Spectra Fuel pump
Does anybody know how much horsepower the stock pump that comes in a spectra EFI tank GM 32AFI (67 - 68 Camaro) support? I will be putting using it with an LS 2 around 400 RWHP
The specs they give are
" STOCK-CAPACITY fuel pump 85-115 PSI / 50-60 GPH"

about 550 flywheel hp, based on output specs (+ safety margin)

50-60 GPH at what specific pressure? It takes one heck of a pump to make those numbers at 85psi.
A Walbro high-pressure 255LPH only makes 43GPH @ 90psi.
The pump is likely similar to a 4th gen LS f-body.VaporWorx. We Give You Gas http://www.vaporworx.com
