Question Turbocharging vs Supercharging

Hi everyone,

As part of my education, i'd like to know the pros and cons of turbocharing vs supercharging. the people i work for are certainly split of the issue....some love turbos and others would pick supercharging over turbos anyday. i know a little about points in comparing them but was wondering if anyone here could help me out by listing a few pros and cons of each.

thanks.

Personally, I'd prefer the turbo option. I think it leaves a lot more scope for development, and I think it has alot more performance
potential. It's probably more suited to performance applications than supercharging. Then again I am honestly not too familiar with supercharging, may need to ask laminge or botch about that one as they have proven supecharging can be just as potent.

i'm more of a supercharger person to be honest! there's no turbo lag - the performance is there from the word go! BUT, the performance potential of turbo vehicles is huge!

Have a look at this link from the site www.turbodrivenconcepts.com these guys make 1200+Hp Twin Turbo kits for 5L Mustangs(and of course less powerful kits)
It details why turbos are better than Blowers(although of course it will be slightly biased but its an interesting read anyway)

Personally I prefer supercharges so much nicer to deal with as a day to day proposition lag sucks & you don't have to thrash your car to make it go alright like a turbo .
There is several diferent types of supercharger such as roots,centrifugical screw etc each gives quite diferent results it depends what your after & space etc & don't beleive people that there isn't the potential in supercharges that there is in turbos look at drag cars like topfuelers doorslamers etc.

Well, if you are talking 5.0L V8 you are talking 400 +Nm of torque on tap anyhow. It's not a 2.0 ltr 4 we are talking about here.

I wouldn't think you would notice the lag - this is all speculation though .

Turbo's usually cost more to fit,not the same control on boost. Because it's exhaust driven, the energy to drive them is almost free,I have read %10 more back pressure on exhaust..
They make humangous amounts of power.The twin turbo have been banned in the states in one class of drag racing for it was better than every thing els,class were two multifying factors are allowed.
Blowers.. there are quite a few different types. The one's on most
5Ltrs these days are centrifical,much like a big turbo without exhaust housing.Driven off front crank.Centrifical usually make more power from 2k/rpm up,like turbo the more you rev= boost..
Easy to fit in a day.Can easy be taken off and onto another car.

The down side is they take more power to drive them,on a 5 ltr so what!! We only want performance not a top fueler!!
Then there are the blowers like Kenny Bell make that are possitve displacement[look similar to roots type].Power from very low down in the rev range
seen alot on the U.S o.h.c. Fords [Hopefully here soon pluss K.B]
Trouble with these is bonnet clairence..These are similar to what is on the Lightning [f 150?] truck they are faster than some sports cars at over 2 ton, thats some GRUNT!!!!

there was supposidly a negative supercharged chrysler donk on some website. I couldnt find the info anymore but are any of you aware quite what negative supercharging consists of?
I love Superchargers but i feel turbocharing will be around longer.
Just look at cars like the corvette callaway sledgehamer whcih does 410km/h. Also the dodge viper henessey 800TT whcih does 0-100km (on DOT racing tyres) in 2.4 seconds. top whack is 240mph, bet then again it's oly running stock boost of 7-8psi. Imagine the speed and power if you whack it up to 1.3BAR!!!
