    Air Intake Expansion PB

    Hi,

    anyone got any suggestions for getting better airflow into the air intake?
    It seems to pull from no where but hot air inside the engine bay. I have pulled out the inner seal and its a little better but hesitant to pull out the outer seal as no weather protection and im not even sure about the inner long term. Don't want to cut a piece out of the inner either.

    Doesn't seem to be anywhere to really re route it unless you had a whole new intake tube made up.

    anyway just wondering if anyone has done anything about this

    cheers

    Agree, the current intake position sources preheated air from the front of the engine bay area but it is well protected form water ingestion and not too bad for dust, but those engines that source air from the inner wheel well suffer from greater dust intake and are more susceptible to water ingestion. There is always the option of fitting a snorkel but I do not know how much these really reduce the air intake temperature down at the entry to the engine since all air goes through the turbo which is very hot and then through the intercooler.

        FWIW i removed the 2 weather seals (1 under front of bonnet and the other attached to the grill
        ) and routed the radiator overflow pipe behind the intake on day 1. I also remove the prefilter from the airfilter. Note i replace my airfilter every service.

          yeah i know the snorkel option but don't really want to go that way. Don't really have the money even if I wanted to do it. And theres always what OJ said regarding that anyway.
          Looking more for re routing option at the front but doesn't seem much choice.

          Cheers OJ for the comments re dust, it is pretty clean under there and yes I agree good for water.

          Thanks BMN I tried removing those but yeah as mentioned not too keen long term and i definitely dont want to cut a hole around the intake area just for that.

          I was hoping someone had played around - looking at you OJ - and had a good effective solution

            I think there is more to be lost rather than gained by seeking out a cold air intake. For an EFI engine yes but for a Turbo CRD I see little benefit but am prepared to be convinced otherwise if someone can provide some data to support the changes. More to be gained by improving the airflow through the intercooler by using inlet side shrouding.

              wow has a snorkle fitted you can see the air intake temps on the scan gauge2
              i dant have a snorkle so i cant help
              but i can tell you stock intake temps sort off

                like many other vehicles that have had a performance update (cold air intake) is usually at the front of the vehicle like the challenger, which goes straight into the airbox (shortest possible path) ... the quickest way into the airbox/filter and then into the turbo ... I have seen more dust in a airfilter from out back travellers with a vehicle fitted a snorkel (except with a sock on it) ... then that of the front mounted air intake of the challenger ...

                there is also a debate about snorkel giving you ram air (like increase horse power) well yes if you are going over 120mph it may give you 10+ Bhp if it goes directly into the airbox/turbo

                NB whilst travelling in convoy keep a good distance for the dust to settle a little ... that's when the 2 ways are handy ...

                  No need to replace your airfilter every service (unless when you get a torch/light and you put it on the filter and can't see it when you look at the other side) ...

                  (an airfilter that is a little bit dirty actually stops a lot more dust) ... ...

                    The cleanest, coolest 'unrestricted' air entering the turbo is going to optimise performance.

                    Thanks for the advice LR but pretty happy with my service routine

                      Very much agree. You might run slightly cooler intake temps but I think that by the time it turns into EGTs, there'll be little or no difference. Likewise, I think ram air justification on snorkels is over rated unless your turbos starving.

                      For me, snorkels provide added insurance for anyone doing regular river crossings (same argument for extended diff/tranny/fuel tank breathers) and generally, pulls better quality air.

                      Just my thoughts.

                      Cheers

                        excuse my ignorance but wouldn't better airflow be of a benefit? Not especially seeking "cold" as I live in QLD where the intake says its 55 degrees anyway when outside is 35-40...
                        surely 55 degrees is better than 70 degrees which it is what it is before I removed the two rubber piece and re routed the radiator hose that sits in front of it though.
                        But I'm not sure how hot the turbo makes the air?

                        Thanks!

                            Hey,


                            Update....
                            well I don't know how my air temp gauge went to 70+ degrees the other day it was 40 degrees outside but today I replaced the seals and at 35 degrees it was only 56 on intake so still only 20 degrees difference.....about 3 degrees more than with the seals removed.

                            So I'm going to call the difference negligible and leave them in place until I have proof it will go higher again.
