9:00 An engine is not pre-heated to "maximize lubrication". A racing engine is pre-heated so that clearances and other dimensions are within design tolerances. When the engine is cold, due to negative thermal expansion some parts will be out of design specs. Even systems which do not require any lubricants may need to be run only at operating temps for clearance reasons.

[@slowanddeliberate6893]

The oil has to be warmed up as well.

[@Southghost5997]

Clearances for oil passage, less friction, and warmer, less viscous oil. It's all related.

[@flyingdutchmanindustries5877]

Weeelllll ... "Pre-heat" is essentially the same as warm-up, but without the run-time/parts wear time factor. It aids in lubrication by reducing the viscosity of the oil, allowing it to be distributed to parts quicker. ;)

@@danowens7145 From chat Chat GPT, "The engine from a Suzuki Hayabusa, without the running gear and accessories, typically weighs around 60 to 65 kilograms (approximately 132 to 143 pounds). This weight can vary slightly depending on the specific model year and any modifications or removals." It also said this, "The Suzuki Hayabusa's engine produces around 190 to 200 horsepower (about 142 to 149 kW) and approximately 150 to 155 Nm (about 110 to 114 lb-ft) of torque. These figures can vary slightly depending on the specific model year and any modifications or updates made to the engine." If you were to calculate the weight compared to power, the Nissan engine would thrash it, then again if you were to take the turbo off I've no idea what the power would be, I'm guessing 200hp+ from just 2/3 of the weight.

This video just seemed a bit confused, I never got what point it was presenting or what cool and interesting thing we were being shown. "Here is this high power-per-weight engine. A turbo 3-cyl making 400 HP and weighing in at 40 kg/88 lb. PS: it's a race engine and was never available to the public." I can think of another fairly light-weight three cyl that makes ridiculous power for its weight. The G16E-GTS from the GR Toyota models, which is a 1.6L 3-cyl making 300 HP in street trim, and capable of over 450 HP when custom tuned. Which is available to the regular consumer, and can be bought as a crate engine. "Here's an alternative high power-per-ton engine. It's also for racing use only and not yet available despite being in development for over a year and a half." At this point you might as well point out the JFC Racing Monobloc v8, which comes in two flavors, a twin-turbo 2.8L weighing under 300 lbs with the turbos, intake, and headers and producing 765 hp; and a naturally-aspirated 3.2L weighing in at 200 lbs with an output of 460 hp. Or any of Judd's offerings, or any of the half-dozen or so other motorcycle-derived engine variants made by various boutique engine manufacturers. Each of which will set you back the cost of a very nicely equipped sports car.

[@siraff4461]

Well apart from that weight being dry and without any of the ancilliaries such as that massive turbo and intercooler which it had to have to make the power (so in practice it was nowhere near 40kg), its also a one off billet race engine which not only costs a fortune but can also be designed to run on race fuel and not worry about any emissions regs. The reason we don't see things like that in road cars is because if you want 400hp something like a 2.0T 4 cylinder adds a relatively insignificant amount of weight over a 3-pot with the usual cast parts, is in a lower state of tuen so easier to get through emissions and longevity testing and doesn't need to be made of unobtanium to deal with it. When its in a car thats over 1.5t in the first place an extra 50kg for ease of manufacturing, cost, longevity, economy, emissions and all the rest is the obvious trade off. Oh and on normal fuel its not making 400hp unless its also making a lot of heat. More like low-mid 300's at best. This is why the Yaris GR engine is getting close to its limits too - 280hp is great but its also only about 50hp away from being right on the edge on road fuel and with road emissions equipment.

[@hendo337]

Motorcycles are going down to parallel twins now for emissions reasons, cars for four to 3 cylinders. The gap between the piston and the cylinder lets hydrocarbons past and ruins the emissions.

Before metric the cement base was nominally I cubic foot of cement and weighed 94 pounds. Now that it is metric it is 40 kg or 88.1 lbs in the old measurement.

I would love to see that engine in a Alpine A110R, to see if it would be possible to get the A110R to under a 1000kg. And VW never did make the sporting version of their XL1 did they. Just some thoughts, ceracoating the entire outside of the engine, for rust protection and from heat coming from the engine bay (turbo, exhaust, brake temps) would also allow for the oil to get warm and stay warm and just allow the cooling pack to do its job. Ceracoating the tops of pistons to stop heat transfer into the crank case and over heating the oil, would also mean that possibly a leaner burn, and having very little unburnt fuel left in exhaust gas. Of course ceracoating the exhaust from the head to the tail pipe as well as as much of the turbo that can be done. I did read about a diesel where they ceracoating the inside of the intake and combustion chamber to increase thermal efficiency. Don't know what that would do to this engine or application. But just some engine ideas I've been having, to try to increase thermal efficiency, increase mpg and decrease emissions.

Normal black steel has a tensile strength around 300MPa whereas a quality alloy can be 2000MPa and if you get exotic it can be 6000MPa so the wall thicknesses you are used to is just dumb cast iron 1930s thinking. done well it's just a thin shell around the pistons with negligible weight. same with the pistons, thin top hat, thin arms, well supported crank shaft. If it was any kind of sophisticated it would look alien. the term 'engine block' is a failure in itself. It could also have rocker pistons so there is no friction on the cylinder walls at all.

You may also want to look into the Toyota 503E 2.1L 4cyl Turbo, a purpose built racing version of the common 3S-GT 2.0L, with an increased bore (89mm vs 86mm) to accommodate larger valves to achieve better breathing from the cylinder head. It was originally from TRD USA and used in IMSA, but eventually made it's way into the JGTC/SuperGT Winning Mk IV Supras (Toms, Sard etc) in mid-90's Japan where it put Skyline GT-R and NSX alike to complete shame, considering what it was. It was not uncommon for it to produce well over 1,000 HP at the wheels for qualifying runs, then run around 600-800 for actual racing. It was eventually restricted back to 2.0L and the original 86mm bore after becoming too dominant and also handicapped with inlet/boost restriction. Just thought this engine might have also been interesting to you, since this was back in 1995.

No, the F1 BMW turbo did not produce 1500hp. Just because people keep saying it doesn't make it true, even if it is said by ex-F1 drivers with a fading memory. Some people agree that it made somewhere between 1300 and 1400hp in qualifying trim, with qualifying fuel. At one point, not even the BMW dyno could measure numbers as high as 1500.

But, as far as I understood that bit of automotive history, they didn't have the dyno tech and capacity to test at those insane power levels. The power levels were estimated based on comparison of lap times in qualifying trim vs. race trim. In the end the problem wasn't so much the power but the cooling. The 1400-1500 horsepower at, give or take, a third mechanical efficiency, meant that there was roughly 2 Megawatt of thermal load to be moved from engine block to outside air. That was impossible to realise in the F1 car package of the time. Those engines, when in qualifying trim, simply overheated after one or two laps driven in anger.

@@Hydrazine1000 Bigger heat exchangers could've been used in qualifying, plus fans for cooling purposes were still allowed, if I'm not mistaken. There was simply no need for the engines to last more than a few laps, therefore thermal stress and fatigue were taken to extremes. Sometimes teams got it right, other times the engines would smoke-signal their disagreement.

[@LegalEliminator]

i love the idea of small engines making big power. i loved it when the barra 6 showed up the big gm v8s, i loved it when the gr yaris/corolla showed up the STIs and Evos of the world with their 3 cylinders. if Nissan were to bring a similar engine to the production world, it could make a cool combo for a nismo variant of the current Z car if it were to be combined with a performance hybrid system. the lightweight powerful engine with an electric motor to assist would make for an interesting combo imo.

You forgot the Mazda Rotary engine. 240bhp from 1.3 L, naturally aspirated.

[@SazanD1]

Not an apples to apples comparison as the rotary guzzles fuel at the rate of a big block V8

[@aranykai]

1.3L rotary is not equal to 1.3L in a piston engine. To make that 240bhp, you're moving fuel and air equivalent to a piston engine twice that size. 240bhp out of a 2.6L NA V6( a 2 rotor has 6 'chambers') is much less impressive.

[@Kowalamaster]

I think it is disingenuous comparing the V10 and V8 screamers, as they are Naturally aspirated where as the BMW is a closer representation being that it and Nissans are both Turbo Charged / Forced Induction. People have taken honda B and K series to near the 1500 hp range like the BMW, and they were also Turbo Charged.

[@deanjdk]

Why disingenuous? It's a discussion about Hp per kg of engine weight. Completely legit comparison for the points being made

[@lorddoobsworth144]

@@deanjdk Yeah hp per kg is much better than hp per liter, as an engine with much more displacement can be lighter (depending on engine design and material). Either one only takes how much power the engine makes at a specific rpm into account though, when an engine operates over a range of rpms.

[@raydreamer7566]

I like the 4 cylinder for aircraft usage. 400 HP for take off then dial back for cruse. It could also be mildly turbocharged to maintain HP at altitude...

The Koenigsegg Gemera is equipped with an unusual three-cylinder combustion engine called the "Tiny Friendly Giant" (TFG). It has an engine volume of 2.0 liters and produces an impressive 600 horsepower. What makes this engine special is that it is turbocharged and uses Koenigsegg's Freevalve technology, which eliminates the need for a traditional camshaft.

Like the Yaris 3 cyl, people are getting 888hp from it at the wheels, but that isn't a daily driver. But for the weight 400hp, 40kg as packaging is nice to work around.

[@michael2nicolaisen]

In 2003-2005 the best F1 V10's was around 940-950hp and weight around 84-86kg. So F1 V10 was around 11hp per kg and not "only" around 8hp/kg

[@bdhale34]

I think you may be a bit mistaken about the issues being caused by 24 hour use, the gearbox lasted 6 laps it didn't make it a half hour, what this car's gearbox issues boiled down to is 20xx Nissan transmissions, was probably a cvt and all of Nissan's CVTs back then were reliable until the first oil change if you got lucky.

Kawasaki H2 engine puts out about 192 and *can* put up to 250hp and is a 1.5L inline 4 cylinder turbo that weighs around 62kg fully dressed up.. and that could probably be reduced quite a bit given you don't need an internal transmission or clutch so you could make it a direct-drive. I have seen some attempts at using motorcycle engines in cars and they typically lack torque but the H2 torque figures are decent at 123 ft/lb... so not extreme numbers but very light-weight.

[@Finite-Tuning]

Very cool, thanks for the info. I had no idea that little thing existed, until you told me. Cheers 🍻

[@rich7447]

With peak torque at 280 lb ft, the absolute minimum RPM that it would need (if peak HP and peak torque are at the same RPM - which almost never happens) is 7,500 rpm to make 400 hp. According to several articles on this, the engine redlines at 7,500 rpm.

[@theelmagoo]

I always wondered what became of this project as it had a lot of promise!! One other modern day engine that also comes close to it is the Koenigsegg TFG 2.0L engine in the Gemera. 70kg @ 600hp gives it 8.57 hp/kg.

[@LSturboguy]

couple of questions, 1. how much hp does it make without the turbo charger ? 2. what is its headroom for expanding hp ? 3. how much torque does it make? 4. what's its reliability ? really banging on about hp when its the turbo carrying the load isn't really 400hp, is it flat out at 400hp and isn't viable in racing, 3 cyl wouldnt be making very much torque and it is more important than hp, how long can it keep up in a long race squeezing 400hp from small engine usually become a hand grenade, is that why it never went into production

[@petercandance2330]

I'd put it in a Honda Jazz/Fit chassis, the second US generation 2009-12. It has the most rigid chassis, great handling, and amazing cabin volume for a subcompact lightweight car. The engine would be perfect coz the Jazz/Fit has a small engine bay space. If I wanted a sports car instead of a daily driver, Mazda Miata ist two generations, also for it's handling.

[@tyrefiretv2908]

One could state that Nissan wasn't wrong, looking at the latest 3-cyl. engines from Renault, Ford and Stellantis being used in their Rally 5/4/3 models, with outputs between 170 and 220hp, basically road-going engines tuned for racing but still very reliable, with services quite far apart.
