turbo vs supercharger

[PRAVX II S]

edit.

Why wouldn't i know something on this topic?
I deal with cars every day. I have worked on both turbo and superchargers its my job to know how they work. Not to mention having to wire up
turbo timers. Boost gauges, electronic boost,
I have even fitted a turbo on my mated VL commodore.?

And yes it is proberly detuned from factory . And yes my mates turbo has been tuned.

Yeah everyone back off, he has wired a boost gauge.
Turbo is generally harder to setup and more complex due to extra components, etc.
As for the old arguement of a turbo only working up higher in the rev range, that is bullshit. You can look at different A/R's, etc to adjust when it will see boost and max boost.
A turbo is more efficient as it uses a waste product to make boost rather then crank power. A turbo setup running 10psi and a supercharged one running 10psi on the same engine, the turbo will make more power.

I said the same in my earlier post that it uses the spent gases to run the turbo in turn its more efficient.
Lol And i have done others things then wire up a boost gauge Mate.
Back in fiji when i was a apprentice i used to coil my own stator winding for the alternators for the customers. They dont even think of doing anything like that in workshop in OZ the apprentices dont even get taught that in Oz.

lol or chalk and cheese

Lol, but thats like comparing a banana and a apple.

Diff motor , car weight ,etc

having said that,SOOP IS in the know,,,he knows his stuff,,,,,,cheers SOOP

Thank you for smart post.
Although I will pick you on that last part. Its not totally correct. If you're using say, a motor bike turbo at 10PSI on an ecotec, its not going to make the same power. It will be super heated air. I realise that example is rediculous. But it goes to serve a point.

Neither method of forced induction is better then the other, except in extreme cases. I mean, just look at top fuel rails.

Also, my "comparison" of a turbo charged Ecotec and an L67, was not intended to be take as though those motors are good comparisons. But still closer then a bloody BA falcon motor.
The point was, we're comparing forced induction methods, not motors.

Turbochargers are designed for specific applications just as Superchargers are and at the end of the day, neither will be efficient if you don't do your homework.

I shall let u know what my vt v6 turbo has when I get it tuned next week

found this on the net>>>>>>>>>>TURBO vs SUPERCHARGER
Which one is best? Turbo vs supercharger? Let's take a look at what their pros and cons are:


Turbo Pros ( + )


Only one, where max boost / max power is required in full race, track application, where other considerations can be rejected, e.g. cost to build and develop, life expectancy etc.

Turbo Cons ( - )

Much higher boost pressure is needed in a turbo for the same bhp due to pressurized air being much hotter, due to conduction from red hot exhaust manifold.

Much more complex management needed in a turbo, to control fueling and ignition due instantaneous rise of boost pressure.

Higher pressures and temperatures encouraging detonation, turbo is the big engine destroyer.

More intercooling needed to cool inlet air.

Much higher under bonnet temperature making everything hotter and so reducing power.

High under bonnet temperature reducing life of things like wiring looms and hoses.

Much higher incidents of fire due to red hot turbo and manifold.

Compromise exhaust manifold and system function due to restriction of turbo not letting the gas flow freely.

Extra shock loadings on transmission because of sudden increase in power.


Supercharger Pros ( + )

Basically all the things the turbo is bad at the supercharger is good at.

Supercharger Cons ( - )

No dump valve to make a nice noise


For those building their own kit I would recommend always going to a supercharger 1 size above what the engine capacity suggests, as the price for the next size higher is quite small and if necessary put a restrictor in to reduce the boost. The reason I say this is that most people start off with quite modest expectations but as soon as they have it fitted they want MORE and if the supercharger they have already fitted is running at max capacity, they have to discard it and buy a complete new supercharger unit. This problem of running out of charger capacity is especially a problem if the engine is 1) High revving e.g. over 7000 rpm. 2) 16 valve unit, as they eat air quicker than 8 valves. 3) The compression is lowered.
THIS IS ONLY SOMTHING FROM THE NET ( SOOP would have a much better idea than myself) but i tought id throw this out there anyways...cheeers. and howdy SOOP

Clearly that was written by an unbiased member of the motoring community
Its wildly incorrect though.

 

[justbad4you]

yeah prob is (just thought id chuck it out there) not that i know a lot on this forums issue of turbo vs s/c myself

Clearly that was written by an unbiased member of the motoring community
Its wildly incorrect though.

may be i should of just shhhhhhhed up on this post lol
take it easy soop and have a good 1 .cheers

thanks for all your coments guys it has helped the turbo manafold is in turbo is on piping up intercooler when finished ill post photoes it wasnt hard to fit just need someone to tune computer .(next hassel) lol
