so im kinda worried about how the unit sound. it runs fine good power no problems what so ever but it has a wierd sound! its kinda like a whinning noise. and i have a belt slipping somewhere that i cant figure out btw!! http://www.youtube.com/watch?v=mHJiGMJPuAs

 

Oh crap that sounds fatal...

I think your blower is in need for a FULL rebuild...not just the bearings and seals but also the gears...

That's what I had to get done to my blower when I sent it back to Vortech, becuase it started making this sound:

Sound familiar?

 

damn..... well it sounds almost the same!!! so now i say F-it!! just bought the 928 impeller and rebuild kit!!!! cant wait!

 

Well...that might help...but I have a feeling you may have to change your gears as well, and only Vortech can do that...

BTW, I have the 928 Impeller on my current blower and I highly recommend it

 

u think so? y? i talked to the guy at 928 and he told me he has never seen the gears go bad inside any vortech. so i hope is right! i let him listen to the car over the phone and he deff said bearings are shot so ya. u notice any power gains just w/ the impeller?

 

You talked to Carl huh? Great guy...

Well, for your sake I hope the gears aren't involved...

As for the gains on my setup, here's my thread, but it was coupled with a built engine and other mods...

However this guy below did just an impeller change, and he did got some gains...

I don't see how the gears could go bad. My blower sounds kinda loud...not the same as the videos but similar. It's always sounded like this though and I think it sounds fine so I'll leave mine intact for the moment.

 

BTW, this is that same blower from my video above after I got it repaired by Vortech (This is not my 928 impeller blower)

damn huge difference! btw where did u get that filter?

 

I upgraded to the 928 impeller and noticed a 40whp gain. I think you will be happy sending it out to 928 Motorsports for a rebuild and upgrade. Their turn around time is pretty fast too unlike Vortech.

 

my repairs from vortech as never more than 10 days door to door turn around from the east coast.

 

Mine sounds more like this one than the one in the other videos so I'm happy....lol.

 

Those are K&N filter RX 4140 I think...I don't use them anymore since my bigger radiator won't fit with them...i can sell you mine for cheap if you want

 

so look what i just got in the mail!!! notice a difference? oh ya time to get busy rebuilding the super charger!!!

 

Congrats on your new impeller. You're going to be glad you did it.

 

Sweet, can I ask how much was it to get it rebuilt by either Vortech or 928? Is it possible to purchase the parts yourself and do it?

 

ya i just called 928 up and ordered the rebuild kit plus the impeller. 3 days later i had a box at my door step w/ everything in there. great service!!

 

I just sent my blower back to Vortech and they told me 3-4 week turn around. It sucks it broke on the ride home from the dyno its a brand new V-3 unit and it sound just the bad ones in these video's. Has anybody put one of thes 928 impeller's into a V-3 Unit?

 

It shouldn't make a difference...the 928 should work in a V3 just fine...
