My friend insists that this isn't true. But i know Super Street had an article about it, and I am sure someone has read something too. I just need a link to something that proves this. The bet is worth 2 cases of Corona, so please help!!!

Not to mention simple elementary school algebra.

HP / Liters = specific output = 120 for the S2K

Just tell him to do the math, and let you know when he finds a car with a higher number.

Well, for an N/A engine it is, I dunno about forced induction....

 

there are plenty of forced induction motors that can meet that mark, but only the exotics can come close with NA powerplants.

 

Actually, a lot of STOCK production turbo cars don't even come close to that mark, because they don't rev that high, and their power falls off toward the top end with restrictive/quiet exhausts. Even the 300hp Supra and 300ZX TT's only had 100hp/liter.

And don't let him get you on rotaries. They don't count the same way, because they fire twice as often, or something. So you have to count an RX-7 as a 2.6 liter instead of a 1.3 if you really want to compare.

grippgoat said it all

 

Dang, I was about to mention the Rotaries too...I'm gonna do it anyways :D

<U>Naturally Aspirated Rotary</U>
2nd Gen Rx7, 160 HP 1.3L = 123 HP per Liter

<U>Forced Induction Rotary</U>
USDM 3rd Gen RX7, 255 HP 1.3L TT = 196 HP per Liter
JDM 3rd Gen RX7, 280ish HP 1.3L TT = 215 HP per Liter

Oh and as far as the most HP/L for Piston'ed FI motors how about the JDM Scoobys and EVO's? arent those car in the 280 ps/hp league with 2.0L?

and because Japanese auto makers have their "gentlemens agreement" it may be possible that the numbers are actually higher.

so thats between 140-160 HP per Liter on Boxer-4's and Inline-4's.

the next RX-8 is supposed to be 250 hp and that will still be the usual displacement (1.3L) 2 rotor Wankel engine.

You would have to state the S2000 is the highest horse power per liter engine naturally aspirated piston engine.

 

of any piston engine maybe yes, but the original poster said what car has the highest HP/L of any productions car.

 

silly riceboy

 

you are kidding right? if you were right? why didn't mazda used the 2.6L instead of 1.3? are they WRONG?

also, here is something you need to read...

Engine displacement is determined by first calculating the volume of one cylinder. "Volume" is the amount of air/fuel mixture that is needed to fill the cylinder. It is determined by the cylinder bore and stroke. "Bore" refers to the diameter of a cylinder. "Stroke" refers to the length of the piston travel between top-dead-center and bottom-dead-center. This volume, multiplied by the number of cylinders, determines the size of the engine, or displacement.

also, the rotary engine fires 1 sides of the rotor per each time, but within the same rev. the second one fires as well...but keep in mind, one revolution...for piston, only half of the pistons are fired

here is an illustrate of the engine at work...

I think th whole misconceoption with the whole 1.3L = 2.6L is cause of the way the Rotaries combustion cycle works. Something to do with the fact that each rotor side is like a stroke, so a 3 sided rotor is like a 3 stroke motor. so for a 2 rotor that wold be 6 strokes or the equivalent of a 6 cyliner V6.

It was in Mike Ancas book "Mazda Performance handbook". same thing with the displacement thing, usually this is how the RX7's are classed in Auto-X or Drag events...as 2.6L V-6's.

 

yah i have to agree....
Honda should have specified more clearly, because obviously even the more exotic cars, ferrari etc etc arent production cars.
Hey, i cant bang the s2000, alot of power per liter.

 

Ferraris aren't production cars? What does that mean? They made around 10,000 F355s...doesn't that qualify them as production cars?

 

Ferrari's most definitely are production cars.

 

Which Ferrari has a higher specific output than the S2000? The highest I read was around 110 hp/l.

 

none

 

The S2000 has the highest HP per liter for a N/A car...plus it has also one of the fastest piston speeds, up there on par with F1 engines...

 

Maybe for a normally aspirated car but the Evo Lancer is listed at 276 hp from 2.0L
and ive read that it actually makes around 300. Do the math 138hp per liter.

 

Actually I think the Nissan 1.6 neo vvl motor tops out at 125hp per liter N/A. Its rated as 205hp out of a 1.6, but only came in japan and recently imported into America for swaps in Sentra/200sx/G20.

 

Hmm, never heard of it, of course there are a lot of things from Japan that I never knew existed.

 

Apparently no one reads the previous replies before posting anymore Altough the S2000 may be faster than the 2G RX7 FC (NA) the RX7 still has it beat by 3HP. I havent even mentioned the JDM version of the 2G RX7, and as we all knoiw the JDM versions usually have slightly higher HP.

 

S2000 Engine: 5300 ft/min
F1 Engine: 9291 ft/min at least (this was in 1996 on a Ford Zetec-R)

F1 engines spin up to 17,000 RPMs at least, so if you meant engine speed it still wouldn't make sense.

 

I meant to say one of the fastest piston speeds of a production car..up there on par with F1 engines..unlike other engines.. and not rotaries...
