:cry : at 17psi making 258, if that is true then there must be a lot that you arent telling us about the engine!
b19bal does this
a ported head done well and decent cams will consume more air than standard and make it feel laggy but power at the top when the airs filling the engine
Really make sense to you, cause if so i think you need to learn a bit more yet!
Ported head means lower gas speed so LESS intake of air off boost, and cams well im not even going to try and explain that in a post but critical things are stuff like lift on overlap.
