Join us for an information-fueled showdown as we put the Subaru VB WRX to the test! In this dyno power battle, we’re installing the Perrin Turbo Inlet and a top-secret prototype part, pitting them against the stock inlet to see the raw performance gains. Watch as we unleash the horsepower, torque, and performance figures in real-time, revealing the true impact of these upgrades. Don’t miss out on this exclusive sneak peek into cutting-edge modifications for the Subaru VB WRX that could revolutionize your ride!
Cobb Accessport calibration for these parts is available from www.PREracing.com

Hmm improves driveabilty, smaller part, no bolts just the part, part # is psp-eng-250. I know it is engine….made a little more power. Throttle Body Spacer?
Just as devil's advocate, how much of these could be only noise from run to run? Humidity, ambient temperature, initial IAT, etc?
Seems to me ~3 whp is just variance, isn't? More than 5 maybe is significant?
Thanks, great content!
I wonder how much power you can get from a lightweight crank pulley? nevermind, you can't fit a pulley in you hand. probably an egr jet or a spring
I wonder how much power it will make when its tuned for these mods.
Ahhh Perrint prototype EGR!!?
Perrin? Like the T-shirt company?
Left & right is always from sitting in the drivers seat same for usdm and jdm
It’s a diverter valve.
Also, the removal of the PCV system venturi is stupid. It’s there for a reason, and that’s to keep the crankcase under vacuum during transient conditions. This is even more vital when running larger factory intakes / Inlet pipes due to the reduced depressions in them. It’s not a “boost leak” like Perrin calls it, it’s simply a recirculation from the outlet side to the inlet side of the turbo. A large portion of the energy lost is recovered because it increases the pressure on the inlet side which helps to decrease the pressure ratio of the turbo. Even if it causes a 5-10HP loss, it’s worth it to keep the crank case under vacuum. VAG has been using this system on different versions of the EA888 and for those without it, you’re starting to see people retrofit the venturi.
Does this turbo inlet require a tune after install ?
I really enjoy the content .
Do you think its worth it to remove the coolant lines from the oem inlet to lower intake temps? Would it be negligible and might as well do whole inlet replacement
You are the channel I was hoping to find. I like evidence and that is what you bring. Thank you very much.
im running an e40 ots map. how often do you think i should change my oil? i know it loses viscosity early. i have the 22 wrx
Mystery part a DV ?
