Which is more effective Turbocharger or Supercharger ? - Team-BHP

Shan2nu · 4th March 2004, 15:05

I'd like to know which is more effective.

Superchargers are more efficient but as it acts as a load on the engine output , it take some power of the engine.You can say it is like a air compressor connected/taking drive from engine.You know why with AC cars give a lesser mileage , bcoz the AC compressor loads the engine and it inturns consumes more (little more)fuel.
But on the cont , the turbo is taking its drive power from the exhaust , so it is not loading the engine .So there is no power loss from the engine as it is not a load in the engine .
But as you all know Turbo doesnt perform well in less RPM , it comes to action after a particuular RPM(based on each engine chareteristics)..But in Supercharger you dont have that problem as it is a direct drive from engine and it works in all RPM.
So eventhough you cannot comapre both the system drectly as each have its won advantage and diasadvantage , i feel the Turbo is better than SC as it doesnt act as a load or takle a drive from engine .
And over all performance of a Turbo is better than SC.
So SC taken seperately compared with TC is better , but when you fit it on a engine and then compare , TC is effecient than SC.
And ya we have multi stage TC to handle this problem in Low rpm s too !

I don't think a TC should have any problems in a race car where the revvs hardly fall. I wouldn't want a SC to load my engine, i'd like all the power to go to the wheels.

Also isnt there a turbo lag, whch is not desirable while racing??

I guess that problem is only with big heavy TCs. So instead of having 1 huge TC you can have 2 small ones. That way the TC will reach optimum revvs quicker.

Aha, one of my favorite discussions. I'll list the important similarities and dissimilarities in point format to make it easy for you to follow:

1. The turbo charger and the super charger are both forced induction systems i.e. forcing more air into the engine. More oxygen = More power.
2. A supercharger is belt-driven, while a turbo charger is exhaust driven.
3. Due to point no. 2, the supercharger will "wake" up almost as instantenously as the engine, while the turbo would need sufficient pressure from the exhaust gases to get it spinning. Thats why the term "turbo lag";.
4. Turbos have more of a potential to deliver greater power than superchargers. In fact, most installations of the same budget and scale will yield significantly more power from turbos than from superchargers.
5. Since turbos are free power (exhaust driven) and superchargers generate their power from the engine, fuel mileage is better with the turbo.
7. Turbo's are generally quieter than superchargers.
5. T-chargers have a load of potential for tuning, not so the case with superchargers.

Hope that helps,

If it is for Racing then Turbo is better.
And all the other adv and dadv have been clearly stated in the message board.

Hey guys,

I have stayed away from this topic till now because the question of which one is better really depends on a lot of factors! What purpose the car is going to be used for, what you are looking for, which model of TC/SC etc etc etc!

Rehaan thanx for the information the site is really informative

Shan2nu · 8th March 2004, 14:59

The TC would be the perfect weapon for racing, keep the revvs up and you'll fly.

both turbos and superchargers stand their own, it's really upto you. the fact that supercargers do rob power at peak revs/boost. but then again the supercharger whine IMO is to die for. as anybody who's driven a Kompressor engine would know.

Shan2nu · 16th March 2004, 20:09

Hey guys check out this months Auto India. they've printed a whole article on TC vs SC. Wonder where they got that idea from

You tend to be a turbo freak after you drive the Octavia RS,any CRDi or CDi powered car (the technology's basically the same) till you drive a Kompressor.Any Kompressor,C,E,SL,SLK,S and you're hooked.Supercharge my cars anyday!!Too bad only MB has managed to perfect the system.
