Ever wonder why you didn't much gain in power when you added on a bigger throttle body? Skunk2 has a tech video to show you why that may be and how to fix the issue.
The Skunk2 Throttle Body Port-Matching video after the jump!
This weekend marked the first race of the season for the Project SI with the Snake River Autocross club. Over the winter the car saw a few minor changes to it, with the addition of a rear camber kit from our boys at Skunk2 and a new set of Dunlop Star Specs (235/40/17). If you remember from last year the Project SI runs in a class unique to this SCCA club. The class is called Idaho Motor Sports (or IMS for short), this class is for the local forum that brings out pretty much any street car to compete. For this class the rules are pretty simple, because there are only 2 of them: 1. Street Legal and 2. Street Tires (140 Tread wear and up). The IMS class is filled with almost everything you can think of, high horse power Evolutions to 1980s Honda’s and big mix in-between.
