Hi all, hoping someone can shed some light. I know Ford claims the FG XR6T has 270 flywheel kW. However, I have been told Ford's rating is quite a conservative number and it is actually closer to 300 fwkW. Someone also told me about the 10% overboost capability - I will check my handbook about this later; If I do the math, although a little rusty - 270 x 10% = 27, therefore at times it must peak at 297 rwkW - pretty close to 300fwkW. Anyone know anything re: FG XR6T (stock) power.

Well mine was just over 240 at the wheels standard, if that helps..

So I guess that would mean something around 290+ at the fly, reason why they gave conservative numbers for the turbos was because they didn't want the power figures to affect XR8 and GT sales

Thanks that makes sense. 240 at the wheels - well if I allow for about 15% driveline loss that places your vehicle at about 283rwkW, pretty close to what you thought at 290. Although I am only guessing at driveline loss it may actually be more. Anyone know what power (%) is lost through the driveline (ZF 6 spd Auto).

Thanks, if that be the case then the XR6T's must be very close to around 300 fwkW - ie: 240 rwkW @ approx 20% drivetrain loss = 300 kW at the fly. Looks like the numbers stack up to what I have been told. I know all about the variance between dyno stuff - but it would appear that it is true, that Ford's 270 kW number is quite conservative. Interesting.

Good point - were you using 98 octane fuel when you ran the 240rwkW or 95?
