Just picked up a '22 WRX. Not first sports car or even race car, but first Subaru. This thing is a hoot. The engine pulls hard up to redline, and then cutoff - argh!!!

Before kids, I used to race a 1982 911SC and 1972 240z with a Rebello race motor. I learned to drive on an '82 Subaru GL wagon. Usually, when you're approaching redline, the motor stops making power and you're just revving. Not with the new WRX. This thing feels like it could pull to 7k no problem. Will be interesting to see if some of the mods coming out will allow the motor to sing to higher rpms and up the boost a little.

There is sooooo much potential for more power in this motor.

Sounds like you'd be right back in the same boat as the FA, and even the EJ to an extent. I bet it would ruin the drivability journalists are praising.
Very possible. It's just very interesting how hard it pulls to 6k then cuts off. Feels like there's way more potential.

Yeah, just about every forced induction engine does that. It's because at the end of the power and the blower is outside of it's efficiency range.
Interesting. I have only had NA vehicles in the past. This is my first turbo. With NA motors, they lose power near the redline. Didn't realize turbos don't act the same way. Thanks for the clarification.

Probably not. Air flow at lower rpm won't be affected by raising redline, unless you modify the turbo. It should just lose power at higher revs before hitting cutoff.
What I would have thought too, but this is my first turbo. It's possible I just don't know what I'm talking about :)

^^^ Great info, thanks. Interesting that charts show a dropoff around 5k to 5.5k because it still feels like it's pulling hard. Will be interesting to see what the tuners come up with.

Even though I know nothing about turbos, and might be talking out my butt, 6k still seems really conservative. Doing some "fun" runs yesterday, and that 6k cutoff is jarring. It really is still pulling hard at 6k. I'm sure there's a bit of room here.
