Small car body with large engine VS Big car body with small engine

[n_spinner06]

Ang dami ng nag comment pero wala pa*ni isang gusto sumagot.. Puro therory lang ba tayo guys.. Hindi ako car expert kaya nag tatanong ako.. Basic lang alam ko pero yung iba kung makapag comment e parang expert talaga. Aral na aral ang sasakyan. Power to weight ratio lang po ng tricycle ang usupan natin..175cc engine, 7 person plus sidecar.. Ano po ang power to weight ratio niya? Then panu e compute..

let's not get too excited. theory lang naman talaga yung labanan kasi yung kotse na iniisip mo wala pa naman actual unit at theoretical lang din naman. for discussion's sake, power to weight ratio is a good metric pero it is not the be-all and end-all kung baga so that's beside the point. kung yung pinaglalaban is kung posible o hindi yung kotse na iniisip mo, posible. yun nga lang maraming trade-offs (safety, makupad, reliability, baduy, etc.) some of these points are valid, some are subjective and you can get a general feel of how car enthusiasts (albeit not the general public) would feel about your planned car. now for a lot of people here, the trade-offs are not acceptable pero kung for you ok lang kahit redline ka na at 60kph lang pero maporma kotse mo, then why not? no need to argue. 60kph naman ang minimum sa tollways natin so i don't see how that would be a safety issue kung pasok naman. maingay nga lang ang kotse mo at yung relative konsumo would be more because of the added load (weight, aerodynamic, etc) compared sa walang load.

while i consider your question as silly, may be this can enlighten you. weight-power ratio. ang weight ng tricycle, say 200 kilos plus 7 persons*50/person =550 kilos lahat, as against sa power ng 175cc tricycle. para makita mo ang point ko, compare the maximum output ng 175cc bike without load, then its maximum output with the 550kls load. maybe you got my point already. if the max speed at a certain rpm is, say, 130kph without load, can you expect the same speed with 550 kls load? kaya yong tricyle mong sinasabi, can never hit even 60kph with load, kasi underpower na siya, dahil sa weight ng load. by the way, a review in physics can help you on this. anyway, its your money, walang basagan ng trip dito.[/QUOTE]

Thanks. Hehe.. Nice idea of computation.. Sir, how about up hill? Ilang degree kaya niyang akyatin?

errr... before asking the second question... how do you know if his computation is correct or not?

Either you're a troll, or just stupid. Or a stupid troll. In any case, you can never have negative power-to-weight ratios because power (HP) and weight (kg) are always positive. Positive divided by positive is always positive.

Anyway, to humour you since you like numbers:
Kawasaki Barako - 13.5 HP
Weight with 7 passengers - 530 kg
Power to weight ratio: 25 HP/ton

Sure, it moves, but with a top speed of 30 kph and lots and lots of revs and smoke.

GT-R with Vios engine: 47 HP/ton
Much higher than the loaded Barako, if that's your point. But it'll still be a very slow car. An L300 has the same P/W ratio but that's a diesel which is why it can climb easily despite not having power. Of course, its top speed up a steep hill is pathetic.

Ultimately thogh, what you want is possible. So why not go ahead and do it? Make a statement to all your haters!

Oh wait, wala ka naman palang pera. Puro drawing nga lang pala 'to.

Nice data.. Haha. Thanks.. So may dream sports car is not imposible. Hindi nga lang matulin. How about uphills sir? Ilang degree kayang akyatin ng gtr body with vios engine? Sabi nga sir lahat nag sisimula sa pangarap. 2nd hand palang mga car ko at 1st time namin bibili ng swift 1.2 na brand new.. Hehe..

Sir makupad lang siguro ang issue.. Hehe.. Safety? Baduy? Reliable? Parang hindi naman..

no... you have to buy my computations from me.

and these is just newtonian physics.. we used to do these in our spare time, for amusement.

philsat, may sasakyan ka na ba?

philsat, may sasakyan ka na ba?

Isang vios na luma at tamaraw fx na service minsan ng mga tao ko.. Haha. This year try naman namin ang brand new na swift 1.2
