Yes, My pump shaft snapped today...
But Im pretty sure it was due to me pushing the limits of adjustment on my pump. As I said, I had been messing around, and I was sure I was putting out more power than before... I had been tuning the throttle stop to get a little bit more fuel, as well as some Torque screw adjustments, and I just went a bit too far with the throttle stop and I hydrolocked the rotor... At least this is the best hypothesis so far...
Anyway, I was headed over east of the mountains, and about 10am, headed up snoqualmie pass, the thing basically rattled like hell and then died... I got a tow home, spent an hour and a half swapping on my N/A pump after I maxxed out the fuel screw... Set it up at the same spot timing wise (Best I could do with my tools) and was back on the road by 1pm.
The thing I am baffled by, is this 92 N/A pump performs right on par with my Turbo Cal before I started tuning it... I still hit 20psi, it still has *** when I get into it...
Im thinking my IP was on its way out long before I even dyno'd it, so this makes sense with my numbers being as low as they were dyno day.
Id like to get it dyno'd with this pump to see the comparison, its just too bad I didnt have time to get there today.

There is no warranty, not only was the pump used when I bought it, but I did enough screwing with it, I dont expect Ken to accept it back on warranty, it was my fault. So I have two options... Either NMB2 sells me his DB4, which would probably be prefect for my build now that we know what it puts out... Or Ken builds me a DB4... If he wont... Well I guess the end of the line for me is this JY reman'd N/A pump...
