[QUOTE="StevenStarke, post: 11912992, member: 127727"] You are 150% wrong. How is backing up exhaust gas After the turbine wheel going to Increase spoolup? If your slowing the turbine down, your slowing how fast it spools up. You can NEVER go too large on a downpipe. Backpressure is NEVER good post turbine. A 1:1 ratio Pre turbine is good, but you never want back pressure because your exhaust is restricting the turbo. HUH? Boost creep means the turbine wheel is spinning too much creating more boost than desired. This would mean your wastegate was not dumping off enough exhaust gas pre-turbine. You don't control boost creep by putting a restriction the turbine wheel AFTER it. That's called a bandaid. You don't ever put an O2 sensor before the turbo. EMAP on a turbo car will mess up the readings. Yes a typical passenger car does use a wideband sensor and they do see some backpressure, but no where near the backpressure that a turbo causes. I'm surprised you didn't know this? [/QUOTE]
