here you can see why aliepress is cheep, the end tanks are slightly wonky but with the bumper on you cant tell. i still need to pressure test the rad and intercooler to make sure they dont leak

I thought there needed to be a bit of flex and movement on the radiator and intecooler mounting to avoid cracking when hitting bumps or ripple strips. They are quite fragile. Normally a bit of rubber works or mount on something that has a bit of flex.

Looks like we are both doing similar things (well my mechanic is). Decided to go with the Bell intercooler and radiator cores - quality is nice and they are to the mm as what we ordered. Service was great too.

that looks bloody good. there will be rubber on the rad mounts for abit of movment but im taking the risk with the intercooler.

not quite as profesonal looking as yours but im doin my best, i really like giving it ago. it might just blow up when (if) it ever makes it back to the track haha

mounted the oil cooler today, just have to get 2 -10 90s to curve around the radiator then i can plumb it in to my sandwich plate.

does any one know if it would be better to have the oil feed go to the top of the cooler and drain back from the bottom or will it not matter. i have a thermostat plate so wont be working all the time

Genuine Wishiwoto? I plumbed my oiler cooler with the inlet at the top and outlet at the bottom, seemed like the logical way to me.

The main thing is to ensure you control the airflow through all the coolers with suitable shrouding and ducting.

yeah im going to make aluminium shroulds to force air through, or carbon fiber if i feel fancy. i did what alot of people do at the track and removed the nose panel, believe it or not the air comes through the bumper hits the rad and goes straight out were your nose panel usually is. so i noticed the car ran hotter. im not going to run a nose panel but will have shrould to stop air coming out and also allow air through were the nose panel was

i ended up going the cheaper option and getting autobend to bend up the tube for the tube front, it turned out really well so i cut it to length and welded it on to the plates .
the prop sitting on the oil cooler is just temporary till i add the two braces that will weld to the intercooler mount rail and also pick up the tabs for mounting the bumper
