Hi my names Mark,

Just yesterday I had experienced my car having boosting problems. It would rev to 3,500rpm - 4,000rpm and usually you would feel the boost coming on strong. Yesterday it was probably boosting half as much as it should and I am only running the standard 7psi. The boost gauge seemed to be working ok. Although the heat yesterday would have played a part to it as I do not have a front mount cooler.

I waited until later in the nite although it was still a little warm but much cooler than during the day and it still wasn't boosting like it had been previously.

I am lost for ideas, what do you guys think of the problem?

Thanks Mark

Hmmm I think I am experiencing a similar problem... On recently I have noticed that when I put my foot down and the car starts to boost it used to just lauch so to speak, now I can hear what appears to be extra large sucking sounds for a short period then the power jumps in. I don't know if I am being paranoid or not but my boost guage ( standard in dash ) doesnt really seem to begoing as high either..

Is it possible I have a hole in a hose or popped a pipe off or something simple???

The other thing I have noticed also is that my oil gauge used to sit around the 4 mark pretty constantly, now it seems to vary quite often ( under acceleration and such ) between 2 and 6?

I have checked my oil and its not low or anything like that....

MrGTST,

It sounds like a boost leak to me, when you in the drive way pull the accelerator cable and listen for unusual noises, should highlight where the leak is occuring.

I think the oil gauge measures viscosity, therefore it should be higher when cold, and lower when hot.

See'ya:burnout:

      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.
