If so, was it worth it?

Walnut blasting seems to be the method everyone recommends - I've been looking to get mine done but can't find anyone local in Leicester who does it.

I believe the general consensus is it's not worth it.x2

I believe R-tech offer a similar service.

I didn't think r tech offered this service - will give them a shout

What do they charge for walnut blasting? I didn't ask last time I was there

Wonder if they've ever done a before and after dyno run?
Cleaned valves won't give you any more peak hp. At best you can expect slightly better cold starting and perhaps a slight improvement in off boost responsiveness.
Carboned up valves remind me of skidded pants. Not pleasant to the eye and whilst the skids don't affect anything, you just know they are there and want them gone.

Whilst strapped on a dyno, with a before and after run
Without being moved the whole time
There was an increase of around 20bhp with a print out

The old n'asp V8 S5, or the more recent turbo one?
You will defo get gains on n'asp engines as they ingest a fixed amount of air. And it's got 8 sets of valves clogging up, which when summed together is a lot more of a restriction compared to 4 sets of valves on a 4 pot turbo engine.
It's getting on for a £400 job on the TFSI, which is too much money for such a tiny gain.
If someone did some MAF logging at idle, part throttle and WOT and found an increase in air flow being pulled in under all those conditions, I'd probably do it, but if the engine runs smoothly and is quick, I'd leave it personally.

I'm not sure where you got £400.00 from to clean the inlets. Most places charge around £150.00 to do the inlet cleaning, Rtech are offering to have your injector seals changed as well as flow tested, I believe that is where the £300+ figure is coming fromim yet to hear of a company offering walnut blasting for £150
R-Tech are now offering walnut blasting service and will be carrying out other mechanical soon as their new unit is up and running or have already started the mechanical

Sure we're comparing like for like?
Ie not comparing terraclean or some such similar chemical process (imho a waste of time/money for these cars) v walnut blast or mechanical cleaning?

I think runner flap delete may even cause slightly lumpy cold start/idle. So I'm told by a reliable source with firsthand experience.Wonder if they've ever done a before and after dyno run?

If everything is kept clean I personally don't think it's necessary, just my opinion of course. :laugh:

I was going by the £360 that AKS charge, which is 'getting on for £400' in my book, especially when you factor in the petrol getting there and back, plus any other little bits and pieces that might need doing whilst they're in there.

That does seem to be the word on the street! I can understand why. Loads of fuel being chucked in so the atomization is poor, so the flaps do the 'crimping the end of a garden hose' thing to accelerate the air to introduce swirl. Neat trick.
They also work when hot to improve low end torque, so that probably suffers too, especially on laggy KO4 engines.

Anything more than idle or cruising and they are open/non-functional and nothing but a restriction.
Post by: pudding on March 09, 2017, 01:55:16 pm
Not much of a restriction though, in comparison to the other restrictions dotted around the engine. Intercooler, turbo scroll, port divider plates, etc etc. Niki said the flaps cause no 'restriction' issues unless pushing be 380hp.

If that's the S5 that was "engine carbon cleaned" at Surrey rolling road, that'll be the "Italian tuning" effect of revving the car and getting the upstream parts of the exhaust nice and hot during the process that resulted in the extra power. There is no cleaning going on at the inlet valves.

There's something I read somewhere, probably in the handbook, that strongly suggests that regularly driving at a higher rpm to build cylinder temps up and EGT's is a good thing to for the TFSI engines. You can use these cars without abusing them, treating them too conservatively isn't good for them.
The inlet system will always be flawed but add into the mix short journeys, an engine oil that might not be as good as it could be, cheap/low octane fuel, driven to mildly and extended servicing the outlook will be much worse I'm sure.
