How much horsepower do you need?

**badkuk** · August 31st, 2003 06:00 PM

Hi All!

Meron bang formula to calculate how much hp you need? Indulge me for a moment

kc all the brochures/specs tell you about hp and torque, but how does it translate in the real world?

Given:

1. Number of passengers;
2. Average weight of passengers;
3. Steepness of road( 45 degrees, 60 degrees);
4. etc.

maeestimate mo ba kung gaano kalakas na auto ang bagay sa yo?

I'm pretty fine with 99.

Otep, i think were up to 110+ :D Washers remember? :D

OT:: Sabi ng C! 114hp daw 4D46TDIC!!! Yehey! Instant hp increase!

I guess your question needs to be more specific. What are you trying to achieve? Hp and torque will come into play when you talk about acceleration and engine responsiveness. If your only talking about climbing a hill even with 4 passengers, this can be achieved with very little horsepower and very low gearing.

A 12 hp motor if geared right can carry even more than that. It's just not going to be fast. Conversely, a 200 hp motor wont climb a steep hill from a standing start if it's gearing is way too tall. You have to tell us what your criteria is and then a suitable answer can be made.

hmmm...napansin ko lang kc na hirap ung ol' reliable 1.3L AE92 nung paakyat ng undergnd parking sa megamall...3 lang kami sa car(i guess arnd 480lbs in all), with the aircon at medium, naka segunda....parang hirap lang sobra eh. Nakaka akyat naman, pero di convincing

1st gear lang naman dapat ang gamit when climbing. makikita mo rin naman in most multilevel parking a sign that says "STAY ON 1ST GEAR"

my real answer: too much hp is just right!! :D

the more applicable answer: in most philippine driving, i would think the modern 1.6L engines are more than enough. for climbing and the general feeling of having power/acceleration, you should be looking at the engine's torque curve - torque peak, at what rpm does it achieve peak, etc.

some engines (like the honda vtec) make all their power at high revs...that is fine but to some people it feels 'hirap'. others (like the american cars) make more power down low....generally speaking, bigger displacement engines have more of the pulling power or 'arangkada' you seem to be looking for...
