colsoop Posted February 28, 2008 Share Posted February 28, 2008 (edited) Right i did search but couldn't get any real life reading of the stock twin turbos @ 1 bar. I recently wired up my AFR gauge (AEM wideband), Accelerating in 5th gear at 20 mph the boost goes up to 0.6 bar the AFR's only go down to 13.2, this seems too high to me. When you get in to pre spool at about 3k the Afr's go to 12.6 deviating down to 12.2 then when both turbos are online the AFR's are 10 It seems to hover around high 12's mid to low 13's on aything but both turbo's. Does this sound off ? Thanks Colin Edited May 15, 2008 by colsoop (see edit history) Quote Link to comment Share on other sites More sharing options...
Ian C Posted February 28, 2008 Share Posted February 28, 2008 That sounds completely normal for a stocker, in fact I've seen 14:1 on the first turbo. -Ian Quote Link to comment Share on other sites More sharing options...

Sheefa Posted February 28, 2008 Share Posted February 28, 2008 Same or very similar values for me Col on my hybrids IIRC. Although they did blow up later but due to misuse by the previous prat owner! There was always the occasional hesitation on my old AEM Quote Link to comment Share on other sites More sharing options...
