What about a screw type supercharger for the Max?
I was thinking lately how a screw type supercharger may work on a Maxima. For example, I was looking closely at the model Comptech makes for the Accord and the CL-S. Here's a pic for those who haven't seen it:

It's a little complicated with the cross shaft and stuff, but the design seems realistic for the Maxima. The question is, could a system like this yield better power? There are a lot of variables here, so think a little before posting please.
What do you guys think? Anyone think a project to throw one of these on would be worthwhile?

Stillen apparently thinks a new hood is no big deal. If you get the 350Z supercharger, you need a hood.
Good question, but the idea behind using a screw type is to get the even power delivery. In most cases uneven power delivery is not desired.

Re: What about a screw type supercharger for the Max?
Here's a good, concise description of the different types of superchargers: superchargers
Bottom line for the screw type SC is (taken directly from the superchargersonline site):
Screw Type Supercharging
Screw type superchargers are derived from the Roots type concept but with vast improvements for street use. Although from the out side, screw type superchargers may look a lot like Roots type superchargers, on the inside you will find a twin-screw design that compresses air unlike Roots type superchargers which pump the air into the motor. Screw type superchargers have an axial-flow design that compresses the air as it moves between the screws to create positive pressure without creating the heat that Roots type superchargers can create. The Screw type supercharger's ability to produce a dramatic increase of power from idle and through out the rest of the power curve make them a great choice for heavy vehicles, towing or commercial use.
Recommended Usage:
Street Use - Towing - Road Racing - Drag Racing
Positive Points:
1) Great Power at Low RPMs (Great for Towing)
2) Lower Discharge Temperatures (as compared to Roots)
3) Factory Fit & Appearance
4) Great Reliability
Negative Points:
1) The Power Doesn't Keep Climbing in the High RPMs (Power curve is very flat)
2) Challenging To Achieve High Boost Levels or CFMs
3) Lengthy installation times
Manufacturer Availability:
Kenne Belle - Magna Charger - Whipple

That was a great site. After reading that it doesn't sound like something you would want to hook up to an Acura 3.2 engine. Possibly Comptech is just trying to gain a little bottom end and letting vtec do the work up top. A similar style supercharger seems to work well for the Grand Prix guys though. With a smaller pulley they are seeing some pretty powerful 3.8's I'm not positive, but I thought they were using roots type blowers made by Eaton. I'm also unsure of what the websites definition of high RPM is. Over 4-5k?

So can you guys define high rpm? Does that start around the 4000rpm range, or higher? If it builds to around or above 5 grand you gotta think the area under the curve might be greater than a centrifugal application. Area from shift to shift...? What about torque. Seems like the application might give you more torque than the vortech we (well, you guys) run. I would also think achieving 8 psi should be easy enough. Anyone know where I could get a look at various types of superchargers flow rates graphed over a rotational speed range?

Jackson Racing uses only Roots-type blowers and they offer kits for all kinds of high revving Hondas. Roots blowers are IDEAL for street driven car, IMO. They give you strong lowend torque and a much more useable powerband. The Grand Prix GTP, 2003 Cobra, Benz (varient of the Roots), TRD for Toyotas, etc use these blowers with excellent results. Some of these cars make good topend power too. Roots blowers are also extremely reliable.
If a Roots blower was available for the Maxima, I would be the first in line. I wish Nismo would have copied TRDs roots blower design for the Camry/Solara.

A VQ with a roots-type blower would have AWESOME midrange.
