EVO 10 DOUBLE-PUMPER

Buschur Racing EVO X Double Pumper ReviewFeaturing the same technologies and solutions as the company’s proven EVO 8/9 “Double Pumper”, the extremely-affordable EVO X “Double-Pumper” solution is also a stellar performer. The pair of modified Walbro GSS340 pumps feed into a Y fitting below the hat. This allows for a single 3/8-inch bulkhead fitting up top. A single 3/8-inch or – 6AN line can be used. On the flow bench, the system performed very well. To our surprise, the single outlet performed better than the individual lines running into a tee on the flow bench. Again, the modified pumps showed some of the least flow loss as operating pressures increased. Feeding fuel to a 750+whp 4B11 running 35psi of boost pressure should be no problem for this setup. A core exchange is required.
