The Wicked Wheel is the exact same compressor wheel that comes on the early 99 truck. However, it is not more efficient, in fact it's more of the opposite. If you look at the compressor wheel of a 99.5 and up, every blade of the wheel is equal length. The WW is different, where every other blade is basically half length. The WW actually pushes less air, and typically when people install it they see a small drop in peak boost. The reason that folks install that wheel is because it helps cure most surge issues, not to gain power or boost.

I'm about to put one in my truck. Here's what it looks like:
However, I'm seeing plenty of boost (I've gotten up to almost 30psi), so a little less boost won't bother me. The surge going away and the extra whistle are my justifications...

Pocket, I am not trying argue with you necessarily, but according to Dieselsite.com the wicked wheel increases airflow.
that's from their description page located at:
http://www.dieselsite.com/index.asp?...PROD&ProdID=47
Now I realize that it is an advertisement and that sometimes there is a bit of promising the moon going on but that description says that there is an increase in airflow.

while towing with the WW this past weekend before i blew a brake line. I noticed no loss of max boost both stock wheel and WW were right at 18-19 psi. That is with no extra fuel mods. just whats in the sig. and my factory cut off exhaust.

The reason it actually moves more air, is with an free flowing intake system and large exhaust the stock wheel pushes more air than the housing can let through smoothly. The air bottlenecks like people merging into rush hour traffic. By pushing less air, it flows through more smoothly and doesn't try to push back thus increasing flow. By reducing friction, the temperature is also reduced.
lower air temp = more air in the same space = increased air flow
My '01 lost a little low end but gained middle and upper end power. The powerband is much more consistent and perfect for what I do which is tow. I did the intake, exhaust & wicked wheel more for longevity than for hod rodding. I want to get every mile I can out of the engine.
That's the condensed version and I'm sure there will be someone that chimes in with a more thorough explanation. I have to run.

The WW and "early wheel" are one and the same, Rick.
I don't feel like going out and pulling my intake -- doesn't the stock wheel have 6 large vanes, where this one has 5 large & 5 small vanes?? I can't recall for the life of me...

That is a nice looking wheel you have there Joe... 
Here it is.. the more vanes you have, the more airflow you'll have. The reason the WW reduces surge, is because it reduces performance actually. It's vane pitch and location is different from the stock wheel to move the surge point further to the left... it just moves the point where you can get surge, at the cost of airflow. If it drops the boost 2-3 psi, then HOW does it increase airflow? It actually lowers it, unlike what the "appealing" ads on the internet say. The WW is 5 tall and 5 short vanes, the stock wheel is 9 vanes all the same height.

Dang, there are THAT many on the stock wheel?? I never counted, but for some reason, I didn't think there were that many... I trust you -- you ought to friggin' know!!!
...and I guess *I'll* know in a few days. My daughter said she'd help me out this weekend. Should be fun!!
BTW, somebody was asking about you in another thread. Forget which one though.
