Problems found after trip to MRC

[Steve_C]

whats your mileage ?

10hrs at c.£70 an hour is expensive for 40hp esp when the carbon will only come back

After how many miles will this problem happen again ?

Im curious to see what the estimates are here for the return on the Carbon RS4 killer!

It depends on how you drive it IMO.

As soon as you turn the ignition; it's a by product of FSI. To what degree and physical amount, who knows but it's not linear. Like said a lot is about how the car is driven / frequency / length of use, warm up proceedure, full use of rev range / Italian tune-up etc etc. Go and see how your car fares against DK's and in the meantime try seom Wynns DIP3 petrol addittive to see if it perks the engine up a bit. 10% gain in a 400bhp+ car weighing 1700+kg will probably not amount to much difference on the road as Pad125 and I found.

Will do thanks.

I should also say I am not knocking MRC's work and / or diagnosis. If you have the money to do the work and want to spend it then that's your perogative. The reality is there is not long term cure for this and it will return to some extent and with its return would be the perceived lack of power so it is whether you want tp pay for it to be regularly cleaned to keep it in peak condition for that few extra bhp.

My RS is taking a back seat on the daily commute for a more frugal model as of tomorrow so with it being stationary more often I may now take the time to have it opened up and see what the picture is on a 80+k mile RS4 than has never been cleaned for a comparison.

thinking of getting MRC to do this - so can you confirm the cost is £700, is this including or plus the dreaded 20% VAT?

Speak to Doug for the price, that was the figure mentioned to me I don't know if it varies on how bad it is.

Thanks for that, so anyone hot an idea on the optimum warm up steps & driving style to reduce the effects? I know none of this is tested, just curious on what everyone thinks.

I use mine as a daily driver and wait till its warm before giving it some beans. Do like to get it over the 5500k sweet spot, but with full care an attention!

Recon I need to get her on the dynos!

My own schedule is not to do anything over 3k rpm until it is up to 60 degrees C and nothing over 3.5krpm until up to full temp (94-97 degrees C). Then it's ready for full deployment.

I'm getting this done and said I thought the port & polish was a waste of time as it wasn't permanent.

I was told something like this.

'The polish and porting/modified intake is permanent - the clean is good for the car and the porting and modified intake manifold stops the build up being as bad'.

Expensive agreed but surely it can only do the car good?

Are you having the IM de-vaned so it runs in constant homogeneous operation?

I keep things below 4k and half throttle until until approx 90-95 degrees.....I will then give it the beans until the last couple of miles of the journey when I aim to get the oil temp back down below 100 degrees.

Incidentally, when should the 7k rpm limit go? I've seen mention of 60 degrees (per P_G above) but my temp seems to be more like 69-70 when the rev limiter goes.

[edge]

So nothing over 3.5/4k until the temp is in the 90s from what people are saying?

That sounds about right, think its good practice.

fyi MRC remap is set to 5K limit until warm up is achieved.

I'll find out.

Drove into work today, kept an eye on rev counts and drove as normal, so recon im good to go.

Plan is a trip to MRC this year, just need to figure out what exactly I want
