I found mine felt better in the corners with the factory rake removed, i.e. lower at the back, and also better under braking.  That's road use though, but often what works well on a fast road car usually translates to the track as well  :happy2:

Yeah not paying nearly 1000 pounds for that sorry! With all 2nd hand injectors out there getting on in age I imagine though it will be a fairly common practice now for many tfsi owners as only a small percentage are going to pay those prices for what is considered now to be a cheap-ish car most of the time.

Lower COG maybe outweighs the extra front grip/loose rear that large rake gives...

Yep it's ridiculous. Injector replacement plus Walnut blast is getting on for a £1500 job now  :stupid:

The rake is mainly there for high speed stability and rear load capacity on FWD cars, neither of which are particularly relevant to a track car  :smiley:   To me the car feels better balanced with the rake shifted, and indeed all FWD cars I've owned...... in the same way the car feels more planted after filling up the tank.  Rake feels like lifting up a corner of a table on turn-in, very tail led, but levelled off, the whole table corners at the same height, it's more front led and the rear just follows faithfully rather than influencing..... really bad analogy but hope it makes sense  :grin:

Yeah rear load capacity was my thinking. Mine is set on almost the lowest setting on front and not far off that on the rear and there is some natural rake anyway. Was just watching the mini challenge cars last weekend which have crazy amounts of rake and got me to thinking!

Injectors came back from RTech along with some branded sweets! Nice aye.



The hpfp been driving me crazy lately, just constantly leaking, ended up replacing the rubber hose and bamboo connector which connects the low pressure fuel line to the hpfp, 45 quid for that tiny little brass union :surprised:



I replaced them as it was leaking quite a lot thinking I'd messed something when removing but the new one still leaked annoyingly! When I took it off originally I could have sworn I saw something fall out of the hpfp, I tried VW and Aks tuning and both were sure there wasn't any kind of washer there and nothing they can see in the diagrams and nothing they stock or sell. I decided to just get some m6 nylon washers from b and q, fitted one and boom no leaks! No idea if it's just mine that needs this for whatever reason or if all hpfp's have this but it's just not listed. Drove me a bit mad anyway taking it on and off god knows how many times.

And now it's actually running it idles so beautifully when the injectors have just been cleaned, never lasts long I've found but is satisfying :grin:

It's going to be fun stripping this thing down after Llandow, if anyone wants interior bits let me know. Not going to be fully stripped to keep it relatively safe still with oem seatbelts and air bags but anything I can remove without impacting safety or air con will likely be removed!=

pudding:
Yes mate, there is an aluminium washer under each brass fitting apart from the schrader valve one  :grin:   Everyone makes that mistake  :grin:

Glad it's sorted for now, but you will need to get the proper washers in there at some point  :happy2:

I could do with a few interior bits.  Let us know when the great strip down commences  :happy2:
