Looks like I'm being a bit pessimistic. Having watched the way it pulls away from my car at Snetterton I think I might lose this one.

327.8 bhp at wheels

EFI rolling road soon

[Exmantaa]

Do they also measure the roll-out to see the drivetrain losses and calculate enginepower?

(is it a single or double roller?  Doubles can be hard for tires, so put enough air in!)

I'm back There was a BMW on dyno before me and it made around 8 hp less than the way it left factory Was over 100000 miles on the clock

[CHILL Gone DUTCH]

The car made 338.9 hp But all might not be well The car was running rich With a AFR of 11.2 this was measured on the dyno and my own wideband read the same So I have to find out why

[CHILL Gone DUTCH]

Will start off by studying the log tonight and then checking exhaust and lambda

[Nev]

11.2 does sound so rich to me, what would you expect ?

 

[CHILL Gone DUTCH]

Should be 11.8 But I have not yet checked the data this could of been caused by the inlet temp correction Do study data after T if the data says 11.2 after correction it sounds like somthing mechanical

[Exmantaa]

I do assume this is engine power...

 

11.2 or 11.8AFR will not do much for power in a supercharged set-up.

[CHILL Gone DUTCH]

Just for record the obd power run at over 1000 hp on the dyno So as expected it can't be run at the same time

339hp or +1000hp seems not quite a match haha. I stand corrected.

Do you have a dynosheet? Like Exmantaa said: 339hp @ wheels or cranck?

And did you manage an OBD powerrun on the way back; for direct comparison without doing any engine mods? Or too slippy out there?
