Stillen Supercharger reliabiity

Lunar-Eclipse · 09-04-2016, 12:17 AM

I thought this would be a good place to add my two cents. I just got my car back about a week ago after having the Stillen supercharger rebuilt.

About a month ago I started noticing the supercharger was getting louder. Since I had changed the oil about 1500 miles back I knew that wasn't the issue. But I checked everything anyway. Oil was clean and level was spot on. Belts looked okay. The pulleys didn't seem to have any wobble, etc. I wrote it off to my OCD and my imagination until about a week later where it went from slightly louder to what sounded like metal rubbing against metal. I determined the noise was coming from the supercharger itself and not the pulleys.

I parked it and took it to the shop that had installed the kit a few years prior. They confirmed by suspicions. They suspected one or more of the internal bearings were going bad. I had researched rebuild options before taking it to the local shop and their rebuild estimates where higher so I had them send the supercharger to 928 Motorsports to do the job. I called 928 beforehand and found them very knowledgeable. I did their standard rebuild. Their 1 week turn around time and rebuild cost were spot on. No surprises. I got the car back a little over a week ago and it runs like new. It may be my imagination but the supercharger feels better than new. I swear it's pumping out more power. But I haven't dynoed it to confirm.

Anyone upgrade the coolant reservoir? I'm on my 2nd yellow cap they keep cracking for some reason. Anyone else having this issue? 2nd one in a year.

Ha, thought it was just me. I had my first one crack during a dyno run. And Stillen will replace it, but on your dime of course. (Same with the temp sensor wire extender. When mine went bad, was on my dime)

Get the A2A kit and toss the reservoir to the side.

Anyone get an aluminum reservoir and make it fit?

Yeah high flow cats will have a meltdown even sooner than OEM cats.

You can however weld in a metal substrate in the pipe ahead if the cats to absorb some heat before the cats do
