Im running Tarox F2000 grooved discs. Currently have the Tarox Corsa pad which is identical to the Ferodo DS2500( pad shape is identical to Fiat Coupe 20V Turbo with brembos).

The DS2500 is basically a fast road, light track pad. Its a very good pad for just that. Mine started to fade towards the end of 6-8 laps at silverstone, although i was being pretty heavy on the brakes testing out their performance as actually haveing some braking performance on this car was a novelty. DS2500s when hot can spit pad residue over the wheels from past experience. Great pad and a nice improvment over stock compounds, especially when there is some heat in the brakes.

The DS3000 is the next pad up and is a fast fast road, heavy track pad. Ive not used these before, however speaking to guys who have used both, they say the cold bite is the same as the DS2500 but bite when hot is much stronger, and they wont fade at all. I' ve also been told they dont eat through your discs like Pagid RS29s doeither which is good news.

I thought the old p1 subarus came out of the factory with ds3000 pads but had to be recalled and replaced with ds2500 as the 3s caused bady work and paint damage due to hot bits in the dust.

Sure it was said on here ages and ages ago

the DS2500s do, so i wouldnt be surprised if the DS3000 do as well. Its a problem with the higher spec pads when stopping power becomes higher up the priorities.

Love those calipers :)

They DO look fabulous and as far as I remeber the whole brake upgrade is not that expensive either.

No idea, i got them cheap off of hurdy lol.

Oh, maybe that's why remeber it as being afforable :D - not getting younger here ...

I think as aftermarket kits go they are much cheaper than the likes of AP and Brembo, but i guess there isnt the same pedigree with Tarox though. Brakes are the best mod i think though. I think even the 312mm upgrade or even R32 twinpots will be an awesome mod.

edit

It would be the exact same as this kit. Same part numbers, hubs etc

£1200 incl VAT http://www.dcperform...t/kmvw0986.html but would this kit be £700+ better than an R32 323mm twin pot setup....probably not IMO.

You seem to have neglected to accept the fact that skoda had to produce revised pistons/rings for this engine due to problems with the older ones. They have even gone as far as to change that much on this engine that it now has a completely new engine code.

Im not blaming the manufacturer, its a combination of many things, as i have mentioned many times, but the root of the problem starts is IMO poor pistons from the factory. The question is would this have happened on the CTHE engine?

Not due to ring lands cracking though!

What do you class as "not that expensive"?

Having the price provided by Sy now Tarox kit certainly doesn't qualify :D

  • Author

£1100 for a BBK is reasonable, and its certainly not expensive as BBKs go, most are closer to £2k. Had a look and you can get brembo 4 pots 323mm brake kits for the same money as the tarox kit and Id definitely go for the brembo over tarox if i was to buy new.

DaveB had a 4 pot porsche kit with 330mm discs for this car for a bargain price back along. That would have been pretty good id imagine.

Great news :love: I have the car back and its quick, handles very very well and feels lovely and taut. Havent pushed it too hard because the brakes have minimal material left, but overall it seems like a great package now. Car has stock, 95, 98 and 98+ meth map installed. 98+ Meth map is bloody quick.

Bad news :wall: There is still a high boost misfire, as a result, were still not even close to pushing the turbo anywhere near its potential. All plug, coilpack, fueling and software solutions have been explored and haven't made a difference. The next route is to try the valve springs, to see if this is a result of weak springs. This was a known issue/cure for the 2.0TFSI and 2.0TSI. Hopefully this works and we'll be running a peach of a setup very soon.

Annoying news. :@ New front pads required pretty very soon, which Alex being the good egg that he is, has sourced for me.

Its been in some pretty heavy company though

Sounds good mate, glad your pleased! Enjoy it for a bit now!

On a separate note have you been out in the TT-RS top left of the pic OMFG is that thing fast an I've driven their golf but Keith took me for a spin in that and I've never experienced anything like it! Your peripheral vision goes fuzzy your moving that quick :rofl: :rofl:

Just for Jabozuma

This is what the failed piston (No1 from the left) looked like when it came out

Im very lucky they noticed the loss of power when it did, another run on the dyno could have dislodged that piece of piston and trashed the bore and potentially the engine. The other pistons look perfect and have no mars, cracks or issues at all.

The good news is the car not only has very good compression now, but the cylinders compression are also within 1% of each other. From what i gather, OEM tolerances are within 10% is acceptable :o

@jobazuma, I think we now know why i experience torque steer more than most.

When test driving it the other niht with Keith@APR the "torque Steer" was pretty savage and really pulled the car to the side, but we think it might be the XDS settings.

I have mine set to the most aggressive setting. we think the problem lies with the fact the XDS is calibrated to apply braking power to the standard size discs/calipers, however my car has much more powerful brakes. Im going to experiment with the car using different XDS settings at some point and see if the "torque steer" is in fact the XDS and my brakes not working together correctly

One of my mates had some footage of me at silverstone so i thought id post it up.

http://www.youtube.com/watch?feature=player_embedded&v=lP4tHBrx6kM

This was using the older BETA test map to see how it performed, it was suffering a high rpm misfire so gear changes were being done manually at about 5.5k rather than 6.5k. Chassis mods were springs and poly bushes only.

Id love to go and try it again with my new completed setup.

That surprises me.

Open road, yes.

But big heavier car that's FWD in the twisties, like a typical UK back road blast?

You'd be greatly surprised how awesome Mk2 Octavia's handle, and indeed go. Not much can keep up with me day to day...

Day to day I'm sure, power to weight it's probbaly in the top few percent on the roads.

But on track I favour a smaller lighter car.

On the How Fast day (admittedly it was a bit damp) but a mk2 VRS Fabia beat us both, with 100+ less bhp than your Octy it was several seconds per lap quicker.

I also noticed at the 2nd How Fast day how much quicker the Yeti could get the power down exiting the corners compared to the FWD Octavias.

Yes, a tuned Octy is good.

But it's still a big heavy car with the drive going to the wrong end for tighter corners and damp conditions.

As I said, on roads that are a bit more open I'm sure it absolutely flies! (natural tuned Octy hunting ground IMO)

or come to Mallory park tomorrow..... :devil:

Ive mentioned this before but also consider this

http://goapr.com.au/...mm-june2011.pdf

Compare the Stage 2 APR demo Polo GTI 1.4TSIwith only 221hp with the Stage 3 APR Demo Mk6 Golf GTI 2.0TSI with 380hp.

Same engine/chassis as the Fabia so is comparable.

Same driver

Same tyres (albeit different sizes)

Same track

Same day

Both on H&R coilovers

Both on Alcon Big brake kits

etc

etc

The Golf has an extra 75Hp/ton power to weight ratio but with all that extra power (160Hp) it only gains 1 second of laptime over the grossly under powered polo. Id wager the place where this second is made is on the main straight because its an extra 9mph faster and the only times where the Golf beats the Polo's speeds through the corner it is by the tiniest of margins of less than 0.5km/h. It does show that all that power is pointless on a tight track and it only benefits you on tracks with long straights, but thats boring anyway because its easy to drive in a straightline.

IMO, my car with all its current mods would now annihilate my Octavia on the track. Before i added the ARBs i would have lent towards my Octavia (with ALL its modifications) being the better car, but now, not a chance. Thats bearing in mind with only the 98 ron map turned on with my car there is only about 15-20hp/ton difference between my car and a stage 3 k04 Octavia so substantially closer than the 75hp/ton difference in the above group test which only managed that 1 second faster lap. Ive not dyno'd my car with the water meth running yet with the Meth map but ithas 10 degrees of ignition advance and is MUCH faster than the 98 ron map, and i mean it MUCH faster.

Anyway

Just back from Mallory Park, not a bad day, but not the best either tbh :think:

I thought last year at Mallory was wet but this year it was much worse. It rained constantly all day and the track pretty much had 3 m wide streams of water midway around Gerrards, in the braking zones at the end of the Stebbe straight & Shaws hairpin and another pool of water exiting the devils elbow where the track goes off camber :whew:

LOADS of red flags from cars, (one in particular, who repeatedly tried over taking everyone on the outside of Gerrards :wall: )

I had a few brown pants moments with the standing water but considering i was on worn federal 595RSR semi slicks i was mighty impressed with the car, it was able to put the power down nicely and could still be thrown about almost as much as in the dry. I took a pair of alloys with new federals fitted to put on the rear if it got to tail happy in the rain, but never needed them in the end.

I started the day on the 98 ron (250hp) map but found it to aggressive low down for the conditions, so i swapped to the 95 ron (240Hp) map which was much easier to get traction with. Performance wise i was just about able to hang on to a Focus RS Mountune for a few laps which I was pretty happy with especially considering he was on summer tyres and I was on semi slicks and that was on the 95 ron map :love:

Sacked it early though after only about 70 laps. Bad guts and a massive headache all day, so after people started going off more frequently, and with loads of mud from the "offs" on the track i just packed up and went home.

Plus with about 70 laps combined with the 30 mile return trip up the motorway returned a nice 22mpg :rock:

And im banning my brother from driving my car on track again. He got overtaken by a Citreon C2 VTR :ashamed: :wall:

Dont think ill bother with Mallory Park again though, its to short and starts to become boring after a while. Never had that feeling on other tracks before.

For those interested in the Anti roll bars.... DO IT. The handling on the car is phenomenal with my current setup. I genuinely dont think id gain much if any by putting coilovers on the car, it would also ruin the daily ride as well.

oh and Mintex M1144 pads struggle after a few laps. Ill be replacing them for my next trackday when ever that is.

Still selling then? :)

I will do, but the question is when....

Yes, that's always the case isn't it?

Once the new toy is done I can't see me getting the chance to use the yellow thing very often. Similar situation, it'll go, but when...

Is 250bhp what will be running at now, or will there be more power upgrades to come on the Fab?

  • Author

250Hp is the 98 ron map. I can use the Methonal map as well if i want. Not sure of the power on that one tbh, it hasnt been dyno'd yet but i know it runs an extra 10 degrees timing which should make a pretty decent improvment in Hp. It certainly feels alot faster.

In all honesty, im happy with the straightine performance of the car, its more than enough to keep up with much more exotic machinery. Im trying to remain conscious that too much power will just ruin the drivability of the car.

Next ugrades are

Engine mounts ( yoyu can hear/feel the engine/DSG clunk on downshifts when braking heavily on track)

Ferrodo DS3000 or Pagid RS29 track pads.

The a LSD when/if it becomes available before i sell the car.

While the key to a Fabia size/weight car is manouverability, I'd still like to see what this can do at the quarter mile one day.

It's clearly the most powerful mkII out there and would be interesting to see how it compares to the more highly tuned mkIs.

Even at 250bhp it's got more per tonne, with the positive of the rapid gear changes and the negative of less torque it may be pretty close.

BTW, nice to see it being used as it should be too. :)

I reckon with 10 degrees ignition advance with the water meth (60:40 Meth:water mix) its got a 270hp in it. Certainly feels MUCH faster than the 98 ron 250Hp map.

I think without me in it the daily running spec (98 Ron map) is about 215-220Hp/ton. If i was to run the Meth map and it is giving 270Hp i think it'll be closer to 230Hp/ton which is plenty quick enough. I'm at the limits of traction at the moment i think. Power is nothing without control, so its pointless for me to aim higher right now. Hence why i started using the 95 Ron (240hp) map yesterday so I had more traction in the wet.

What power to weight ratios are the modified Mk1s managing?

In all honesty, i cant see a Mk1 challenging it on a 1/4 mile run. Id be confident of a 13.5 in mine in good conditions maybe faster if i can nail the launch. A rolling start might be more interesting though

I think without me in it the daily running spec (98 Ron map) is about 215-220Hp/ton

It won't be very quick without you in it though, Sy, however many it's got :)
