horsepower?

[member]

if a car has more/less/around 10hp than the other car, does it make a big difference?
car A - 144
car B - 135

um. difference in what?

You talking about racing?

A lot of factors come into play such as driver skill, traction, etc.

Generally however, it should not be too much of a difference.

okay, thanks.

you're not gonna race are ya?

hp is not what you always base performance on. look at a dyno sheet to determine the peak hp and where it lies in the power curve and at what rpm, also the same with torque. a car with more hp can be slower than a car with less, theoretically. i can race a celica gts rated at 180hp and win (me at 175) because i have more torque where it counts. this is in a quarter mile of course.

I can pace with a GT auto celica rated at 140 hp with my 106 hp auto. W00t. .. he only starts to pull on me at around 40.

did you read my thread about the saturn?

[TeriyakiBroccoli]

erm.. dont recall so.

It has a lot to do with hp/weight ratio. If his car weighs 2k lbs with almost the same hp, say goodbye.

A peak horspower number does not tell you anything about how much power the engine has across the entire RPM band. A car with a horspower curve that is really 'peaky' is not going to beat one with a lower peak horsepower number but that has a higher average amount of power (torque, actually) across the entire RPM band. That is, unless you are only driving the car in that 'peaky' RPM range.

Another important point is that a car with a higher rev limit can stay in a given gear longer than one with a lower rev limit. What this means is that you can stay in a lower gear longer and take advantage of the torque multiplication of a lower gear. So two cars with identical horspower numbers but different rev limits would favor the one with the higher rev limit.

You need to look at the entire picture to compare the performance of two engines/cars. There are of course other factors such as power to weight ratio and drag coefficient, etc.

^^^ thanks man. good info.

[scottrtucker]

Any time

[Shot 2 Hel]

dude ive never seen you on here before, then you bust out with all this info


Welcome to HS, any pics o the Si

[scottrtucker]

No pics of the Si yet, it's still stock. I've gotta sell one of my other cars so I can buy wheels and tires and suspension and during the summer I am going to start fabrication of a cold air intake and figure out what else I can mod.

you can go to www.car-stats.com and look at some 0-60 and quarter mile times. they have a lot of cars on there so maybe it could give you an idea

cool, thanks.
