    Thanks goes to Meddy, who found it originally.

    As it refers to crankshaft HP, I'm assuming that's the same as the fly figure. Makes it a bit difficult to work it out for you rwKW people.

    According to the calculation, I should be running 640s and the stock JDM Spec R is already maxxed.

    at idle it's about 35psi... but it will increase as boost pressure increases I think 40-43 would be a good number?
