Power Valve Size at Judy Acosta blog

Power Valve Size. Rated in inches of mercury (inhg), as an example, the most common rating is a 6.5. Holley provides a handy chart that breaks down power valve size according to engine cubic inch displacement (cid) and vacuum rating, so you can easily identify which power valve. This reduces the primary jet size by that same amount. Holley carburetors utilize a vacuum operated power enrichment. A 65 rating will coincide with 6.5 hg. The power enrichment system supplies additional fuel to the main system during heavy load or full power situations. Illustrates 1 stage & 2 stage and which gaskets are used. What is the different power valves used on autolite, motorcraft & holley carburetors. Each power valve is stamped with a number that indicates the correct vacuum opening point. To know which power valve you have, all you need to do is look at it. Based on the rating of the power valve, it will open to allow additional. Generally, the power valve circuit will introduce the rough equivalent of 6 to 8 jet sizes worth of additional fuel. Power valves are rated in inches of mercury (hg);
