Talk to Carl. They did the super vortech upgrade on mine.

Looking at those pictures and based on what Vortech said, I'd be really pissed at the person you bought it from... If I recall right, there's literally a yellowish-orange tag on the shipping plug that says "remove me". I'm sorry about your bad fortune.

A V3 with the Si impeller and the 928 bearings seems to be the ideal setup for the blower. The Si impeller flows a little better and the 928 bearings allow you to overspin it.

Good luck!

Hey Chernandezz22. I can get you a new blower if you need one. It will be an upgrade from what you currently have also. PM me for pricing.

You know what the funny thing is. When my blower was blowing a lot of oil out of the vent plug (3.47 jackshaft/2.85 sc pulley). I called vortech and talked to one of their engineers who said that they've seen guys run their blowers with the shipping plug in with no issues. I didn't want to take the chance so I installed a 3.00 sc pulley instead.

I stand corrected haha.

I personally wouldn't want to run with the plug in since when the oil heats up and pressure builds, it has nowhere to go. I think this puts more pressure on components that weren't necessarily meant to see that pressure. My 2 cents.

I've been talking to Carl. He asked about the condition on the shafts since 928 can't get replacement shafts. Then after talking with Vortech, they gave me the bad news that they are also damaged.. :(
Apparently the pulley was changed at some point and then changed back to the original one since there's a missing seal on the pulley bolt according to Vortech. The previous owner apparently doesn't have any receipts of the work done so I'm not sure who has worked on what. Attachment 142064

PM Topgunz per his above post. He'll work with you on getting you a new blower.

According to the vortech engineer I talked to, there is very little pressure build up. I wasn't willing to take the risk either. I did think about fabricating a pressure gauge set up that would screw into the vent port to see what kind of internal pressure the blower does produce but I never followed up.

Yes we just sent each other a PM. Thanks everyone. Once this is all resolved and I get a new blower installed, what should the next steps be? Should I head over to SpecialtyZ and get it looked over? Not sure what would be a good starting point after this.

You can never go wrong with Specialty Z. It probably wouldn't hurt to have them look it over and then tune it. Better make an appointment now. I'm not sure how busy they are right now but there's usually about a 2 month wait.

My V3 ate its own oil slinger. Bits of the slinger forge weeded themselves to the inspiration shaft gear. First I thought it was just bearings that were shot since I’m overspinning. 3.47 jackshaft and 2.95 s/c pulley. Apparently the factory vortech oil slinger is prone to failure.. 928 offers a high speed oil slinger that can take the abuse-see last picture. Anyways I used a jewelers file to get all the bits off. Put back together. And it sounds like garbage. No metal in oil no abnormal power loss just sounds like crap.

With that setup you are overspinning by 10,000rpms. That is pretty rough on things as 928 doesnt fully understand how these work.

The biggest problem with highly overspinning the unit is that the oil is not designed for this. It aerates and becomes "whipped" inside. This then creates a ton of heat and the oil cannot properly cool down the unit. So no matter what material 928 states they can put in there you will always have problems with spinning it that fast.

There is no warranty with 928. I have seen impellers blow apart from them. I have seen head units only run for 1000 miles from them.

Stay with the V3 Si and keep your warranty.

You are pulling in 15psi with that highly restrictive KN filter from my old kits. My new velocity intake can make close to that (14psi) while spinning it at safe levels and im guessing at least 17-18psi if overspinning by 10k.

The factory oil slinger is prone to failure regardless of how fast the blower is spinning. Not to say that couldn't have contributed to your issue.

Aaron is correct about the oil aerating and not lubricating properly. That was verified with vortech. Fortunately, mine never had that issue, maybe due to the ceramic bearings I had installed.

My 928 impeller had a vane break off and the sc ate it. I haven't opened it up yet to find what damage it did, but it's noisy as hell too. I'm hoping it's rebuildable. Carl at 928 was sent pictures of the impeller and he never accepted responsibilty, he just told me not to run it anymore (no sh1t Carl). I'll never do business with 928 again.

It sounds to me like your bearings are bad, I've seen where oil slingers have failed and metal particals have gotten into the bearings.

If you want to overspin the sc like I was doing also, go to the V2 H/D Ti like Aaron recommended to me. It has heavy duty bearings and although it's rated 52000rpm, vortech verified it can be spun at 60000 with no issues. It's also external oil fed so you won't have the aeration issues that the V3 has.

Edit: The V3 oil slinger isn't prone to failure as I stated above. They have been known to fail.

My apologies, but I'm having a little difficulty understanding what you meant here.

I've heard of them failing but they aren't prone to failure (they don't fail on a regular basis). It's not like there's a defect in them and that causes them to fail.
