The Problem With Pod Filters...

Just fitted a temp gauge with a sensor mounted next to the pod filter, driving at night, stopping at lights it reached a max temp of 65.5 degrees, hate to think what temps i'd get being stuck in traffic in midday :D

CAI is now priority one :)

Anyone get similar temps???

theirs an easy solution to this, make up an alluminium shroud and place it just behind ur front bar, dont block off the radiator if u can and then run some ducting from the shroud to the front of ur pod. or perhaps just case the pod off because it sounds like ur getting heat soak

A CAI isn't much good if your pod isn't heat shielded.

While a CAI might help drop inlet temperatures once you've picked up speed, it won't do much in stop-start traffic and you'll still get some heat soak.

I've used one of those laser spot temp things, and after a fair weather session at Wakefield there's been a 15-20 degree differential between the engine side of my heat shield, and the metal ring on my pod.

This is what my setup looks like:

(The other side of the flex pipe is in the front air dam, so its directly in the airflow)

However, around town there's not much in it. While I haven't measured it properly, touching the heat shield and the pod's ring doesn't bring up a noticable difference when I get home after going to the shops.

Isaac, if you still have your Airbox, Cut a hole in the side of that for the Piping from your Pod to the Turbo, and Stick some heat proof shield stuff on the inside if you can. That may help with the heat issue. But yeh as intensevil said, it sounds like heat soak.

If you are that worried about it just swap your pod back to the factory airbox. I swapped my HKS Pod filter for a factory airbox with K&N Panel filter and couldn't notice any change at all (and neither could a dyno).

The other good thing about a factory box is that it's perfectly legal unlike an open pod filter.

Yeah i treat shielding as part of CAI, so gunna do both and measure the results.

Still have the stock airbox but no snorkel, so it pretty much would still be gulping hot hot air (remember the airbox inlet is on the engine side aswell).

It doesnt help much that my turbo doesn't have a heat shield too, might get one of those turbo bags..

i just got made up a heat shield from aluminium from bunnings covered the engine side and the top of the filter, and with the old hole from the stock cooler i ran some flexy tube stuff fromt that hole to the meshed vent in my front bar.

the temperature of the pod filter itself and air intake will be different to the temp of the air being sucked into it. of course being in the engine bay the air will be much hotter than ambient air but if your temp probe is attached to the pod filter or intake piping etc then it will be showing the surface temp rater than the air temp.

Temp sensor is mounted in the surrounding space of the pod filter, not attached to anything bar a long cable tie used to 'hold' the sensor in the airstream about 3cm back from the probe, its at least 3cm from the pod itself and probably at least 10cm from anything metal (piping, engine bay etc..) so reading is as accurate as i could make it..

i hope you didnt move your AFM with it...

If you did, therefore changing the amount of air between the AFM and intake, then your computer is reading the wrong thing that the AFM is tellin it.

cheers

nah mate, the AFM its an air flow metering device, it only measures air when its flowing through it, so it doesnt matter if you have it closer or further away from the throttle body as its still measureing the same amount of air.

hope this clears this up

after putting a POD on my car, i noticed it was smooth/quicker reving at HIGH revs, but low down is really really bad and slow... i want to go back to the factory box.

and i think a factory box with a high flow panel is perfectly good untill you start making some real high hp

      Are you an oil nerd?

      By Kinkstaah · Posted

      I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet.

      Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.

      Mistakes were made, my R34 Story

      I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
