And from what i can gather the wrx turbo was infact the 13t rather than the 13g,
15g is off a volvo or saab isnt it? Might gain a bit up top with that one, compressor map is on squirrel performance if you want to crunch some numbers, i use 77% ve 0.42 BSFC and 17:1 a/f ratio
i was thinking more of a bypass system like darrens so the GT15 would cut off once TD04 got going lol im not sure about these things but i understand what you mean
This 15g was actually off a subaru they guy had bought it for his starlet but never got round to it,
To be honest im surprised how well it performs was expecting a lot more lag but hardly much more than the K14 hitting full boost at just under 3k and unbelievable how quick the rev counter moves from 3-5.2 now haha
Its mint, and love the fact how i can cruise on the motorway and at just under 3k doing 75mph the turbo doesnt read on the guage More mpg
