We did a twin turbo kit so why not a Twin supercharger set up, something different and fun to do. We wont make less power, The Smaller Rotrex chargers have up to 80% efficiency rate and this chargers has minimal parasitic draw. So far the rotrex units have met and exceeded our expectation in all aspect . I don't think we will be disappointed. Also we wanted to take supercharging the VQ37 platform to a complete different level and mainly offer all our AWD customer a good solution.

I personally think this set up will be inline with the twin turbo kit performance, We will see .

Good thing you went with those GTX's Turbo upgrade

Please educate me on this setup ... So it's two identical superchargers, just one for each side? Please explain the benefits of this approach. Sounds very interesting!

Great work and very impressive as always.

Question though, how is this better than having one single supercharger or twin turbo instead?

Ron · 02-25-2012, 08:54 PM

I wasn't trying to be rude. When u swap pulleys you are changing belt size as well, this determines how fast the engine is spinning the SC, how can a you regulate that without changing pulleys and belts? Again not trying to be a smart***. I really don't know how to.

Develop a valve that vents when a certin boost is hit. Install it before the maf sensors

Not a bad idea, twin wastegates for a supercharger.

toner123 · 02-25-2012, 09:30 PM

Thats what I was thinking because then you can always run the smaller pulley and just control the boost. No more switching pulleys and belts with a retune and being unable to regulate boost other then gas peddle
