VF30 and VF34
I believe from the 34's ballbearing design it does spool up quicker, not as much of a difference as a 22 and a 34 but it is noticable.
Also the 34 is going to sustain higher boost pressures because of the ballbearing design.
I heard somewhere that the oil feed may be a little different too. I don't know that for a fact.

VF-30 is a good turbo, I assume that you have all the supporting mods such as Fuel pump, injectors, and a full TB exhaust right ?
Other than that are smaller things, cutting out (if any resonators in the exhaust), samco intercooler hoses, a ram air intake (yes they are helpful if you tune the car)
With those modifications you should be somewhere in the vecinity of your goal. If not an Xede and race gas will always do that trick

yea..i got a full TBE with highflow cat with no resonators..uppipe..walbro fuel pump just arrived today..sti injectors are coming with the vf30..and i have AP..and i have a short ram hanging around until they provide a map on AP for it..
They show gains of about 8 - 10 hp. The stock IC hoses look like a maze gone bad and are ribbed throught making air flow hard to come by. Samco are smooth straight to hoses. More dense air means more HP.
If there is any chance that you could go and get your car tuned, take that up. Off the shelf maps although they wont hurt your car they will not give you all the power out of your car. If you get it tuned you will really see your individual car open up. Tuner companies never make maps for RAI because they have such varied results that to tune one for one car it would be totally different for another.

hey rush, do hoses make that much of a difference...i just got my car dyno tuned yesterday by shiv and i pulled 243.1whp with the following mods:
ihi vf30, sti inj, walbro fp, v7 sti catless up, mrt catless dp, catback tanabe hyper medallion, v7 sti tmic and xede (stage 2 map w/ 91 oct), everything else stock....

The purpose of an intercooler is to cool the air going into the throttle body and also the turbo, creating more dense air, which provides for better explosion in the combustion chamber. Which makes more horsepower.
The intercooler hoses that are smoother rahter than flex monkey rigged hoses will let air flow more smoothly into your turbo. It will make a difference, I have seen on a dyno sheet 8-10. So they are truely no bull.
