Your favorite engine layout?

[LateNightCable]

That Mazda 4 rotor sounds like a chain saw. I would'nt call it beautiful music, but it definitely has spunk.

If I were to choose one engine to have for all time, I would go with a big torquey American V8. It sounds right, it's simple and rugged, and I love the feel of an engine that has real grunt, right off the line. An old Cadillac V8 would be nice. I'm old fashioned at heart.

my favorite, the torquey and windy bimmer m-power straight six. the best being the 3.6l and 3.8l m5 e34 engines. i want to build a cobra kit car. that's what i want under the hood!

[LateNightCable]

A Cobra kit car with an M5 straight six? Prepare to recieve some odd looks.

I like my V-8 up front with rear wheel drive

[thepolarfoxqx]

i don't care, it'l be fast. If i have a hard tuned 3.6L I6 in there, say pushing 450hp, maybe a bit more, the I6 is lighter than the big iron pushrod V8s normally put there, i'd say that thing would purr. it'd be great. I'd put a getrag type-d tranny behind it, i'd have the best of everything going for me.

and yeah, the V8 front engine rear drive is verssatile and a lot of fun.

btw, ever tried dougnuts in a mid-engine car. that is quality shit!

[jterp]

nothing like the sound of a big ol' 426 hemi.

I prefer flat engines. I think more cars should have them.

F4

F6

F8

F10

F12

These are some of my favorite things.

[thepolarfoxqx]

flat engines definately have perks, but they do have important draw backs. The lube system is a lot more complicated because the engine lays flat. They are more expensive to make, and they are freakishly wide.

[LateNightCable]

Aside from lubrication complexities, if they can realistically fit a flat engine into the nose of an Impreza, which is a narrow car - and still make the steering and suspension components strong and capable. I suppose being freakishly wide doesn't have to be much of a drawback.

Does anyone know of an L-head flat motor? That would no doubt cut back on the width of the whole arrangement.

[tallwingedgoat]

I had a similar discussion in another thread. I think flat engines would be best combined with Cross Rotary valves, that should solve the width problem and have other benefits as well.

L-head horizontal eh, interesting concept.

Hallo IwishIhadadiablo,

 

schau doch mal hier zum Thema Zubehör für Andere Automarken (Anzeige)? Eventuell gibt es dort etwas Passendes.

[thepolarfoxqx]

l heads have severe drawbacks. Flat engines with rotary valves would be a concept though. i realize on paper, the flat engine is the best, but in practice, i have trouble faulting inline sixes when compared to my flat six.

[tallwingedgoat]

I6 is a great engine, the only problem is the inline configuration doesn't lend well to scaling. You've got I4, I5, I6, and that's it. Anymore cylinders and you have to go with a completely different V configuration, different crankshaft designs, different balancers, different bank angles, double your cams etc.

With flat engines its possible to design a whole family in one get go. You learn how to work on one, you know them all. Too bad nobody is doing it.

Imagine this thing under your front hood.

[thepolarfoxqx]

i actually have a design of inline of my own, it scales very very well. not strictly and inline, but there is a future for the layout, i promise it.

[LateNightCable]

An L-head flat motor could be made high performance. Build it just like any other high performance motor. Light componants, free breathing, large valves, individual throttle bodies, traditionally placed spark plugs. It could work.

[Kevin321]

There is nothing like that BMW s70

Mclaren F1 engine. I would pick it

over every over v12 ever made.

[LateNightCable]

Kevin, you're very into " absolutes " aren't you ?

Pretty good choice for a V-12 though.

[thepolarfoxqx]

over EVERY V12 EVER made you say?

shall i dig out one that completely blows it away, how about the centauri V12? better yet the Lotec tuned twin turbo Mercedes 6.0L pumping 1,334hp?

[ets]

What do you mean with a L-head flat engine??

By the way i read that Koenigsegg wants to use a flat-twelve if they were going to produce a new even more extreme supercar...

[LateNightCable]

L-head flat engine, meaning the cylinders layed in a " flat " arrangement, like a Porsche flat-6 or Subaru flat-4, but with the valves positioned to the side of the cylinder ( L-head ) rather than directly above ( Over Head Valve ). This way, the motor could be a good deal more narrow, with the valve train out of the way.

[thepolarfoxqx]

the problem is you loose combustion efficiency with flat heads. You're better off sticking to conventional head layout.

[LateNightCable]

I would think the position of the spark plug would have more to do with combustion efficiency than where the valves are. Besides, if there were any loss of combustion efficiency, it could be compensated for with free breathing heads, and manifolds.

Like mentioned above, L-head with traditionally placed plugs.

[thepolarfoxqx]

nope, less flow through the valves. the position makes a world of difference. i've taken classes on combustion dynamics, asiide from all of the painful calc, i can tell you, a side valve engine is an inferior design in terms of efficiency.

[LateNightCable]

Yes, it may not be as efficiant as OHV, but with free breathing and a set of big ass valves, I think an L-head could still deliver. The whole point would be to make a boxer more narrow anyway.

[thepolarfoxqx]

i'd sooner make room that switch back to side valve. they are even phasing side valve out of lawnmowers. You can buy a honda lawnmower that is SOHC. I couldn't stand driving a car that was side valve and mowing my lawn with something OHC>
