Hey fellas!

Iam getting very little oil coming from my BPV on my vortech. Iam guessing my seals are going bad? ( I bought the kit used )

I spoke to someone from Vortech and they recommended me the " minor rebuild kit " for $380.

I was doing some searching and I thought for a little more I might as well get the ceramic thrust 65K.

.....

Do you guys have any feedback on them? anyone use them? It seems like they do a lot of superchargers.

heres a link:

Thanks for the help!!

I thought about this too. It's a good deal if you know how to do it yourself.. $550 for ceramic 65K rpm bearings and seals.

Has anyone rebuilt there own blower? are there any special tools?

The biggest problem with sending to vortech isn't the $400 to rebuild the blower, it's the 4 weeks of downtime between shipping and rebuilding. If you could do it yourself it would be done in one day.

+1! exactly. I hate the down time.
One guy locally is doing his rebuild him self and I was thinking of doing the same thing so I dont have to wait a month, like you said.

I have been inspecting the blower, doesnt look like it needs any special tools really

Chef- I think its 750 if you send the blower and $550 for the parts and do it yourself

Vas, sorry to hear.

I don't have any advice on their rebuild, but sounds pretty good tho. Yea, i defi understand if you have to spend 380 on rebuild why not little more if others are better.

Btw, anyone hear vortech V1 is discountinue?? someone told me, i don't know if that's true.

You are right

wheres Quamen??? He should be able to tell us if you need any special tools and if its doable.

cwylie's (i beleive the screen name is) old kit right?

if ur gonna run the 2.87 and theres no doubt about it, might be a good idea then to upgrade the bearings to spin higher rpm so it doesn't happen again, but prolly not needed, hope it works out for the best and soon..

Vas@Extended

iTrader: (17)

yep. I mean everything is good and he warned me b4 I bought it, Im just trying to decide what to do, ya know. I can run the blower without any " major " problems but I might as well do everything right b4 I install it.

Either just get the seals and stuff $220
get the 59K option
or the 65 K ceramic

I mean even if I keep the blower stock even with the 2.87 and 6600 rpm.. it shouldnt over spin the blower right?

What ems are you running? And stock block with 2.87 pulley?

Heres a list of mods:

none revup
- vortech v2
- GTM pulley upgrade
- UTEC
- DW 600cc
- 3.12 ( making the jump to 2.87 )
- walbro 255
- ngk 1 step colder
- nismo exhaust
- test pipes
- md 5/16

Yep stock block

Honesty if i were you. I will just a replace the seal first and get a W/M injectioin with extra money you left or save for better ems for future. For me Upgrade better blower and smaller pulley is later, once bottom line is strong then i will think about that later. That is one of reason i'm not going 2.87 untill i get a better ems, once i finish second around i go look for upgrade blower and build block.

Simple, When you have a two credit card and when one has enough limit, why would i upgrade other credit card limit that i can't/don't even use.

Just my two cents.

This is not Vortech but a supercharger rebuilder.. It might not take as long to rebuild and return as Vortech rebuilds do..Also, I am under the impression that the blower impeller blades are the weak link in the blowers RPM limit and not the bearings...Anyone confirm this?

Chef-J

iTrader: (58)

Btw, Vas, if you haven't install GTM pulley, make sure it won't rubbin the hood.

id just have it rebuild the normal way prolly, it shouldn't overspin it with the 2.87 but it is close, i beleive there is a graph showing what it is spinning at in the rpm's on here with the 2.87 on but search has been messed up..

a little confused here... I thought bad seal leaks were caused by surges not by overspinning. So if his bearings are fine (not making noises or shaft play) then I don't think spending the extra money so he can have the blower spin at a higher rpm will benefit much.

The op might want to adjust his bpv later on to prevent the seals from going bad again... flutter is bad but it sounds cool

There are a number of things that are the limitations when combined. The impeller tips are definetely one of them which is why the SC-Trim is an S-Trim with the last half inch of the impeller tips machined off.

Vortech has said before that it is a combination of the bearings and the impeller that limit it to the low 50,000rpm range. My guess would be that this is not so much a limit of the bearings in the case. I would be inclined to think that it is a combination of what rpm the impeller is balanced to and the effects on the bearings once you get to that limit. The out of balance vibrations after that threshold would be good reason for the impeller to explode and the bearings to go bad.

The 928M Impeller is balanced to operate at 60,000rpm's. However, I know that the impeller was sent to destructive spin testing and at 72,000rpm's the impeller still maintained its integrity and is in fact the one that is on my car.
