No room for a dry sump at this time. Current target AFR is 11.8, at full throttle the O2 datalogs shows that AFR varies on both banks from 11.5 to 12.1

Im curious to what side is 11.5 AFR ?

Are you using race gas or e85 ?

Thanks

The Left "passenger side" is a running slightly fatter. I'm using C16 fuel.

Looking for a Garrett Turbocharger Turbine Housing PART# 408532-0034

[cgeise]

have you checked with EXILE turbo in Calif??

[RAIV-Z]

Turbonetics came through with one housing and enough info to allow me find another, both will need some machine work to fit the turbos. We're changing from to 0.89 A/R to 1.23 A/R due to excessive back pressure.

[RAIV-Z]

After a little machine shop massaging, the Garrett housings should fit the Turbonetics 88's.

[RAIV-Z]

Mockup indicates some additional turbine housing machine work is required as well as some potential clearance issues with one of the radiators on the drivers side.

[cgeise]

you should be much happier with the performance and the lack of back pressure

Did you guys ever get those new ARP2000 head studs?

Yes, haven't cut them down yet. Waiting for the block and heads to return.

[RAIV-Z]

The engine refresh took a bit longer that anticipated, short block is together and the heads are ready for assembly.

[RAIV-Z]

Getting closer.

The Raven's updated engine is running.

Quote from Ed Page
"Update for the Raven’s first outing of 2021 after major drive train changes.
The engine seems to be running well from what we can tell. We were unable to make any full or half passes due to transmission slippage. 1st partial pass was off idle and started slipping in 2n’d gear. Engine Oil pressure looked good when cool, a bit low when hot. We were using VR1 20/50. We'll try VR1 50WT before adjusting the oil pump pressure.
On one of the passes, we lost one of the turbocharger bellmouths, looking for a Turbonetics 20817P. The transmission is out of the car and will be checked out by Automated Transmission early next week. Also looking for another Rossler TH400 transmission, promod preferred. We will be adding another sensor to monitor internal transmission pressure which could have pointed out we were having a problem with the transmission."

We hope to see everyone this Friday & Saturday at the STREET OUTLAWS event @ New England Dragway in Epping NH.
