Message I didn't go!

Event was yesterday, car was on a dyno on Saturday getting the map checked out and refined some more, car was responding very well to small adjustments but after 6 pulls it dropped power and developed a knock :( Car hasn't been run since so I'm praying that it was caught early enough to minimise damage to other components.

2 days earlier I was on a grip limit course doing constant circles on a skid pan so I suspect that caused the damage. Unfortunately I don't have data logging on oil pressure.

So, next event is in six weeks, I have a spare engine so depending on damage we'll repair or swap out. I'm now looking at dry sump setups. All opinions welcome at this stage

I currently have the SZ sump with drains from the head back to the sump.


PS this is the dyno plot before it went wrong, Hub dyno, 21 psi. GT3071 turbos. Lots of refinement still to do, still need to fine tune the VTC cutover, still need to dial in exhaust cams but we just didn't get that far. Thanks to TurboNoz in the Uk for helping me unlock this cars potential
