I was watching hi-rev tuners on Sunday and a quiz question came up before they went to a commercial.


The question was "What production engine produces the most hp/liter?" I was happy that they were going to display the rx7 because all they ever show are stupid hondas. So turned on my tv-tuner to record the answer. Here is what I got...

Ok... let's see

S2000 240/2 = 120 hp / liter

well

FD 255/1.3 = 196 hp/liter


WTF!!!!!

Well it's ok 'cause the girls name had POON in it!!!!!

keywords here are "production engine"

I've made note of this before (while the 13B-REW was still being made)... in the Lounge where it belonged.

Hi-Rev Tuners needs to DIE.

HOWEVER this time they're correct. The 13B-REW isn't a production engine anymore. The last were made in October(?) I believe.

Wait for the Renesis...

Icemark

This should be in the lounge or automotive forums

can it be moved or deleted then?

13B-REW is still a production engine. Just because it's still not for sale in a car doesn't matter.
Production engine means that the engine was available to any consumer on the market.

The S2000 has the highest hp/litre of current, normally aspired, production engines.

The NA FC S5 rx-7 made more HP per litre.
Just wait till spring and the RX-8, then they can shut up about the S2000's hp/litre title that it claims even though there are cars out there 15 yrs older than it that do better hp/litre numbers.

There is many posts already about this.
Happy new years.

yup

and yes, High Rev Tuners does need to die. That blond girl need to get bent over

jmseven

They were talking about US sold cars.

jmseven

I second that. The show sucks ***.....

That dumb *** guy that interviews and comments on cars, he needs to take speech class. He keeps stumbling his words........everytime he talks, it just pisses me off.

The girls on the other hand....who gives a ****. They both look allllriiiggt..just need bigger .

Blowtus

they needed to say naturally aspirated...

Agreed with Icemark

I would argue it depends on how you want to define things. Really you have to 2x to compare the output of a rotary so a renesis or 13B-REW gets ~100hp/L. Posche 959 did 158hp/L, F40 163hp/l. If you want to talk efficency of size then ofcourse the rotary wins. I'm not phrasing what I'm trying to say correct, but the point is there's merrit to the rotary given the 2X correction and there's also merit to saying it's better than even that S2K's engine.

Drop the "oh it should be 2x more than it is because of how it functions" argument. Displacement is displacement, dont hate on the rotary because it has a better output

adamlewis

Uh...Its a valid arguement.


When calculating the displacement for a LS1, would you leave off 6 of the cylinders?

MasteRX

It doesnt matter. The 13B is rated at 1.3Liters because that is how much displacement both of its chambers use during a combustion stroke. Just as a two stroke engine is rated at 250cc or whatever. Saying "lets be fair about it and double it" or whatever is a mute point if we are talking about engine ratings and which engine gives the most HP/Liter.

Because the fact is, the rotary owns in that area. The high HP/Liter is the whole beauty of the rotary in the first place! So let the boys at Honda bask in the engineering glory of creating the current HP/L king. They will be owned by RENESIS soon enough.

By the way, Hi-Rev tuners don't know dick.

yeah, i saw that too, when they asked the question before the comercial break, i was like "sweet they are finally going to talk about rotaries, the answer is rotary engine".

Then they told the answer and i was like....rrriigghhtt

adamlewis

Uh...An LS1 doesnt fire all 8 cylinders in one combustion stroke ( which would only be 180deg rotation of the crank... ) but its still rated as a 5.7 ( the volume of ALL its cylinders added up )



By the way, you dont know dick.

dr0x

If those 6 cylinders used one combustion chamber, yes.

adamlewis

Before I go any farther, let me ask you; How many combustion chambers are in a 13B-T ?

Steel

wait a second, im getting lost. Is the argument here something along the lines of "because the rotary is weird, it should REALLY be 2.6 litre, because blah blah, combustion chamber total this and that" accounting for ALL free space? Its 652x2 cc's which is 1304cc's total combustion volume. I didn't know they started counting other strokes. ... so, if im getting this right, then all you guys that say the rotary should count 2 times, then i guess a 5.7 litre should REALLY count as an 11.4 litre, because well, dont forget about intake.

I dont see how there can be confusion here. Spell it out for me.

*edit* and oh yeah, the S5 NA FC made 123 hp/litre, still beating out the s2k. I never saw Hi Rev tuners, but from what i heard, its so bad that you can't even laugh at it.

Steel

I didn't know that firing order had an effect on combustion volume. Hmm...

Funklord

i have to say.... displacement is displacement. being able to combust once instead of every other time is just a more efficient design, just like a dohc honda super deluxe vtec or whatever is more efficient than a ohv pushrod iron v8. basically they're trying to say the most efficient engine design has the most hp/liter. so the rotary wins... no 2.6L crap. its a more efficient engine design (in terms of displacement). turbo or not, the later 280hp fd's had 215hp/l, and the rx8 has 190. so in terms of comparing n/a to turbo, unless they come out with a 391hp n/a s2000 or a 430hp turbo s2000, rotary engines still get better hp/liter. and thats that.

adamlewis

What in the hell does all these strokes have to do with anything?


When the LS1 is rated at 5.7, what does that mean?
It means that volume of all the cylinders ( combustion chambers ) added up equals 5.7 liters.

So...I ask again, how many combustion chambers does a 13B have?
