Why don't all cars have forced induction?

>>16172243
In practice it has been shown to worsen fuel economy because normies can't stand off boost. Also, cost. It costs a manufacturer basically the same money to make a 1.2L or a 2.2L I4 block, but it costs more to fit the 1.2 with a turbo.

Ok
>Doesn't effect efficiency of the engine
Yes it does. Drastically

I'm sorry but I'm twin screw poopercharged, is it still considered a spool cause it's not a centrifugal?

Turbos suck desu, not worth the expense

Some people want cars that can make it to 200k miles without multiple engine rebuilds, that's why.

Might as well make the engine properly in the first place instead

My car is at 212k and has had zero engine rebuilds. Still going stronk.

that means it was rebuilt before you bought it

Come back when a twin turbo v8 from Germany still can't match a fucking truck pushrod engine in reliability, efficiency, and power

>more power without changing the dispalacement
You realize it technically increases the displacement? It shoves more air into the cylinders, so a 2.0L engine can fit 2.5-3.0L of air
>doesn't change the efficiency of the engine
Yes it fucking does
>mad spools
Aayyyy he's got a point

>>16172736
Nope. Sorry mister shitposter. Any engine will last if you don't beat the piss out of it everyday. As I said before. Original turbo. Original engine.

this

>>16172243
some problems

the impeller spins so fast as 150000 rpm
this puts allot of stress on the bearing esp fluid bearing
further more parts of the bearing can make their way into the engine oil and air intake

the turbine side of a keeps the manifold and one side of the block a bit hotter
this when combined with over boost due to bypass valve fail can make pre detonation more likely

some newer types with roller or ball bearings and water cooled housings reduce this somewhat

>>16172817
I'm sure it lasts longer than your attention span gramps.

forced induction is a cheat that's tailored to the epa drive cycle. when consumers use it they're going to be in boost and that will suck down fuel.

>>16172986
is it a 240 volvo? those things are awesome
>>16172559
hurr durr, no replacement for displacement amirite?

>>16172318
So, it's a matter of cost. If you want to go fast, then a 4 banger with turbo still seems like the most economical option.

is this an ecoboost thread?

epa needs to fix their testing to reflect how people actually drive in the real world

Yeah... the 100hp @ 3psi engine in your Volvo doesn't really count. Squeezing almost 200hp from a 1.4 liter modern aluminum engine is a little different.

>>16173174
lel, the 240 made more power than that and had a respectable 0-60 time even for today

>>16172374
what kind of shit heaps are you used to owning? Volvo's and some older Saabs will go a very long time without an engine build.

>>16172986

NOt any, there are some real piles of shit out there.

>Volvo's and some older Saabs will go a very long time without an engine build.

Because they're 2.5 liters putting out 120hp and cast iron. That's not saying much.

>>16173834
The Volvo 2.3 turbo made 160hp, which was about the same as a 5+ liter v8 of the time. Saabs 2.0 turbo was making 185hp.

>>16172299
Nice. I love an engine bay that flaunts the supercharger.

There is no replacement for displacement, you retard. The higher the initial displacement of an engine, the bigger it's potential in the long run. Stroking is always an option and running boost on a massive displacement engine only gets you bigger gains.

Why do you fucking import faggots argue that fact?
