it's extremely dodge

more than half the time, the needle will not read past 3000rpm or 3500rpm and sumtimes wen i push it hard the needle may drop down a lil, but wateva the reason, the tacho does not match the sound of the engine, sumtimes the speedo even reads 0 until a short time later, culd be a minute, culd be 5, it just jumps bak up to wat da speedo shuld be reading. i have reason to believe my whole dash is screwed.

i've been told it culd be my vacumm cables are blocked a little, or it was mucked around with before i bought the car, as it reads it's gone 22000km's, yes, i admit, it certainly must have gone further than that. how do i fix this problem?

any info wuld be greatly appreciated.

Check your hose in the engine bay and if you whip the r/h front wheel and under gaurd cover off you can trace it right into the cab. Then you can follow it up under the dash. Take the dash facia out and you can keep following it to the vacuum gauge. In the engine bay it starts at the front of the plenum on R33's.

The speedo prob. is a power thing, I'd be checking the fuses [easy] and then pulling the dash facia out and checking it all, make sure connections are good. Could cure the tacho at the same time??

i had an odd problem where my speedo would go spastic and the hicas light would flash. it was only after a certain rpm. i found the rsm RevW value when reached causes the speed to go from whatever speed to 0 and back again over and over (dance style) and hicas flashing. i had to set the RevW value to 11000rpm to get around it. very odd

my dash was similar, speedo didnt work at all, and occasionally the tacho wouldnt work either

replaced the dash on saturday and its all fixed, was either the internals of the dash or the contacts on the 3 plugs that go into the dash.

      Brake pad Compound suggestion

      By GTSBoy · Posted

      Initial/early bite is a feature of.....generic pads. Things that work cold. Just put Bendix Ultimate in it. If you don't like them, it's only $3.50 wasted and an hour to change them. I've been using Intima SR, and they seem to be a good performance pad. Street friendly and able to take at least a little beating.

      Brake pad Compound suggestion

      By Vee37 · Posted

      As I implied in my post, I have NO idea what the were. But in case I didn't make it clear, the way they performed was brilliant; whatever the brand was. I think it was the compound that made the difference. And if they were Bendix, then sign me up, I want another set. I did drive down mount Ousley (just outside of the Gong) a few times, and they showed no untowards performance.   Its not the low dust that I am looking for NOW. At the time I needed low dust, but now I have no issues with dust but want the initial/early bite of the pads that were used. Yeah, the early cold squeal may of been due to a missing shim or such.  And to repeat, its not the low dust I am seeking, its the initial bite of the pads and increase in bite as  the warmed up during each breaking. As soon as I let off, I don't remember the breaks being extra sticky if I used them again soon after. But I also did not test that theory.   Thanks for the recommendation, But I would prefer to choose something specifically with the behaviour I described.   I assume that they didn't use the default compound off the shelf, as we discussed the dust issue at length. And the early squeal when cold, I have seen the sound is more of an issue with some pad compounds. Mostly ceramic, which also are said to produce less dust.

      🚨 Need Advice! Overcharged for Engineering Report 🚨

      By MBS206 · Posted

      Well, in 2007 he must have been charging about $1800 an hour. He only looked at the car for 5 minutes. And another 4 to write the report wrong, and another minute to correct it. Mind you, this was for a car that was: Stock engine, fmic (hole in drivers guard), all alloy intake and custom air box, 3 inch turbo back exhaust, lowered, and a set of 17" Advans (255/40/17 rear and 235/45/17 front). It was nothing crazy. The blue slipper wanted the "hole in the guard" engineered. But that was because he got the shits that I wouldn't "relocate the battery from the boot, back to the factory position in the engine bay"... In an R33 GTST...     Also for emissions, E85, and don't go wild on timing. It's amazing how the closer you get ignition timing towards max torque, the last couple of degrees really throw NOx counts right up. And for the huge increase in emissions, it's only a small increase in torque.

      He'll be looking down and swearing about "the damn apprentice" for trying to convince Duncan to use percussive maintenance... 😛
