Mine currently goes from the front of the turbo down through the manifold to the block.
I want to run it like the BDM kits, out the back and down to keep it away from the manifold.

I will check the prices of the hoses on monday for you. I didnt get a chance on Friday. Do you also need the water return pipe?
Just a price and length on the one down to the block thanks.
Can the length be anything i want?
Thanks.
Small update, had the car checked out at Euro Performance, had a sniff test on the coolant, compression test and leakdown test to try and figure out whats going on with the coolant issue.
Compression test: 13.5bar to 14bar across all four.
Sniff test: No issues with exhaust gas in the coolant. Happy with that.
Drop down leakage test: 15% on cylinders 1, 3 & 4 and nearly 30% on cylinder 2.
No idea whats going on with cylinder 2, valve not seated, worn etc... but i dont think thats anything to do with my coolant pressurising.
Anyway, Im going to:
Re-do the coolant feed/return
Raise the back of the bonnet
More heatproofing on the heater pipes to the cabin
And possibly fit a lower temp thermostat and fan switch.
Any ideas would be welcome. Thanks.

Generally like to see leadown test results under 10-15% and pretty even across the board, looks like there may be an issue on cylinder 2 mate, were they able to notice where the leak was indicating the problem area was? Possibly bubbling coolant tank ie headgasket break cylinder - water jacket ( even though the sniff says no )?
Dont think gareth could tell where it was coming from tho, didnt say any issue with the coolant bubbling. Said the car was an animal tho and coming from him whos got a RS4 thats not bad. lol.
Im going there after work so i'll get the exact figures on things but he does also think that secondary water pump might be causing an issue.
I'll email you later Craig.

Phil, just read this looks great mate

Just what I'm looking to do, may need your opinion on a few things.

MAP sensor changed andidle is pretty rough, think i need to do a TB reset to get the adaptions back to 0.
Car is still smoking on start up pretty bad, gonna try a different/smaller restrictor i think and i still need to re-do the return which i think is the problem but i have no idea where to start as i havent got a clue what fittings have been used.
Im slowly gettin less and less time to work on the car and its spending more and more time sat on the street doing nothing especially with a house i need to finish.
I also need new brake discs on the front as i found a massive crack in one.
And i still need to get a length of hose for the coolant to Alex @ Backdraft to sort that out asap.
At least the alternator is fixed.

i know exactly how you feel m8 its hard work keeping a car on the road let alone tuning it and sorting other bits out on it thats why mines in a lock up so i cant see it and it cant piss me off then haha good luck phil on getting the car sorted shall see you at got boost on sunday
Cheers mate.
Well i sorted the rough running.
I forgot to put the vac hose back on the DV. What a fool.

I know. I feel like such an idiot.
Drove it to work this morning, 1hr/30miles. Didnt put a foot wrong, drives nicely and pulls all over the road.
The raised bonnet at the back, although doesnt look great i dont think, has certainly helped air airflow though engine.
Will check my fuel trims tonight when i get in to see how theyre looking with the 3bar MAP sensor on.

Fuel Trims:
0.9% and 18.8%.
No idea why this is happening. Think i might change the MAF now as mine is about 3 years old at least.
Also difficult to get any sort of decent figures logging as its wet outside, so with hardly any engine load the fuelling might not be right, and im only running about 22psi where i want to be running about 26-28.

I was of the understanding that the long term/multiplicative fuel trim (18.8%) was a result of under load/boost?
As if its seeing less airflow than whats required vs a spec boost so adds fuel to compensate for lower airflow?
For example:
at 6000 rpm i get 22psi and 220g/s
But what the ecu thinks it should see is 18% more airflow for this boost and rpm, so it wanting to see ~260g/s . Hence the adjustment.
Or am i not understanding the fuel trim?

STFT / LTFT are normally a direct result of lambda feedback, in your case ( narrowband ) at idle and part throttle. I dont know if what you suspect will have any effect on fuel trims, i doubt it, but im sure Bill will confirm/deny.
Try a smaller MAF housing, increasing measured airflow by 10-15% and report back your ST/LTFT values.
If your running too rich at WOT, decrease 'Primary Fuel Tweak' value in lemmiwinks ( channel 10 )

By running a smaller MAF my AFR would be the same tho when it adapts? But my trims would be closer to 0 as the flow would be higher?
Yeah i tried that Craig, AFR wise it works but eventually throws a lean code as the adpation drops by what you adjust it by on channel 10.
I dont see how it will adjust back out with unisettings, so underload its ok and idle/cruise is ok also, when they are at opposite extremes..
what size maf sensor are you running again Phil?
