Walnut Blasting, My Experiences.

[Czar]

True- wonder how long a "Careful" driver could go before carbonisation gets a real probleM
But if you consider the post I have just contributed to the Terraclean thread- seems there is an opinion driving hard and fast keeps carbonisation at bay

Wheres Czar when you need him LOL

How can I help Chris ?

Scouring Wiki I would imagine

I don't read anything on Wiki.

Think he prob wrote half of Wiki :-)

I have never added anything to Wiki or indeed read for reference anything on Wiki.

I think plagiarised is the word you are after.

Everything I write is from my extensive 31 years of Motorsport knowledge, and not anyone else's, I have been writing on public forums, regarding the THP engine, since April 2009

My involvement with the THP engine is such, that I was the first to produce,working with my component contacts, aftermarket engine components:

Reworked cylinder head including all valvetrain components.

Updated fuel system, including a new 200bar HPFP (high pressure fuel pump) worked along side Bosch and Continental on that one.

Ceramic bearing turbo.

Tubular exhaust manifold.

Aluminium inlet manifold.

A full redesign of the reciprocating mass.

Reworked oil system, including the addition of a 6 stage dry sump oil system

Bespoke custom timing chain and slipper guides.

Oil filter relocation assembly with oil cooler too.

Cryogenic treatment of all the engine components, including the engine block.

If anyone wants serious high end engine components, they are available, but be warned, they are NOT cheap, they were designed for my personal BMW MINI project, and anyone wanting Big HP/Torque with a wallet to match.

Can you enlarge on the bespoke custom timing chains & slippers what car what engine where they designed for etc would an oil cooler help a thp engine?

Think it was the reference to a Terraclean agent who suggested driving a GDI engine powered vehicle hard, frequently, (And using premium fuel which we know) was the best way to keep carbonisation of inlet valves to a minimum.

My understanding was that the more aggresive the fuel burn, by heavy use of the throttle would not only cause more soot/oily smoke from the burn (Maybe when changing gears the moment the foot is off the throttle) and that the higher temperatures around would more easily solidify deposits to surfaces?

If that makes sense

And why isnt a "non-stick" coating developed, to cover the inlet valves and other surfaces needed, or other method, to tolerate the carbon as the by product of combustion of fossil fuels?

I had a timing chain and slipper guides made for my BMW MINI project, which shares the THP engine, the THP engine already has a thermal heat oil/water cooler fitted as standard, you will find it located on the front right hand side of the engine, underneath the exhaust/turbo manifold, cooling of the oil is a delicate issue, you can quite easily over cool the oil, and for regular street driving, it's not necessary or indeed a good idea.

I wrote about this very subject way back in 2009 the THP engine does indeed suffer from less oil suspended particles (carbon build up) the harder you drive them, my BMW MINI's are driven very very hard all the time, those who are lucky enough to be a passenger, are amazed why whilst urban driving, I never use any other gears, than 1st and 2nd, and run Soley on premium fuel, that said, I don't care about MPG, I also change my engine oil, filter and spark plugs on a very regular basis.

When a manufacturer designs and develops an engine, it is done to a very controlled set of regulations and budget, if a manufacturer was to have a free hand when designing and developing an engine, you would be looking at premium money and very intensive service costs.

I also change my engine oil, filter and spark plugs on a very regular basis.

And people knocked me for changing my oil and filter every 5000 miles and my plugs at 15k.

And people knocked me for changing my oil and filter every 5000 miles and my plugs at 15k.

If people really understood just how much heat cycling degrades engine oil and spark plugs, they wouldn't knock you or myself, I get ridiculed at track events, for the simple reason, that when I drive to the track, the first thing I do, is change my oil, filter and spark plugs, and before I drive home, I change them all again.

This may seem excessive, that said, you've gone to a track for one purpose only, to push your vehicle to either its limits or your limits, so correct prevention is far cheaper than a repair.

I see and talk to so many at track events, who tell me there is no need to do what I do, as their vehicle runs just fine on OEM oil, filter, spark plugs, discs and pads, and time after time, I see them either having to slow down due to brake inefficiency on track or indeed come off track altogether for a cooling down period, limp home with a possible breakdown on the way, or be recovered from just outside the track facility.

And I just spend a few extra £££ and a little time on preventative measures, and really enjoy my track days, with no fuss.

Have mine booked in with Jamie on the 6th of October let's see what mine looks like with 70+ k on the clock

[Jamie@SPTuning]

Yes, a look at a higher mileage one will be very interesting indeed.

I saw a guy removing his tailgate on his 306 at the FCS just to do a 1/4 run....crazy!!

a fresh bag of walnuts I suspect

[Markymark]

Well had my car done today thanks Jamie (sp tuning) was really bad,hopefully Jamie will put some pics on later for you all,will definitely be back to sp tuning for some more work in the near future,Jamie is a to notch bloke

[Toxic]

He's stuck them up on Facebook.

[Jamie@SPTuning]

Yes it was the worst I've come across to date.
In one of the pictures you could actually see where a large chunk of carbon had recently broke away and rattled it's way through the engine.

[Chris_Blue]

70,000 miles ? Hope for some of us if we take a bit of care then.
Nice one Mark, and James of course....

So is it a full days work for the walnut blast jamie?

Yes mate, not just the blasting which is fiddly but the strip and reassemble of bits and pieces.
