ATM Innovation XRB Race Series E85 Carburetor

ATM’s E85 XRB Series are our most versatile "race" carburetors with a 4150-style flange and "no vacuum ports".

Fuel is managed by ATM™ all aluminum dual inlet, dual sight-window fuel bowls and the billet aluminum throttle-bodies have vacuum tubes for vacuum advance and PVC hookups. They are available in 5 sizes from 650cfm to 1050cfm (4150 flange) applications.
