Count me in please  

[Pat]

Put me down for some and I'll pass them on to my tuners

Anyone know about highly upgraded drive shafts an cv joints ? Race teams won't pass on any such info

[A18KNY]

Im a yes man nor a maybe :-)

[MacD]

Cant see how it could ,

 

Hopefully if they are changed then you wont need a warranty claim in the first place.....

 

Prevention being better than cure 

 

 

 

Just playing devils advocate but I'd wait until you find out why Fletch's car snapped the bolts before you guys order. 

 

Was it because something else seized or was it simply the sudden impact of power thats snapped them?

 

Until you know this you could indeed end up with a car that doesn't shear bolts IF something seized and could cause a big accident.

 

By all means do a group buy and get names on a list but personally i'd be waiting a proper diagnosis rather than jump on the band wagon.

 

Up to you lot though. 

[mrAudi]

I'll have to agree with McD as they may be designed as " sheer bolts" as a set of bolts are a lot cheaper than a transfer box & prop shaft

[MikeYoung]

Ttrs snap the bots, it's common...I would replace them guys.

[Pat]

I can't believe how many faults this model of car has
Cv joints
Prop shafts
Brake issues
Various recalls
Was this just a test the water thrown together car using a good engine but weak components from smaller less powerful cars and an old dashboard ??
I'm begining to think another Beemer, focus RS or Sumat Japanese might have made a better project

[RS3lover]

I agree, if the bolts are changed for stronger items and the bolts aren't 100% the cause then all you are doing is sending that 'shock' loading further down the line, the pictures of that holed transfer box speak for themselves.

 

Don't forget it could be designed to do this, if anything the central locating pin could do with strengthening to stop the prop bouncing around.

[RS3lover]

Don't forget this wasn't a standard car.....the remap could easily take it past the safety tolerance, that is a huge amount of torque to send out all at once.

Take my advice if its mapped don't launch it !

[Mr_Freeze]

I don't believe it's a one time thing, more a culmination of several launches slowly stretching and stressing the bolts, I saw pictures a while ago of one where the bolts had started to stretch and twist, I suspect if we start changing them out we will see more like that,

Can one of you who knows the chaps at Awesome ask them if they do a kit, I would prefer to buy from them than an unknown in the States?

[MikeYoung]

I don't agree with RS3lover at all.... How many boxes have gone? On this and the ttrs.... Exactly..... How many bolts...

Do we know who's car the holed transfer box was from?  Only reason I ask is it could have been from a 600bhp+ TTRS for all we know.

[Viraje]

I'd be amazed if the engineers at Audi 'designed' the bolts to sheer at a specific force to prevent further damage to the other components. Car engineers, (and German engineers in particular), don't think like that. If this was a known issue, they would have engineered the problem away. They certainly wouldn't have chosen a solution that allows the propshaft to destroy anything in reach.

 

Bare in mind that Fletch's car is running near on 400bhp. The standard drivetrain hasn't been designed to reliably take this much torque, and there is always going to be one component that's weaker than the others. 

 

Like any car, the standard figure of 335bhp was decided on by Audi, not because that's all the engine will produce, but because that's how much £40k reliably buys you when you're pricing up the car for your intended market. Audi could easily have provided a standard map that gives stage 1 figures, but once you uprate everything else to cope, that changes everything about the car, (like the price, fuel efficiency, tax bracket, insurance cost, knock-on effect to the rest of the Audi range, how likely anyone is to pay what is now £50k for a hatchback, etc etc). It may make it a better car, but that's pretty academic if nobody buys it.

 

The TTRS with the exploded diff was running stage 2, so a massive hike in torque over standard. I'm not aware of anyone else in any state of tune that has had the same problem, so to suggest that this will happen if you uprate the propshaft bolts, is kind of like suggesting that you'll also break your aircon, because the aircon on his TTRS also had a fault.

The trick is to think if bog standard cars snap the bolts.... They are worth changing.

And to have a 3 year warranty.

Standard car shears/breaks its propshaft Audi fix under warranty

Re-mapped car Audi might tell you no chance we ain't paying, everyone knows the risks and Audi ain't stupid

You pay the money you take the chance...

If the RS 3 in standard form isn't enough, buy something better.

Guys I'm late to the party here interested in the bolts but what happened to Fletches car??

I have had many vibration issues since replacing the factory front tyres resulting in countless wheel re-balances and a new set of wheels. Have also recently had O/S front CV joint driveshaft and transmission unit failure and I still have a 'clicking' sound coming from the front of the car which aparantly indicates CV joint failure!

Sorry to hear about your problems buddy, hopefully Audi are treating you right?

Regarding Fletch's car - So far from what I've read on his thread here, I (and I say I because it's my understanding) read it that the diagnosis was put down to the bolts that attach the prop shaft to the rear diff twisted/snapped/sheered off when he used LC.  Fletch's car is mapped from what I understand but there is apparently stories of stock RS3/TTRS's doing the same.

[Pat]

I've never been a sit on the fence type of person but in this case I am as I do believe that the car should be stronger than it's showing on drive train components and that it appears the power has been built around the components....but I also agree that the cost of the car bore this in mind as stated, something I'd not thought of in my crazy project choice.....my original choice was to build a 1000bhp V10 RS6 that realistically required no alteration to any existing components other than for choice
This car has been engineered to handle big power and components and I get that now......
I do still find it hard to believe that the components are on and past their limit on the RS3 in std and mild mapped format....not usually Audis way

I do think they've worked backwards from the components reliability limits and then calculated the max power

Anyway I'm off to a meeting this afternoon at PSI tuning and we gonna talk about Motorsport components used by race teams or drop Viagra into the gearbox and diffs to stiffen everything up !!

[mrAudi]

I tried the sitting on the fence game.......all I got was splinters
