Guys, I was reallly frustrated about this so I called JD. I had to give him my mother's phone number, but he finally came out with it. It was Bisi's d16 build. He called JD after he was unable to make over 420whp on his own. JD strapped it on the dyno and with his magic tuning knowledgeabilities, they made the numbers said here before the massive torque from the d16 blew the rollers apart. Since it hit the 500 mark, and there was still 5000rpm's to rev out (thanks to bisi's super all moter skillz) Bisi is going to assume it was going to make well over 700hp, so he is coming out to the press in the next week to say his d16 make over 800hp, on 87 octane to boot. Good work, JD!
