A couple of questions for the modders:-

Someone on seatcupra.net seems to think a FMIC is essential when the car is remapped. How true is that? How much does one cost? Is not more effective simply to use an intercooler spray, while would allow one to cool the turbo even while say, sitting in a traffic jam?

Secondly, about the brakes, many people get the 312mm conversion with uprated pads. However, might it not be just as effective to get uprated pads on the standard discs at the front and rear... would it not be more balanced like that? To me, putting more powerful brakes up front and not doing anything about the rears is in theory, going to make the nose diving problem even worse...

right with the fmic it would be nice to have one but your looking 800 notes but imho its not esential to have one but you would get more power from it as it would cool better than the oem unit.

the brakes. there is no replacement for surface area when it comes to brakes. the more you have the better you stop fact also aided by better friction compounds but they can only do so much .

yes your right it be nice to do something to the backs too but its really not needed or really possible if you cant find pads to fit there isnt much you can do :(

Silly Q now - are vRS standard rear brakes bigger than TDI/etc standard rear brakes?

I would say its adviseable but not essential to have a better i/c. so if you do get remapped, dont complain in summer when your car goes slow and smokes alot :P

as for brakes, i think the issue is the std calipers are actually a poor design.. and offer very little feedback.. presume they were made on the cheap to save putting the normal 288/312 calipers on.

bigger brakes will not make the nosediving worse, the electronic trickery balances brake distribution.. so after a few high speed stops, its very stable.. but keep an eye on the rear pads

The answers to both questions are out there.......and in here many times.

But then whats the fun in searching when we can discuss them again

1. Yes the intercooler spray will give a similar cooling effect as a larger intercooler, but its not going ot work as the time (unless you have a couple of hundred gallons of water on board) where as a larger intercooler is a permanent fixture. And yes during the summer months an uprated inctercooler will certainly help, the lower the inlet temps the more power can be produced simple as.

2. A larger discs give greater leverage so will give more braking effect. Plus the area of the pad is larger on the 312mm brakes compared to the 288mm set up, this will also increase perfomance. As for balance the vehicles ABS system determines what braking force is needed where depending on such variables as grip and loading of vehicle and will still work in the same way as the standard brakes do. The piston size has stayed the same int he caliper so the master cylinder and the ABS block are not effected by the larger discs, its just you tend to use less force to slow down, or use the same force just brake later as the case quite often is.

Thanks guys.

One more question about the Turbo. If you get a proper remap then it does increase the boost, does it not? If so, then what about digital tuning boxes, which dont increase boost, only fuelling yes? So, am I correct to assume that the Turbo temperatures would be less of an issue with a tuning box?

PS. I dont want a discussion here about how remaps are better overall - I know this...

Ross, on point 2, for the Octy it's the same pad for 312 or 288. I know as I've fitted them to my old RS and to my "SDI"

So the 312mm setup which we refer to only available for the front?

So you get the front callipers/carriers with Octavia vRS 312mm discs and DS 2500 pads or similar, and on the rear just get DS 2500 pads?

I always thought it was 312mm setup all round .

Chris.

nah you wouldnt want the same size front and back it wouldnt work too well

So it's 312mm brakes/pads with the new callipers/carriers at the front and then the normal brakes at the rear then with just new pads?

well if you want to replace the pads at the back then yes

So how much difference would replacing the pads at the back make?

Doh! I always thought the 312mm setup was all round, didnt realise it was just for the front! I think I would change the rear pads though, just to give a little extra bite.

What size are the rear brakes, 288mm?

One more question about the Turbo. If you get a proper remap then it does increase the boost, does it not?

yes mines running at 1.6 (I think) but I dont know the answer to the rest of your question

the fronts are 288 rears i think are about 250 but im most prob wrong

I thought the rears were 232 mm

Ross, on point 2, for the Octy it's the same pad for 312 or 288. I know as I've fitted them to my old RS and to my "SDI"

The fabia/ibiza use a different caliper design on the 288mm setup. Thats why you need the calipers as well as carriers when upgrading to 312mm.

Seems daft how they did that. Surely it would have been cheaper to use the calipers that they already had rather than designing new ones for the Fabia / Ibiza. Especially ones which are supposedly markedly inferior.

Do Golf 4motion or Anniversary Callipers/Carriers fit the front?

So you get the front callipers/carriers with Octavia vRS 312mm discs and DS 2500 pads or similar, and on the rear just get DS 2500 pads?

I changed the front and rear pads to EBC Greenstuff, when I had my conversion, seems to be working very well...

...If that helps
