Do you think the Walbro fuel pump that comes in Comptech SC kit will be sufficient for the fuel supply/flow need in a 400-500whp application? Will be running 750cc injectors with 100 or 104 octane.

I called Comtpech and they told me that the fuel pump in their SC kit which I have is a Walbro GSS342 with a flow rate of 255 liters per hour.

If that's not adequate, can anyone recommend a make/model and flow rate that it should support?

Thanks.

The fuel pump will be fine for your application. I am going to use my fuel pump for a turbo system w/ same HP levels.

It's more than enough for you.

Thanks, I wanted to make sure since I'm upgrading quite a bit with a complete motor build and blower upgrade.

The 255lph Walbro can free flow enough fuel for 650hp or so. Pumps don't run without restriction though. The Stock fuel lines won't. 4-500hp, the Walbro pump is enough.

not to bring this too off topic, but what blower upgrade are you doing?
