After we swapped from Phoenix's smaller 9.5-inch (245mm shell) converter to their 10.15-inch (258mm shell) converter, we took the Laguna back to Westech Performance for another session on the Superflow chassis dyno. Here, Westech's Ernie Mena makes an adjustment to the carb squirters. We found that the tighter converter turned on sooner, demanding more fuel at a lower rpm. For that, Mena added some jet to the primaries. The bigger squirters helped eliminate a dead spot when rolling into the throttle off idle.
