I know this issue has been touched upon many times, but why is it that we have not gotten any closer to getting one to our market?

In the May issue of SCC on page 169, there is a picture of an S2000 with a roots-type blower from the Tokyo Auto Salon. The kit is apparently made by Ogura.

Does anyone know anything more about this kit? How we can get one, will it work? If it won't, how do we make it work? And of course if we can't make one that is already made for the S work......how do we go about making one for a LHD????

 

 

That's the one!! Man, that looks nice. I want one

 

What will be the advangtage/disadvantage of having a roots-type?

 

Check out these manufacturers for roots-type superchargers:

B&M - BDS - Eaton - Holley - Littlefield - Mooneyham - Weiand

Also look at Whipple for a screw type supercharger ( I know they make one for the NSX)

Here's a bit of a comparison chart:

Roots type blowers provide a set volume of air per revolution. So the amount of pressure throughout the range is pretty constant. The up side is that you have boost (and hence torque/power) down low rather than just the big boost up top like the centrifugals.

The downside for us S2000 owners is that you will need real engine management. An AEM ECU would be my suggestion. The SC kits (such as the one I bought from some dodgey guy on a bulletin board ) don't have much if any effect down low, and just rely on increased fuel pressure up high. Much simpler application.

That looks awesome. The advantages are full boost from low RPM all the way to redline vs the gradual build of a centrifugal with peak boost at redline. IMO, centrifugals are for muscle cars. Cars with a lot of low end torque but not a lot of pull up top. Not for an S2000, which is basically the exact opposite. A roots blower would be a great match for this car. I'm not quite sure what kind of blower that is. It doesn't look like a Magnussen, but I could be wrong. This looks more like the Kenne Bell type they put on the Ford Lightning's, which the TB on top of it, or in this case, on the side with the way the SC is mounted. I bet that car hauls.

Looks like fittment for LHD car's might be very very tight or impossible without mving things around.
