bignum Posted December 19, 2010 Share Posted December 19, 2010 Good find, now my head hurts:), this may explain the slightly higher hp results people get when running in parrallel. Quote Link to comment Share on other sites More sharing options...
chrispot Posted December 19, 2010 Share Posted December 19, 2010 http://www.scipub.org/fulltext/ajeas/ajeas32342-349.pdf Found this during my research - for anyone that is interested ,its supra/soarer engine data so always good to know interesting read, do you know of anyone that has run there turbos in series, just one point your post title says sequential or parallel, the article is using turbos in series and parallel, i know that you a clever man but from your post title it looks like your comparing the sequential setup that the supra uses (one after the other) to the one in the article (one connected to the other). i don't mean to offend you, good find regards Chris Quote Link to comment Share on other sites More sharing options...
mellonman Posted December 20, 2010 Share Posted December 20, 2010 the maths show better figures in ttc but the fact is i like the sequencial but everyone has the own likes and dislikes Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 20, 2010 Share Posted December 20, 2010 Good find, now my head hurts:), this may explain the slightly higher hp results people get when running in parrallel. No it doesn't, as the article is talking about compound turbocharging, where the compressed air out of one turbo then goes into the second one. The sequential Supra setup isn't covered in that article. Quote Link to comment Share on other sites More sharing options...
jagman Posted December 20, 2010 Author Share Posted December 20, 2010 The article shows a methodology for testing And actual data , for example turbine temps , finding actual data is rare . There are also references to further papers in particular pre compressor alterations which I am looking at . Like any project you need any and all infomation that has been done before , it saves doing things that just don't work and have been tried before . So far I have not found one paper on what I am trying to do , but lots in similar areas. The soarer used parallel and supra seq , Toyota would have done studies but they are not published Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 20, 2010 Share Posted December 20, 2010 It looks like compound charging is worth looking into, if that's what your plans are Quote Link to comment Share on other sites More sharing options...
jagman Posted December 20, 2010 Author Share Posted December 20, 2010 It looks like compound charging is worth looking into, if that's what your plans are I did look into it long ago and it got complex !! So I'm restricting myself to pre comp WI and pre comp swirl as a combination effect , still complex but less so than compressor matching and far cheaper !!

Ian C Posted December 20, 2010 Share Posted December 20, 2010 What about pre and post comp WI? Pretty simple to do once you've already got WI in place? Quote Link to comment Share on other sites More sharing options...
jagman Posted December 20, 2010 Author Share Posted December 20, 2010 What about pre and post comp WI? Pretty simple to do once you've already got WI in place? That is also part of the plan but may not be necessary , once water goes beyond 375 deg then there is no evaporative cooling effect but superheated steam , until I can exactly find out what is happening and why exactly temps drop and det is prevented then it's easy to add . Too many changes together make it impossible to allocate what exactly has what effect and what compounds effects Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 20, 2010 Share Posted December 20, 2010 Why not port WI like the WRC cars used? Quote Link to comment Share on other sites More sharing options...
jagman Posted December 26, 2010 Author Share Posted December 26, 2010 QUOTE=Chris Wilson;2985546]Why not port WI like the WRC cars used? The real gains to be made are pre compressor , port WI is more about det control but can be easily added as Ian C said ,hopefully not needed Quote Link to comment Share on other sites More sharing options...
