Are you in for Naturally Aspirated or Forced Induction?

shouldn't this be in the car section?


But naturally aspirated is better on the engine, you have forced induction and you put a lot of strain on the interior working parts of the engine.

ROFLMFAO!!111

OMFG, the responses are priceless


[FYI, forced induction(FI) = turbo/supercharger; naturally aspirated (NA) = air is naturally taken in]
Go do some reasearch on Google or something, you'll learn something...

Well, in most applications, one wants the most response out of an engine. So if you want instant response, a naturally aspirated engine will do. And if you're a "purist" car enthusiast, even better for you.

But as a rally fan, I love forced induction. Just hearing the whine of a turbo and the constant popping of the anti-lag is part of the rally experience. (But turbos often suffer from "turbo lag)
Superchargers are different though, as they have instant response like a naturally aspirated engine, yet they have the sound (almost) and the power of a turbo. But even better, superchargers do not need a totaly overhaul of the plumbing, as a simply pulley kit can change the boost. Really, superchargers are probably the best for most racing applications.....

BAHAHAHAHAHAHAH NEWB ALERT hahahah wow just reading all of this stuff NA?? FI??? Nana===WTF bahahah WOW oooo damn oh god thats to funny


but yea i like ma turbo so ill go FI anytime

Turbo cars can give you instant response too if you really look at them. Turbos dont whine..they whistle. If your turbo is whining then you have a serious problem. Superchargers whine. And to turn up the boost in a turbo car you get a boost controller and you can set it up as high as you want not like a SC where its just predetermined by the pulley size.

Iono..IMO the anti-lag sound is annoying to me. Sounds exactly like a whole bunch of misfiring. Does great for instant power but is horrible for the motor and the turbo itself. Anti-lag= worst invention ever for street applications.

^uhhh, duh, anti-lag IS misfiring, intentional misfiring to reduce lag. Please correct me if I'm wrong...

Well, I guess you're right (because only the HUGE truck/bus diesel engines have LOUD-@$$ turbos), but the sound of a loud turbo is satisfying.....

EDIT: I don't think anti-lag was designed for street use, lol.....

Anitlag is not an intentional misfire. There are different types of antilag system. An injector based system in the turbos exhaust housing and the retarding of the ignition system where the sparkplug ignites the mixture when the exhaust valves are open/opening.


Yes anti-lag was not designed for street applications but many companies incorperated a limited type antilag system that people just love to use and have no idea what it does to the motor. Once every blue moon would be fine but there are plenty of people who use it at every launch.

so... what does it really do to the motor
Posted 2/28/08
FI
turbo baby! gotta luv that boost and bov sound :D
oh and i like it bettercause it starts boosting at around 3500rpm while like vtec is like 5500ish
Posted 2/28/08
Turbos are alright but when your doing really agressive driving, it is better to have instent responce when you touch that throttle, I say Supercharge that bitch. leave the turbo lag for someone else. But i will say that turbos are better for higher speeds.

P.S. I lve the responces that people have given "N/A FI whats that"

Its not so much the motor that receives the damages but the turbo. The side effect on the motor would become the added stress levels with the continuous use of it. The bearings always take a pounding with every turbo car.

Normally Aspirated means your car air intake depends on the vacuum the engine makes, while Forced Induction is more popularly known as Turbo-charged or Super-charged, which as some of you know uses turbines or some kind of air pump to force air into the engine...
In other words NA (normally aspirated) is normal engine air intake
whilst FI (forced induction) is forced engine air intake (may it be turbo or super charged)

Now on my choice I'd chose FI (forced induction) via a supercharger for a continious boost... and fuel economy... turbos suddenly lose boost power in lower rpm's unlike superchargers which are powered by a pulley connected by a belt to the engine
which means:
higher rpm = stonger boost
low rpm = maintained boost
unlike turbos:
high rpm = boost
low rpm = no boost
turbos lose boost power during acceleration in lower rpm a terrible weakness in circuit races, thus anti-lag or misfiring systems were made to compensate for this "weakness"
(anti-lag/misfiring systems are more popular in rally cars (try listening to rally cars in the WRC) than on street cars; because they damage then later destroy the engine's exhaust system)

Personally I prefer the sound of normally aspirated cars. A nice deep bellow from a V8, or a smooth purr from a well tuned V6. Only 4 cylinder I have heard I fully like the sound of are the classic Saabs, like my 1994 Convertible. Nice deep pitch that rumbles and then goes into a growl of fury at higher RPMs
