The supercharger has to work harder to push the air through the manifold though, and as the supercharger is driven by the engine, this will reduce power output.

This said, i seriously doubt the manifold is a significant hindrance to power.

Agreed it would probably not make much difference, but I disagree about needing turbulence
The less restriction & the higher the flow, the lower the back pressure (boost) required to achieve a given power.
Therefore a high flow head / inlet will not need as much boost & will have the benefit of a lower intake air temp.

If there is not enough turbulence going through a supercharger rotor to mix the fuel,
I don't see that a square edge on a plenum will help

Too many cars, and too little time.

So far, EVERY technical book and article I have read has mentioned HAVING square edges and/or tight turns to induce turbulence into the airflow. This is meant to re-atomise the fuel that can build up on the walls of the manifold.

Makes perfect sense to me.

I have not looked lately but I don't see that in the V8 one's

Once again.... it wont say to do that in EFI setups....

I think that you guys will find that for peak performance that every motor requires different setups. There is no one design that suits all motors, especially if you are reading about v8's or injected motor's as they are completly different to mini motors.

Not that I think it really matters with that setup, to me it is a nice cheap way to extract decent power out of an a series. If you really wanted ultimate power you would do an engine conversion, things like the 4afte are probably putting out more power factory than you could ever hope to get reliably out of an a series.

If you really wanted to set it up a bit better you could always do a port job on the inlet side of the head and leave it intentionally rough to re atomise the fuel and design a better flowing manifold. It might work and it might not, but you will only get the perfect setup through trial and error (and $$$$$$). Remember these 4agze superchargers are not the best design either.
Just my 2 cents worth.

I thought suck-through Supercharged setups were good because the Blower atomises the fuel very well?

What's your choice's

Click on `supercharger kit'...

Personally I would go with a turbo for outright power as I think that they make more hp, just at higher revs. It would be efi with a decent aftermarket computer too, intercooler, custom manifolds etc. Thats only if I wanted the ultimate a series.

But I couldnt be bothered with all of that. I think that $$ per hp I would either use the cheap supercharger kit on a mild 1275 or just do a conversion. Probably the supercharger due to the fact that there is a hell of a lot less work involved, its a hell of a lot cheaper and I dont think it would be too hard to get approval.

But thats just my opinion.
