im still going to disagree with you for the sheer fact that you are having a draw on the engine to produce power. a portion of the increased power from the blower is being forced to power itself. turbos utilize existing exhaust flow and thermal expansion but require no additional load to power itself. sure you can compare x to a ## whatever.Originally Posted by RWD164
Fair Point, but small bore motors (Under 2.5L) tend to be a bit laggy with any real boost/big turbo. Sure a small turbo on a small motor is Ok, but a small supercharger will give power from nearly idle to the redline, where turbos need to spool and the less exhaust (small bore) the longer the spool time, the more lag. I am simply wondering why people do not supercharge more, I am not here to nit pick the finite details of forced induction. You want that arguement, create an new thread...
The power that is "drained" from a supercharger is negligible. It is the same as running the air conditioning. When tuning a car it is important to run the car at maximum load to accomplish the optimal fuel maps. Therefor if your running a supercharger then it is getting the most smooth fuel map, which makes for bigger gains.
Wow i don't even know where to start with this statement. First off, a supercharger is WAY more parasitic than an a/c compressor. The amount of power needed to compress enough air to feed an engine is quite a bit more than the small amount of freon that is compressed. When tuning a car you want to tune a variety of conditions, part throttle and WOT both. Supercharging makes very little difference tuning wide and you certainly don't gain any power over turbo through the tuning methods for a s/c.
But either way when tuning a car, SC or turbo, you place the car under max. load to ensure proper fuel mapping. I also know about WOT and partial throttle parameters which don't play as big of a role as: going up hill, AC on, etc...
EH having a/c on and going up hill doesn't really make any difference tuning wise.
