    alright something to think about. cheers.
  2. bj0rn

    yeah at the moment 18psi, stock motor, disco, 270rwhp. the other idea was to stay garrett and go up to a 3076. you reckon the stock cams will limit it regardless of what turbo?
  3. bj0rn

    as above, around 18-98 on pump 98 fuel. unopened so yeah stock cams. e85 is only available at a couple pumps in perth so im not really looking to go down that route. my old car did 119-120mph passes id be pretty happy with that haha. 350rwhp would be nice, so whats that around 280rwkw or there abouts? makes 270rwhp on a disco pot at the moment and 110mph. and yes will be external gate.

    thanks for the reply mate. i was looking at either the r595 or r545 for an unopened sr on 98 with around 18-20psi down its throat. i like the 59/59 r595 wheel match a bit better than the 54/59 r545, but it would be fairly laggy id imagine.

    awesome! ive been keeping an eye on these, youre right about data being thin on the ground. really good results too. what were the other cars and model of mp that 'just worked'?

    yeh i know the front pipe is likely the problem, i said that i'll get it fixed in the last post (i.e a new one made up). is there any benefit of having a 3.5" front pipe, if the outlet of the dump is only 69mm ? heres a pic of the dump
  7. bj0rn

    ok guys got under it today, hks dump ID - just under 69 mm dodgy tasmanian backyard exhaust ID - 59mm plus the welds are f**ked on the inside so i guess that would choke it a bit more. ill get it fixed and retuned as soon as i can. one final question, would it be worthwhile losing one of the mufflers while i get a new front pipe made? i actually enjoy how quiet it is, but i dont really have any idea of how much power they leach.
  8. bj0rn

    the hks dump bolts to the factory exhaust flange, then after the flange it goes to 3". i agree it looks dodgey so what i'll do is unbolt the flange, take an ID reading off both the dump flange and front pipe flange and report back

    nismoid: funnily enough, its only 2.5" where the hks dump flange meets the front pipe. and its only that small for about an inch, then immediatgoes to 3 inch. it has a hollowed out cat, then two mufflers. are you sure it'd be the exhaust? heres a photo; harey: the intake has wire which stops it from flexing. im fairly positive thats not the issue.

    yeah i was thinking just simply dropping the pipes and taking it for a thrash was generally a bad idea. cheers for your help

    yes i know there are no afr's on the dyno readout, i'm pretty sure if the restriction is the exhaust and i remove it, theres a definite possibility it may go pop ?
  12. bj0rn

    ok, forgive me if this is a stupid question but would dropping the exhaust affect my afr's ? possibly lean it out quite a bit ? heres the dyno sheet
  13. well, i realise dyno's are only a means of measurement, but i'm convinced that my setup has seemingly less power than almost everybody elses thats similar, so im just trying to figure out what the restriction could possibly be. here's a list of what's been done: unopened s1 rb25det ems stinger ecu hks gt2835 pro-s 3" flexi pipe intake hose nismo 740cc injectors walbro pump hybrid cooler stock coils exhaust that goes from 2.5" to 3", 2 mufflers no cat 18psi - 315rwhp 13.1 @ 109mph on 205 rubber compression test came up as 150psi across all 6 cylinders it holds boost through to redline, and im assuming the coilpacks are working as it doesnt miss. it has a stock fuel pressure regulator. the most obvious thing i can think of is either the exhaust is restricting it, or my tuner isn't putting any timing into it? any thoughts please punt them at me cheers in advance
  14. bj0rn

    ok i've completely made an error, i hooked up the fuel pressure gauge in the wrong place. rookie mistake. it reads a 40psi at idle & 44psi (stock is 36 / 44 i think) with the vacuum hose disconnected. however, it doesnt increase with revs like it should. the dampner after the pump must be a bit f**ked as well because its not a steady flow. the needle jumps around a fair bit. i'll look for the vac line to the ecu and trace it. otherwise i'll call my tuner tomorrow and see if he can play with the ems. will report back when i find out what it is. any other ideas are more than welcome though
  15. bj0rn

    yep same conditions. im not too sure how i'd go about connecting the ems to an obd. i dont have one i dont think i have access to one either. its map sensored not afm. its running on bp98 and always has been. only started happening recently. has been tuned and was running just dandy for a few months up until the other day.
