Wicked Wheel VS.

[sevenmalards]

Okay,
I'm THINKING about a wicked wheel for my 99.5 PSD. My delima is I know they came factory with the earlier PSD, but they stopped using them. Why? Is the factory wheel I have better than a wicked wheel? Can you guys shed some light as to why they stopped using them if they were using them in the earlier PSD?

Im not sure why they went to a difrent compressor wheel but i do know the whicked wheel will fix allot of the surging problems with the 99.5+ trucks im not sure if it builds more boost or not?

They changed partly because people complained about noise. But that wheel does help eliminate surge

[sevenmalards]

Why would anyone complain about the sweet sound of a whistling wheel?

It pushes less air, so it's a step backwards. The right solution for surge is not to lessen the amount of air with a less efficient wheel: the right way is to get a new turbo housing (e.g. ATS) or get a better turbo.

I got the ATS housing - increases the diameter of the intake to 4" from 3", with a ported housing, and works like charm. . .

But remember that you are halfway to buying a new turbo when you do that. ..

another option is to get a surplus turbo from a van - they also take care of the surge issue.

and it whistles nice just like you want ;-)

I changed to the WW not to long ago, the sound is much better for sure, I noticed no changes at all in max boost, and surging was never an issue for me before or after the WW.

If you can do it yourself, I say it's worth doing considering the small cost of the WW itself, usually about $70-$80 or so. I got mine from another member here for $50.00 and had a bunch of drunk guys put it on at Rodslingers house, so my investment was minimal.

The ATS housing would be a better deal for sure, but IMHO it's not apples to apples, due to the cost. But at the same time, it depends on your reason for considering the WW. If you have surge, it will help, it will also sing real loud, which is pretty cool, while overall it does not seem to effect boost levels, it does seem to change the boost curve a bit, at least thats my perception in my rig. I'm other WW guys will chime in with some opinions as well.

The biggest reason from what all I have heard and read is due to noise. The early 99 also did not have any sound dampening material on the tubes. So, I am sure is sang a lot louder.

[sevenmalards]

I just want it for the noise

[Ditty]

The WW will sing all day long, AND get rid of most, if not all of your surge. It killed all my surge with the addition of a larger exhaust housing.

Yes, the reason for the change was the noise for the most part. The 99.5+ wheel is a little more efficient (other than the surge) over the WW...but loosing, say, 10-15hp is better than getting that surge that is stopping the acceleration. Just my $0.02!

LOL why would you want a noisy turbo??? mines annoying LOL
