Although your car may be smooth and make heaps of power, I am pretty sure your car could benefit from a valve clean. Especially at 147,000km.

Are there any quantifiable (measured) improvements published? Why don't BMW suggest this? After all, I'm sure they'd charge 2 x the going rate if it was more than a placebo.

Cheers!

G'day,

TBH the job isn't difficult at all, just a bit fiddly, with most of the time taken up in disassembly and reassembly. The 1st port took about 25min to clean, the 6th about 5 mins... There are a few great DIY's on the net which I followed to the letter, with a good result.

I've only done the job once, about 6 months ago at 175k kms and the car is now a track car, so doesn't do many kms, especially at the moment as the engine is on the other side of the garage from the car...!

I can't remember where but I remember a dyno was done afterwards.

I too have seen a dyno that showed power increases after having it done. Most people report a much smoother idle as the most noticeable difference after having it done. Some people even describe the difference as being night and day. The idle on my car on cold starts is absolutely horrendous. It really struggles and there have been a handful of times when the car has actually stalled about 30 seconds after being started. Other people reported similar symptoms that were fixed or at least reduced by walnut blasting.

It is recommended by BMW North America that it be done every 30,000 miles. That's why I think it's strange that most Australian BMW dealerships don't even seem to know of the process and don't offer it.

EDIT:
Here's a dyno before/after. Remove the space in spool street.

Hmmmm.....those "after" power and torque numbers at the wheels exceed the factory figures at the flywheel. Something a bit weird happening there.

In the post they mention the car already had a tune already installed, so the numbers are going to be higher. BMW usually underquote their power figures anyway.

I have walnut blasted many cars you definitely feel a difference in idle smoothness. I have never done a walnut blast and the owner not noticing a difference. At 147k kms the inlet valves will be absolutely caked in carbon buildup. Smoother idle and more power in the mid to high rpms is noticeable.

Are there any recommendations for places in Brisbane that do this - without causing engine or cosmetic damage?

Had a chat to an employee at Perth 3MW today, apparently he was in the middle of a walnut blast as I rang! It was nice to speak with someone who actually knew what they were talking about. He said they charge $795 for the service.

So far I have been given the following quotes:

RAMP Auto Group - $880 (Soda Blasting)
BMTechnics - $695 (Walnut Blasting)
BMW (hire in a tech) - $800-$1000 (Walnut Blasting)
Perth 3MW - $795 (Walnut Blasting)

Still heard nothing from Galvsport....

Hi mate, sorry I just saw this thread I haven't been active with car forums for a long time now. Galvsport did mine and it was around $500-600 from memory. Best to give them a call again, alternatively send them a FB message or email. They get a lot of phone enquiries during the day and you must of contacted them during peak Racewars season.

For the record this was me.

I thought it was a bit expensive that I am charging $550 for walnut blast.
