Where did i say a contoured wheel 2.6 charger will keep up with an 80mm?
Say what you want behind our backs Dan, we have flow sheets, do you?

No, I don't, your saying a contoured 2.6 wheel will flow 110lb/min
and an 80mm flows 120lb/min. How is that not saying your contoured 2.6 wheel will flow with an 80?

That is the question I want answered. I sent you a PM if you want to turn this into a mud slinging thing we can. If talking behind your back is telling people to ask for specifics when they buy a charger a bad thing, then I am doing a bad thing.
I am sorry but "it has some tweaks on the turbine wheel" doesn't cut it as a custom turbo.

We can sling mud if you want. This all started over you posting up about using a bushed 80mm wheel not working, and the question was asked for proof that it doesn't.

Chris has my number if you would like to discuss what has been said feel free to call it. If someone asks for my advice I give it, and every person that I recall I have talked to said that you will probably make it right, but there are other options available.
 
A contoured wheel has its place and it is to fit in a rule package that doesn't allow bushings/welded covers.
 
A bigger wheel helps alot IMHO. I have tested with a bushing. Power loss from running without the bushing is was not funny. As there was very little. I have never tried to bush down to 2.6" though. I have a 2.6" stepped cover I made up but I have never ran it. Bushing from 3.0" to 2.8" showed almost no power loss. It did effect spool up. CDS told me years ago that you good bushing as far as .250 down. From there down it is not worth while. I would like to try my 2.6" cover some time and see what happens but I really have no desire to run in te 2.6" class. Just something I made up to test and if some 2.6"er got mouthy.
 
So then... who actually makes chargers set up with these housings then? Or do you have to basically build it yourself?

About any machine shop can weld in a slug and turn it back down. Your not going into the compressor wheel, so you just need to make sure you meet the clearance to the wheel for the rules.
 
Your better off to step the wheel, lower the vent down into the step and bump the map grove up in height.
 
my would you need it welded up and turned down??? everyone that I have got or seen from ED have been just turned to fit the bigger wheel and they still had plenty off meat left on them.
 
just start with the standard cast cover and mill it to fit... unless you are making an existing 2.8 or 3.0 cover fit a 2.6 class then zstroken's method would work.

If your starting with a 3.0 and want it to convert it to a 2.6 slug rejector, just get the 2.6 piece welded up and then turn it back down so you don't see the welds. If your starting with a new charger, you can get it turned machined anyway you want.

I was curious if anyone knew of a company making true 2.6 compressor housings for the s400

Head is off after half a 30 pack. haha not bad at all, # 1 and #5 cyl each had an exhaust valve seat wopper jawed... So its being fixed now and i hope to be at brown county pulling.

Ill talk to Scott tonight at the franklin pulls..
 
yeah to further the point of bushed turbo's I made almost 700 with a 3.0 charger not very much but not bad for a stock 180 pump with full cuts and thats about it...lol then put in a 2.8 plug made 11 less hp...
