Attention: TDR Forum Junkies 
1st Sorry this is kinda off topic. Should we start a different thread?
BRANDON, We have a few different (new this year) Turbine wheels and Exhaust housings that we can use depending on your needs. In Very General terms for Sled Pulling and some Drag racing we now offer Bigger Turbine wheels and Exhaust housings that will mate to the B-1's bearing housings. The end result is lower Drive pressures at higher HP levels. Most of them still use the same B-1 Compressor wheel and Cover combination. Although we now have a few different B-1 Compressors that are used in specific applications like the Towing Rig that spends most of its time draggin a trailer around maybe in the mountains. And one for the KSB-1B-03 Turbo that is a direct drop in for the 2003/04 trucks. There is also the (censored) (B-1 Bomber turbo variant) that I won't say much about other than I think it will be the upper size limit of the B-1 Turbo line.
We are still looking for ways to improve any of the turbos. I am currently testing a variation of the Standard B-1 Housing that spools almost as fast as the "KwikSpool" B-1 Housing ... . But is 14% larger in Volume... ... . (14% difference is like switching from a 14cm2 housing to a 12cm2 on a HX35 when comparing Low end Lag. )
I kinda screwed up the housing during my mods but it shows enough increase in low end performance that I may blow another $500 for another one and let a professional machinest build in my mods. I hope to get this one down to low elevation and see how it compares to a Std B-1 housing at the higher boost levels before spending more $$$ in that direction.
It keeps delaying my KSB-1B-Ex4 / B-2 KwikKurt Kompounds
that I have been trying to get out of my head and into my truck. I currently am using the B-2 on my front counter as a place to stick post-it Notes and phone messages so that it reminds me my Injectors will be here soon.
I am Having Way to Much FUN!!!!

... ... . I do know that the first ones we did this summer did not change back and last I heard are still happy. If someone does not get the Performance results I tell them they can expect I will buy and or Change it back. Thanks Kurt
Bottom line is I have not found a hill that with my trailer i couldn't climb better with the 35 on compared to my standard B1. Empty or lightly loaded is a different story. All kinds of people tell me that it just doesn't make sense, but i would be happy to take anyone for a ride with the same load same hill same day with both turbos and show them the difference.
