    Does the Holley #80513-1 have a secondary power valve in stock configuration.

    Its it is jetted 84 pri and 84 sec so I would think it does, but since it is a HP model I would have thought differently.

    The reason I ask is I am compairing jetting of the Holley vs a Mighty Demon 850 which is supposed to flow more than 850cfm to see evidence that it actually does.

    The Mighty Demon is jetted 85 pri and 93 sec with a plugged secondary PV.

    Both have a 1.56 venturi and 1.75 throttle blades and #31 squirters.

    The Holley does have a 50cc sec pump.

    A 80513 and 80513-1 stock should be 84 square, 31/36 shooters and both pri and sec. 6.5 PV. My 950hp has a sec. PV also.

    Was it the difference in a 80513 and 80513-1?

    Is a 80676 950 better than the 1000 hp? I know it cost more.

    There is no 80513......just 80513-1 and 80514-1. Both are 1000cfm, the 513-1 is downleg style boosters and the 514-1 is annular style.
