I think it's a vf35, I have the same model and it's been mapped by Andy F to 355bhp. Don't think they will do much more than that.

If it's a PPP then I guess it's a UK so will have an IHI VF35 IIRC

BHP good for 340, torque less but still over 300 :)

That's a good figure from Andy F on pump fuel :)

it will be andy i would use and thanks for the info guys looking for 400bhp had 351bhp 353ft/lb torque on my blob wrx

400 is a no-no for the VF35 unless you start adding methanol (a lot of methanol).

At the boost / flow required for 400 BHP the VF35 will be heating the air rather than compressing it efficiently.

I think Andy does a billet 20g that won't be far off the four hundred mark.

He said he was often surprised how well some of the last blobs perform. ( or words to that effect )

ok i didnt think it would do 400bhp i would leave the 35 on if it made 370ish so a andy f 20g billet it is then unless anyone know of a better turbo for 400bhp cheers pete

SC40 is a rebadged Blousch which is meant to be good as it the Alan Jeffrey 400 BHP jobby, who's name defeats me.

Then there is the MD 123 series

Choices, choices :D
