I know I just want this post to be on top

 

What kind of fuel management will come with this kit?

 

I think it uses BR's own Elf management system. I can't wait to see how this blower will perform with a full exhaust and a CAI!!!



On a side note, I wonder why they aren't using an air to liquid intercooler vs the air to air unit.

I believe they're going to provide VTEC adjustability also.

 

Awesome. I'm definitely paying attention to this. I've always been anti-supercharger and pro-turbocharger for a number of reasons (efficiciency, power output, etc) but this has caught my eye.

What kind of boost profile are we going to be looking at? I am familiar with your typcal centrifugal supercharger profile, but i imagine this PD unit will be a bit more flat?

 

We decided to use the air/air IC because for high powered setups it gives the lowest air charge temps and keeps them low when the car is continually pushed hard. We also have used air/water ICs and they work great at medium boost levels. However, since the S2000 has a pretty high compression ratio and also since we are building this as a very high power system, we decided to go with the highest performance intercooling system possible.

The boost profile we see with the MP62 supercharger is pretty flat but it does increase boost with increasing rpm. On our 220rwhp Miata setup for example, we see the boost starting at about 8-9psi at low rpm and then it linearly increases to about 12psi by engine redline. The effect in driving the car is it feels like it has a much bigger engine with a very similar torque curve profile as before. On the Miata it feels like you are driving a 3.5L V6 that sounds like a 4 cylinder . Also, we have found that despite the rumours of positive displacement superchargers not having as much top end, the hp peak rpm actually is higher than stock. For example, on the Miata the stock power peak occurs at 6300rpm on the dyno. With the MP62 the power peak is at 6800-7000rpm (depending on the pulley ratio and setup).

We promise to release videos and the full technical details as soon as they are ready. Tomorrow is going to be a fun day .

are these things loud? this is the type of blower cobras and minis use?

Not sure about how loud they are, but it is the same type of supercharger.

 

You can hear them, but only when you get into boost. If you're just cruising around, no one will know you have it.
