General consensus is c450+ bhp... at the flywheel.


So, for ATW:-

450 minus c.21% friction/tranny losses = c.355+ bhp = c.265+ kW

Stock turbo is the VF35 (for the single scroll UK car). Or VF37 for the twin scroll JDM STi.

I believe both left the factory with 265PS = 261bhp = 195kW. (Some mappers have observed that very rarely do the cars actually make the full monty).

Dealer-fit PPP package takes it to (an alleged) 305PS = 301bhp = 224kW.


For the record a VF35 can be mapped to around, on average, c.330-340bhp = c.246-254kW

And the VF37 is normally a 350+ turbo = 261+ kW

Sorry, forgot to mention I was talking about the VF37

Seems like the turbo will be maxed out in a few months then =)

265kw atw should do the job for me! Glad to find out that the standard internals and the turbo can take it so I can just get away doing the Stage 3/4 mods

Just to make clear, those figures mentioned in post #5 are @flywheel! As that's what manufacturers always quote in (because it's a greater figure i.e. marketing and all that).

You need to subtract around 21% from each of the figures to get to @wheels numbers - which you can quickly do on a calculator with a "%" button

Out of interest, do you hail from Aus or NZ (due to your chosen kW units)?
