i guess its no worse than hes been running so far, a single walbro with 500+whp on gasoline everyday. for everyday use i just figured 1000whp for 2x walbros x .70(for e85) = 700whp. i didnt mean they couldnt do it, i pushed over 600whp on a single walbro on my setup, just that for an everyday setup thats kinda pushing the walbros imo.
