Default Id1050x max hp on pump

How much hp can Id1050x make with 93 octane and 50/50 meth injection and a walboro 255?

I've heard the 1050x are only good for 400whp. But I've also heard they can do 460 so I'm not sure.

Is it worth upgrading fpr?

Your question could probably be better answered in the built motor discussion or engine management and tuning forums.

I have ID1050's on my hybrid engine with a Deatshwerks 255lph fuel pump tuned for 315 wheel horsepower and 300 pound feet of torque. I wouldn't recommend going over 300 pound feet of torque with a stock 5 speed manual in a bugeye generation WRX....unless you want to destroy the transmission.

Yes, you will need to upgrade the fuel pressure regulator. You may also want to install upgraded rails that will fit pulse dampeners. You don't really need rails but the pulse dampeners really help with driveability.
