Are you using the stock Ur-q oil cooler?
The WR is being pulled this Friday...
It's going to be a long week... ;)

On a related note if anyone is interested in getting their stock 3B flywheel lightened please let me know.  I know those are already light compared to the stock WR/WX units however I have a CNC program a custom stand and access to a machine to make them even lighter.
Last night we machined three flywheels with over 3lbs reduction in the outer edge alone... not to mention it looks like it's ready to be installed in an IMSA car... ;)
I'll post the pics tonight.
