What's you power/weight ratio?

Power/weight ratio is using Ps(Hp)/kg?
Mine... 7gen, 4door, 2.0L, K20A3, EF1 about 1230/155=7.9 (all stock)
How's yours? What ratio is good?

Hrm never figured mine out:

2450lbs/170hp (crank) = 14.4hp/lbs.

That is the wrong equation. There is one out there, but I forget it. I mean think about it by throwing some extreme numbers in there. A 10,000lb car with 50hp will have 200hp per lb? Right.. Now working it backwards, SiRacer, your 14.4hp/lb is saying 14.4x2450 will equal 170.. do the math :)

more or less like 0.005 hp/lb

u divided wrong

weight / hp
mine is about 20 pounds per horse

i think my 98 EX coupe is more than 22

you said you had the K20 engine
do you like it
i am looking around for a possible swap in a year or two

Ricochet your wrong man.

2550 lbs and 162 crank horsepower equals 15.7 lb/hp

Hrm never figured mine out:

2450lbs/170hp (crank) = 14.4hp/lbs.

sorry guys, kg/hp is correct. Checked with spec, RSX has 7.5 ration.

CivicSiRacer.... 2450(1111.32kg)/170=6.53.....

K20A3 in my car installed originally from factory on civic body 4door. i'm here in the philippine. this engine used same on US Si and RSX base...

pretty good... none modi, powerful than my altis toyota 1.6L

couldnt tell you cuz I got no clue how much power a 11:1 B20 with LS cams, intake and exhaust pumps out. but the weights gotta be about 2250 with the engine and the wood in the back.
If i had to guess Id say its about 13.5lbs/HP

my old ride though was around 2.5lbs/HP.

my old ride though was around 2.5lbs/HP.

2.5lbs/hp? 1250lbs/500hp equivlent... or 450lbs/300hp?
sure?

Your equation is pounds per horsepower.. I'm looking for horsepower per pound, which would be a small decimal.

2400/315 whp (360ish crank) = 7.6lb/hp .. rough estimate holding 19psi with the new BC but mine kept dropping to 16-17psi on the dyno with a home made BC. Was going to use the GM boost solenoid with the EMS but it wasn't working and I took my AVC-R out before the dyno trip :( This is on a built D series motor.

Assuming 15% drivetrain losses about 4.86 pounds/horsepower, or 2.20 kg/horsepower.

Your equation is pounds per horsepower.. I'm looking for horsepower per pound, which would be a small decimal.Yeah I believe you're right, the equation should be kg/hp and not hp/kg.
For me hp/kg would be 13.27 and kg/hp would be .075 and I drive a 2044lb (929.1kg) CX with 70hp; so the later seems more likely to me.

2.5lbs/hp? 1250lbs/500hp equivlent... or 450lbs/300hp?
sure?

why dont you believe me, when did I ever say my old ride weighed 1250?

it only weighed about 380-400 pounds I think and had around 152 HP. it was an 01 R1, dont doubt it til you got all the facts.

it only weighed about 380-400 pounds I think and had around 152 HP. it was an 01 R1, .

cool..

Power to weight is overrated. 2 cars with the same power-to-weight could have a 1/4 mile difference of over 2 seconds.

yeah, gear ratios, tires, suspensions, where the peak power is, how much you have everywhere else......

1417kg-326hp=0.23hp thats more then enough for me
