Vortech gurus. Enter... 928m impeller. Shredded :-(

Hay Johnattan,
Can you Verify your Serp and Cog Setup?
Fliudamper looks like it's 6.50 od, based on this with a 2.87 serp and a 28/32 Cog you would be spinning your Blower over 69,000rpm.
That being said, I spin my Blower to 62355rpm without any problems so far. I do drag race some, but No track or autocross. This is as hard as I'm willing to push the stock street blower.

by there own words "almost" 1200 cfm at 50k vs the one old man posted of 1400 at 55k. its not like its some brand new start up company there isnt a "being a guinea pig" you should know not many people go super charger for big power. if you have questions its best to use google, just because it might be on a different car it will still perform the same way.

That's just outside diameter of the entire pulley. You need to measure inside diameter, where the pulley actually makes contact.

Sorry for your loss. It was a beast while it lasted.
I believe the 2.87 pulley with fluidampr crank pulley puts your blower at 65,156 rpm when revving to 7400rpm. No bearing could hold that.
You're also exceeding 928m's max rpm rating for the impeller too:
"Each impeller is spin balanced to 0.006 grams/inch, and designed to operate up to 60,000 rpm"

I Understand That!
I was hoping to see Numbers Verifyed from Fliudamper.
The only place 6.125 shows up is on my350.com

i was told ID on the fluidampr is same as stock. honestly measuring from the center bottom of the pulley where the tape measure can grab the outer lip to the top outer lip its maybe 6.1 but inner diameter where the belt touches i would say it could be same as stock 5.7 ill try and get a picture

I re-did the measurement on my newly acquired Fluidampr to compare it to the same 5.75 measurement point on the stock pulley (which is where it mounts the belts) and I measured 6.125, the same as you got from Fluidampr...I'm not sure why they told me 6.25 when I called them

The V1 and V7 have a different Step up Ratio of 3.45/1 vs 3.61 of the V2 and V3
So, the V1 and V7 4.2% Slower, with the same Serp and Cog setup.
I'd start with the 3.12, that will spin the blower 59935-4.2%+=57388rpm. And see how that works for you.
The V1 Ti-Trim is rated @ 55,000rpm
The V7 YSi-Trim is rated @ 65,000rpm
What is your Fuel System Setup?

did the calculator on vortechs site for the v1 and even spinning to 7400 rpm that blower rated to 55000 rpm hits 54484.76 at 7400 rpm w the 2.87 pulley. any idea what kinda boost that blower should hit at those rpms w that pulley. i know that is a random question. im going to think it all over once i pull this blower. 3k is enough money to maybe pick up a turbo setup or atleast most of it considering i do not need a fuel setup or intercooler since mine is pretty solid along w motor.... really not sure what im gonna do but i thank you all for the information. such a good feeling to know i can turn to most of you guys when something like this happens to help me threw my questions. Tim i may be messaging you/ emailing you with some random questions later i hope you dont mind.

Who would you Believe?
There is a Formula for calculating actual Gear Diameter. It's not the overall Diameter and its not the point where it makes belt contact…… it somewhere in-between…….
If Fliudamper says 6.25, then that is what I'd use…..It's always better to over estimate Blower speed, than under estimate it…..

Damn dude.... Sorry to see this... Hope you get her back up and in action soon...
I'll be tuning for the 2.87 and 3.12 but I think I'll be running the 3.12 more just to be on the 'safer' side of things.
Good luck man.
