Polishing Intercooler piping

I have polished up the intake pipe to the plenum pretty well and its now nice and sparkling. I really want to do my intercooler piping too much and thing it will come up really nicely... just a quick question incase it is a bad idea..

My question is: its HKS piping and has this sparkly silver crap on the top. Does this form any sort of special heat protection or is it just a form of silver paint to make it look slightly better from the factory?? If its just sparkly crap and serves no useful function, i'll sand it off and buff it to a mirror finish.

Does this silver stuff has any special properties i don't know about?? is this a stupid move just for the sake of vanity??

To be honest, I'm just going to probably heat wrap the ****ers anyway because i'm getting a bit of heat soak across the piping from the engine (so i've been told).. so if i polish them and later on wrap them that all fine??

Sounds like you have the same pipes as me, and i think the material is actually painted mild steel.

Dont believe there is anything special about the paint, however you wont want to be polishing mild steel, the finish, durability and corrosion resistance of the piping will be compromised.

hmm.. Part of it had worn down and I sanded back a small bit.. Seemed like it would come up quite nicely though? I'm not sure now - i am sure it couldn't suffer too much, you are only sanding off a tiny bit, its not like you're taking mm off the walls of the piping.

Maybe i should leave it then?

im planning on sanding mine back, polishing it and spraying some clear epoxy to stop it from rusting

i had polished of one side of the pipe and noticed some rusting to form

was told to either coat it with this epoxy stuff, or just get some anti rusting spray that they welders tend to use and just spray it over with gloss black paint

*shrugs*

well see when i get the change to do it

but yes, that cross over pipes gets a fair bit of heat soak, when i feel the outlet pipe from my intercooler it ice cold, yet my intake temps are registering (thermometer is just located before the throttle body) ~8-12degrees abover ambient

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
