Getting a custom grind cam swap and will continue to spray the 150 shot on the otherwise stock internal motor. Hoping to hit somewhere around 600 rwhp when its all said and done. Just wondering how I can tell / know if I need a boost-a-pump? Already have the 255 intank for the 150 shot....think that I will need the boost-a-pump?

Thanks,
Brian

Nope, the walbro will be enough for ya, no need for a boost a pump.

just don't forget about those weak rod bolts at your power level your aiming for.

Not only the rod bolts but the rignlands get weak with that amount of instant torque being applied at once. Progressive controller or dual staging will help this out a lot.

Best way to find if you have a fueling issue is to look at fuel pressure. At your highest demand/load does your pressure drop off? A few pounds no big deal, but after about 5psi you may want to start thinking upgrading cause the more psi you loose the more you will go lean.
