Would anyone be able to provide me with the  rwhp figures that Ford produced from BF series 2 Xr6t  before they decided to detune them  just so ford didn't lose sales for the V8. Also after information or links on recommended upgrades for stock factory parts.  Thanks in advance for any help or info

They only ran 6psi of boost stock and dyno at like 190-210RWKW stock (BA-BF)

 

To up the boost reliably people generally a combination of below:

 

tune (sct xcal/etc etc)

injectors

intercooler

fuel pump

air intake (turboside for that lovely sound)

exhaust

valve springs.

 

stick around and have a read on this forum, there is a treasure trove of information.

I'd hazard a guess that the max you'd get out of a totally stock BFII T would be about 230 or 240rwkw.  Mine ran up 208rwkw, stock aside from a K&N filter in it which counts for bugger all.

 

Think the injectors are probably the first restriction to power limits.

 

Ford wouldn't run a high power knife edge tune because they want to minimise warranty returns...they drew the line where they did and it was STILL faster than the XR8.
