TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Thanks. It doesnt scare me. It's just awareness.
That looks like bearing failure. You can see where the bearings were spinning on the sleeve. It got so hot it melted the aluminum but the bolt was still in place because you can see the threads in the melted metal.

 

I just do it to make you second guess yourself while you lay in bed at night.

 

Possible to update the first post (and/or the Qwikchange thread) with this info...?

 

Working on it. I've been a combination of both busy and lazy all at the same time.

 

Taking multitasking to a new level lmfao.....ADHD?

 

Hmm. So my supercharger started making a pretty ugly noise, basically a high pitched grinding and squealing. I can't say yet that it's catastrophic or not, but it very well could be... When I opened the hood, I noticed that the lower wrap idler was actually rubbing on the supercharger pulley (there were metal filings on the intake tube just above the pulley and I saw a spark ). I guess I went too hard trying to reduce belt slip last time and adjusted that idler too much. Having re-adjusted that lower idler, it still makes the same noise.

So basically I'm worried I've done something to the bearings in the drive section. Sigh. Well I guess I was technically overdue for a rebuild anyway.

 

dammit, this is not good news.. Its a shame it just started up since you had the blower off so recently. When you going to tackle the rebuild?

 

Sorry to hear that. Hopefully its just a bearing and nothing major beyond the rebuild.

What tensioner are you running? You're also running a custom pulley wrap mod?

 

The customest.

 

While still staying sane? Oh yeah. Lol.

The most customest of custom? Lol.

 

Going to rule out the wrap idlers themselves first - it occurs to me I should specifically check those, it kind of makes sense to me that the idler bearing would fail sooner than the supercharger drive bearings. I didn't have a lot of time to do diagnostics this morning because I was on my way to work. If it is the supercharger then I'll send it away for rebuild pretty soon, I'll just put the NA manifold on so at least its driveable in the meantime.

I am still on the stock tensioner right now. I got my Roush in the mail yesterday. Originally I had ordered a Steeda, however mustangsunlimited decided they didn't want to send it and it was on backorder indefinitely.

I have two idlers to help with wrap...

 

The stock idler on the left looks like the sealed bearing grease is looking for a vacation!

 

What’s your redline set for the ucon? Stock for you would be 6.5/2.0x5500=17875 rpms @Athlaos

 

It’s set at 5675.

 

He's under 20,000 RPM for the blower, he's good to go. Lol.

 

Magnuson told me 18k max years back

 

Yeah, they lied.

17K blower RPM @Athlaos ?? Those are rookie numbers, we gotta pump those numbers up.

Lets get you spinning to the moon like those GTP and Regal GS guys with their M90's revving past 20K all day.

 

So crank pulley/supercharger pulley x redline? My M90 will be at 17k I think

 

That's exactly how you calculate it. What size pulley are you running?

 

Exactly. Well @rjbiii can tell you I've got something in the works although I've been trying to keep it a secret.
