Hey, I ran across this on the G-Power website.
passing it along, hopefully something new.

anyone else curious as to why they used the stock i manifold?

[Z4-VILLA]

it might be to keep the cost down

This for the M54?

They had a kit out for a while that was extremely expensive, but I never heard much about it other than in UK tuner magazine reviews. I want to say it was one of the first on the market. It used an ASA centrifugal blower. Unless it is significantly cheaper than ESS's TS options, I'd go with ESS for the low rpm torque.

Might as well go turbo if you're considering a centrifgual supercharger. It's still got lag, but it's also got the parasitic losses of a supercharger. It really doesn't make much sense. Positive displacement superchargers provide instant boost all over the RPM band. Centrifugal superchargers don't. They're like a turbo with the power limitations of a supercharger.

I like ESS's twin screw set up much more (though I'm probably a bit biased, haha). The base kit gets you to 280 at the wheels.

^agreed. i tried to look up the post about the turbo e90, cant find the point where he switched from turbo to supercharger.... no idea why you wouldnt use a turbo?

Ease of install, cheaper, easier to manufacture a kit because there are less parts and less plumbing, and fewer custom parts. Centrifugal superchargers have better throttle response than turbos. Turbos also run hotter.
