Do you need fuel injection to use a Turbo (or Super) Charger?

I would think not...but someone just told me you do....I don't see why you can't do it carburated...you'd just need to control the air intake with the throttle right?

 

[natto fire]

i know you can use a supercharger on carbuerated engines. I would imagine the same would be true for turbo since it is essentially the same.

They made Turbo Trans-Ams back in 79-80 sometime which used a 4 bbl. It can be done.

A supercharger and a turbo are two different animals.

 

[Soybomb]

You can run a carb on either. My personal preference is fuel injection for easy tuning and let the computer do spark control too, but plenty of old muscle car guys still love a finely tuned carb which is a skill I don't have

I think that he means that they're the same in the respect that they're both forms of forced induction. I'd say it's possible - but I highly doubt it'd be more practical for a turbo application.

 

[Noriaki]

I dunno...Supers and Turbos are really essentially the same.

They both force more air into the cylinder

Sure that's about the only way they are the same. They are driven differently, the Turbo needs cooling, the Turbo doesn't give you power straight off the Super does, but pulls some power off the crank.

But what I'm talking about is taking advantage of the forced air without fuel injection. In that sense they are the same.

Ed: Oops kinda worded that wrong...fixed...

<< A supercharger and a turbo are two different animals. >>



I think he meant they are virtually the same thing meaning forced air.

 

[natto fire]

thank you genocide and ASV that was exactly what I meant by &quot;essentially&quot; the same.

 

[Soybomb]

Actually as I recall, and perhaps supersix can verify, I think the late 70's to early 80's turbo buicks were carb cars

 

[Antisocial Virge]

Come to think of it, I had a article where I guy had a duel 4bbl/turbo setup with one turbo running to one 4bbl each. From what I remember the lag was so bad it would get 100 foot of the line then the boost would come up and it would fry the tires.

 

[Noriaki]

ROFLMAO!!!
HAHAHAHAHAH that's the funniest damn thing I've ever heard

 

[SuperSix]

<< Actually as I recall, and perhaps supersix can verify, I think the late 70's to early 80's turbo buicks were carb cars >>



Yes, they were. THe turbo-charged 3.1 Monte Carlos were carb'd as well. They ran relatively low boost levels as well.

You don't NEED FI, it's just a lot easier to control the air/fuel ratio with fuel injection.

 

[JohnnyKnoxville]

Injection is nice but I'd rathe be BLOWN

 

[Aenygma]

You may use either.. Trust Me

 

[Cyberian]

I know I've seen Paxton &amp; GMC Superchargers on engines way too old to have been EFI, or any kind of FI.

 

[Emulex]

you NEED proper air/fuel ratio to avoid detonation (leaning out). Its very hard to tune a carb for the slope of fuel enrichment needed.

It's also very important to pull timing out as boost grows, too.

So even if you have a TPI injectors (one or two big injectors spraying into the intake manifold) with a computer. Its just umpteen times easier to tune.

but yes, i just saw a carb'd 302 stang with a charger on it the other day. Ran horribly rich.

Rich = poor gas mileage, and loss of power
Lean = great gas mileage, more power. But too lean (14:1 air/fuel) and you'll burn a hole in your piston, burn a valve, or detonate your pistons into pieces in a second or two.

Who'd want to spend several thousand on a motor and have it blow after one bad run?

Forced air like a supercharger works more efficiently with a fuel injected system. Simply b/c it is precise, much like a fuel injector.

Putting a Supercxarger onto a carb would be a bit of a waste, given the sloppy nature of carb.s

The best way to force air into a carb is by RAM air, or air channel.
