i lost my t/spool sound the other week,while playing with my vacuum lines,i swapped some around and found what ever i did it made my bov sound louder,but lost my spool sound,after changing over,it came back,so i found out that a change in the pressure can do wonders. Didnt notice change in power,turb still spooled over, not sure what damage etc in long run could have done,but it works how its supposed to so thats all im worried bout now

the only way a vaccum line can alter the spool sound is if it is making the wastegate stay open instead of closing (so exhaust air isn't making the turbo spool), and if that was the case you wouldn't have boost.

i'm guessing your spooling noise possibly isn't actually your spooling noise but a leak (such as bov not closing 100%) especially if what you did made the bov louder (you probably made the bov close properly).

what pod filter are you using?

hi mate thnks for the reply

its got no pod filter

one more question thing they say its a faulty turbo so is it ok if keep driving the r32 ? or is there any option to remove the turbo and drive it without the turbo like non turbo or fit a new non turbo engine in the car

Hey mate don't listen to all the people putting you down.

Just take your working/stuffed turbo off and fit one of these suckers!!

1. Improved fuel economy

2. Instant increase in engine power?

3. Reduction in carbon accumulation to your engine

4.Minimized air pollution

5.Enhanced throttle response and acceleration

6.Easy to install,DIY.

Super Spiral Turbo Ventilator creates a vortex air flow to imporve air & fuel mixture? enhancing your engine's performance.It reduces the carbon accumulation in the engine and substantially increases the horsepower to your engine.

Super Spiral Turbo Ventilator blades are made of advanced precision bearing technology (running up to 30,000RPM). Yep The blades are made out of bearing technology!!

Aluminum alloy gravity diecasting design is not only anti-rust, but also has the ability to match your high-revving engine. The blades have special angles to promote extra air flow to the inlet manifold and assist in providing better engine combustion. Experience strong torque during low to medium RPM ranges but also extreme horsepower at higher engine revolutions.

Furthermore, it is environment friendly and greatly increases performance efficiency.

The products can be installed to gasoline & diesel cars, as long as there is

the inlet pipe on the air inlet of the throttle.

HAHAHAHAHA!!!!!!!!!

    • Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.
    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
