YACT. Will a super charged engine still run even if the super charger goes out.

As you can probablly tell I know very little about cars. I am not sure how integral a super charger is to the engine. I know it does something with the air(at least I think I know) which makes the car a little faster/better acceleration. But is it require for the car to drive. I mean if it dies will the car still run and just be like a normal engine car as opposed to being super charged, or will a dead super charger prevent it from running? Thanks

Can you still run without shoes?

As long as air can pass through to the motor, I would think it would still run. If it fails in such a way as to block the intake, then no.

I think you answered that question best.
 
Assuming that the belt didn't fail and get entangled with the other drive belts, and that no debris from the S/C got into the intake, then I'd think it'd run like a normally aspirated engine. However, with boost you normally have a lower compression ratio, so you'd have a much slower engine...
 
Yes.. albeit a bit less efficient due to the S/C just sitting there. Wouldn't the engine suction turn the impeller?
 
From personal experience (the turbo once failed on an old DSM that I used to own), I can say that it will run but run like sh!t. Very little power, cutting out all the time, blowing blue oil smoke (or at least mine was). I limped it into the shop. Not a happy repair bill, but that's what I get for having a manual boost controller set too high.

btw, before I get flamed, turbo = supercharger

You're talking about a Super Charger, if somehow the suction is strong enough to turn the impeller, then it would do as much good as those "tornado" inserts that suckas bought on TV specials.

Huh.. I was inferring that if the engine is turning the impeller, induction is being restricted and efficiency will go down, possibly to the point that the engine wouldn't really even be usable.

Of course the engine will run like crap, because most likely, the ECU has been reprogrammed to meet with new fuel air ratio (with the blower). And if the air is not there, you'll have a hard time trying to burn all that fuel.

I had a '90 Talon Turbo and my turbo died after I stopped at a stop sign. I tried to take off from the stop and it was utterly gutless... But of course it still ran.

Fortunately, it was still under warranty. 🙂

Well, yeah. I always automatically think of carbureted engines though for some reason, heh.

Same concept, except now that you'll be running hella rich.

Well, probably not in most cases... Most forced induction engines have some sort of mass air flow sensor. If the air flow is drastically cut, as would be the case if the turbine stopped, then the ECU would react appropriately.

Haha. I used to have people argue that they weren't the same. Apples and oranges.

You saying the ECU will make the injectors inject a certain amount REGARDLESS of the amount of oxygen present???

That comes from 10+ years of my previous career... That being a drivability/electrical auto tech. 🙂

 
I've seen many a turbo engine run when the turbo was seized, I think that an ECU (especially today's cars) would be able to compensate for a lack of boost.

did you work on a specific brand of cars?
 
Correct.. the MAF was one of the greatest things to happen to computer controlled vehicles
