SPC Super Efficient Supercharger vs. Turbocharger vs. Belt Driven Supercharger
First off, we want you to know that we sell SPC super efficient electric superchargers, turbochargers and belt driven superchargers. Turbochargers and belt driven superchargers are special order items only. We will offer you what you want, however, the SPC superchargers offer many advantages that the others just cannot do.

Parts required other than the main unit that maybe needed** |
Extra battery, maybe upgraded alternator, intercooler, blow off valve recommended |
Turbo headers, up pipe, down pipe, wastegate, blow off valve, intercooler with plumbing, boost control |
Intercooler, intake manifold, oil cooler, bypass, blow off valve |
|
Power lag |
None, electric motors are full torque immediately |
You can pretty much expect lag, especially with large turbos |
Some have no lag but are less efficient than superchargers that have lag |
|
Power source |
|
Exhaust |
Belt |
|
Affect on engine's power |
Depends upon the capacity of the battery setup or charging system |
Always inhibits exhaust gases |
Can have huge parasitic power loss from using the engine belt system |
|
Efficiency |
Very efficiency
|
Can be very efficient |
Not very efficient |
|
General complexity to install |
In general, a lot easier than turbos or belt superchargers |
Difficult to extremely difficult |
Difficult to extremely difficult |
|
Fitment |
Can be fit anywhere you have the room and plumb it to the intake |
Very restricted, must be fit to exhaust in some form or shape |
Very restricted, must connect to engines belt system |
|
Lubrication system |
Permanently sealed lubrication system, no maintenance |
Pumped oil |
Pumped oil or oil reservoir |
|
System cooling |
Independent liquid cooling system |
Oil or oil/water |
Oil |
|
Intercooler |
Like any compressor for forced induction, it needs to be intercooled |
Must use intercooler, exhaust gas superheats the air
passing through the turbo in addition to the heat from compression |
Belt driven superchargers can have high friction temperatures or high temperatures from connection to engine. Almost all use an intercooler. |
|
Can be turned on/off |
Yes |
No |
No |
|
Can be tuned for fuel savings |
Yes |
Difficult, but can be help at idle |
Not that we know of, parasitic draw is a problem |

*this is a generalized range based on quality turbochargers or superchargers. We are not talking about junk. In most cases these prices will reflect the approximate dollar value of everything needed to do a complete installation.
** represents parts that, in general, are needed for a complete installation. Some parts may or may not be needed in some kits/applications
# If you use one battery, poor quality batteries or have a poorly functioning charging system/alternator you may not get the results you want. Like in any performance installation, only use high quality components. How you use the unit will also make a difference.
