Guest carrotts Posted September 3, 2008 Share Posted September 3, 2008 had my car dynoed at dyno demon on the wirral today and made 342bhp at the wheels, 407 at the fly and about 410 foot pound torque, basically all the curves look pretty good apart from where the turbo changes, which he said is normal. The dyno was at 0.8 bar which is the lower boost setting on the avcr, the chap who carried it out seems to think that with the spec i have, the car is running pretty much near its limit and to run the car on the higher setting (1.15 bar) might be damaging without looking at the internals, and possibly stronger or single turbo's... is this true?? by their own admission they are subaru specialists so i was a bit dubious about what was said excuse the quality, i dont have a scanner, these are photo's from my phone basically i'm after some re-assurance that the internals and the turbo's would be ok on the higher boost setting for regular use or just now and again ... who knows also he said the fuelling may need looking at... not sure if you can see it properly from the graphs heres the spec Apexi AVC-R boost control limited edition BLACK running 2 maps(0.8 bar and 1.15) Up rated fuel pump Walbro 255l/h Apexi Rev/Speed meter used as top speed de-limiter HKS FCD Standard fuel cut defencer running on setting 9 Apexi Power Intake kit/ induction filter Autobahn 88 specific FMIC Motoria stainless steel Turbo back exhaust system (TRD style) 3” Double stainless decat; Bluefame 1st de-cat with stainless flexi pipe, 2nd de-cat XS-power.

jacko Posted September 3, 2008 Share Posted September 3, 2008 (edited) Generally speaking the internals will more than fine with that sort of power and the turbos should be ok a 1.15 bar, but this obviously depends on the condition of them. Saying that, around 400bhp is the upper limit for both power and reliability on stock J-Specs Edited September 3, 2008 by jacko (see edit history) Quote Link to comment Share on other sites More sharing options...
Guest carrotts Posted September 3, 2008 Share Posted September 3, 2008 400 at the fly or wheels? Would that be ok then for a daily driver? Posted via Mobile Device Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted September 3, 2008 Share Posted September 3, 2008 Theres more power to be had out of the setup. Its the injectors ultimately that limit the power from J-specs. Quote Link to comment Share on other sites More sharing options...
Jake Posted September 3, 2008 Share Posted September 3, 2008 407bhp at stock boost, fantastic! Literally. Quote Link to comment Share on other sites More sharing options...

Homer Posted September 4, 2008 Share Posted September 4, 2008 what a joke. No offence like... It's running a fair bit less than stock boost too, so the figures are ridiculous. Did you actually pay for that? You've been over if you did.. it's the normal 'please the customer' result you'd expect from a dodgy dyno operator, we've seen it hundreds of times... Booted from tech too. Quote Link to comment Share on other sites More sharing options...
Tones Posted September 4, 2008 Share Posted September 4, 2008 Bring it to another RR, that figure is a bit ridiculous in fairness, id be expecting no more than 300-320rwhp TBH Quote Link to comment Share on other sites More sharing options...
Nic Posted September 4, 2008 Share Posted September 4, 2008 As already said 407hp (flywheel) at 0.8bar is a very exaggerated dyno result on stock J-spec turbos, you'd need to be running around 1.2bar to get close to that. Quote Link to comment Share on other sites More sharing options...

letmeshowyou Posted September 4, 2008 Share Posted September 4, 2008 id be expecting no more than 300-320rwhp TBH and even that's pretty unrealistic. Mine made 257rwhp at stock boost a long time ago. Quote Link to comment Share on other sites More sharing options...
Guest carrotts Posted September 4, 2008 Share Posted September 4, 2008 Anyone know a good rolling road round the chester area? Anyone want to hazard a guess at what power i should be aiming for at 1.15 bar? Posted via Mobile Device Quote Link to comment Share on other sites More sharing options...
Lukeyboy2k Posted September 4, 2008 Share Posted September 4, 2008 and even that's pretty unrealistic. Mine made 257rwhp at stock boost a long time ago. Mine only made about 245rwhp (~ 300fwhp) when totally standard a few months ago, although to be fair the auto box was slipping. Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 4, 2008 Share Posted September 4, 2008 Mine made around 356fwhp (1 bar) at bpu with stock j spec turbos. There was a bit more to be had from the injectors but the j spec turbos are limited to around 1.1bar unless you want then to fall apart Quote Link to comment Share on other sites More sharing options...
bolarbag Posted September 4, 2008 Share Posted September 4, 2008 Magnetic in-line fuel saver To be fair this would have added 20BHP at least!! Full lightweight Racing pulley kit x4 CDF CNC; crank, I'd maybe want to get rid of that unless you really do want to have to look at the internals;) Quote Link to comment Share on other sites More sharing options...
Guest carrotts Posted September 4, 2008 Share Posted September 4, 2008 How come? Dont they play well with standard internals? Posted via Mobile Device Quote Link to comment Share on other sites More sharing options...
bolarbag Posted September 4, 2008 Share Posted September 4, 2008 If its a CNC machinded crank pulley(as stated) then its probably not dampened, which company made them and who did you buy from? 0.2 to 0.5bhp at a push;) Quote Link to comment Share on other sites More sharing options...

Guest carrotts Posted September 4, 2008 Share Posted September 4, 2008 Back to the tubbies then... At what stage can you safely run j spec tubbies? Either boost wise or wheel horse power? Posted via Mobile Device Quote Link to comment Share on other sites More sharing options...
gaz1 Posted September 4, 2008 Share Posted September 4, 2008 Back to the tubbies then... At what stage can you safely run j spec tubbies? Either boost wise or wheel horse power? Posted via Mobile Device toyota designed them for 0.8-0.9 many people push them to 1.2 and have had no problems, some have even pushed to 1.4. its always a gamble going more than stock boost Quote Link to comment Share on other sites More sharing options...
bolarbag Posted September 4, 2008 Share Posted September 4, 2008 1.2bar, no point going above and you can't really control them much lower as the wastegates are rubbish, You obviously can go lower with a more restrictive exhaust, or a restrictor ring, or cat e.t.c, 1.2bar and a few choice mods should see you at about the 400bhp (flywheel) region with similar torque Quote Link to comment Share on other sites More sharing options...
Jake Posted September 4, 2008 Share Posted September 4, 2008 One other thing I was wondering about, Phil, How are you managing to run it at just 0.8 bar if the car is decatted with a 1.2 bar restrictor? Quote Link to comment Share on other sites More sharing options...
bolarbag Posted September 4, 2008 Share Posted September 4, 2008 The dyno was at 0.8 bar which is the lower boost setting on the avcr, the chap who carried it out seems to think that with the spec i have, the car is running pretty much near its limit and to run the car on the higher setting (1.15 bar) might be damaging without looking at the internals Its not possible, the gates will just leak - fully open Quote Link to comment Share on other sites More sharing options...
