That's right only so much room to work with in there.

very interested in numbers and pricing!

I'd guess pricing is close to the cost of TT kits.

Probably more...well not probably most likely more.

Well if that is the case then the gains must exceed TT kits. Not necessarily meaning more power or torque but no lag and a flat torque line on par with TT torque would be awesome.

Nothing about twin centrifugal SCs is going to change the fact that they still make power in a linear fashion and *probably* aren't going to be able to match the torque output of a twin turbo setup. Because in most centrifugal type applications, boost is limited by RPM rather than by an active system (e.g. wastegate), having two smaller chargers will not necessarily give you the benefit of being able to spin them up faster and then bypass the extra boost (like a turbo).

If you want turbo-like torque from a supercharger, you have to go with different designs like a roots-type, twin screw, etc. These make significant boost at low RPM, but lose efficiency towards the top. With our V-platform and the intakes runners on the inside of the V, I actually think that such a SC would work well, but my guess it that space constraints are the problem.

With all this said, I am very excited to see the kind of results this kit puts out. I haven't seen any twin SC setups before so I am very curious about the performance.

Wow guys. In for updates.

LafitteZ · 03-05-2012, 11:24 AM

Yea Its a big power no lag option for the vq. It will be much better on the drag strip for sure. PLUS THE COOL FACTOR!!!!! Will It be possible to get these things chromed? From the picture I looked at in the beginning it looked like the chargers will be up top.

we'll see this does seem very promising as it would allow them to simplify the piping since they won't have to go around an engine mount, and should have an increased output throughout thanks to the new compressor options.

All this over some damn plugs?

On another note, I can't wait to see this thing in action!
