JamieP Posted November 17, 2009 Share Posted November 17, 2009 I'll have to double check the printout on my old laptop but im sure my old supra made 390bhp at 8 psi on a gt4088, i dont see how 8 psi is possible on 330's if im honest.

dr_jekyll Posted November 17, 2009 Share Posted November 17, 2009 deffo 8psi . iv had a few guages on there and all read 8psi. i have the innovate lc1 regularly calibrated reading 11.1-11.3 on full boost , i think the duty cycle is up on 90% witch i know is not good. i would like to upgrade to some 440 or 500s but as yet iv had no fuelling probs. exept the ones i made when i read the emange insructions wrong Quote Link to comment Share on other sites More sharing options...
Homer Posted November 17, 2009 Share Posted November 17, 2009 garrett (prescision)gt 4088, i know i dont need such a turbo for the small setup i have m but its mainly for reliabilityas im not pushing it atall Ah, that explains it in part, thanks Edit - nevermind, answered above. The duty is too high to be safe, which is what I was getting at... What is the fuel pressure? Quote Link to comment Share on other sites More sharing options...
JamieP Posted November 17, 2009 Share Posted November 17, 2009 Just checked and it was 10psi on mine, so 8psi might be possible, found an old video of it at 10psi, looks slow as hell:d http://videos.streetfire.net/video/Supra-gt4088-at-10psi-MPH_90501.htm did you have a na-t jamie? No mate, TT runing gt4088, i only run it at 10psi for the first 1000 miles while i was running it in. Quote Link to comment Share on other sites More sharing options...

JamieP Posted November 17, 2009 Share Posted November 17, 2009 now thats a video ive never seen before! still reasonably quick non the less! My old supra, lots of videos of it kicking about. this was when it was on a T88. http://videos.streetfire.net/video/Supra-burning-rubber_90472.htm Sorry for the hijack:d Quote Link to comment Share on other sites More sharing options...
garethr Posted November 18, 2009 Share Posted November 18, 2009 What about the Boostwerx stuff? Seems to clear the distributor better than some others. Still adds up when you include all the pipework, fuelling, piggy-back, etc., though http://mkivsupra.net/vbb/attachment.php?attachmentid=101327&d=1258505819 This is on a Lexus SC300 (Soarer) rather than a Supra.
