That's all I can say. I race it competitively in the Unlimited Class Time Attacks here in Japan
so I decided I would always advertise it as 276HP, following the Gentleman's Agreement at the time of manufacture. (RB26DETT routinely dynes around 310-320 Crank HP despite being advertised as 276). I know that's gay to leave it unanswered, but I can answer it a different way. The engine makes 18,000 dollars of HP.
