Manufacturer Description:

Often you will hear a racer say, “I made two jet changes, but the engine still didn’t run properly.” The reason for this relates directly to the jets being used. Other jets are mass-produced with a wide tolerance, then plated. Many of these jets use the same orifice size with the only difference being different angle tapers that supposedly change the flow-rate characteris-tics. Other jets also use a slot that requires a special, expensive tool to install. Ultimately, these slots become damaged, and that damage creates a turbulence that severely affects the fuel flow by as much as 50 percent.

MaxJet™ Precision Carb Jets are available from 0.050" to 0.120" in gas-oline jets and from 0.121" to 0.140" in alcohol jets. Sizes are in 0.001" increments and are compatible with all known racing fuels. MaxJet™ Pre-cision Carb Jets are easily matched to Holley jets; simply find the Holley size that you are currently using on the left and cross over to the MaxJet™ column to find the corresponding part number.
