Turbo vs supercharger

Well, in general, turbos create more power for the same price as a supercharger, but getting into mustangs is a different story. A turbo set-up, which I would prefer going with a TT instead of a single turbo, requires a whole bunch of space, so it takes more manpower and parts to install, which is generally going to cost more. My turbo set-up that I am looking at is going to cost over 7000 installed probably, you can easily get a supercharger installed for less than 5k. I'm just a turbo person, I like the fact that you don't always have to be running your turbo, so you can save at least a little bit of gas.

Centrifugal superchargers dont use up any more gas unless your under boost.. on my procharger setup i dont make boost till 3K so i can drive around town and have no problem with gas mileage. Also, a supercharger is more efficient than a turbo (esp. twin turbo).. plus you wont have the turbo lag(not so much would occur on a twin setup because they spool faster). and you can get a blower for around 3K and then figure another $1200-$1500 for tuning, and necessary fuel and air meter upgrades. just my $.02

I would have to agree with procharger on everything. The superchargers are more effecient and there are always ways to get around killing your gas mileage. Basically, what he said

*Cough* Do a search *Cough*

A decent JY/DIY setup could be fabbed up for ~$1,000 if you do it right. Then the extra cash for the necessary upgrades and tuning on top of that. I am still tossing up the idea of a turbo setup once I get the shortblock to support it. But for now, my Vortech treats me just fine. And if I decide to stick with the blower even after I get the built bottom end in, I can just turn up the wick on the Vortech to bump the power.

LoL you dont build boost till 3k....something is wrong my friend. Also this could be the first time ive heard a super charger is more effienct than a turbo. Lets break this down:

====================================================
Supercharger =

belt driven - crank energy required to make spin turbine / create boost

Always on - if the motor is spining, its spending power spining it.

Rpm limited - limited by the rpm of the motor.

TurboCharger =

powerd by *SPENT* exhuast energy

only on when engine is under 1/2/full throttle, basicly out of the picture until needed.

not limited to RPM, Normally spins at 150,000 rpm boost ranges by turbo 5psi -20psi EFFIENCTLY with a junk yard T3 pull....30-40psi with a hybrid or T4 +.

Properly sized turbo's have little to no lag time...even with a decent sized turbo the lag time is usualy not even noticable.
================================================

Pound for Pound a turbo Always makes more hp than a supercharger...why? becuase its more effiencent. Now that we have some Facts in here, we can all smile and feel smarter

actually turbos are more efficient, u will be making more power at the same psi with a turbo. if u have friends that are into that kinad of thing, then u can have a turbo installed by them for pretty cheap. with a shop the price goes way up though. supercharger is generally easier to do, and their are already nice kits out there.

funny, most turbos don't hit fullboost till 3000 RPM, gotta hate that lag!

You guys got any sort of evidence supporting that? Even these supercharger guyys say that:

Efficiency
This is the turbo's biggest advantage. The turbocharger is generally more economical to operate as it as it is driven primarily by potential energy in the exhaust gasses that would otherwise be lost out the exhaust, whereas a supercharger draws power from the crank, which can be used to turn the wheels. The turbocharger's impeller is also powered only under boost conditions, so there is less parasitic drag while the impeller is not spinning. The turbocharger, however, is not free of inefficiency as it does create additional exhaust backpressure and exhaust flow interruption.

linky This sight has some good info, but most of their turbo drawbacks are easily delt with.

The extra heat usualy goes through a Front mount intercooler.

If it's normal to not get boost until 3000 RPM supercharged, then the lag argument is just wrong. But, I think that's not normal. The "surge" if properly fueled will cause no damage to the engine.

The backpressure argument, Once the turbine is spinning it won't cause any extra backpressure, maybe an insignifigant amount. Hell big diesels use huge turbos for exhaust scavenging pumps.

Reliability..... old ill cared for bearings can be a PITA but it's just a matter of caring for your car. There are systems like turbo timers that idle the engine down and keep the oil circulating while the turbo cools. Also one has to be educated as to the difference between cast manifolds and tubular aftermarket headers that turbos can fit on.

Remember that there is a difference between centifugal superchargers and roots type positive displacement chargers. Plus, TURBO is such a cool word to add to your car.
