<div class='quotetop'>QUOTE(00GTZ00)</div><div class='quotemain'>That drag though stays at ~1% of the total output of the SC power. So if the SC is making 100 hp it will take 10hp to run the pully, 200 hp it will take 20 hp etc etc. not a bad offset in my book...what % of hp does the turbo rob from the engine? it is in the way of the exaust flow yaknow..and creating all that extra stress on the exaust manifold and head or heads..</div>
yes, it is in the way of exhaust flow, however, the turbo can basically "spool itself." That is, the excess air being forced into the cylinders spins the turbo much faster than it would without the excess exhaust gases. It's like a fake hp loss, if you know what i mean. It may be a loss, but it is overcome by the added air forced through the cylinders. With a supercharger, no matter how fast you spin the turbine, the supercharger will not stop sucking away power, in fact, it will suck away more.
