White "Lion" Cupra - DSG converted track car

[Shoduchi]

I'm glad you fit your DSG oil cooler with the proper bits to make it work well. Now you have more time to prepare your car better.

I was ready, some of the opponents not... 
But this is not the way I want to win and safety comes first, there are literally lakes on the side of the track now.

A dirty car with a big gay wing:



Clearly I need spacers for the everyday wheels, but I'm quite out of funds and never liked the idea of spacers.
More important is that I still don't have constant 130 bar rail pressure, on the medium rpm it sometimes drops to 110.
I've changed the RS4 fpr, no improvement. Now I've disassemble and resemble the HPFP. Tomorrow I'll do some logging...still hoping I will not have to change the pump. 

[Shoduchi]

Will the rear wing supports hold the downforce without bending the rear wing spoiler? Seems a bit too further away to really hold much weight.

Are you getting any ignition timing retardation when the rail pressure drops? Or a too rich air/fuel mixture? Or is it the other way around, and the boost drops to compensate the lack of fuel?

[teo_parvu]

Heylo! The roof of the car has been hardened where the mounts seat, it can hold my weight now, l’m a bit concern that it could develop play on the long term. The guy who installed it sais that it is highly unlikely.

I have no missfire, boost is fine, It holds 1.2@7000 rpm, no timing retardation (that is absolut perfect 0.0.0.0). Good ideea to check the AFR. Before the new software the boost demand dropped at high rpm, maybe there was a lack of fueling, but now i have RS4 injectors and Bosh LPFP.

Got a bigger problem now...I'm glad the race has been postponed. My clutch started slipping while doing logs yesterday so I'll leave the pump problem for now. First I thought that I have no grip because it was really wet and that the wing creates so much drag that I could barely reach the end of fifth gear. But today on dry tarmac it was clear, the clutch is gone.

I really need some help to get the latest revision OEM clutch for DSG 6 DQ250. Anyone can help with the code? Is the Golf VII R DSG clutch compatible?

Only from the 7R, since the 7.5R has a DQ380 with 7 speeds. You'll need to get a new shims kit to put the new clutches with the factory slack. Check the video on the 3:15 time.

Thanks a lot man! 

Do you know if the shims kit comes with 02E398029C?
I still don't know if I have a clutch or mechatronics problem. Now it slips, goes in N and jerks on R an first gear. I'm suspecting the mechatronics now, but I've called one of the best DSG specialists and he told me that we should see errors on VCDS for mechatronics and that I could have too much oil in the gearbox.
 

[teo_parvu]

After I've taken out 1L DSG oil, the car behavior is a lot better but I've found metal filings in it shining on the sun.
I've decided to change the clutch pack, oil and filter as soon as possible so I'll have some time for at least 200-300 km of city driving before the race.

Nothing gay about that wing, it's a track car 

Spacers - yuk, hate them.  Research 'scrub radius'    Always better to do proper TT wide track with arms than throw spacers on 

Fuel pump - what HPFP do you have?  How old is it?  Could be a dying LPFP.  Pop the HPFP out and smell the oil that gathers in the chain cover casing.  If it smells of raw gas, the HPFP piston seal has gone.   The trouble is VCDS only measures pressure, not flow, but as your pressure is down 20 bar, it's not looking good 
As Shoduchi said, see what the short term lambda is on hard boost.  If it's pegged out at +25%, time for a new pump.

Good luck with the clutch pack.  Your hard track work is killing your hardware 

[teo_parvu]

Thanks man! 

I've improved the looks of the wing by wrapping the aluminium legs and using different end plates. I quite like it.
Since I have to move the car around the city it is unmounted now. I don't want to find out what is the police opinion about it.

I already have the TT arms, but I'm using 9J wheels for the track, same ones used by the Milltek VW Cup. The street wheels now look a bit funny under the widened wheel arches.
But I don't want to mess with the scrub radius that I believe VAG has researched with spacers, I'll leave it as it is. 

The HPFP is my original one upgraded last year with Autotech internals after the chain between the camshafts broke and took my APR pump with it. My friend reinstalled the internals this week, it seems to operate better now. I had the opportunity to do some logs, I'm 5-10 bars down only when the turbo loads, when it overboosts. I didn't log everything because after the DSG decided to go in N I took the car home quickly.

Next week I hope to have the new clutch in, something I should have done before fitting a 100K km old DSG into a track car, but I thought I'll get away with it.

Some spirited driving today, the car behaves superbly.

That looks the nuts mate 

[teo_parvu]

Thanks man!

I’m really happy that with the new clutch pack, it’s transformed. Thank you Joaquim for the video, it really helped to calculate the shim thickness correctly.
I'm still medium boost until I'll get a software update. It seems that a lower torque value could've been sent to the DSG software. That could be the cause for the fried clutch.

Today I've received the new ATS wheels, they look beautiful: 

Hi Mate, where did you get these from? Struggling to find them outside of Germany.
