Waste Gate Rattle Fix Options

[dh58]

What are the prices in Oz to get this fixed? My car sounds so bad at the moment with inlets + this lol.

Has anyone done it and regretted their options and wish they had done something else?

I bought rb classics because of the rattles.

I still had the rattles when I installed rbs.

When I changed boost solenoids the rattle was gone.

I still had boost in target and no signs of failing boost solenoids.

Great tip and share man.. Will check those out!

Is it just a poor design that makes these fail or what?

[Brule]

Not poor design but the design on internal waste gates always have metal on metal contact

Imo being normally open means that they see a lot of cycles compared to being normally closed. You can't really escape that.

Interesting that boost solenoids would fix waste gate rattle. What's the explanation to this?

The solenoid needs to hold vacuum open and closed. The solenoid wasn't doing it quick enough or something.

Mine was only on decel at a certain rpm.

It was night and day difference as it stopped rattling.

I found this link after Brule gave me the heads up on this issue.

I just did inlets and yeah, wow. I didn't know I had wastegate rattle before. Now you can't miss it.

Combine that with the fact that I've got a vert with BMS Cowl filters, there's nothing dampening the sound.

To top it off, the inlets & outlets broke the MHD E25 OTS tune (now unusable because it's too lean) - so I've got plenty of reason to regret the decision.

I don't regret it though, because virtual dyno confirms much quicker spool up and more power at lower boost - so I'm confident with a trebila flash the gains will offset the disadvantages.

I'm also loving the BOV noises since installation - my sleeper isn't really a sleeper any more, it turns heads on the footpath every time I change gear.

I'm hoping i just get used to the ticking. I'm not ready to spend thousands on Pure Stage 2 turbos yet.

With the extra airflow, you are using extra fuel.

The ecu compensates for this and if you are running lean its only one of three things, either your hpfp or lpfp is not keeping up or your o2 sensors are going bad.

Its definetly not your tune.

Thanks!!

Since i've been getting intermittent 'lambda probe' codes and my HPFP is what limits me from running more E content - I recon' you might be on the money there.

Time for me to talk to JD75
