Sounded a bit low and had to double check the Subaru Australia site.

Quote:
Look under the bonnet and you’re confronted with a 2.5-litre DOHC turbocharged Boxer engine with Electronic Throttle Control and Active Valve Control System that generates an awe inspiring 221kW of power. Producing 407Nm of torque at 4,000rpm in manual models and 350Nm of torque at 3,000-6,000rpm in automatic models, the WRX STI is sure to get your heart racing.

So that's 275 hp at the flywheel.

And how much power is lost through the drive train (typically) ?

(Im trying to understand the "typical" base hp atw figure so when I see the dyno results after the mods, I can see how much has been gained (while fully aware that all dynos are different, all engines are different, etc))

On a 2.5L it should be making more than that.

Can any of you guys post up some graphs?
My graph.

Here is mine usual twinscroll stuff running VF37, nearly same result when running VF34 lol - might be dud vf37
I was contemplating getting the BBK-M as well but when twinscroll in the end for something different
BBK-M = TD05-18G?
BBK-L = TD05-20g?

VF37 and 34 have the sma ecompressor housing so it should make the same. Just earlier due to TS.

Bought some tomei unequal length headers and the PW CAI will be going on with the tune next week, I'm still sceptical about the BBK-L and think it should go 350. Will update next week.
