Nice work guys - will be interested in having further discussions about fuelling - Methanol will only go so far, and running large amounts of Ethanol-based fuel quickly maxes out factory pumps. Not sure I've found the limit on these factory turbos yet, so will continue to push until they run out of puff.
Hopefully with more people modding these, Terry might do some fuel upgrades for the S63, including a direct-port kit with injector options for either meth or fuel.
Be careful out there fellas - in that thread above they killed a rod in a S63TU at around 700ftlbs...
EDIT: If you need any help installing the JB4 & BCM let me know - I posted a quick guide over in this thread as the BMS guides are a little convoluted.
