100 hp/l NA engines
 

This came up in another thread. It's an interesting topic; let's continue the discussion here.

One from the past is BMW's S54: 3.2l tuned to make 315hp in the Z3 M Roadster/Coupe MY 2001-2 and 340hp in the E46 M3.


Are there others? Anyone know more about the engines listed?

I completely forgot about this topic (thanks for picking up the slack pal) ...

LFA's 1LR-GUE is a 4.8L V10 making roughly 560PS.

:happy0180:


Now to get some other people in here and get the discussion rolling... :D


edit: paths crossed, hi Guff! :)

Mazda RX-8

On another note, Honda isn't part of this list now…probably the first time in over 20 years!

They lost it.

No longer in production.

Dozens and dozens of Hondas from the past.

I thought the fq400 Evo 8's hold the record for most hp per l. I think they made 450hp for a 2.0 engine.

N/A only

Haha its looks like I had a brain fart reading the title.

Yeah. That's exactly the problem.

I seems that the high horse power small displacement N/A motor is going the way of the Dodo. If that's really the case it's sad because I like their rev happy nature but it's an entering achievement not many aspire to these days

I forgot to add an honorable mention which should have been on my list.

I know there might be other motors currently in production that that come close.

K20?

All of the current versions of the K20 are 2.3L so that motor misses the mark too...

"Current" Yes you are correct.

Not to split hairs of course... :D

And I think the K20A still lives in Japan? Not 100% on that one.

Went to honda.co.jp....no civic listed on their site, then found this:

"However, the story is much different over in Honda's home market of Japan. According to Nikkei, Honda sold only 182 standard Civics and 270 Civic Hybrids for the month of October. As a result, the company will stop the sales of all Civic models in Japan."....That was in 2010...guess I missed the boat on that one.

Audi RS4.
4.2L 450HP, 8000+ rpm
Last powerful NA engine from Audi??

Kinda funny. Audi went for NA in a big heavy 4WD car where steering feeling is not that great...

BMW who has been more dedicated for NA, straigth six, RWD only, steering feel and mostly petrol engines have focues max on turbo and "watered down" their core principles lately. I think they are doing the right thing on focusing on turbo engines in these days tough. As long as lag is minimized!

Im guessing turbo will be even more normal in the near future. After owning a 2010 Cooper S, I really start to like torque and power from down low combined with great fuel economy and a "minimum" of lag.

Even Toyota will start focusing more on turbo technology. Source

8000+ RPM in a angry NA is still the best car porn tough! :)

Lamborghini Aventador has a 6.5L V12 that makes 691hp.

Good catch!

:happy0180: BMW's S54 revs to 8500 and sounds sweeeeet! Car porn for sure!


Engines from the recent-ish past are also welcome in this thread. Especially given my bias for the S54 ;)

Yes seriously, the japanese market is so different from here. Not more civic sold (while it's canada's number 1 sold car), while the prius is the number 1 car sold over there.

But yea, as of 2012, Honda makes no more 100 hp / liter engine. :(

F20C

F22C

H22A type S

K20 (RSX type s)

B16A

B18C

2ZZ-GE

Scion Tc

The Scion website lists it as a 2.5L with 180bhp...

Man.... So close!

/o\

1975 corvette 5.7l and 165hp.....wait thats going least hp/l

Sorry, that's a 2.6L.

Anyways,

Hartley Enterprises also makes a couple engines that get put into cars like

they also have a couple engines in a thought phase, hopefully they make it to production

2 liter V8- 400 hp @13,000 rpm. Status: Project under consideration pending completion of agreement and technology study.
4 liter V10- 600 hp @10,000 rpm. Status: Project under consideration pending completion of agreement and technology study.


and then ill leave a pic of this 16 cylinder boxer engine here
http://www.italian.sakura.ne.jp/bad_...h16_engine.jpg

made 200 hp per liter at 600bhp, 3L engine

ohh yeah and that was back in 1966 :D


Weslake 250cc single-cylinder was reported to be giving nearly 40 bhp. - 158 bhp. per litre in 1965

Pretty sure we're talking about production engines for road cars here -_-

BRM H16 never ran a race (or finished?) I think.

Edit: FAIL, wiki says it won the 66 US Grand Prix .

the atom is a road car, and it is a production car, and its a NA v8 over 100 hp per liter, i just thought the H16 was cool because we have a boxer motor too

and feats like this were possible almost 50 years ago... that i also thought was pretty cool :D

actually it ran and won 1 race! used in a few races :edit

They make like 25 a year, I don't think that counts. The engine is close enough to one off at 30000 dollars or whatever. I think you probably could machine your own crankcase, crankshaft, cams, and wire up an ECU for less than 30k.

its 30k for the motor and 20k for the transmission :D

its been an after thought to put that engine in a FRS, when i get around to it ill make a build thread :D

Thanks for that. I didn't specify directly, but yeah, that was the implication.

I'll decree that the Ariel Atom squeezes in just under the wire - it's road legal, if only barely, and it's a way cool machine :happy0180:

edit: Plus @carbonBLUE gets bonus points for a great post with lots of info and fantastic pics :thumbsup:

Indeed! Getting somewhat off topic here, if you ever want to get completely blown away by feats that were possible 50, 60, 70 and more years ago, visit the Smithsonian Air and Space museum in D.C. They have rows and rows of engines (some cut in half for display so you can see inside) that span several decades of military aircraft. You can see before your eyes how piston engines were taken to the very limit of what's possible in terms of power output (and almost beyond) and how they then quickly gave way to a new approach in the form of turbine engines. The last of the reciprocating engines were as bizarre as they were problem-ridden, and several prototypes were scrapped after huge and costly R&D effort when the advent of turbine engines revealed that the old model had become a lost cause.

I don't think it's legal in the US, the brits are just crazy and let you drive that kind of stupid shit on the street. Yes, I'm jealous.
