Roomster 1.9 Tdi modifications

Nice thread. I don't think you have to be qualified to give advice, that's why it's advice and not a paid service. It's up to you how you treat that advice.

Just a quick comment on brakes, for my Polo GTI with same brakes, Bendix ultimate are quiet and very bitey. I wouldn't want to track them, but for daily driving, they are very nice. If still available, about $40 on eBay from local seller.

interesting stuff.

It makes me wonder if the tune should be tweaked after the intercooler upgrade?

Any chance you can provide an update after remapping to allow for the larger intercooler? I assume that you won't leave it in the slightly detuned state (which is probably helping reduce the fuel consumption).

I certainly think it should, especially as the intercooler is probably the most difficult modification to implement. But I see it as having the most potential for performance improvement apart from the remap itself.

And I really have to wonder how much improvement there would have been vs stock if the car had been remapped and no other mods done. I suspect it wouldn't be much worse than what was achieved in Stage 4.

I am not intending to do any further work on engine performance.

To keep this thread up to date...



Narva 225 HID lights



New VW radio (does anyone know what I need to do to make it integrate with dash and turn on and off with key?)



Scan Gauge - brilliantly easy and effective and cheap



Whiteline rear anti roll bar - massive difference and all positive



Pirelli P7 tyres - suprisingly cheap and at least as good as the Michelins I bought with the wheels

Development of rear roof extension...using corflute mock-ups. Intention is decreased drag.



1 - attached flow from roof
2 - attached flow on roof extension
3 - separated flow



Different design with side attached flow



Comparison of wake areas with and without angled roof extension



Apparently successful design to be made from something other than corflute!

I like your mods, nothing over done... the way it should be.

You'd need the bigger intercooler to make up for the spotties!

Standard grille behind the spotlights is almost completely closed - ie it's a dummy.
