Mk1 golf 20vt high intake temps

Hi all 
        Now winter is here decided to try and fix my high intake temp problem were the bottom of my intercooler isn't cooling. Dose any one have issues or experiences with this problem? I'm also looking to move the battery to the boot to give the air filter more room to breath.
Any help or advice about this would be great. 
Cheers steve

I've had this with mine.

Bad installation from that start with guy who built it.

I moved the battery location to the drivers side and fitted a slim race battery.

Moved the air filter from the drivers side, it was right at the side of the hot head to where the battery was. It now has loads of cold air from behind the light.

Increased the intercooler size by three times the size of the one fitted.

Then I re piped it all for the shortest run.

Hi daz we spoke before after the map. What are your core dimensions on your intercooler?
I was looking at getting a smaller one because the bit witch sits behind the metal piece of body work under the grill the intercooler is warm to touch. So I was looking at a 550mm x 140mm x 65mm toyosport. Do you have any photos?
Cheers steve

That core size sounds about right, it's a toyo sport one too. The outlets are in a good position too.

You will have to make some alteration as it pushes the radiator further towards the engine.


 



The cooler sits about one inch off the cross member and about an inch lower than the slam panel, and pretty much full width.

You will have parts that are blocked by metal work but nothing you can change about that unless you put the cooler on the outside 😳

I've also ditched the swirl pot as that was wrong too, so im going to try increase the air intake pipe to 3" and make the pipe shorter.

The intercooler core I'm running now is 550x160x65 and the bottom is warm to touch as I said it blinded by the front of the car so I'm hopping smaller in air flow is better than bigger with some surface seeing no air flow. Your car looks well I like the rad cheers for photo

I've put a lot of hours into this car now.

I'm not sure a smaller cooler will give you cooler intakes? However i do understand where your coming from in that the air gets lost in the bigger cooler?  What's you engine bay look like now?

How about meth injection to cool intakes down?

What boost are you running?

I'm running 21psi boost 2.5" pipe 5 bends and a 63 degree for inlet manifold also I still have the battery under bonnet so the air filter is blinded behind it so moving that's also on my list. I don't fancy meth but last resort might be. The problem is the mk1 only lets air in at grille level and nothing in the lower bumper area.

I'm also running 21 ish but now gone from a ko4 hybrid to rs4 hybrid so needs mapping again.

How high is the intake temp??

Have you a photo of your bay?

Intake temp is 72 degrees at 238bhp and 60 degrees at 232bhp photo don't show pipe now runs between bulkhead and expainshon bottle.

I think I'd do what your thinking and get thr air filter right up front.

Everything else looks ok?

Does the turbo to intercooler pipe run similar way to how ive done mine?

hybrids do run hot . my runs hot on full boost. water meth has sorted that out

your set up same as my same filter postions cooler ect

water meth took my temp to 29

Just a thought.. I've had good results with a Phenolic intake spacer (cheramic). It brought the AIT down almost 10 degrees. Car was a S3 8L 210 with Dalbäck intake, Forge FMIC and 3" piping..

I've fitted a carbon air box to mine along with a large intercooler/rad and a ceramic coated downpipe which cools under bonnet temps….292bhp and never had heat soak or high intake temps :-)
