Just curious as to what people are geting for their horse/weight ratios out of their 2.2's. I have 1hp:9.4 lbs. For comparison, here are some 2005 sport cars. Lotus Elise, 1hp:10.3 lbs. Corvette Z06, 1hp:7.7lbs. Viper SRT-10, 1hp:6.8 lbs. Ferrari 360 Modena, 1hp:7.7 lbs. Porsche 911 GT3, 1hp:8.3 lbs.

 

Either you've got over 300hp, your car is 1300lbs or some combo in between.

Details?

 

1 hp / 9.4 kilogram maybe?

 

our cars are more like 1HP/17.93 lbs

 

2900lbs - 150hp = 19.33333 (i think)

 

SS S/C 2900lbs / 205hp = 14.146341

 

SS N/A 2900lbs / 171hp = 16.959064

 

just weighed the car today 2908 lbs 3148 with me in it. Haven't dynoed but im guessing 217 (stock).

Theoretically

Car.....................13.40
Car w/me............14.51

 

Stock 05 Cavalier = 2617lbs. Lighter hood, wheels, tires, no spare tire, restrictive extra engine crap for intake and exhaust, lighter springs.....added weight with N20 and extra piping for exhaust = 2535lbs. 272.4 horsepower. = 1:9.306 All of the sport car #'s were done with their base horsepower, not wheel, so I used that too.

 

Unless that restrictive extra crap is now a big turbo charger, BS.

 

Where do you weigh your car at? I have stripped a lot of my stuff and would like to see how much ive gotten out !!

 

lbs per hp is the usual designation.


2815/171= 16.4lbs per hp

Know whats a horrible one? Hummer H3---22lbs per hp!!

 

Nice power to weight ratio! What kind of times have you run?

 

Know whats a amazing one? Bugatti veyron ----- 4 something

 

The restrictive crap was only a 9.5 lbs reduction. Man, you're right...That IS hard to believe.

 

Only ran an 1/8 mile. I'd hit the limiter with the N20 in a 1/4. But 8.346 is my best ever in the 1/8th.

 

congrats on the mods travis, congrats on installing bolt ons and N2O. you have a right to be proud.
so how many more threads are you going to post boasting?

 

How much does the 2.2, 2.4, and the 2.0 weight stock?

 

This is what GM US says they weight

Coupe 2,991 lbs
Sedan 3,216 lbs

This is what GM CAN says they weight

Curb weight (kg / lb.):

Sedan

LS: 1261 / 2780
LT: 1267 / 2793
LTZ: 1318 / 2905
SS: 1302 / 2871

Coupe

LS: 1239 / 2730
LT: 1244 / 2742
SS: 1277 / 2815
SS Supercharged: 1327 / 2925

 

Is it different for each trim. seeing how they all have different engines..?

 

What would mine be, i dynod 232whp=2900lbs?? I guessing about 270 crank hp

 

yes it is about 270 crank hp

I don't understand my calculations...

270-14%=232whp

BUT

232+14%=264whp

wtf...

 

270 - 14% = 237 hp

 

Your taking the percentage of a smaller number, so it will be a smaller gain.

14% of 232 = 32.48 232 + 32 = 264

14% of 270 = 37.8 270 - 38 = 232

 

Simple math its the hardest
