Mk5 General Area / Re: Reliability mods?

« Last post by Pudding on Today at 01:07:35 PM Started by probedb  »

Yep.  At this time of year, the under bonnet temps can get pretty severe after a hard run.  The pre-cat gets bloody hot.

Worth noting there's no risk of an EML after bashing the pre-cat out since the oxygen sensors are placed before the pre-cat, and after the main cat.  The ECU can't detect which cat is dead, only that ONE of them is.  If you do get an EML, that means the main cat is dead and the pre-cat was helping it.

Tbh removing the precat could help long term reliability as it reduces temperatures.

How many miles have your current dampers covered?

What's your budget?

What ARBs are you using Kev? Also, I've been chatting to Damian at DPM and looking to get the Powerflex Handling kit. Are there any other bushes worth changing other then what they advise?

Cheers

Hi mate, my full chassis spec is as follows:

Eibach ARBs (26, 23). Rear ARB on stiffest setting, front on softest.
Ohlins Road & Track coilovers - 50% damping front, 25% damping rear.
SuperPro 90 Shure console bushes.
TyrolSport Deadset.
TT front top mounts (stiffer rubber than GTI).
MK7 front calipers with Clubsport S 2 piece discs.
Rear completely stock.
Stock geometry.

That little lot is amazing.  It's hard to believe a humble Golf can drive so well!  I've been in far more exotic cars (most BMW M cars) and in all honesty, the little Golf chews on their bumpers easily on challenging roads.

I don't recommend poly bushes anywhere except the consoles, but take your pick from Powerflex, Whiteline or Superpro, they are all the same.  By all means refresh the other bushes with new OEM rubber, but don't fit poly.  Keep the chassis as predictable as possible and remember super sticky cornering in the dry doesn't always translate to predictable behaviour in crap weather.  VW did all that tuning work for us with their chosen bushes and geometry

Performance Modifications / Re: TTE420 vs TTE480

Shoduchi has the 420 on his and he loves it.  Looking at dyno plots, the 420 isn't much slower to spool than the stock turbo, and you get a much fatter mid and top end.

The 480 is a pointless imo.  For starters the stock engine cannot handle that kind of pressure and it's too far the wrong way into the lag compromise for a road car.  And also, once you're past 400hp, an extra 50 or so won't be that amazing.  I've been there and done it.   To make a worthwhile difference to your butt dyno past 400hp, you need another 100-150hp.

Look a little deeper into your options than just a bolt-on turbo mate.  Consider a MK7 Golf R engine swap.  You'll get 380hp from a remap with the stock turbo and its a much stronger engine than the ED30 unit.  When all is said and done, you might find the price difference isn't that great.  The Siemens ECU can be made to work in a MK5 keeping all your clocks etc working as intended, so it's certainly worth consideration 

Traction will always be an issue which ever route you take though. Bear in mind the stock turbo has the TC light flickering constantly over winter as it is!!

Funnily enough I bashed my cat out yesterday and I gave the turbo shaft a wiggle, and to my surprise, it's still within tolerance at 136K. Hardly any play at all.  I put that down to not running too much boost and regular changes of a GOOD oil.  I've changed it every 3K since I bought the car on 70K miles. Mobil 1 0W40 all the way!

And that's the key to it, you don't need mods to keep it reliable, just plenty of TLC and maintenance.

Bashed my pre-cat out and did some chassis tuning (ARB and damper adjustments) and it feels a tad keener to move and corner now 

I bashed the cat out a few years back on my original DP but it made no difference, but this time around it definitely has.  Maybe it's just the software differences.  I was on custom back then, but currently on Revo (stock mode).  I think the best reason for doing it is the exhaust note.  The extra bass around 1500rpm reminds me of MK2 GTIs from back in the day, and they sounded great on the factory exhaust!

@Pudding it was from VW main dealer. It was £96 which is crazy, but I only expect to do it once. I should have thought about paint or nail varnish on the ends; I may do that.
It was one of the 30 degree days, so was flexible enough, not too bad when you get in a flow.

FFS    It's generic trim cut to length!  Oh well, if that's the cost, that's the cost.  Thanks mate

From all that I have read, the 420 tends to overdeliver whereas the 480 typically falls short, so the power difference between the two may be more like 30bhp. I would however prioritise response / area under curve over outright power for a road car and let’s face it, our FWD chassis are rather traction limited. If you want 400bhp, you should be fine with the 420 or similar hybrid options from BBT / Owen Developments / Turbo Technic etc.

Thanks mate. Yeah been doing as much research as i can but it does seem the 480 falls short in some areas...people have had oil consumption issues with them also i have read. Im not looking for crazy power as like you say traction is an issue even now with my quaife fitted tbh. You hit the nail in the head....response is what im looking for. Most folk with them fitted seem to be on mk6 Rs and S3s.

Anybody on here running a 420 and can give me their opinion on going from 2+ and if its worth it?

Cheers
