Nialls supercharged GTi6 - project tidy up

[Niall]

You should try the 330 setup on mine with braided lines all round. It stops quicker than it goes lol.

Sounds like you've got a coolant or airflow problem there Niall. The thermostat is set to open at 83 degrees on a 6 so I'd be changing this as well as the rad for a nissens one. Also why are you using just water? Coolant helps extract the heat faster from the block (hence it's called coolant) and reduces hot spots within the engine.

I've had trouble keeping mine cool since fitting an enormous front mount last month (was on Sam's car) but have cracked it now and back down to normal running temps. Oil and water both at about 80 degrees and hardly go up when thrashing the arse off it.

Sam I've got some 406 brembos kicking about.... but not bells and rotors

Funny you should say all of that because today, progress!
Firstly, the stat was brand new genuine pug when the engine was built 1k ago and tested before it went in. It also opened exactly when the coolant hit 83 degrees today (had the laptop on monitoring)...

Anyway!
Nissens rad for this GTi was about £150 just because it had that poxy little pipe to the oil/water heat exchanger. Phoned around and eventually spoke to my local GSF who could get one in 2 hours. Asked for a discount and he said, err ok then how does £105 sound? Done!

Like a kid at christmas. Sad right?

Out with the old...and the oil cooler

And in with the new plus relocated oil cooler to behind the rad.
Seeing as i will have all the keyboard warriors on my case about the cooler behind the rad, let me answer that one now.
I was not a fan of cutting holes in grills for air flow etc and want to keep the front of it looking as OEM+ as possible so i phoned Mocal who suggested banging it behind the rad. Providing there is airflow over it which there is and its as close to the rad as possible so air flow Is maintained through the rad and through the cooler, it will be fine and guess what? They were right
Went for a drive after bleeding it all and coolant doesn't budge past 87 degrees (yes coolant now, not just water lol) and oil temp is also a tad below 90 no matter how hard i spank it. Speaking of which, I've just done a quarter of a tank in 45 miles but what a fun 45 miles
Oh and also now i don't have a hot oil cooler in front of my intercooler, air temps have dropped as well

Just waiting for my GTT charger coupler to turn up, replace that to deal with that god awful noise that sounds like horrendous big end knock (trust me id know...) and then she's good to go to pugfest
Also after shortening my push fit oil cooler hoses, one of them now has a slight weep so may have to take a trip to Pirtek.
