These Are The Most INSANE Engines EVER

[@Dustrunnersauto]

I'd like to clarify that the Subaru F1 engine came before Subaru's dominant run in the World Rally Championship in the 1990s. The way the video was laid out made it seem the other way around. What other crazy engines would you add to the list? 👀

[@DBerwick]

Developed for Coloni F1 by Motori Moderni, the engine was under funded and under-developed. Subaru was brought in and bought the naming rights for the engine. Subaru played no real role in it's development. Subaru simply provided money to MM. The engine continued to be under-developed and the chassis it was in was terrible.

Should have covered Honda's V5, used in MotoGP It used a 75.5° bank angle and the rod journal for the center piston was offset 104° from all the others, perfectly offsetting the primary imbalances that a v5 would normally have

[@CruzanRastamon]

As a VR6 expert. Can tell you that the VR5 was made for those countries that insurance amount is based on your engines size. Hence why only a handful of counties had it. It was also short lived because soon after the laws changed. The power had nothing to do with it because Volkswagen was still using the 1.8t at the time that made more power and came in base model cars. The VR6 was designed to be a diesel.

[@haku1155]

If I remember correctly, both the base versions of 2.3L VR 5 and the 1.8T make the same HP and are only used in the GTI Model. There is a 150HP version for both and then the "upgraded" version with 170HP in the VR5 and 180HP in the 1.8T for the 25 year anniversary Golf Mk4 GTI. The 1.8T would just go a lot faster because the max torque range is higher in the turbo engine. The 2.3L would Rev higher and deliver less torque. The VR5 has some very unique and in my humble opinion pretty awesome sound and is beloved and hated by the VW following here in germany depending who you ask. It just doesn't really deliver as well as the 1.8T feeling wise. There is a saying about the VR5: You can hear it for a long time and you can see it for a long time.

[@CruzanRastamon]

@@haku1155 150hp, 185hp that came in special edition gti’s and the beetle S. 225hp that came in the Audi TT. Mind you this is North American as we never got the VR5. It was as 2.0L, 1.8t, and VR6 till the mk5 platform came with the 2.0t fsi. We got the diesel but it was the 1.9L TDI.

[@haku1155]

@@CruzanRastamonyea the GTI came in 4 Engine variations in Germany. Actually 3 but the 180 HP 1.8T is imho more like its own thing. V5 - 150HP rev1 and 170HP rev2 1.8T - 150HP rev1 and 180HP rev2 1.9 TDI. In the 1.9 TDI it was merely the interior and exterior line with the normal Diesel as the most powerful version had 135 HP. Much more interesting is the Polo 9N3 with the 1.9TDI and 130HP. That engine has lots of potential while being safely and easily upgradeable to almost 1.8T levels of power and stunning 300+ Nm of torque.

[@glennoropeza3545]

Thank you for sharing that Subaru flat 12 engine's history! Now I know! This engine was tried again in offshore powerboat racing with lackluster success! Edwardo Polli - a wealthy Italian financier- had a custom made aluminum 44ft catamaran powered by four of these turbo 2.9liter flat12 engines, each engine made 550hp! Four engines drove two razor sharp surfacing propellers! Like all powerboats this boat was fast and fairly reliable but didn't win any championships and lasted 3 seasons maybe 4? His rivals all used big 8 liter V12 Lamborghini gas engine, Chevy big block gas engines or big 9.8 liter Isotta Fraschini diesels or SeaTek diesels!

[@ellomirza]

All these little V8s would be perfect hybridized. Electricity covers low end torque then put drag on the motor at high rpm to charge the battery because you want to rev an engine out but you don’t necessarily need 400hp in a 55mph corner. Anyone could easily make this today it would be the perfect drivers car and cost $1.3 mil and of course no one would buy it LoL.

[@The-fs5wn]

The flat twelve could have been great in a dragster (albeit larger). In theory it is the most balanced engine there is. Perfect primary and secondary balance, with almost zero chassis stress since every force cancels out. With DOHC heads, triple the displacement, nitro gas and a TF level supercharger pushing the same boost psi as now, you’d have an engine that revs way higher, flows air better, has more displacement, and will sound better. With that much performance headroom, 13k hp would be viable and would last an entire event without the need for a total rebuild every run.

[@mickvonbornemann3824]

I assume with these small V8s, they can have flat plane cranks, which also means they can can fork n’ blade rods, which means each bank can be in-line with each other, meaning no stagger & thus no rocking couple & thus no 3rd order of imbalance.

[@ramseycattn5941]

What do you mean by fork and blade rods?

[@jiroyamamoto2878]

At the big end 1 rod is normal looking. The other rod big end is very wide and a slot is cut into the big end so the other rod will fit there. Harley Davidson's still do this. However neither of the V8's being discussed have fork and blade rods. This rod arrangement is no longer considered optimal.

Two Honda cbx1000 s6 engines would make a killer high rpm v12

[@rientsdijkstra4266]

What is important for acceleration and pulling power of the vehicle is the torque at the contactpatch between wheel and road. There are two ways of getting more pulling power at the road (which can be combined of course): 1.) increase the torque at the crankshaft ( = nominal torque of the engine), OR 2.) raise the rpm at which the torque is delivered. Why? Simply because the same torque at a higher rpm of the engine implies that a lower gearing and thus a higher multiplication of the torque in the transmission from engine to road can be used. So in the end it is the POWER (torque x rpm) and not the nominal torque of the engine that determines how hard it actually pulls on the road!
