No it would increase your mpg on a low boost setting. Turbos run off the unused exhaust fumes, thus making your engine run more efficient.

Nope, turbos and superchargers actually help mpg a good bit if you drive conservatively. But most ppl want to feel the power of their forced induction so more air flow=more fuel.

Superchargers don't increase mpg. They are belt driven.... Which cause more work for you engine.

Both will increase mpg if driven properly. The increase in power is greater than the loss making the motor more efficient.

This off of another thread.......

----------------------------------
* - unavailable
- The lowest/highest psi advertised/known HP gains. The highest HP gains are with built engines, etc (no N2O).
- Upgradable means if the F/I unit can be upgraded with larger intakes, intercooler, etc.
- Most common advertised price; many sites offer better prices.
- The horsepower/dollar ratio is calculated based on max advertised HP gain. The formula is “total cost ÷ HP gain”.
- Most units have a higher max HP capability than listed. The highest HP gains known are listed.




TOP PERFORMERS:
Horsepower per psi: Kenne Bell base 2.6L - 34.2 HP/psi; Turbonetics Single Turbo - 29.41 HP/psi
Max HP capability: Kenne Bell 2.8H Mammoth – 775 HP; Impulse Engineering – 1200 HP
Best value ($/HP): Kenne Bell 2.8H Mammoth ($13.26/HP); HP Performance – STAGE 3 Single Turbo ($8.91/HP)


PROS + CONS
Component - Supercharger -- Turbocharger

Cost - Generally high -- Some cases low; some cases very high
Lag - Little to no lag; produces boost at very low RPM -- Exhaust must spool up before boost; on today’s 4.6 V8, spools very quickly
Efficiency - Runs off power from the crank; robs power from the engine; can sometimes increase mpg -- Reuses “wasted” exhaust gasses; less parasitic drag when impeller isn’t spinning & can increase mpg
Heat Intercooler required on some applications; still gets hot Intercooler required almost definitely; runs very hot (rear-mounted turbos have less under hood heat)
Surge - Generally continuous power -- Once turbo spools up, huge surge of power
Backpressure - Not much more than stock -- Exhaustflow is interrupted by turbine
Noise - Generally much noisier than stock all the time (whine) -- Not much louder than stock depending on application (located in exhaust); only noisy when boost kicks in
Reliability - Doesn't require warm-up/cool-down time; can throw belts and cause damage to other engine components -- Requires warm-up/cool-down time; very high RPMs; residual oil; higher heat; fewer mechanical and moving parts
Ease of Installation - Usually very simple; few pieces; somewhat difficult to do regular engine maintenance -- Generally complex; many components
Maximum power output - Limited; depends on size -- Can reach very high RPMs; outrageous peak boost numbers; huge peak power
Tune-ability - Generally easy to tune because of simplicity of design; needs different pulleys for different boost levels -- Many components which require extensive and generally difficult tuning; easily change the boost level
Gas Mileage - Generally decrease mpg because they run off the engine (parasitic loss) -- Can increase gas mileage because they make the engine more efficient and don’t take power from the engine

-------------------------------
Summary

All in all, turbochargers are pretty much a better buy for the money if you plan on going BIG. Nearly all turbochargers have the capability of reaching unbelievable amounts of horsepower (not to mention torque!) that most superchargers are not capable of (there are a few exceptions).
Not everyone needs a turbocharged monster and for many a supercharged or "lower-level" turbocharged Stang will offer more than enough power to keep them happy and smoke some ricers while at it!
This is a very opinionated topic... However, both superchargers and turbochargers are guaranteed to make a stock S197 4.6L V8 Mustang GT kick some serious ***!

Thanks for reading! Hopefully this has been of some help for you!

Why don't very many people seem to use the Edelbrock SC, it seems like a very complete kit and straightforward to install?

Glad to see that post on the super charger, have you ever seen any other data or research on it?

I drove my 2005 Mustang GT with twin turbos down to Knotts Berry Farm for the Fabulous Fords Forever Show last week. My average for the 280 mile round trip was 23.6 MPG. That includes climbing up and over the Grapevine (4400' altitude), and bumper to bumper LA traffic.

Really? That's insane, but would you recommend turbocharging a daily driver?

I would not want to drive mine every day.... the RAM clutch is really heavy, and it is tuned right to the edge. Makes it a fun weekend toy. If your setup is kept pretty mild, there is no reason you could not make a daily driver of it.

Edelbrock's website shows 6 different pulleys for their supercharger line.
