or as paul said, just turn the boost controller off... that will set it back to std boost

yeh basically just bypass the solenoid all together so instead of having actuator and plenum lines into the solenoid have the actuator line joined to the plenum line and it will run stock boost - 8psi or whatever

yeh i went to mackas to change my plugs instead. at the time i thought it was a plug issue but not to be by the way im running NGK 7's gapped at 0.85mm if anyone thinks that could be the issue?? thanks adam

yeh i dont have a timing light yeh ill put it on the dyno i may have figured out my pinging issue as well, no 6 injector isnt firing as well as the others so will run some injector cleaner through the next tank and ramp her up late next week

ok pullled the cam covers off this mornin and checked cam timing its all 100%. if it were a tooth out im sure itd be running alot worse than what it is... so for now thats ruled out its under full boost that its doing it, which makes me wonder whether its just a coincedence or that theres a boost leak or a problem with the turbo it doesnt misfire, its just really hesistant under full boost over 4K. any ideas anyone? a big thanks to those who have replied so far

im thinking more toward cam timing retarded than base timing though. cos off-boost and up to around 4000rpm it feels 'ok'. well im gunah take it back to the shop today - now i remember why workshops are shit

yeh ive been playin with the CAS, also changed the plugs but no good... i think its retarded cam timing. sound like the right symptoms?

maybe i needed to be a bit clearer, sorry i have std cam gears and cams. recently the water pump was changed and the cam belt removed in order to complete the job. since picking up the car from the garage i have absolutely no power up top and are getting some serious backfires. is this a timing issue?

nah its been like this since the water pump was replaced yeserday. (cam belt came off) so im assuming its timing of some sort...

dave; if you read this mate u reckon u could have a look at my thread in forced induction? ta

yeh i have a feelin cam timing is retarded... mainly cos the lack of power is up top problem is this is the local, family garage which i used only cos i didnt have a rattle gun cos of the crank pulley bolt. so i think theyre gunah throw their hands up and say i duno... time to get angry

had the water pump changed the other day (cam belt off) however now all my power has gone. itll spool up ok but over 4500rpm theres no power at all. i cant audibly hear pinging or misifirng. i just bought a new set of plugs and put them in today but the problem is still there im guessing its timing, do my symptoms sound like base ignition timing (CAS) or is the cam timing out?? thanks adam

afternoon paul do you know anyone with a timing light? my cars running like a pig and im guessing timing is retarded to something rediculous

ah right cos im at work in weshpool just round the corner, depending on what time i finish i might drop round n have a look why u runnin on the dyno if your engine is suspect?

what time?

dave: what was your pinging issue in the end? blocked injector?

yes, but if the exhaust wheel is too small boost will creep why u goin to the dyno tonight paul? cam gears?

aidwan; i dont think so example: a offtheshelf system like mine with that same bleed valve worked 100%

paul, please explain?

ok cool, thanks paul

im tellin ya aidwan boot control is fine, look at wastegate, or possibly exhaust wheel size... that exhaust whee may be matched to the compressor in a 2L engine, but on a 2.5L engine it cant flow the extra exhaust gas and so boost creeps up

2x 195/55/15

paul; legal - that is the only reqwuirement

maybe we should have an intervention

aidwan where u pullin your money from?! can i have some?
