Intake plenum
Hahaha i don't think she had any idea what to expect .......... needless to say when people started gathering around the BS after we got out and started taking pictures it totally caught her off guard. 
I just told her they were taking pictures of her.

Wow ....... that was wrong on so many levels. Pour salt into an open wound ....... Wow todd. Revenge will be so sweet.

I know. I know. I don't know what came over me. I really am looking forward to seeing what Proto can do with those turbos. Steve is going to work on my boost leak Monday.

btw, it doesn't require engine drops, just need a pair of small hands.

"The management of induction tract resonances is critical to maximizing the power of naturally-aspirated engines, but the turbocharged engines have typically foregone this technique in favor of adding additional manifold pressure (resonances in a pressurized manifold are also extremely tricky to tame). Cranking up the boost has a drawback, however, in the form of additional heat, and so more fuel and less timing is required to maintain acceptable durability.
Porsche claims to have countered this with an "expansion-type" manifold that makes use of the typically-unused oscillations that are still present in a forced-induction manifold. A longer and smaller-diameter primary tract is combined with more plenum volume and shorter individual cylinder runners to yield a cooler intake charge for a given flow rate, which means that the fuel mixture can be leaned and more ignition timing can be utilized. Both changes improve fuel economy and dump less heat into the exhaust system - undoubtedly a win-win scenario. Amazingly enough, it all fits in the restrictive rear engine compartment of the 911, and we expect to see this on future forced-induction engines from Porsche."
And yeah Todd, I think I have one in the garage somewhere...I was going to install it but then had second thoughts, but still might...or maybe sell it...if I can find it.
