What is the best, Turbo or Blower??
 

Well, both increase power too much. What´s the best and why, in your opinion.

I guess for the V8 engines the blower is better. So much power with no "lag". But for 6 or 4 cylinder engines, i guess turbo. With wastgate off course, and a big intercooler to "freeze" the air, increasing power.

I am going to have to say turbo for High HP applications

Why?
More Efficent
less Heat
Sounds cool

For autoX I would go with a Blower!

Yeah, i like turbos too... so much more in a Nissan Skyline GTR R34..oh my god.

:D

It really depends of what your going to be using it for and where you want your power. For a smaller engine car, a you will probably get more use from a turbo. For big cube engines a blower will be more efficient. With a blower you will have more power in the upper RPMs and a turbo will give you better power down low since it is driven through the exhaust pressure and not through the crank as a blower is. A turbo will spool up exponentially with exhaust pressure, while a blower spools linearly being tied straight to the pulley system. Personally I'm partial to the blower just cuz I have one and I think they're much easier to work on.

A turbo will always be more 'efficient' than a blower as its run off the exhaust gasses, which would otherwise be wasted, whereas the blower is run off of what would otherwise be 'useable' power directly from the crank.
I personally prefer turbos.

I find the modern use of turbos to be "funny" as they were originally designed to help fuel economy.

Personally, I'd have a blower and turbos. Have the blower for the lower rev range, and when the revs hit the limit where the turbos have spooled up, have the Supercharger disconnect via an electromagnetic clutch plate.

What is the spec of your car? Got any pictures?

Right now I've got a D-1SC twin intercooler system on it. Running about 520 RWHP and 480 RWTQ. My avatar pic is my engine bay. I've got the car out right now getting a custom hood fitted and painted. When I get it back sometime next week I'll have some new pics.

For drag racing you want a Supercharger since there is no lag unless you invest thousands and thousands of dollars in a really hightech turbo system. If you use a centrifugal supercharger you can intercool it and defeat the heat problem. The idea of using both types of forced induction is workable but electromagnetic clutch plates switching them on and off is rediculess using them both is the best idea you can use a Centrifugal supercharger forcing air into the turbo forcing the turbo to spool up that way and then sending it through an Intercooler since the heat created would be obsurdly high and the amount of room required to plumb all of it would be high and the engine would have to be bullet proof to be able to handle the amount of PSI going into it. The arguements for both are good but using them together just isn't efficient in any way. I use both in different cars of course and they are both usefull.

There isn't really a straight answer to the question - it depends on too many variables and so its really down to the individual application and what you want from the car. Personally I love the whine of a supercharger when it gets going but then but then the sudden rush of boost from a turbo is a great feeling.

A lot depends on space available in the engine bay. And a blower is most of the time heavier than a turbo.

There doesn't have to be lag with a blower, just adjust the transmission and you get high blower rpm at low engine rpm.

The point about the electromagnectic clutch plates is due to the supercharger having to be disengaged after the turbo comes on boost, due to the blower restricting the engine after a certain rpm, compared to what the turbo can supply. Ur method would aid spool up, but once the turbo is on full boost its pointless cus the charger is still the limiting factor. Hence why it would need to have some form of clutch to disengage it.

Superchargers aren't connected the transmission so changing the tranny setup wont affect the Supercharger. there isn't any lag either since the supercharger spins even at idle so that when you lay on the throttle the power is instant

^^ i think he means the transmission system (or pully system) for the blower itself.

You mean the surpintine system
