Replying to: wwest (Feb 28, 2009 2:17 pm) But you're suggesting that a 26% increase in compression ratio (9.5 to 12.0) will lead to a 50% increase in fuel efficiency. I don't see how that follows. tidester, host SUVs and Smart Shopper Replies to this message: wwest (Mar 01, 2009 11:14 am)

Replying to: tidester (Feb 28, 2009 9:59 pm) The power increase from CR would result in less turbo on-boost time...... The turbo wastegate could be held open for low to moderate levels of acceleration.
