Organic with springs. Called uprated, but AFAIK they all were ever after the R500.
And I'm being told it was marginal.
I have a TTV setup for a 1.9 engine (no springs) that ought to be able to survive +260hp with a sequential box, but this is with bespoke flywheel as I'm moving to 36-2 rather than 36-4 trigger pattern.
But true. It says so in the build manual.
The blue stuff - has it dried up? It can be silicon sealant in spite of looking like Hylomar. I have blue silicon sealant... (But never used it there!)
My Sillylight overheated after spirited track (ab)use. I thought it was a HGF, but it turned out that the water boiled in the water rail above the primaries if the engine was not cooled down properly. In the end a small electric water pump that kicks in at +95 degrees in the water rail was the cure
