As the heading says, how much boost should I expect peak/ held. It's a MY99 WRX RA, IHI VF29 turbo, K&N induction, HKS system with standard downpipe. Only other engine related mod is HKS SQV.

Also, can a turbo boffin explain the charecteristics of the VF29?

I thought that the biggest in the range was the VF22 and the higher the numbers went, so the smaller the turbo. Is this the case?

i was told the VF24, VF28 & VF29 are same turbo, just minor difference, they are good for about 310/320bhp.
