I did mention it to Carl....I am considering having him rebuild my poor YSi, I found a place selling aftermarket YSi impellers since Vortech will not sell the parts...HMMMMMM
BTW, do you know what rpm the 928 impeller runs out of efficiency? I asked Carl this question and I didn't get a clear answer from him.

You should not have to buy a new one thats crazy good luck.

Thanks...and you may want to consider the 928 pulley, the ribs are shaped to minimize slip....I don't have any slippage and I don't need to tighten the belt like a violin...
I did need to machine the pulley to fit our setup though...
And then of course there's the Reichard Racing pulleys...

again, congrats.. I love to see this sort of thing.
be different, not walk in other shadows is what I say/think/feel/do
looking up the 928 pulley now to see the diff. I have a rev up so the bracket is a tad weaker, cut outs for the cam housing. We think we are getting belt walk from the bracket flexing under high loads.
its all fun and R&D, my wife hates it, I hate it and love it at the same time!

My first trip to the tuner was a fail...my then setup was a CJM Stage 0 fuel return (still using stock lines and rails) with RC 750cc injectors and Aeromotive 340 pump, and I ran out fuel @ 5500 rpm....I also decided to switch from my PMAS Maf (I tune with Osiris) to the Uprev MAF GT, and I was maxing that out as well....I was hitting ~19psi; when I was running ~500whp my boost was about ~17 psi...
So I decided to get a Treadstone 3.5" maf tube and updated my MAF piping to get it to work....that resolved my maxing out of the MAF...for the fuel I upgraded my setup to a CJM Stage 2 (rails, hardpipe) and 1000cc ID injectors....installing the Stage 2 was fun, particularly trying to get the fuel line up from under the car to the fuel pump
...Charles from CJM was helpful in helping me with the install, and also with the fuel gremlins that continued to limit me even after the Stage 2 upgrade....I ended up also upgrading my Aeromotive 340 fuel pump to the Walbro 400 (not as hard to do as you may think, thanks Hal and Dustin @ Dynosty) and also wiring my fuel pump directly to the battery...you have to remember that supercharger setups use a significant amount of fuel more than turbo setups because of the extra work the engine has to do spinning the blowers, particulalry at higher rpm and horsepower...and I finally got it working with with fuel to spare, maybe even enough for E85 if the future....maybe
And when I finally got everything right, I got this:
Just like the previous time I went to MD Automotive for a dynojet baseline, there was major slipping issues of the dyno roller and it took multiple tries and probably and lighter footing on the gas to get an accurate reading; the guys at MD do dyno testing for edmunds, so they may not be used to higher horspower cars, I can't help but feel my torque numbers should be better (my tuner uses a dynapack, but most people don't like that sort of baseline, so I decided to also get a tried and true dynojet baseline, and my torque is somewhat closer to the whp value on that dyno since there are no roller and tire factors involved)...
I was getting about ~21 of boost, no slip whatsoever...the revup bracket and pulley setup for the vortech is truly superior...
Anyway, it nice to hit the 600whp mark, but I can't help but feel a blower as big as the YSi can get even more power, if you can manage belt slip issues....I see perhaps the 700whp threshold being broken by the YSi, but I will be happy with my setup, particularly since my IPP Stage 2 engine is only rated up to 650 whp...
Props to CJM, Dynosty, and as always Church Automotive for a great tune...
The bar has been set fellow Vortech peeps...so someone go out there at break 700whp (I'm talking to you, OldMan)

1) When did your Uprev MAF GT max out? From the above you say when you were hitting 19psi... what power level was that approx?
2) At what power level did the IDC of the 750cc start to run 100%?

1) With the Vortech, that was at about ~500-550whp DJ when the Uprev MAF GT and oem maf tube maxxed out...
2) probably at about the same whp as above....keep in mind I was running the oem fuel lines and rails at this point; that was probably the limiting factor...

Impeller Results
I love the results you have gotten from our V2 S-Trim performance impeller.
Do you think I could get before-and-after Dyno charts from you? I'd love to use them.

I understand.
With your permission, may I use your final dyno sheet in my advertisements for the impeller?
If yes, then please email it to me at carl@928motorsports.com
Much appreciated!

It was more for tuner preference...when the HPX was the only MAF out there, my tuner was able to tune it, but for him the Uprev MAF GT was much easier to tune due to the higher resolution, but since its probably only good up to ~500whp with the stock vortech MAF piping, I had to get a bigger MAF piping to use the Uprev MAF GT with my 600whp setup...(I'll document some pics of my piping setup in the near future)
So bottom line:
Uprev MAF GT: Easier to tune, better resolution, but only good to ~500whp on stock Vortech MAF piping, unless you increase MAF piping size.
HPX PMAS MAF: Not as easy to tune, not as good resolution, but good up to ~1000whp, so they say
So MAF choice would depend on your setup and power levels

Stock MAF tube piping is 2.75". Also, keep in mind that I only updated the MAF pipe and pipe with the 45 degree bend before the MAF pipe; everything else is still the stock Vortech piping. If you were to be a baller and do custom 3" piping throughout the whoe Vortech setup there may be more gains to be had...

gotcha. i've got an aps twin turbo kit, and i believe the intake pipe is 3" if not 3.5". i'm likely going to be switching over to uprev and was curious where my limit may wind up.

Ive had both in my car and id say the HPX is "better", ive hit 26psi with no issues on both MAFs, just found somr inconsistencies w the UpRev. Tried like 3 of them, lol but not lol.
I just have 3inch intake/MAF side but my blower inlet is 3.75 Ttrim, also running two bypass valves, ea side of intercooler for pressure relief of decel. Stock mini race good for 18lbs. Maybe a lb or two more wouldnt be too bad.
Stock MAF volts maxed at 5volts out around 16/17psi.

Look at shop builds or search threads started by me, its not my thread lol. Id paste a link but im.on my phone.
Before meth I made 557.7/455
Its not about one making more power per say, they both did well psi/HP/voltage wise, just frel HPX makes a better product, but more tuning effort. Tomaaato, tomahto
