Hey all, just looking for a VF30 compressor map as noone this side of the pond has a copy (or at least has a copy and are willing to share

). If anyone can help me out, it'd be greatly appreciated. Thanks.

BTW, John - if this should be in Gen.Tech. please do move.

Hi 8Complex, you are a famous name on I-club, welcome here!

I've never seen one. I posted the VF23 and VF22 from Mark V on here and I-club FFI and he said that "As far as I can see is the compressor of the VF23 the same as VF24, VF28 and VF29." But that does not help you on the VF30.

Cool, thanks for the welcome.

Yeah, I have copies of the VF22 & VF23 maps, probably originating from over here. Those IHI guys are damn secretive!

Hi 8Complex,

My understanding is that the vf30 compressor is 1.2mm larger than the compressor used in the vf23 and vf24 units. The vf30 has a bronze bearing, PZ-18H turbine housing, same turbine as VF23 and vf24 and an A/R of ~0.63, which is similar to the VF24. The VF23 A/R is ~71, apparently.
