Walbro 255 questions

Hey guy i need how much horsepower ONE walbro 255 can handle.

im looking at buying the walbro pump with the hotwire kit for my 95 camaro's new motor. It will be making in the neighborhood of 650 flywheel hp.

Also if i need to run twin walbros whats the best way to go about doing so?

What are you basing the HP estimate on? How will that HP be made?

HP based on a motor build pretty close to what im having done and it made 638HP on an engine dyno. It will be made naturally aspirated and might see a 150 shot.

For the record it wont be an lt1 its a gen 1 SBC. I'm just looking for some options on fuel pump setup.

Thanks
