Robert Posted April 18, 2006 Share Posted April 18, 2006 1.4 bar i think is the max 550s will run with a t61 Link to comment Share on other sites More sharing options...
Robert Posted April 18, 2006 Share Posted April 18, 2006 you will need a FPR to increase fuel pressure to get 1.4 bar though. Link to comment Share on other sites More sharing options...
Pig Posted April 18, 2006 Author Share Posted April 18, 2006 you will need a FPR to increase fuel pressure to get 1.4 bar though. Even on a uk spec? Link to comment Share on other sites More sharing options...
Robert Posted April 18, 2006 Share Posted April 18, 2006 550s are 550s on any spec. Link to comment Share on other sites More sharing options...

terribleturner Posted April 18, 2006 Share Posted April 18, 2006 Don't forget they limits of the autobox That's whats gonna hold me back.....to start with Link to comment Share on other sites More sharing options...
Robert Posted April 18, 2006 Share Posted April 18, 2006 LOL same here James. Then i'll get the BL box. Link to comment Share on other sites More sharing options...
Pig Posted April 18, 2006 Author Share Posted April 18, 2006 Auto box can handle about 500?? Thats about the limit of a T61 anyway. Must be honest though, would be pretty gutted if it went pop! Run the car with out the TC fuse, would have thought that may help end the auto box's life early! Link to comment Share on other sites More sharing options...
Pig Posted April 18, 2006 Author Share Posted April 18, 2006 Did you get a single kit for your astrio in the end then rob? Whats your spec? Link to comment Share on other sites More sharing options...
Robert Posted April 18, 2006 Share Posted April 18, 2006 ive been told 1.6bar would be really pushing the auto box, so until i get a BL one it looks like i'll be stuck with 1.4/1.5bar Link to comment Share on other sites More sharing options...
Robert Posted April 18, 2006 Share Posted April 18, 2006 sp61 turbo, emanage, 650cc injectors (maybe 550cc), aeromotive FPR,40mm wastegate,stock auto box, oil/auto box coolers,twin fuel pumps. Although im told the sp61 can flow about 600-650bhp. Link to comment Share on other sites More sharing options...

Robert Posted April 18, 2006 Share Posted April 18, 2006 im using the blue emanage right now, 2 row rather than 3 row, i know dude used a 2 row on his supra at some stage. Hopefully will be getting fitted at the end of may, recieved most of the bits. Link to comment Share on other sites More sharing options...

terribleturner Posted April 18, 2006 Share Posted April 18, 2006 Im gonna run a 2 row on my T66 to start with, although i have been tempted with a 4 row ata DAMN good price Link to comment Share on other sites More sharing options...
Pig Posted April 18, 2006 Author Share Posted April 18, 2006 I went 3 row as i will want a bigger turbo! I felt 4 row would be over kill for most turbos! Link to comment Share on other sites More sharing options...
Ian C Posted April 18, 2006 Share Posted April 18, 2006 Just wondering what boost i will be able to run with this setup! UK Spec T61 550cc injectors Greddy 3 row front mount IC Without winding the fuel pressure up, 1bar tops from my experience. You might run more but you'd be north of 90% duty cycle. This is from having seen the duty cycle on 530cc injectors on a T61 at 0.8bar boost, with I think 38psi static pressure - not sure what people are basing their 1.4bar estimates on -Ian Link to comment Share on other sites More sharing options...
Robert Posted April 18, 2006 Share Posted April 18, 2006 yup Ian is correct, 1.4 bar is something like 98-100% duty on the 550s. You would try to keep within a few % of 85% duty to be safe Link to comment Share on other sites More sharing options...
Robert Posted April 18, 2006 Share Posted April 18, 2006 Ian a few member are running 550s on a t61 at 1.4bar, which a highier fuel pressure and really maxxing out the injectors. Link to comment Share on other sites More sharing options...
