Yeah, around 250whp is required to drive away from a stock AP2. They run as low as 14 flat in the quarter mile, low 15's for an NC, so to walk away youd want around 1/2 a second advantage over the S2k in the quarter, and basic maths says that this will take 250whp.

Thats a turbo or very good blower.

Or a 125 shot of spray.

Keep the existing C&P and swap back when boosted. - assuming boost is atleast a year away.

Hopefully will get 200RWHP (150kw) out of a BP motor naturally aspirated, is this what you are after?

You will have a pretty narrow powerband assuming 20% drivetrain loss you are shooting for 240 fwhp from 1.9 liters or specific output of 126 bhp per liter.

Genuinely curious to know upper limits of the BP but I suspect this spec of engine not the love you long time style.
