I haven't got the silicone piping kit yet, still waiting on supply from the UK. The clamps I have been using are the stock ones.
I borrowed a HKS hard pipe section from Ray Evans a while ago (I must get that to you Ray )
When the piping arrives I will put the good clamps on. I've had a few events since Winton last year when the old rubber pipe split with no issues, so it's a p.i.t.a.
I hadn't touched the rest of the system either as it was reliable. It seems to be the pipe section that goes from the "twin turbo" pipe to the hard pipe section through the chassis rail that is the culprit as I recall Frank and Aaron having issues in the past as well. That is the one that split at Winton as well.
The thing that really burns me is that every single lap I did was getting faster, the last two sessions would have been interesting - so I will have to wait until the 20th of May for the next event there to get that 1.49
