My Puma got a carbon clean after 12 years!

At 12 years old, Orxy got a well-deserved carbon clean - look at how much gunk had accumulated there 😳

Superb job by Carel and his team at Racing Technik - https://www.racingtechnik.com/! 😃 

That workshop is so clean, it would make Ron Dennis blush

That does look clean…

Interested In how they do it in situ like that?

they blast ground walnut shells into the ports, with a vaccum running on the other side to scoop up all the debris - at least that's how I understand it

Yes, but is it the right shade of grey?

Was there not a cleaning service that Ed China was promoting as well? I think it was maybe done with everything in situ but I can't remember for the life of me what it was called or whether it was as thorough as walnut shell blasting.

There’s another thing called carbon clean which seems to involve lots of soapy bubbled coming out of the exhaust. Always seemed a bit like snake-oil to me that kind.

yeah, from what I've read, that stuff doesn't really work

I'm assuming that engine has EGRs from the factory. I wonder what it would look like if they had never been fitted?
