Stock style large inlets vs fender/intercooler inlets
I think the EVOMS inlets pipes only flow 6% more than the stock inlet pipes. (remember reading it somewhere, probably on their website)
The fenderwell intakes are in front of the intercoolers sucking all the air and dirt.
ESMOTOR carbon rear wing intake has the best of both solutions.

Emailed him and no response as of yet.
I am leaning toward his fenderwell inlets as I don't have to cut a hole in my car and it seams like it does not cover the face of the intercoolers.
Is there a direct number to reach him?
I don't *think* it is the inlet pipes or anything to do with them, but at this point I'm not ruling anything out.
I'm tempted to order a set of these and swap them just to see if my problem goes away since the price is (for once in the Porsche world) borderline reasonable.
I don't see how this is possible, the factory inlets are so small you could barely get a stick of bubble gum through them in a couple places. Maybe with these on the market EVOMS will actually put a realistic price tag on theirs, since they are charging 3x as much.
The fenderwell setup from Proto is actually somewhat reasonably priced. Just a little more than the EVOMS but waaaay less than the Champion carbon fibre piece. However, since I dd my car it sees rain etc... and I understood that the water would splash onto the air intake in the fenderwell so that's the main reason I prefer not to do it.
I'm ok with the fender well setup, but I would build my own for about $350 rather than buy one from a vendor. Maybe a little more if you had the pipes powder coated crinkle black or something. Maintaining the factory airbox would be my first choice. It's a *great* cold air intake and you don't have to worry about water ingestion.
Hello Bobby,
I just saw your email, as you sent it to "INFO" address, not mine.
I will reply in 1 hour as im on the road for tuning.
BTW, 991 TTS inlet pipe placement is similar to what we done.
There is a second hole in the engine bay already from the factory
Regards,
Emre

I used to have this set up. Now, my airfilters are connected directly to the turbos. I never drive in the rain, so I'm ok with this set up.
That set up seams to be the most efficient for performance and cost!
What about dust and is it possible for it to get knocked off?
I do not drive in the rain, but if I do take my car on a little trip, this is something I do not want to worry about.
Emere @ ES MOTORS thoughts of Fenderwell set up vs separate intake :
"
The problem with fenderwell intake is they work fine with short acceleration runs but they fail with long runs…
I tested them so much…None of the intercoolers work well with fenderwell intakes.
Thus we made a kit with modified stock airbox at the back, which gets fresh air from the rear wing, like stock car…"
ME:
This is very valuable information that is tested and this is the exact thing I feared when looking at the design!

just a side note, i dyno tested 2.5" inlet piping on my 996tt and at 500whp it made zero gains BUT at 850whp it was robbing a lot of whp and spool. 997tt inlets are a better design since each turbo get its own access to the panel filter. i would expect upgraded inlets to work perfectly with anything up and thru a GT30 sized turbo as far as air flow goes.

For now I was thinking of doing just the air filters as I do not take my car out in the rain, until I figure out which way I was going.
The question is how much of a restriction (power and spool up) do you think something like the "EVOMS" inlets are vs straight airfilter/fenderwell intake at the 700RWHP level (running ungraded VTG's)?
If it is not much of a restriction on the 997 with two separate inlets, I like the OEM and simplistic nature of the stockish upgraded "EVOMS" style inlets.

So does anyone else think that upgrading to just the EVOMS style inlets would NOT rob the car of HP and spool up to 700RWHP?
Also just for testing purposes, I am thinking of just putting on airfilters straight on my turbos and see the 60-130mph differences compared to stock at my level of mods (as I wait for all my mods to arrive) and being the Proto tune I have is actually a Mafless tune.
Does anyone know what size filter I need and or part number for K&N's etc?

my 996tt has it set up like that but its standalone and mafless.
filters on turbos is the cheapest way and least restrictive. the drawbacks are that i have o clean my filters ever 1000 miles because they are right above the ground and get dirty very fast. on my 997tt i will use upgraded inlet piping to retain factory filter location.
just a side note, i dyno tested 2.5" inlet piping on my 996tt and at 500whp it made zero gains BUT at 850whp it was robbing a lot of whp and spool. 997tt inlets are a better design since each turbo get its own access to the panel filter. i would expect upgraded inlets to work perfectly with anything up and thru a GT30 sized turbo as far as air flow goes.
I compeltely agree. I have been saying it for years and all the people running proto setups tell me im crazy and that it doesnt make a difference. The heck it does ! Our ICs are not in the best plase as it is and your gonna block whatever air they are getting lol, if you are blocking your intercooler with a big cone filter your post IC IATs are much worse. Post IC IATs make the difference.

I think these would be fine at ~700whp. Not sure why you say RWHP, unless you are talking about a GT2. In any case, the AMS ones would be better as they are considerably larger. I have both the AMS and Do88.se pipes at the moment.
I'm not sure if AMS is selling them separately from the kit at this point though.
I have no idea on the K&N part numbers, but measure the OD of the compressor inlet and then look for something close in the K&N catalog. Can't be that hard to figure out.

I appreciate the advice, but the last time I read one of the members were having problems with fitment with the VTG's.
Since we are being so specific, let me rephrase "700AWHP".
