Good morning all,


My current set up is an LS3 with an an LSA blower strapped to the top of it. I'm at just under 10 pounds of peak boost with a 2.55" upper pulley. I'm running E85 and my injector duty cycle hits about 60%, and have a DSX auxiliary pump. Car made 626hp and 600ftlb of torque. All the engine internals are stock, and it has stock cylinder heads.


What do you guys think of a blower upgrade? I like the idea of the 2650 because it's a bigger blower and theoretically more efficient. Could I expect to see any power increase at the same boost level? I like the additional overhead space that this blower gives in case I want to turn up the boost down the road.



All in all, its just a higher quality blower than the stock LSA, and I feel like it would be a good replacement.


I appreciate any opinions and input.


Thanks!
Jake
