You know the power. I believe weight is ~1385kg = 1.385 tonnes. Easy enough to work it out from there.

1395kgs for saloon
1410kgs for wagon

265ps = 261.3bhp


so

saloon= 261.3 / 1.395 = 187.3bhp/1000kgs

wagon= 261.3 / 1.410 = 185.3bhp/1000kgs

MY04 is lighter than the MY05 then, unless the wagon is heavier which stands to reason.

Also 265 is PS not BHP

Did the sums recently to compare against the car I have :
MY98 Wagon with PPP 1270kg 250bhp 196.9bhp/ton

MY05 Wagon 1410kg 225ps=222bhp 157.4bhp/ton
MY05 Wagon with PPP 1410kg 265ps=261bhp 185.4bhp/ton

did mine as well :

337/1.24 = 272bhp/ton


or to put it another way about the same power to weight as a 400bhp MY04 STi

crisp, is your weight including

bigger wheels
fatter tyres
Stereo ,amp & sub
added mechanical modifications
etc etc

Not to say that you do or anything, but would imagine if someone did there would be a significant difference ?

would the power delivery be more efficiant on a 03 04 05 etc than the classics ? or improved gearing etc ?

Wouldn't have though any significant gains would have been made with the drive train efficiency.

the delivery is certainly different from classic to new age though, mapping is different, new age power delivery is much smoother as opposed to the slam in the back you get when a classic comes on boost. Suppose if you remapped though you could get the same delivery style in a newage but not sure.

the weight of 1240kgs is factory spec kerb weight

I changed my 16" for 18" speedline lites they are slightly heavier

I have a double din stereo but no sub

turbo back stainless zorst which maybe lighter as the silencer is smaller

Only really increase maybe the spoiler change from a 4 to a 6 but nothing major

oh and security install
