    Is anyone interested in some turbo inlet pipes? Stock/Upgraded Stock

    A feat that has been attempted many times before. I'm trying to gauge interest on a set of turbo inlet pipes. I have a them on my car (still waiting flywheel) @rick@defiv made, they use two equal length inlet runners to a y pipe (prevents one turbo from fighting the other) with a filter positioned in the lower passenger-side brake-duct air vent.

    This is basically the 'ideal' for cold air induction.

    To install you have to remove a lot of stuff, you have to shuffle things around, it's a tight fit down there.

    After looking at the intake system Rick identified a few weak points, the inlet pipe at the turbo inlet has a restriction that is -smaller- than the diameter of the turbo inlet. That had to go. The pancake piping, sharp bends all had to hit the trash as well.

    Advantages:
    Short, equal length runners w/ gradual bends.
    Cold Air.
    Thermal Coating.
    No restrictions all the way into the turbos.

    I'm on stock turbos, I still expect to see some significant gains from this intake. You would imagine that upgraded turbos who are starved for air with the stock pipes will see an even better result.

    These tubes are done, they're on my car. I haven't had it on the dyno as I'm still waiting for the 6-bolt clutchmasters to arrive.

    Of course! (these are prototype pictures bros)

    Any pics of these before they were installed so we can actually see the full piping?

    Also how did you made room I thought the oil cooler took up most of the space in that area.

    The oil cooler is on the other side. Prototyping finished up on car so they haven't been removed, just interested in seeing if there's enough interest in the idea.

    ** sorry that's incorrect. No the oil cooler doesn't interfere with the piping or filter.

    Best way to see their effectiveness:

    1) Tap the stock intake pipe post filter and install a differential vacuum gauge
    2) Run the car at Xpsi and get some readings off the vacuum gauge
    3) If you see more than about 10" of vacuum being pulled at the intake pipe you'll have gains going with larger ID piping or a better filter. This obviously assumes the filter isn't the one that's imposing the restriction.

    I've been trying to get this done since forever but there's always something that gets in the way of it Click here to enlarge if you can get some of this data gathered we'll know their effectiveness without a dyno

    I'm interested, but have a large Setrab oil cooler on the passenger side and an auxilliary radiator on the drivers side. Fear that I wouldn't be able to fit the filter.

    and just to confirm you have a before dyno run so we can clearly see run before and after with just this mod?

    Didn't go into it expecting to make a product, I have a before dyno but that was from a while ago (4 months old; re-tuned, intake, clutch etc different) in hotter weather. I don't think the community would accept it for a performance delta.

    For a real delta rick would have to have another car come out to get fitted with pipes with pre and post measures taken.

    Any more details on the bend at the rear turbo? It is extremely tight there and it seems that the radius would be even tighter here. I am really interested in small mushroom or cone filters at the turbos.

    It was honestly one of the most difficult things I've done in awhile. It would need to be replicated in silicone to be installed for those without a taste for self abuse.Click here to enlarge Anyhow,yes I have every intention of putting a vacuum gauge post filter. Filter size isn't ideal for RB's and the like due to space requirements atm, but I'm looking into something "formable"(a Uni filter with formable caging of similar) to maximize surface area for upgraded twins. I think it's pretty close for use with those little pea-shooters that are on there. Tubing diameter is 1.750" off the turbos and then steps up to 2",which Y's into a 3". Brake duct is modified to collect a cold air source. I think It will provide the most gains at high speed, with the cool air charge being much more directed. We shall see!

    hey cool. i'm also in for results. i also believe the gain will be noticed at higher speed (air) versus a stock intake system. once a true delta can be established (thanks uniter for being honest) this product will gain much more interest. locals to rick should get the ball rolling. unfortunately, i'm in the same boat as neil, i have the upgraded setrab oil cooler in the passenger duct.

    Click here to enlarge There are a few people who came out Rick's way for the Defiv lockdown. Basically once my car is running we'll be doing some logging to see how it's doing, how the turbos are operating now. If the logs look better than my last tuning logs then we'll know that we've got something to go on.

    So I do have valid and recent procede logs, but i don't have dynos. I can re-create the same logs on the same tune on the same stretch of mexico and see if we can get any useful information out of them.

    Tubing dimensions sound good even for upgraded turbos. Anyway you can build taking the OEM path though? With this design I too am concerned about the rear turbo tight radius feed with the heat on another yet smaller scale. For the most part these should unleash a more efficient less strained turbo and shaft assembly, allowing for more airflow potential (likely very large amount on upgraded turbos). I really don't see much gains happening comparing lower boost to the same boost on newer pipes. More so the increases will be more potential in the turbos.
