OEM goals met. I don't think they were that concerned about what the aftermarket could or couldn't do with the blower once it left the factory.



They couldn't have stuck the LT5 in the ZL1 "in the first place" because the LT5 didn't debut in the ZR1 until after the 6th gen ZL1 had been in production for a couple of years. Plus, they weren't going to put the halo of all halo GM engines (LT5) in a Camaro in 2017 and not the Z06. I don't blame them for saving room for a ZR1. There is a pecking order and the ZR1 is on top. Camaro has an advantage in that the good stuff from the Corvette trickles down. e.g. LT1, LT4, etc., which I'm thankful for. There's also the economy of scales also with sharing the engine blocks with the V8 trucks.

The ZL1 and top dog at the time C7 Z06 co-existed for a couple of years with the same power ratings, so they didn't really sand bag it alongside the Z06. And the ZL1 is currently the most powerful GM product (until the C8 Z06 comes out with an extra 20 hp), and tied for the 2nd most powerful of all time.

Wrong. The current CTV5 Blackwing has more HP than the ZL1.
