Questions & Answers Ask a Product Question

What’s the horsepower rating for this carb?

Asked by BRIAN on January 08, 2019


There is no true way to rate a carburetor for horsepower. There are too many other variables to consider. Holley has a carb selector tool that allows you to put in your engine specs and get a recommendation for carburetor size. It is on their website and is a free tool to use.

Hi and thanks for your time today.

How much boost are these carbs rated for?

thanks again

Asked by DWIGHT on December 08, 2018


It honestly depends on the type of application that the person is building, a pressure box application, tunes differently than a Hat type application. Jetting, Power Valve referencing/tuning and float adjustments are all parts that need to be considered in all turbo applications.

There is no specific psi rating on carbs it depends on the engine combo capabilities and tuner knowledge, but baseline they would be safe 14 PSI with Proper A/F ratio in properly setup turbo applications.

Blow through twin turbo 302

Works fairly well . Float levels were way high on 8psi of fuel pressure . But after some adjusting on the whole carb works well .
