Hi-Boost 1g BOV Mod w/ 100% OEM Function

This site may earn a commission from merchant affiliate links, including eBay, Amazon, and others.

The Dodge/Gus mod has been around for some time as a very effective way to greatly increase the holding capacity of the 1g BOV. The mod accomplishes this by blocking the passage that normally provides boost pressure to the bottom of the diaphram. The only issue with this mod is that it works great for the track but creates some drivability issue on the street.
This How-To will show you how to make the Dodge/Gus mod work for both street and track holding high boost and OEM drivability.

First of all, if you have not done so already the Dodge mod needs to be done to you're 1g BOV. I used and NPT fitting instead of the tube shown on their site.

And finally, we add a regulator into the mix and set it to 15-18psi.
This keeps the bottom of the diaphram below the 20psi pressure where the BOV begins to leak but gives it enough boost pressure to operate like OEM when the top nipple sees vacuum.
