I think it'd be fine, I've run filters in similiar positions down low but up in the front, totally exposed to the elements and never had a problem. This is no different then many cold air intakes on cars. Of course, don't go flooring it through any streams

I was pretty excited. mark what did you do with your MAF?
My car has a custom MAF with a bigger MAF housing...

I don't understand why anyone would want to replace the diverter valves with blow off valves. Isn't the purpose of the diverter valve to recirculate the boost system with the unused charge? Why would anyone want to release the pressure in the atmosphere rather than recirculating it back into the system and really help eliminate turbo lag? IMHO, it would be better to keep the system pressurized and reduce the amount of "work" on the turbo's to recharge the system. Less work on the turbo's = less lag.

Conceptually, I think it's a pretty cool idea. I would imagine spool time would be crazy quick. A lot of you guys know how the V-Flow increases throttle response and spool-up. Imagine how this set-up would perform. Great job of being creative and thinking outside the box!
ITBs have been done on 993tts for a long time if Im not mistaken...

"Forced Induction Performance Tuning", by A. Graham Bell
1. Blow off valves s/b between the compressor and the intercooler - not after the intercoolers. This significantly increases the efficiency of the intercoolers, by allowing the intercoolers to only cool the charge that will be used by the engine.
2. Recirculating hot/compressed air into the compressor reduces efficiency and raises inlet temps.

WARNING STUPID QUESTION:
I am not a mechanic and I know it but I have a question none the less.
Would there be more heat around the 9FF intake due to its proximety to the engine, the turbos, and the brakes? I know whenever I have worked on my car the second you get close to the back of the car its steaming hot back there. Maybe there is so much air flow it doesnt matter, but I feel like the "protomotive" setup might have colder air.
Idk just a thought/question

Once the car is moving anything faster than a few miles an hour, the intakes have access to the greatest source of cold air...air completely outside the car (next to rapidly rotating wheels)
The other setup gets some cool air for sure...but there is more resistance introduced by the significant distance to the cold inlet via a relatively small caliber tubing. An additional point to consider is how much heat the piping retains. Remember resistance increases linearly as the lengthof the tube increases, but exponentially as the radius increases...In other words - the lowest resistance fluid circuit is one with the shortest, thickest tube.
The protomotive "setup" also creates a new flow variable by introducing curves (more resistance) and the resultant dependence on laminar flow to increase efficiency.
while the protomotive setup *may* be superior to stock - the turbos are STILL seeing a significant intake restriction compared to the filters fitted directly on the cold side.
Oftentimes, the best solution to a given problem is the simplest.
This kit is certainly not for everyone. Its for the driver who wants his power in a different manner. Sure there are technical advantages to BOVs, but this setup was created for customers who demand something extra and unique - but still demand a completely engineered solution replete with advanced programming (and that PSSSSSHT sound).
The power change is certainly different - different, immediate and powerful. You don't need to be brain surgeon to understand the advantages of a setup like this, especially when combined with custom 9ff turbos. Plentiful cold air, lowest restriction to flow...and BOVs!!
The "cost-conscious" members can take heart in knowing that the kit is a no-cost option on the 780, 840 and 910HP sport motors.
