Super B Special - 64/92mm compressor with a 0.53AR cover 71/80mm turbine with 0.80AR turbine housing
Please don't tell me that I know more about the turbochargers your company sells than you do.

performance wise were talking correct? seat of the pants ahuling 20000lb camper??
maybe so. i havent tried anything else.
what would be the comparable diff between a stock one and the super b a/r wise . given the size diffs
im not bustin b*lls here..just pickin yer brain

I think he was just putting close to the measurements that all the mass producing company's are selling now. Seems like fewer people know and understand what the a/r really is and means. A a/r of .5 can mean so much more than just 12cm or 16cm. A/R, for those that don't know, is just a ratio. An a/r is not a set housing size. Think of it as 2/3 = 4/6 or 1/2 = 4/8. The ratio is the same, but the variables that make up that ratio can be different. For some reason, I can't get out exactly what I'm trying to say, but the equations or ratios above pretty much say it for me. When my brain feels like getting back on track to where I could half way explain something, I'll try to get back on here and explain it, unless someone else has their head screwed on straight today.

4.10's make all the difference in the world when towing.

A/R ratio has to do with the flow into/out of the housings and doesn't have anything to do with the nozzle size as far as I remember. For the same size nozzle (12-14 cm) you can have different A/R numbers for the housing as it describes the scroll geometry with relation to the wheel diameter. Correct me if I'm wrong..

Thanks for the diagram. Shows exactly what it is. My wording was off. I knew what I wanted to say, just didnt say it the way it should have been said.

With the Super B they use the extended tip compressor wheel. These chargers are measured with the a/r ratio. Also everyone seems to be so hung up on the wheel size. Flow characteristics are what you really need to know. I have seen maps that show a 57mm wheel out flowing a 62mm wheel. That being said you would be looking at a close to a 57/14 and a 62/14.
The turbo will cool when towing as long as you don't lug it down. At 450 in a 12v you can get it hot, depending on how you drive it. The 24v is a little more forgiving.
The Super B turbo will flow 850cfm and the Special is 1160cfm. The Super B Special is a turbo that likes to be worked hard. It isn't a great towing turbo. It will have some lag when towing, but it wasn't designed to be a towing turbo. Hope this clears a bit up.

He was talking about the Super B Special not being a good towing turbo, not the Super B. He said the Super B was a good towing turbo.

Thanks guys. Yes there are two different turbos that I had referred to there. The Super B is a GREAT towing turbo. You still have excellent throttle response and lots of air to keep the egts down when towing. The Super B Special is a turbo that was designed for the hot rodder that had some pretty good power and didn't want to step into the twins.
