Finally got around to racing my cars against each other. They were both running 16 psi of boost. I expected the S2000 to be faster but really had no idea until my friend Mike hopped in the S2K and raced me. I’ve ran the S2K up to 22psi and it’s definitely a lot faster than 16. The Iroc has never seen more than 16 psi but I think the turbo is starting to really restrict the exhaust, it’s not much faster than 12psi.
