Its one of them ibiza cupra diesel thingys that i like. Been reading about them on the cupra forums and a few owners have chipped them to 200+bhp and 331lb/ft torque without any other mods and its possible to get 230bhp but will be very unreliable.
Also im guessing eddes tha man to ask so if you stick an airfilter on a diesel will it sound the same as if it was on a petrol as logical thinking surgests it does? any other good mods for diesels i know you can stick a dump vlave on but not sure if id bother.
Dump valve on a diesels wont work as diesels as they do on petrols as they dont have throttle plates which petrols do to need dump valves. So there is no hp or responsivness gains. Diesels can sound like they have dump valves particularly the 150 VAG engine but its the EGR valve suffing exhaust air back into the engine to keep emmisions down.
As for an aifilter on one well it shoul sound different but diesels dont work at the same RPM or operate at all like a petrol so the sound will be different.
Id be careful of pushing more than 280lb torque though the box and wouldd get them o remap to keep it below 300lb as the box isnt designed to take it.
The gearbox is officially rated as 300lb max. The clutch will also slip at around this figure but it depends. The box has proved to take well over this figure some cars are pushing 400lb+ throught it but Id keep the gearbox manurfactures figures (getrag) when remapping to heart they know the box better than anyone. If you want to push it its up to you the box in the cooper S is a getrag one and offically rated as 154lb torque but some of the tunners can push over 250 without problems.
I take it the 200hp + chiped ones are the 2.0 16V? the 1.9 130 wont get 200hp with just a chip.
Have you looked at the other VAG range the Skoda VRS has the 130 engine chippable to 180 or so hp and you can get more (just costs more) but its only group 7 insurance an 11~12k to buy new I think.
