NEW DAVINCI ALCOHOL DOMINATORS

DaVinci Performance Competition Alcohol and Gas Spyder Tunnel Ram Matched Setup



The DaVinci team produces a total fuel control carb called the Spyder. Our Spyders offer the most consistent and reliable functionality, from the all out Pro Stock and Pro Mod, to the ET and Super Series racing. Externally adjustable jet pods allow unlimited fuel control on or off the throttle stop. This produces a flat fuel curve throughout a run. The jet pods feature externally adjustable Holley jets that can be replaced without removing the float bowl. DaVinci's reputation for all out performance is impeccable. Extensive modifications by the knowledgeable DaVinci crew are then applied to make gains ranging from 5-50 horsepower over all other modifications. All carb pairs are flow matched and jetted to the exact specifications for your motor. The Spyder is also quality tested on a race engine with float level and idle preset for out of the box operation. All parts are coated to a high luster to add reliability.
