[Craig 930 RS]

At least I found no true evidence of a shabby build within.
I chalk it up to ultra high internal (NOT oil) temperatures.

I intend to at some point install an appropriately sized & designed intercooler of a higher heat capacity - probably the 965, or full bay 930 if it tests out to be the right IC for my build. Hard to beat the 965.

I think the fuel head and niresist (cylinder to head sealing) rings will go a long way towards helping prevent these problems in the future.

I'll try to run on days where the ambient temps are perhaps below 80-90 or so.....and continue to use race gas all the time as the PO did.

I also plan to design an air cooling rig using a SPAL fan for the center section of the turbo
to possibly help with bearing temperatures. It certainly can't hurt to have some air to assist with the oil cooling -
