From a logistical standpoint, how do we move on from the straight six engine? Is it possible for engineers to improve on such a perfect platform?
8 cylinders in a 90 degree V angle
already did
The v6 obviously
That's why the gtr has one instead of an oversized boat anchor l6, or the new Ford gt which replaces a shitty v8 with God tier v6
>>15229950
but muh torque and single exhaust
>>15229950
>dat god tier 60° V6
GM just can't compete
>>15229935
Boxer 6
>>15229966
but GM has made 60 degree V6's for like 40 years now.
>not making 130hp from a screaming V6
>>15229974
>not radial 6
>>15229988
didn't they have radian engines that rotated with the driveshaft, spinning around a central static shaft? get four of those and make wheels around them
>>15230019
>radian engines that rotated with the driveshaft
wouldn't that not move the driveshaft at all
>>15229935
i6 makes more torque than v6, which makes it good for trucks and shit
plus, v8>v6
>>15230034
the shaft to rotate the wheels isn't being propelled by the engine, just mounted onto the center of it. the assembly spins around a second shaft attached to a vehicle.

for reference
>>15230039
Cylinder configuration has no impact on torque.
>>15230069
with an I6 you get a longer stroke so that means more torque
>>15229946
Does a VR6 swap in an AE86 exist? I think it'd be interesting
But we already have the I5
>>15230093
just make the V6 bigger, and use really skinny front tires to give it room
>>15230069
Wrong
>>15230102
Understeer
>>15230069
Found the retard
>>15229986
Sorry, I meant hand built 60° V6 in a hermetically sealed workspace that's turbo charged sequentially by a twin setup, powering one if not the most advanced all wheel drive setup in the world
Seriously, GM can't compete
>>15230135
mid engine and a fat ass then?
>>15230145
Or just an I6
>>15230145
>I4 turbo
I can only dream ;_;
>>15230148
Eh, if only Tommy Kaira brought back the ZZ for a final run
>>15230069
This is correct
>>15230093
Stroke has absolutely no restrictions based on engine configuration
>>15230124
>>15230136
You are wrong.
____________________
Engine moment (torque for ... simpler people) is based on air combusted per cycle, which for NA engines is ANALOGOUS to engine displacement. See graph. Graph is my collection of a few hundred engines ranging from single cylinders to V12's.
>>15230212
I wonder what the ones above the mean line for lb/ft per cc do better? shaping of air channels?
>>15230212
So, if you want to play a game with this graph
If you have a NATURALLY ASPIRATED car:
Take a calculator
0.0762 x (Engine size in CC's) - 6.9
See how bloody close it is to your manufacturer rated lbf-ft torque.
>>15230227
Lines from the origin trending upwards are what's called BMEP. The mean line is the average engine's BMEP. It's around 11 bar (unit of pressure). An F1 engine will see ~14.3 bar. A NASCAR Cup engine will see ~14 bar. A Honda S2000 will see ~12 bar.
A high BMEP means you're inducing more kg of air per liter of displacement per cycle.
>>15230229
So, some examples
Corvette LT1: 6162cc
Formula guesses 463 lbf-ft. Chevy rates 460.
Honda K20Z3: 1998cc
Formula guesses 145 lbf-ft. Honda rates 139.
IT'S FUCKING MAGIC GUYS
>>15230273
Engines above the formula's guess have a Break Mean Effective Pressure higher than the average of the few hundred engines I averaged. Engines lower have a lower mean pressure.
Mean pressure is comparison of (basically) kilograms of air induced verses volume of induced air. More air in the same space = more torque = more power.
>>15230227
So on that, to achieve a high(er) BMEP, you need to do more things right.
Most "street" engines are crippled from ever achieving competition levels of BMEP due to:
Poor engine bore to valve area ratios
Poor cylinder head ports to valve areas.
They're both usually way undersized to make the engines drivable. No amount of bolt-ons will get your average engine above 13 bar BMEP.

I6's are known for smoothness and response, bench racers wouldn't know
>>15230421
not a fan of that star arm thing, looks like a lot of wear.
>>15229942

When will i6 turbo be the new normal?
>>15229935
An I6 block with 6 rotaries instead of pistons. Longevity+ultrahighrevs
>>15231188
Double dubs never lie. It will happen
>>15229935
60 degree v6
>>15229942
>90 degree v angle
isnt that just an L
L8 when
>>15230069
This.
>>15230124
>>15230136
I know it's already been said, but you two are so incorrect it hurts.
>>15230039
I6 configurations lend themselves to commercial applications, not for their ability to produce more torque, but in order to help balance the rotating mass of an engine large enough to achieve the desired output.
Ironically, one of the smoothest highway trucks still sold today is powered by a V6...
>>15229942
This.

Inline sixes were made redundant over two decades ago.
>>15229966
>>15231774
>trucks still sold today
Even back in the day, the GM truck V6 shat all over the I6 offerings in other light trucks.
>>15230100
No but it does swap into a corrado perfectly
First new engine patent in 30 years (all others have been slight variations on current engine patents). I'd like to here thoughts on this.
https://www.google.com/patents/US20110162599 oops, heres the patent link.
![TAS-2014-0121-1200x800[1].jpg](https://i.imgur.com/zNx0V53.jpg "TAS-2014-0121-1200x800[1].jpg")
>>15232740
know what else fits nicely?
>>15233124
>>15233126
So it's just a radial engine with two cylinders?
Acts pretty much the same.
Also what about the Duke Engine?
>>15231780
neat
Not exactly, a radial engine is very different. On this engine the pistons rotate around the bore while the bore is rotating the opposite direction. This Counterpoise Engine can have 16 pistons if need be, the patent shows 2 because the HP is similar to a 4 piston OTTO. The Duke over-hypes, and under-performs...
