I got bored, so here's power to weight of like 20 cars.

[naed240sx]

05 Corvette: 7.998 Supra TT: 1005 350z: 10.699 Camaro Z28: 10.805 NSX: 10.995 300zx TT: 1105 Mustang GT: 1102 S2000: 11.799 Mustang GT: 12.304 RSX type S: 13.695 Integra Gsr: 14.901 Jetta Vr6: 15.895 Civic Si: 16.993 240sx coupe: 17.405 Civic Si: 17.498 240sx: 17.895 Celica GT hatch: 17.990 240sx sohc: 19.395 Mr2 N/A: 19.788 Integra: 20.896 Civic Coupe DX (your average ricer): 21.3

These are in terms of lbs/hp. All calculated using consumerguide.com, using the stock hp at the flywheel # and curb weight. Found it kind of interesting to look at after finishing. Gives you a better idea of how fast a certain car would be using two different values. Too many people going around saying that a 300 hp car is faster than one with 200.

"90 240sx sohc: 19.3 93 240sx coupe: 17.4 98 240sx: 17.8"

So the SOHC 240 is lighter than the DOHC 240? Is this just because of the extra weight from the DOHC parts or are there changes in the rest of the car. It seems like SOHC engine weight vs DOHC engine weight wouldn't make that much of a difference.

Also, is the S14 lighter than the S13?

99.9% of the time, they would be right

[naed240sx]

What are you talking about? Yes the sohc 240's were slightly lighter, but the s14's are alot heavier. The numbers mean how many lbs each horspower must act upon to move the car. The lower the better, because we all know that the less weight you have to move, the faster you can move it. The reason for the differences between the 240 years is weight for the s13/s14 and power for the s13 dohc/s13 sohc. Does this make sense?

[s13EastTN]

I thought s14's where like..50 lbs heavier than most s13's?

[naed240sx]

yeah, but #s are correct. www. consumerguide.com

Yeah, how often does a car with 300HP weight more than half again as much as a car with 200 HP?Very rarely.Some of those numbers arn't exactly right, for example, an 04 RSX-S weighs 2778lbs, and has 200 hp. That's a 13.89 ratio.The 99 GT Mustang weighed 3237lbs, and had 260 HP, leaving a ratio of 12.45... etc, they're a bit off, nothing major.However, what I think is the most impressive FF car I wouldn't have previously considered, the 7th Gen Celica GTS - 13.8... 2500lbs and 180HP, not too bad, considering how cheap it is.It seems like they have potential...I wonder why they aren't more popular with the tuners...

[GhostDriver]

Power-weight ratio is often overlooked. I think it's the best form of bench racing.

[naed240sx]

Yeah celica gt-s were sweet cars, 200 hp certainly isnt bad. I guess they arnt that popular, because they were old and only made in pretty limited numbers. No aftermarket. My friend almost bought one with a swapped turbo, said it was pretty fast. And yes, cars making alot less horsepower compete better than expected pretty often. My friend has taken out gt's in his jetta. Did anyone see that top gear where they pitted an evo against a murcielago? Evo kept up no prob, went even better through the turns. Evo's cost like what? 1/4 of the price and have like 200 less hp, 1/3 the displacement

05 GTM 405hp @ 2250lb = 5.55 (My next car)05 GTM 350hp @ 2250lb = 6.4205 350Z 287hp @ 3188lb = 11.10 (My bro soon to be TT with over 500hp)04 350Z 287hp @ 3188lb = 11.1098 240sx 155hp @ 2800lb = 18.0697 240sx 155hp @ 2859lb = 18.4496 240sx 155hp @ 2813lb = 18.1495 Maxima 260hp @ 3000lb = 15.78 (Sad my mom's car beats most of you)95 240sx 155hp @ 2754lb = 17.76 (My car when stock)95 240sx 256whp @ 3150lb = 12.30 (My whp w/ me in car and full tank)

I just dynoed at 397.5 whp (that would be 496.87 at the crank with 25% drivetrain loss). I drive a 93 coupe, probably 2900 lbs. That would be a power to weight ratio of 5.83 pounds per 1 horespower!!

[naed240sx]

wow very impressive

[Colton]

Thanks! Were going for 450 whp (562.5 crank hp) @ 20 psi in two weeks (waiting on a new wastegate). It's kinda scary when you can feel the car twist after dumping it to third and mashing the throttle on the highway!

[naed240sx]

So how long do you expect an sr20 to last at that level of tune? Is it fully built?

looking back^ this thread is getting a little sidetracked. Doesnt bother me but if somone wants to steer her back go for it

[Mixmastamunkh]

those RUF porsche's gots t3h MAD pwr. it's like 8, but could easily be more like 5.

Without power to weight ratio, nobody would care about the Lotus Elise!

2005 Lotus Elise: 10.4

[naed240sx]

Yes, exactly my point. a 200 hp car can whoop *** like none other. I swear im buying one when after I graduate. or maybe an nsx. Those are my top two cars. Even if i cant afford to have it as weekend only car, i guess ill just have to suffer driving it daily haha, but ill be loving every minute. Ei

[Red-KAT]

well if you take me and my fuel out of the car.

3150 total - 230 (me) 17gal fuel at 6.3lb per gal -107 = 2813

256whp + the 25% drivetrain loss. = 320hp

95 240sx 320hp @ 2813 = 8.7906 (Mine)

04 Z06 405hp @ 3118 = 7.698705 C6-Corvette 400hp @ 3245 = 8.1125

[Dattebayo]

You dont lose 25% to drive train loss, you guys.

As far as i have read, that figure is way off. I understand it to be more like 15% or 16%. Geez.

[spanishricer]

A 25% loss through the drivetrain might be accurate while stock (most dohc KA's put down around 120whp or so while stock) but don't think that it applies while making way more power over stock.

For instance, a car that makes 375whp isn't going to make 500whp at the crank. That's just insane.

[naed240sx]

agreed . its gonna vary

[Veriest1]

Drivetrain loss will also depend on viscosity of drivetrain fluids, how heavy your wheels are, clutch, and rotating masses in the drivetrain, etc.

So yeah, it's going to vary a lot from car to car.

[Bruno240]

i did the exact same thing when i was researching cars. I used the same formula to compare cars of how they would compete with each other.

I know my miata is 19.7 tho but its still a lot of fun to drive.

And the NA MR2 is also pretty high but is also a blast to drive also.

the celica ALL-TRAC was the turbo charged version with 200hp (same engine in the MR2 turbo i believe) The GT-S was just a GT with luxery options. It was also called the GT-4. It featured a hood scoop. And are all wheel drive They are pretty rare. If i ever see one for sale i would probably buy it if its at all possible.

[JimmyMethod]

See, you guys are thinking of the 5th and 6th gen Celicas.The 7th gen, the most recent and the one I was refering to, is the one with the NA VVT-i 180 Hp engine.(I'm actually pretty sure its the same engine in the Elise)

[naed240sx]

But from a performance standpoint, the celica hasnt come very far, considering that It once came with a turbocharged 200 hp/200 lb/ft engine, and was much lighter. Yes, it is the same engine, only tuned to a higher level of performance for the elise.

[hannibal]

The Lotus Elise awesome. It uses the same 180hp Celica GTS motor. J-Spec Tuner hooked me up for a ride at an AutoX event. That car handles like it weighs 10lbs.

95 Maxima 260hp @ 3000lb = 15.78 (Sad my mom's car beats most of you)Modified by Red-KAT at 4:29 PM 7/29/2005

Just noticed that you put the maxima has 260hp, which is incorrect. I have a 1996 Maxima 5-speed and all the 95-99 engines are the same 3.0 L V6 and come with 190Hp and 200 Tq. =). Not your average "grocery getter". This engine coupled with the 5-speed transmission = a lot of unsuspecting drivers getting a nice little surprise.

[JimmyMethod]

They didn't lable it the 4DSC for nothing.
