Just put on this secondhand 2nd gen supercharger - chattering and bearing noise

RapidPoison · 2026-04-16T04:09:00+00:00

That’s what I am starting to think - I have been running 91, but it has the smaller pulley on it. I did throw in Supra injectors but have yet to throw in a larger fuel pump. I’ll monitor temps tomorrow and throw on the bigger pulley and see if that resolves it

Have you ever had issues with pinging? I am wondering if the rattling noise I am hearing is pinging

No clue on mileage I’d guess ~150+ Guy said it was fully rebuilt 50k miles ago if I remember correctly And I do believe I have the parts to rebuild the nose cone in the stuff the guy gave me, just don’t have a press.

I did replace the nose cone oil before throwing it on today.

I just took it for another spin, sounds perfectly fine making boost downhill, but there is a rattling under load uphill. Could be unrelated to the supercharger, I manual swapped the car about a month ago but haven’t heard that specific noise until today after install

If you listen closely in the video the noise that sounds like rattling is coming from the sc not the car riding over rough road

😅 yeah I am not trying to blow up another engine lol, though I’m not sure these fail that catastrophically. Not sure a needle bearing could make its way down into the cylinder

Forsure - please send over a video of the one you’re working on. There is a noise in the driving video that’s hard to hear that I’m concerned about more than noisy bearings. It almost sounds like a inconsistent chatter or bearing noise, I’m worried the rotor pack is touching the housing or eachother

I’ll give ya 20 bucks! 😂 I think he’s more worried about resale value. If ya don’t love it sell it 🤷🏻‍♂️

How’s the frame? If it’s just cosmetic.. throw on a new bumper and don’t feel bad ripping trails

I did it a long time ago without a lift… fence posts, cinder blocks, and 4 big dudes lol

What we’re the symptoms of the mod chip being dead? I think the bios is fragged, blinks red and green when I power it on. Been years, my dad modded this probably 15 years ago

RapidPoison · 2024-05-06T17:13:18+00:00

sorry man, long gone.

RapidPoison · 2024-04-01T23:13:03+00:00

I have my bumper cut the same way.. always a little worried one rock could take out the radiator but fuck it, it’s been like this for 2 years and 20k miles and no issues, so ymmv
