Whitesupraboy2 Posted February 12, 2006 Share Posted February 12, 2006 On a TT you hear numbers of 650 - 900 floating about. is this celcius? (depending on level of mods) I just wondered does anyone actually know what they should be on a NA? Also what exactly causes the extra heat (i know it to do with the turbo's but just like it explained why) Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted February 12, 2006 Share Posted February 12, 2006 The difference in temperatures is mainly down to sensor position. The lower 600 figures are usually from after the turbo's in the pipe before the cats and the 900's are from BPU plus motors. Higher inlet temps cause the inevitable exhaust temps. High inlet temps are caused by running turbo's out of their design range ie at 1.2 bar instead of 0.8 bar hence the requirement for aftermarket charge coolers and water injection etc. It is indeed in celsius AFAIK. Figures for an N/A mm dunno. No-one usually bothers as you can't push the envelope or really do alot about your EGT's to worry about having to lower it. I'd of said an AFR meter would be more usefull on an N/A Quote Link to comment Share on other sites More sharing options...

Without a mappable ecu though neither are any use. Quote Link to comment Share on other sites More sharing options...
