Over spinning V3 Si :(
Well I have had the supercharger on my car for bout 3,500 miles with the 3.47 pulley and the 10% overdrive balancer. Been turning the engine to 6,700-6,900 rpms on occasion for the 3,500 miles. Finished making a pass at the local 1/4 mile track and was getting my time slip when I noticed the supercharger making a noise. Got it trailered back home and opened it up to see what was wrong. I talked to Vortech and A&A, and they were thinking I was over spinning it. I am deciding to upgrade or change my pulley to the 3.8, then it would be at the peak of the limit of the max rated RPMS. Oil feed Ti or the YSI, I just don't want to loose my "snappy" car. Trying to keep the power in the mid to high 7's to the lower 8's and torque where it is at 660 to 700. Now for the picture.
I was at 737/656

That just looks like you destroyed the oil slinger after it came loose. Unless you got shrapnel in the bearings from that thing falling apart, it shouldn't be such a big deal to repair.

Yes you are correct, but from what Vortech told me from pictures and talking to them, this only happens from over spinning or to much oil. It was not over full, that is why they are saying over spun. They are repairing now with new bearings, seals, and oil slinger as long as it didn't damage the shaft. Just seeing if any one else has had this happen from over spinning the supercharger or it was loose.

Well that's good to know, I was spinning it 57,268 by the calculator per vortechs web site. From the specs I have found 52,000 is max, I am having a hard time seeing over spinning it just a short period caused it to fail. From my figures it is over spinning at 6,275 to 6,900, which is only a few seconds on a 1/4 mile run. I wonder if there is an upgraded one available.

I overspun mine for almost a year with no issue. Traded it in on a V3-Ti to go with a new short block and maxed it out from the get go. Wish I would have went with a YSI (that I have now). Much easier to buy pulleys than blowers.

Hmmm interesting...
I am running a 3.33 and 10% overdrive on my si trim. Just got it back on the road a week ago and of course no issues yet. I don't turn mine quite as high shift at 6500 or so max, been shifting at 6000 lately.
I should be seeing the same 57k rpm you are at 6500ish. Mine is engine oil fed not sure if that matters. Sorry to hear about your problems keep us updated on it.

Yeah I had mine for about year and a half at the current pulley combo. Did you loose the "snappy" felling from down low when you went to the Ti or the YSI? I dont mind upgrading but dont want to keep building the driveline to keep it happy, I have already done the transmission twice and the diff once. I just bought CCW dragpack then this happened!
You have the oil feed unit and from what Andy and Vortech said they have the HD bearings, and the lack of the Oil Slinger to come off. From my understanding there has not been many failures of the oil feed units just the V3's from over spinning. I seen your setup and it looks good for sure.

Your correct that oil fed units have different bearings and have less issues being overspun.

If I were you I might just upgrade to a Ti and make upper 700s to low 800s and call it a day. Unless of course you want to grow into a ysi

It's a roll of the dice in my experience over the years. I've overspun every blower Vortech makes on cars I built at my old shop and had great luck without failures, but I've also seen guys like you loose the guts from a slinger letting go.
I usually tell guys if they want to max out or overspin a headunit to get a engine lubed version.

I have had a time with this car, getting tired of working on it all the time.

I am thinking of going YSI, but still unsure. My plans I hope to include an oil feed unit either way.

Well my car says thanks, I don't know on unit yet but plans hope to include oil feed. Ti I would max it out for sure and see what it would do, but would make more sense for the YSI.
I knew it when I pullied it with the new engine, but oh well. I will be in contact with you or Andy soon, I hope (if my wallet can handle it).

We'll take it on trade if Vortech says it's OK.

Yes they are, and have answered all my questions so far. Has anyone run the "Ti" v1, or v2 unit? I am looking at the 1400 cfm one not the 1200 cfm "T". I already have full 8 rib and the id850 injectors but don't want to upgrade injectors and do direct drive as that will bring the total price of the upgrade a lot higher.

I've had a few of my dealers max out a Ti on stock compression, stock cubes and make 800rwhp and 810 rwhp.
