This blower is 1 of 7 that Eaton made as a prototype. I believe it is very similar to the hybrid unit used on the time attack Cobalt. It has almost no miles on it (dyno testing only). The markings on it are directly from Eaton and we were instructed "not to open it or change anything on it" which is why the snout was not ground down for use with a smaller pulley.

Because Time Attack challenges involve multiple runs, the engine must be powerful and durable. The Time Attack Cobalt SS Supercharged coupes Stage 2+ Ecotec engine is certainly up to that challenge. Developed by GM Performance Division and GM Powertrain, it features an Eaton M-62 Gen 5 Hybrid supercharger and delivers 264 horsepower at 7000 rpm and 230 lb.-ft. of torque at 4000 rpm. When nitrous boost is added, performance jumps to 344 horsepower at 6800 rpm and 350 lb.-ft. of torque at 3600 rpm.
The 20 hp increase was from a straight swap of the Gen 5 M62 to the Gen 7.
He mentions the tune because it is included in the price. So with this new blower and a tune you could see 30hp-35hp more over a stock or stage 2 tune.

The housing appears to be diffent from that markings point. There is no "LSJ" printed on the blower outlet port like normal. The rotors look similar, so I can't really tell what the change is there.
I bet you would have better luck selling this blower if you took a test car and dyno'd it with the stock blower. Then you took off the stock blower and replaced it with the new one and the same pulley size was used to show the difference only a few minutes later. I highly doubt that a tune would be necessary if it'll only make 20hp more. Especially if it's a stock or stage 2 tune, the extra air would help it out while providing results of just the blower. Then you could add the tune too if you feel necessary. People just want proof of it working and that's the best way to do it other than taking it to the track. Just some food for thought.
