I have a new combination and switched from a V1 S-trim to a V1 T-trim per Vortech’s recommendation. It’s a 410 with Edelbrock E205 heads and a custom grind blower cam. I’m running the same pulleys I had on the S-trim(6.87/2.95 and tried a 2.7). I had someone get the Holley HP up and running and tune it for me but it’s only making 4lbs of boost and I’m trying to run 10-12lbs. I asked Vortech if I just needed a different pulley arrangement but they suggested that either the engine is too efficient or there is a restriction. I’m using the Vortech mount and I have a 4” inlet pipe and 3” discharge routed like the original pipe would be so I don’t think a restriction would be the issue. Just curious if anyone has any suggestions. Thanks
