I have a 1915cc with Kadrons. Built by VS in Hawaiian Gardens in 2013. Bought the car with 3,000mi in March 2017, have 9,000mi on it now. Average between 22mpg-25mpg.
MPG’s get bumped up if it’s solely highway driving to around 30mpg at 3200-3800RPMs with the 3:88 Freeway Flyer. Given the cheapo gauges, I refuse to believe I’m cruising the highway at 88mph at 3800RPM.
