a turbo and a super make power in the same way, both force more air into the engine. they way they differ i dhte turbo is driven by exhaust pressure, and the super is driven by a pully attached to the accesory belt. when u hit the gas in a turbocharged car, u must wait for the engine to produce enough exhaust pressure to spin the turbos compressor, whereas with a supercharger the spinning of the compressor is directly related to the engines rpm. so heres the scenario, youre driving along in your civic and another civic pulls up next to u. in this scenario well say the 2 vehicles weigh exactly the same, make the exact same power, have the exact same power curves, and both drivers are perfect. the only difference is one has an exhaust driven compressor (turbo) and the other has a belt driven compressor (super). now both drivers drop gears, they both hit 2nd at the exact same time and both hit the gas at the exact same time, as they are both perfect drivers. the supercharged car will win. why, because when they both drop gears and hit the gas, the turbocharged car has lost all of its exhaust pressure do to releasing the gas during the downshift, and he must now build up the amount up exhaust pressure again that he needs to spin his compressor, while when the supercharged car dropped gear and let off the clutch, his engine rpm instantly climped with the gear change, and therefore his compressor is INSTANTLY spinning. he has his full potential power the moment he puts his foot on the gas, whilst the turbocharged car does not. now if the 2 cars had stopped next to each other at a stoplight it would be different since the turbo car can rev his motor up ahead of time to get his turbo spooling, and now the 2 cars will tie because they have equal power curves, weight, and both drivers are perfect. btw yes i have seen the dyno charts for the vortech kit, around 50 more hp and 50 more lb ft torque at the wheels at only 4000 rpm, before the vtec has even kicked in, before the exhaust has made enough pressure to sufficiently spool a turbo large enough to produce 272 whp, unless it is a very efficient turbo. and the car used in the test was not specially tuned, it had a tuned and programmed fuel control system, which is included, preprogrammed, with the kit.
