MRC vs. Pippyrips' B7 RS4
Gentlemen,
I change my oils at every 5k miles and use shell v-power exclusively. However at 35k i felt the car sluggish and had lost its spunk.I was aware of this carbon buildup problem and it might be a factor to the felt power loss so I talked to my service mgr at the 35k service. He told me that they had at 2.0tfsi that came in all gunked up. They needed to run the product below through the system twice but *they* did see great results. I ran it through my RS once and the car felt a little more responsive but might have needed to be run one more time for better results. Next time I am up the for an oil change, I will make them start by running the product through the system twice then change oils, oil filter and fuel filter. I am hoping this might be helpful to us all as I hate to see audi dragging their feet on our 75k cars.

What I saw the tech do was use inject a flush apparatus with part 208 and part 210 and ran it through the engine for 20 minutes.
Anybody else use this product? I didn't see a big difference but it was noticeably better.

Intake Build-Up
Not wishing to dampen people's hopes, but having had my manifold off twice now, I have a fair idea of the scale of the problem and I cannot see how these types of products can possibly remove the depth of fouling that we are seeing on our inlet valves.
I have sprayed on an Air Intake Cleaner product - www.forteuk.co.uk - neat whilst trying to clean the valves and it does virtually nothing unless agitated with something and even then it doesn't dissolve the gummy and hardened deposits. Are the chemicals designed to work better in a working engine? I'm no chemist but it seems unlikely.

Re: Intake Build-Up
I would agree, none of these spray products are recommended by anyone inside Audi or by any of the people who independently modify and tune Audis that I have spoken to. The general consensus is that the carbonisation will need physical scrubing to get rid. Solvent based products at best may take surface deposits on the main carbon build up or indeed smooth the surface of the carbon build up much like applying a sealant to paint.caldy wrote:Not wishing to dampen people's hopes, but having had my manifold off twice now, I have a fair idea of the scale of the problem and I cannot see how these types of products can possibly remove the depth of fouling that we are seeing on our inlet valves.

RE: Re: Intake Build-Up
Agree with Caldy, it took MRC 8-9 hours of intensive manual labour to clean up my inlet. I honestly don't think these sprays will do anything other than maybe limit buildup once it has been cleaned up properly by hand.
Rob, logic would agree with you, but there are about 4 companies with products ....
I can't see Wynn's selling something that does not do what they say ..... obviously there is a counter argument here.
Let's wait and see what the dyno test brings.
The only other way is to use them on a dirty car a few times and then open it up.

RS4 Avant - Sold Aug 2009
i think most people believe the wynns gear is more of a help prevent than a cure for a already janked up inlet. that is why i thought it would be more beneficial for rob to try the wynns gear after he had his cleaned to see if it did prevent this over the 1500 miles.... we all probably know what it is going to look like seeing caldys pics of a 3k engine.P_G wrote:I don't think it is a case of saying they do nothing, more their actions are limited and not a patch on good old manual elbow grease.

Went out in Rob's car the other day and he asked me if I could put down a few comments regarding the upgrades.
I have a B7RS4 myself with a non res non valve miltek exhaust and chip done by APS - so I have a few tweeks and a good benchmark to give a view on his.
So, I can say with sincerity, it is substantially improved. It feels much tighter, more reponsive and more powerful. The way I would describe it is as if it has lost 300kg and ironed out the flat spot at 5000rpm.
The exhaust is fantastic and suprisingly quieter than mine in the cabin. God knows why because it is savage if you are outside the car.
Is it worth doing? Cant answer that one. Generally there is little point in major upgrades on any car as the money spent is not cost effective, but I have to say it has made a big difference to his motor and will be something I will discuss with him at more length next time I see him in relation to my motor.
