Blower pulls power from the crank regardless. If you want max power at 10psi.....still go turbo. The only thing a blower has to offer over a turbo is throttle response.....

 

you guys are missing the point here. the original question is will the turbo flow more air which equals more hp even thou its making the same boost, and pretty much from what ive been reading is it will.

 

I am going to try my best to make this make sense. Yes, a turbo will flow more air at any psi than a D1. Why? The reason is simple, the main advantage of a turbo is that the turbo's speed is independent of the engine's speed. This means your turbo can spool to your boost level and STAY there. A supercharger cant do that because the boost is a linear function of engine RPM, because the supercharger's speed is fixed to the crankshaft's. This means that at every RPM other than redline, the turbo'd motor has more boost than the supercharged engine. The turbo'd engine will be producing more torque and flowing MORE AIR from spool all the way to redline. At redline, both engines could theoretically be flowing the same but one rpm is very insignificant overall. Make sense?

 

Additionally, a larger turbo will flow more air than a smaller turbo at the same pressure level, because the exhaust housing on a larger turbo is less restrictive. On a turbocharged engine, lowering exhaust pressure has a similar effect to raising intake boost pressure.

 

but.... say we still run with the D1 for this example, what if you pulley down like crazy and run a wastegate to control boost? Then you can have your boost everywhere. or do the same with an F1. d1 @ 10 lbs=600hp ( hypothetical hp ) . Overdriven F1@ 10 lbs on wastegate makes over 600 hp?? yay or nay?

 

No. Your still making 10 psi. But with a overdriven f1 with a boost limiting valve at 10 psi will reach 10psi a lot sooner than a d1 without. So the result would be a big torque increase. But then the argument about overworking the supercharger and creating more heat.

 

This works vary well, if the sc is spinning full blast but makes 0psi it dont take much power at all to just spin it free, on a sc it only eats power from the crank according to the amount of boost it makes not how fast it spins.

 

at that point your just making more power to waste more power. Superchargers suck up a LOT of power to turn

 

But you still gaining a lot of power. And since your blessing off some of the boost there is less pressure against the turbine so it doesn't "use" as much power

 

Yes you are still using the power. Just because you vent it to atmosphere after you compress it doesn't make it free power. Just think about that. You are basically suggesting over driving supercharger and then wasting all of the work that it did bby bleeding off most of the boost. Do you not see what's wrong with this?
