fueling for 750whp?

getting a 6266 precision and want to be able to hit 750whp. I read a thread from 2017 saying I would need a stage 3 lpfp and PI to hit this. currently I have a fuel it stage 2 bucketed, and want to get a Helix for the hpfp side. what power would this be good for realistically?

A walbro 450 is good for 600-650whp MAX

Gonna have to add another Walbro 450 or move to a walbro 525 then you'll be upgrading the Ekpm(fuel pump module) with a bpm4 (700$)to handle all that voltage the fuel pumps will be drawing, if you're going PI you don't need helix to make 750whp since the second walbro 450 will help feed the pi injectors. Just make sure you get big enough PI injectors.

My advice is get Pi and max out your single walbro 450 with a good tuner and move up slowly from there after 600 whp you have more to worry about with tires/suspension /clutch, if you're auto forget 750whp reliable or for long at all.

As others have said a single 450 will not get you anywhere close to 750. A bucketless stage 3 style with 2 450's should get you there and be the cheapest option. As for the helix possibly the extreme 4x will get you there. 750whp on a stock block is not going to last too long.

My stage 2 single 450 gave up around 550. Twin 450's got me past that and then I was turbo limited chasing 700. I was using EOS's port injection.
