hi can anyone tell me what bhp and max boost i can run up to with a vf29 turbo ?. before anyone asks i have engine/intercooler that is capable of up to around 400bhp. thanks

 

oh thats not good then, have been running that was hoping to get up to 360/380bhp with my new engine.

 

Think you will need an 18g for 360-380hp.....

 

IHI VF29
(425cfm at 18psi, 250-325whp, Bolt-On)
This is the standard equipment turbocharger on the JDM V6 Subaru Impreza WRX STi. The VF29 is nearly identical to the VF24, with the same compressor and exhaust housings. However, the compressor wheel in the VF29 has been changed slightly. The changes made to the compressor wheel in this model are generally viewed as improvements, and as such, this unit is typically chosen over the VF24. Has a different location for the pressure hose on the wastegate actuator.
Expect to achieve full boost with the proper mods and a quality tune between 2900-3300rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and proper engine management is highly recommended for all vehicles.

 

thanks for that will have a chat with the mapper
