Hey guys having a problem with my car if anyone knows whats going on and can tell me your thoughts that would be great...

Ill start off by saying i just put in a boost gauge and boost controller (bleed valve) I put new heavy duty clamps on my intercooler yesturday so that I can boost my 32 without the intercooler pipe falling off all the time.. stock 7 psi i boosted it to 9psi when i got my new clutch fitted about a week ago but i wasnt thrashing it at all because the pipe fell off twice so i was taking it easy till i put in the new clamps.. so got the new clamps on so i increased the boost by 2 more PSI which shouldve made it 11 PSI but when i was running it, it was only showing 9 still.. so turned boost down to 7 and went up 4 PSI to make it 11 but now the boost gauge is showing 7 PSI... anyone know whats going on here?

Any help would be good...

thanks

if it feels like its boosting right, i'd be looking at the boost controller accuracy, and the lines going to it.

if the car feels like its not making the higher boost, then check your boost controller. the turbotech type can get stuck. the spring gets caught on the threads inside, and the ball doesnt move freely. open it up and put it back together.

i just put it back to stock then i clicked it 4 times and it worked and it was fine then i clicked it 1 more because i wanted it at 12PSI and now its stalling everytime its not in gear so i put it down 1 like it was before but still stalling alot might be a boost leak...

Anyone have an idea?

Faulty boost gauge? Get a friend who has a working one and test it out.

The car is stalling? you must have over boosted it the first time and now you have a cooler pipe leak. Recheck all the clamps and hoses, and look where the boost controler is, kinda sounds to me like one of the houses must have a hole in there, happened to me a few times

get a friend to check it out and c what happens, then again you can always go to a mechanic

hmmm. i got a bosch 040 fuel pump in there with full tank of bp ultimate.. really hard to drive now.

when i floor it in first to 5000rpm i switch to 2nd and then floor it but it doesnt feel like its really pulling at all, feels like the boost goes away... the BOV is blocked by this tube thing my mate put on, i dont think its that though, because it was fine before i put in the boost controller and gauge, heavy duty clamps and boosted it. getting it checked from my mate tomorrow, also gotta put in a new clutch master cylinder.. hopefully it gets fixed tomorrow

It should be running 10psi stock as the R32 turbos have a 10psi actuator on them so they cannot run any less boost unless you have a huge leak or something similar.

Maybe your bleeder isn't set correctly and is leaking boost or even the BOV if its not blocked correctly it will leak boost pressure, as they are designed to do.

Hook up the wastegate lines as normal and make sure you have blocked the BOV off properly then try it again.

Where did you run the line for the boost gauge from?

Worse comes to worse I will have a look for you, your just down the road.

Let me know.

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
