sorry it says it supposed to increase airflow but maintain the same psi, one of the sites says it increases airflow by 50%, but look here.

Well, I'd have to say that their descriptions seem a little inaccurate. It doesn't increase air flow. It shifts the surge line to the left on a compressor MAP, as it is more efficient, but it does cost a couple psi of boost.

If you want to buy the wicked wheel/superior wheel/whatever it's called then I'd definitely suggest buying it from a site sponsor, and staying away from the Ebay ads for them.

 

Strokin, I have been told that IH used a bigger turbo on the 7.3's that were installed in the school busses. I have acces to one. Wonder if it will work?

 

ok well anyway if it does drop psi, do u notice a power loss with the WW over stock. i know it eliminates surge and sounds better but is there a difference in the way it performes? pros and cons.

 

I can't really comment on what the difference in power is or feels like. I'd imagine it'd feel a bit more sluggish.

Are you experiencing surge that you want to get rid of, or just looking at the wheel for the sound? If it's the surge, you can install an ATS housing which will cure the surge without any psi loss.

 

The turbo on the school bus is most likely the same as the van turbo, a non wastegate, 1.15 A/R exhaust housing turbo. If it's the same center section, it should work. If you can get some pictures of it, load them to your gallery, we'll be happy to take a look at it and let you know what we think.

 

JT, if I understand your post, the van turbo is different. How?

I see the non wastegate part. How does it relieve the pressure without a wastegate?

 

The only difference between a van turbo and a truck turbo is on the exhaust side of the turbo. The van turbo has a slightly larger turbine wheel, and a larger 1.15 A/R non wastegated exhaust housing. The stock truck exhaust housing is a smaller 0.84 A/R.

Due to the larger exhaust housing, it doesn't need a wastegate. The wastegate on the truck turbo housing is to bleed off excess exhaust pressure once the boost gets to a certain point. If the smaller truck housing didn't have a wastegate, the turbo would have too much backpressure, and could cause damage to the engine. However, the larger housing on the van turbo doesn't build anywhere near the backpressure of the truck turbo, so it doesn't need a wastegate to bleed off the excess pressure.

The drive pressure to boost pressure ratio on a stock truck turbo is about 2:1. So, if you've got 20 pounds of boost, you've got about 40 pounds of backpressure. But the van turbo has a ratio of about 1:1. So, the van turbo is much more efficient than the truck turbo. You'll probably see peak boost numbers go down a little bit, but you'll actually be making more power because the turbo is more efficient, since the engine is not having to work as hard to push the exhaust gasses out and through the turbo.

 

I was looking for th is exact info, mostly about installing the WW/Banks. if it looses power them I'm NOT going for it. Im not alieviating surge, im looking for more cost effective power and MPG. The buss/van option sounds nice. Anyone know of a posting anywhere that it was done in with before and after numbers/info?

Thanks,

i dont think the T444E has a larger exhaust housing. (maybe) on the higher Hp models. however most of them are used for delivery and busses and they need to spool quick. here is a picture, it isn't a drop in installation

 

It looks like it is painted Ford Blue and I have to put up with that terrible looking gray that they have been using for the past 15 or so years.

 

Does the Banks turbo housing (Quik Turbo or whatever it's called) work better with the banks/ww than stock? I can get a Banks turbo and wheel for a song out of a wrecked F-250 (just installed before the crash) but if it won't make much difference I'll just stick with doing the WW.

 

The Banks housing is for the turbine (exhaust) side, as opposed to something like an ATS housing which is for the compressor side. The Banks housing plus wicked wheel together should take care of any surging... yeah if going that route I'd do both together.

I should further say that what I mean is that the banks housing OR wicked wheel alone probably won't take care of surge altogether.... however, the two in combination WILL. Or, an ATS housing. Banks housing plus wicked wheel may have slightly less boost then banks housing and stock wheel, but it will do a better job of handling surge.

 

it sounds like the the thing to do is buy a van turbo!!!! is this a bolt on mod or is their much fabrication? van turbo sounds like the complete solution

 

I looked on thier website and couldn't find any info on the turbo.
