Turbos vs naturally aspirated?

Regulations schmegulation, Ferrari should just supercharge everything, and hire VW engineers to program their ECUs. Problem solved... Well at least for a few years.

Excellent video Thomas ^^^ Driven as it should be, I absolutely love it.

 

Pretty much says it all.

 

Boxerman, I agree with you but isn't the added weight of the new model in part due to more and more tech goodies that are fitted to the car? (Nav, Sat radio etc)... I agree that going with any forced induction means you might get away with a smaller combustion motor, but you now have to add other components which add weight.

With the F40, it could be powered by a Flux Capacitor and we'd all say- oh wow! Its an F40. I don't think the F40 was much about the sound, it was simply about Enzo's last direct connection, the epic shape, and being the first street production car to crack 200MPH. Remember most of the tech in the F40 is from the 1980s- and I bet some of it isn't much different from the 1970s! The defining thing about driving the F40 is when the boost comes on. If they made the 488 drive the way the F40 drives, it would lose every comparison test in a hail of complaining about the lumpy power and no power at lower RPMs.

 

I think what makes the F40 is its near total rawness, coupled with extremely light weight, that rawness works with the raw turbo motor.
That off boost and then a big bang is all part of the character of the car, its a product of its time, and was unualy raw even for then, nothing like it since. Even the stick is part of the package, no ps etc.

We have also come to exp[ect NA motors as in the 458 making way more than a f40,

In fact one must ask what are we realisticaly gaining speed wise with the 488 and what are we looing vs a 458, and is it worth it.

 

NA, SC or Turbo?
Each has their own specific pros and cons, and I can be seduced by them all.
I love the growing intensity and high pitched wail of a well tuned, high revving NA engine.
I love the instant thrust and mountain of torque of a SC engine.
And I love the ultimate power a Turbo provides.

I used to say I preferred NA over Turbo, but I think nothing makes the distinction clearer than a Porsche GT3 vs a GT2. Make mine a Turbo.

 

I had both when I owned three MKI MR2's along with a MKII Turbo. I prefer turbo over n/a for ultimate performance.

 

That's certainly true for small displacement 4-cylinder engines, but I'm not sure that's entirely relevant in a discussion mainly about comparing natural aspiration with forced induction in larger displacement V8 engines. In larger V8 engines, you get enough performance so that the characteristics for how the engine revs and how it sounds are more important than absolute performance, since you would have more power than you could sanely fully utilise on the road anyway even without forced induction.

All the best,
Andrew.

 

Does anybody know why Lambos tend to catch fire more often than Ferraris?

 

I sense a punchline?

 

Well, I'm sure it feels like a punch when your car catches fire.

All the best,
Andrew.

 

Right, to me the F40 is a product of its time. I am excited about the 488 as its a Ferrari but I would be more excited if it were NA.

 

Those are called 458's and were at the limit of what a n/a engine could do with the restrictions of being a LEGAL road going vehicle. Just my opinion of course.

 

I'd rather see Ferrari go back and detune the F1 V10 engine that carried Schummy to so many victories.

Lambo / Audi are using a fantastic NA V10 engine, and both the A8 and Huracan have spectacular performance that can easily hold their own against either the 650S or 488.

 

Hard not to agree with you on this idea, kudos.

 

If it's not a V12 it isn't a real Ferrari.

I think the V10 is another non starter that would be argued about.

 

I understand and appreciate the importance of a V12 - I own one myself.

On the other hand, how does the thought of having one of the most successful Ferrari F1 engines in YOUR personal Ferrari sound?

 

I never loved a v10 untill I drove a a carerra Gt. I hear the lexus one is great, and BMW did one too, also great.

 

What are electric turbos?

 

Electric turbochargers do not require spent exhaust to drive the turbine wheel thus using a electrical 'driven' energy source so there is basically instant spool-up. They have been around for years but the concept is just now starting to gain more acceptance. I think the initial cost, which I do not know, could have been a factor.

 

There's no such thing as a turbocharger with no turbine driven by the expanding hot flowing exhaust. If there's no turbine to drive the compressor wheel, it's not a turbocharger. What you describe is an electrical driven compressor, commonly known as a supercharger or blower.

If you don't have a turbine to drive the compressor, you'll A. Need the crank to drive a generator/alternator as to provide power to the electrical system for the compressor, or B. Do as have been done for years i.e, drive the compressor directly from the engine, one way or another. Both takes power away from the engine, and the latter a lot more than a turbocharger.

 

the way I now understand it, is the battery drives the compressor instead of the exhaust gas or engine pulley. makes sense in that don't use engine power like supercharger does. not sure what the advantage is over exhaust driven turbo though. extra weight of batteries seems like downside

 

correct... driven by something other than exhaust it becomes just another compressor... in this case an electric motor in place of a turbine in the exhaust stream...the "turbo" refers to the turbine as a source of power / drive for the compressor...

anything electric gets its' power from a generator, a battery is nothing but a storage device which needs to be topped up by a generator.... generators usually get their power
from the engine decreasing the amount of power going to the wheels, decreasing available performance... having renewable electric energy reduces the size of battery and saving weight...

some of the hybrid setups actually have exhaust turbines driving a generator instead of using mechanical power from the engine...

 

What if you have a turbo that uses electric to get it going but then uses exhaust gasses to keep it going? Then you have a combo electric super/turbo charger. The big question is... Duracell or Energizer?
