Turbo Guys Get Ready for the Big Mouth Plenum :)
Well the "legs" have to be the same to connect to the factory intake manifolds. This is the same on the stock piece, IPD, and ours. This diameter is about 78mm. The difference with the OEM piece is the inlet where the throttlebody connects. We are maintaining a complete 78mm diameter.
I posted up a ton of install pics here - http://www.vividracing.com/forums/ga...ages.php?c=484
Product looks very nice! I would love to see how this piece compares power wise to the IPD Plenum. I assume the "turbulence" is not a issue with this design? In your opinion will this outperform the IPD piece and if so why would anyone need the "Y" design from IPD if it does? Is the "Y" design really that effective? Lastly, you indicated nobody else does Y design because of the patent which would indicate to me that others would use the design if the patent was not there. Which leads me to believe that the Y design is superior...
If the patent was not there would you have designed yours with a "Y"?

Your "splitter" could very well flow more air than the stock and other after market splitters on the market.
Our recent air flow tests of the 996tt, 996 GT2, 997tt, 997 GT2 and the WC plenum ranked in order of best to worse 997 GT2, 997TT. Followed by a tie on the 996tt and 996 GT2. The WC out flowed all, however the flow distribution between the legs was poor.
Our tests determined small gains can be picked up with a splitter, however the splitter wasn't the restriction. It was the parts from the end of the splitter to the end of the injector manifold that were the weak link.
In other words on the 996tt and 996 GT2, the splitter can be great, but the other two parts (left alone) limit the throttle body and splitters potential.
