You have to go HUGE With hydromats to keep from fuel flow issues.It was entirely the Holley Hydramat. it was the wrong size outlet with only 3/8” which is too small for suction side with our fuel flow. And the mat was totally clogged. Pretty sure this has been our problem for a year and a half. The pumps would starve and fail. Went thru 5 sets of pumps and a ton of changes to the fuel system fighting it.
If you Data log fuel pressure. We found hydramats to drop fuel pressure under hard, high load 0-100% throttle application.Actually found out that a new hydramat that’s not clogged can be very small. A 4x4” mat can flow 700hp. The issue is when they get clogged and more importantly the outlet size. It’s all in the details. Haha
but yes you are right. We got the Huge one that’s 30”x18” that has 3 -10 outlets.
