The fact remains that a supercharger will always be inferior do to the fact that it's speed is fixed to the cranks speed. The turbo will have a more consistent level of boost and will therefore flow more air through the rpm band.

 

Yes. But by overdriving it you will see max boost a lot sooner. Maybe even as low as 3k rpm depending on the setup

 

I did alot of research on this when I was thinking of going procharger, I know it seems like it would just be working against everything but it does work, most people see more peak power because it brings the power curve down a bit cause it makes more boost everywere below the peak rpm. Look into it works

 

East Coast Supercharging did this years ago on Vettes with their Novi 2000 kits. It worked. As I recall it boosted way better down low.

 

I think there are pluses and minuses to the blowoff with a Centri blower. I don't think anyone is trying to get TVS type low end by doing this. As 2plus2 said the blower is directly tied to the crank, and sometimes people with centri blowers see a spike in boost at redline... if you just bleed off a few pounds at or near redline its not going to be eating that much power and I would say it could work well.

I'd say we're a a little off topic here haha.

Also, if something like a TVS creates a certain amount of air with every revolution, I dont see how it matters that the turbo will be spinning faster... you will just bleed off all the 'extra boost' at the lower RPM's if the goal is to compare apples to apples, 21# to 21#.

I'd be curious to see how much more air a SC moves than the turbo due to the free flowing exhaust and difference in cam specs.
