power to weight

[h22a accord]

hey guys, pretty straight foward, divide the kilowatts your engine produces by the weight of your car. eg 2000 (kg) divide 200 (kw) = power to weight of 10kg per kw

Now i'll do my car 1300kg divide 149kw =8.72kg per kw


whats yours?

[ekslut]

My ED Civic:

Weight Standard 850kg; Stripped 50kg out of it on the weekend

Getting a 118kw engine put in at the moment (Think its 118kw anyways. Its a jap spec 90-93 Integra Engine)

Therefore 800kg divide 118kw = 6.78kg per kw

farkin awesome!!! whats the standard motor pump out?

[ekslut]

Think standard its about 75kw....not postitive though

hehe...so im going from 11.33kg/kw to 6.78kg/kw :D

My old mirage:

62.4kW ATW = about 80kW at the fly
935kg
11.7kg/kW

My Del Sol:

116kW
1175kg (i think?)
10.1kg/kW

[tinkerbell]

if we are talking about *flywheel* Kw to weight

950kg / 180kW = 5.2kg/kW (in race trim)

i think my car did sub 6 seconds 0-100km/h

(shame i sold the engine, the next one will be more powerful though...)

[fusion_VTi]

1000kg/100kw, about close to 10kg/kw i'd say

[dave_ed9]

once i get my swap done, i'll be

850kg/130kw (approx)

so about 6.5kg/kw :)

1200/200=6

[MKI4EVA]

7800kg/68kw@wheels.........11.47..........

whats the use of doing this if ur taking KW at the crank?

[h22a accord]

u have missed the point, this is the point. the standard rule for measuring power to weight is kw at flywheel.

[SIKCVC]

power/weight is a ratio...

the other way it can be writen (which is how VIC roads measures the P plate restriction) is actually Power/weight.
ie, an SiR has 118kwts/Tonne. from 125kwts/1.050tonne or 1050kgs... but that will give you kwts/kgs.

[Weq]

what about modified cars, which dont have powr readings at the crank + is it dry weight or what :P
so many varibles.

[tinkerbell]

my figure was arrived at by comparing the 100ish kW being put out by stock DC2R's and DC5R's on the same dyno i put out 121kW...

so, if the factory flywheel figure for both the DC2 & DC5 is quoted to be 147kW

then i am putting out 121/100 = 1.21 times more power

and since 1.21 * 147 = 177kW

i guess you could extrapolate that i am putting out 180ish Kw at the fly...

plus weight is factory quoted weight, and since i ahve quoted 'track weight' i know my track weight is abt 70kg lighter than factory...

hence my figure of 5.2kg/kW

(plus i rounded everything to my favour...)

ED6
950kg/150kW= 6.3kg/kW
Flywheel calculated same as tinkerbell's. [not 100% sure of car weight, flywheel + or - 5kW]

3.8:1 with old car

Bit over 2:1 with new one

[BLKCRX]

20 psi 322kw hmm 1100kg thats 3.4

more boost 400kw thats 2.75

hmmmm

ok guys, a bit off topic but the work "MOKE" caught my attention
it was my first car and still have it!!

if u are doing to a moke what ive been thinking of doing to a moke for years then you are one crazy assed dude.


My plan is a b16a moke. like 650kg with 160hp hehehehe.


either i buy the b16a subframe mounting kit from UK or fabricate one locally.


I have my moke sitting in my back yard.... the same week that i decided to start this project i blew the diff to smithereens in my accord and decided to do a h22a swap which drained my fundage for a while.
