly marginal and would eliminate most of the "weight issue' that your talking about anyway

Your not talking about power to weight ratio? I cant quite understand half of your post.....

Yeah I really think he must mean power to weight ratio or something. No one could seriously think that an engine makes more power just because you remove two fat chicks from the back seat.

yup

this what i wanted to say

power to weight ratio

sorry for the english maby not lot of u people counld understand my english cus its my second language

and i was just asking and learn more from people

[PM-R33]

Well yeah, obviously the lighter the car, the better the power to weight ratio it has, quite simple really...

Weight has nothing to do with power. You will have better acceleration because there is less weight to move - that's it.

There is a car club in the USA that got a standard Nissan sentra and started from standard weight and pulled a 16sec 1/4 mile pass. Then completely stripped the panels so it only had the engine, floor pan and running gear and pulled a 12sec pass.

Hahahaha I remember reading that/seeing the pictures.

I have an old Zoom magazine where they did a similar thing to a R33 GTR.

weight goes not change the power of the car the power is what the motor is putting out !!.

but a lighter car will allow you to make more use out of that power for example if you have a 300hp patrol and a 300hp minni the minni will be faster because theres less weight for the 300 horses to pull

[PM-R33]

I think it is safe to say this does not need to be discussed any furthur. I think 99% of people understand that a car that is lighter will be faster than a heavier car with the exact same horsepower output.

yes, is this very much correct. A Lightweight Car Make More Horsepower because The "torque loss" sensation is a similar phenomenon, except it's mainly a problem with driving habits.

Zzzzzzzzzzzzzzzzz......

if i fit 22s on a 33 will it also make more horsepower?

Don't know about that one...

But it has being proven that if you paint your brake calibers red it will increase your power by 25rwkw & putting those flower stickers on the back window (like those you find in those Hyundai Excels, Getzs driven by girls) will furthur increase your power by 5rwkw per sticker.

of course you can also increase horsepower by attaching horses to the car..

But to save weight you would be better off getting smaller horses

a cars weight has nothing to do with "torque loss".

a car making "1000nm" will make it whether the car weighs in @ 1tonne or 2tonne.

drivetrain differences *might* have an impact, but it'll be minor for the sake of this topic.

surprised you guys are even responding.

it's school holidays, yo.

And everyone knows there's 10rwkw in a TBI pod filter (the dyno graph on the back says so), and they're only like $15! So for $750 spent on TBI performance parts you can gain 500rwkw!

But only when you piggyback 50 TBI pods into your intake!

But they have to be joined with blue silicone hose from Supercheap, and a sticker saying so on the skirt...
