Octavia 1.9 PD TDi 300bhp Clutch

[944]

Hi all

Just had a remap done by Celtic Tuning down here in Cornwall, very happy but the next stage of tune is to fit a rather tasty Garratt Hybrid Turbo and another remap by Celtic and we should be hitting 250-270 bhp so I need some unbiased advice on a clutch upgrade; it should be capable of handling 300 bhp and 350+ of torque, from my understanding the torque is what rips every thing apart?

The car is a 2008 Octavia 1.9 PD TDi

My driving style is, brisk but I drive within the band of max torque not higher revs where you are calling on your higher bhp, so I keep the revs between 1800 and 3500, at 4000 rpm the engine will be producing max bhp of around 250-270.

Any help would be great

Thanxs in anticipation,

Sallyanne

Are you going to upgrade the transmission and half-shafts as well - otherwise you'll end up breaking on or the other with the amount of torque you're going to be putting through it.

[Spudler]

I guessing you've upgraded the brakes already.

Worth looking/asking on here?... http://briskoda.net/

You can double the power with just a bigger turbo and a remap
Wont it just wreck the internals of the engine fairly soon?

[zakelwe]

Rather than spend money now just in case I would suggest see how it goes and then if it grenades you can upgrade. You are balancing the inconvenience of being left with a non drivable car against throwing money away getting rid of a good clutch. So I would say how much would the pain be compared to getting good value and experience. You will know this trade off compared to my suggestion.

Good luck!

Oooooh so many replies so fast, thanxs.

The whole car is a running fun project, so breaks, suspension, and transmission, basically the works is being carried out. Including the interior being reworked by Recaro seats, thanxs to Capital seating, the Colin Rouse in Cornwall will create a new leather interior.

With the clutch I didn't know if I should by say buy a clutch just to cope with say 250bhp, and then on the last leg of the tune get the clutch that will run with real high bhp and torque numbers.

Of course at some point I will have to get someone to lift the engine out to rebuild a stronger bottom end, I think this should happen when we pass the 270bhp point, again advice on this one would be great.

Thanxs

Andy what a star you are you have hit the nail on the head, I use the car daily ish however I do have my old 944 but this is having some much needed tlc so I can't use that, so trying to create an order of work with minimal down time and waste is important.

I think many people who use there car as a running project have this problem, so any advice on this area grabs my attention big time....It sounds like you have done something similar?

Thanxs

This problem is proving to be a little troublesome; I am fitting a set of 8.5x18 ADR alloys from L.A but due to an unusual off set I need to extend the front wheel arches by 30mm, the rear as well just so they match but the alloys fit no problem with 225R45’s. Can you buy whole new wings, with a 30mm increased flare? Or do I have to just fit say a Milotec wheel arch extension kit?

Again any help, or companies that could create a pair of bespoke wings would be very cool, expensive but cool, well worth saving for.

Thanxs

Sallyanne

Whole new wings will have to be custom fabricated (£££££) so go for the milotec kit.

To be honest the nearest I have ever done, mechanically wise, to a car is to open the bonnet and drop to my knees and cry into the windscreen washer bottle because being a northerer I am too tight fisted to top it up from something blue or pink from Halfords.

However I still think, given your backup I would see how it goes.

Andy

[944]

Thanxs Andy that made me laugh!!

My Dad started me off under lorries, met a guy later in life who is a real petrol head and at the age of the big bad 4 o I started my childhood again with cars and love it!

The image of you crying into your washer bottle leaves me in stitches...hahahaha

Thanxs for be so honest, stay cool,

Sallyanne

For the original question, depending on how the torque is delivered, you may get away with an uprated sachs item.

If that slips you'll be looking at probably getting a single mass fly wheel effort.

Internals and driveshafts should be fine with the power your running.
Briskoda as mentioned is worth a visit.

Edit: id be very supprised if Celtic managed to get 270bhp out of a Garrett Hybrid.

The Bhp claim and target actually came from a very helpful man at Turbo Technics or Turbo Dynamics I think, I do know that Celtic are in talks on the turbo subject with Garratt and I have a meeting in January at Celtic Tuning to discuss and finalize this stage of the work.

A point worth mentioning is that this project car will be the subject of a published article, so any help or advice will be recognised appropriately. And I must say so many online "tuning Companies" have been amazingly helpful and supportive. Sadly my first two posts where removed because someone thought that I was advertising, that's a NO I'm a petrol bed chic who wants to have a car that I love and have created.

I am doing all this for the fun factor and hopefully show people what can be done with just a good old family hatch if you wish. As soon as its all done I will drive the car for a few weeks or months then put it up for grabs as I have my eye set on going crazy with an Alfa Brera.

Thanxs again

Do Celtic have any history of remapping hybrid turbos?

I've been out of the diesel Tuning area for a good few years, so things may have developed further. From a 1.9 you were looking at the injectors being maxed out at around 240bhp ish, so you'll need extra fueling to make 250+, this can be in the form of larger injectors (expensive need to be mapped properly or it will be a smokey beast), propane, nos or both.

Sounds like a fun project though.

I'll keep an eye on it.

Good way to loose some serious dosh, Im having trouble putting 170brake on the front wheels I wonder how it will cope with 250+.

I thought about a remap and de-dpf which will give me 220brake for a bit over a £1000 but all that torque nd power dont think it will make it better drive

As I have a set 8.5x18's going on, big discs and four pot callipers are no problem and a sensible cost compared to six pot callipers which have crazy expensive pads. As the visual side of things change with the car I will upload detailed pics, engine re-map side will be dealt with by posting the dyno run graphs.

Dyno graphs at each stage will clearly show a £ to bhp/torque value, that way if anyone wants upgrade things they will be able to make a good judgement call as every ones budget is different.

As regards to the comment; "I call bullst, too." If the project is of no interest just say as I have no need to post if you think its a waste of time or "Bu..sh.t.

It's not of no interest. I just think it's pointless, as a 300hp PD isn't going to be practicle in either driveability or reliability terms.

A 140hp 2.0TDI PD remapped to 170hp is difficult enough to drive due to torque steer and keeping grip (it overpowered the grip of 225 wide Toyo T1R on a dry road in 3rd, and that engine was in a 1650kg Lancer). What are you going for? 255 wide semi-slicks and driveshafts out of a DAF?
