power to weight ratios for all motor

[tenshi_R]

i was looking thru some common production car power to weight ratios and thought id put up a list of what you can expect with all motor.
checking out evan's tuning it seems like 180-225 is a comfort zone for modded integras all motor.
with that in mind m gonna try to explain in real world car number parrots the power to weight ratios for most common street cars and how we rank against them.

here are some quick integra numbers
------------------------
stock(using crank HP numbers)
rs 17.8lb/hp
rs with gsr swap 14.8lb/hp
rs with R swap 12.9lb/hp
gsr 15.6lb/hp
tpe-r 13.3lb/hp
------------------------
dont have info on type-s or any k series
------------------------
tuned cars(using WHP/ crank hp conversion) /.85 hp
i used a whp/.85 formula to get APPROXIMATE crank HP numbers
from evans tuning
Integra, LS/vtec, N/A, 192whp/148tq,(225hp) 11.7lb/hp
Integra ITR, NA, 242whp/165tq, Stock PR3 head,(282hp) 9.2lb/hp
Integra, ls/vtec, OEM components, 165whp/124tq (195hp) same as above stock type r
1998 Integra Type R, I/H/E, Neptune 182whp/134tq(214hp) 12.1lb/hp


now to give you an idea how we rank against some other common production cars

Model=HP / lbs per horsepower

Acura TSX=205 / 15.7
Acura TL=286 / 12.6

Audi TT=255 / 10.9

BMW 3 Series=300 / 10.9
BMW Z4=330 / 9.1

Bugati Veyron 16.4 =987/4.2

Cadillac CTS-V=400 / 9.2
Cadillac STS-V=469 / 8.2

Chevy Cobalt SS=205 / 13.5
Chevy Corvette Z06=505 / 6.3
Chevy Impala SS=303/ 11.7
Chevy Malibu SS=240 / 13.2
Chevy Monte Carlo SS=303 / 11.0
Chevy Trailblazer SS=395 / 12.0

Chrysler 300C SRT-8=425 / 8.7

Dodge Charger SRT-8=425 / 8.9
Dodge Viper SRT-10=510 / 6.7

Ford Mustang GT500=500 / 6.7
Ford Mustang GT=300 / 11.5

Honda S2000=237 / 11.9
Honda Civic Si=197 / 14.6

Hyundai Tiburon=172 / 17.3

Infinite G35=315 / 11.1

Jeep Grand Cherokee SRT-8=425 /11.2

Lexus IS350=306 / 11.3

Mazda RX-8=238 /12.7
MazdaSpeed3=260 / 10.3


Mercedes CLK=475 / 7.5

Mini Cooper S=175 / 14.5

Mitsubishi Evo XI=286 / 11.18
Mitsubishi Eclipse=260 / 14.1

Nissan Altima=365 / 11.5
Nissan 350Z=315 / 10.6


Saleen S7 Twin Turbo=750/ 3.9

Saturn Ion=205 / 13.4
Saturn Sky=260 / 11.2

Scion tC=161 / 18.0

Subaru STI=293 / 10.3
Subaru Legacy=250 / 12.2

VW Jetta=200 / 16.1
VW GTI=200 / 15.8

Volvo V50=218 / 14.8
Volvo S60=300 / 11.6
Volvo V70=300 / 10.98
Volvo S80=311 / 11.2



so what it means is.
if the number you have is less than number of the car you trying to race your car wins( depending on the driver )

for example
stock integra RS 17.8 would probably only beat scion tc (18.0)

with a gsr(15.6) you have few more choices lol you can try to take on a tsx or maybe a tiburon or a VW.

now to give you a better idea

a stock RS weight about 2530lb with gsr swap it has 14.8lb/hp whic is 170 hp for the motor
say you want to go up against subaru STI which has 10.3lb/hp
you would have to have less than 10.3 lb/hp and (2530lb/10.3lbhp) make more than 245 HP in order to keep up with it with wheel power adjusted again approximately 210HP at the wheel.
but thats not counting in the torque and many other things.

good job
good stuff

That's cool, the MS3 is awesome. I raced a new g37 the other day and could have pushed him down the street.

 

[mohawk42s]

i suggest a sticky... just saying

 

[tenshi_R]

also please correct me if im wrong in any of my calculations.

 

[dc2GS-R]

The Altima doesn't have 365hp.

Keep in mind this doesn't take many real world factors into account. Consider the IS350 is rated near the S2000, G35 and Impala SS but will readily hand them their ass in the 1/4 mile. This is only one factor.

But it does make it clear why a Civic Si won't smoke a Saleen S7.

 

[Aussie]

Very true, gear ratios, power curve, torque, traction, and many other factors come into play.

 

[Rich-PMS]

My pitbike has 18whp and weighs 126lbs. 7lbs/ per whp.

I vote a sticky too.

 

[dc2GS-R]

My pitbike has 18whp and weighs 126lbs. 7lbs/ per whp.

My GSX-R 750 has 172rwhp and weighs 370lbs soaking wet. 2.15lbs/whp :naughty:

 

[Aussie]

Do you have work done to it? Then new zx-14 only puts like 150hp to the wheels.

[tenshi_R]

umm. not really a bike place lol. post some more integra numbers for other years.
or some other tpical cars that try us every day please.
im putting together a list of of all other integra models.
dont really have weights and powers for hondas(civics s2000 crx etc)
