Yep it will be interesting to see what better gas will yield.
Like I mentioned, I could tell it wanted to make more.
The stock tune/setup is also held back by the knock sensor and available gas.

Great job ! I plan on a 2650 with a cam only on a 6 speed and roto fab dry only, Dont want the header heat, and dont want to give up the borla atak .

It baffles me if a Magneson is that much better, why isn't GM contracting with them and putting a 2650 on the ZL1 and selling it as a 750HP (or even 800HP) Supercar??? If the ZL1 was $20k more than my 2SS but offered 750HP (vs 455HP) I probably would have went for it... (Even though I certainly don't need the power) but I would have felt a LOT better paying $20k for an extra 300HP... (And I really like the look of the ZL1)... It's great to see what the aftermarket can do (albeit voiding the powertrain warranty), it is a damn shame GM isn't offering this out the door... It would sell... I mean an 807HP Challenger Demon Hellcat or an 800HP 6th Gen ZL1??? No competition there... A big heavy boat with a big motor or a fighter jet with the same big motor...

I’m betting that the Toohighpsi plates will alleviate the need for the cam and let you run full e85. Now time to get it and test it. From what I understand it completely relieves the high side from being pushed that hard. BTW: I love the Borla sound too.

Yep it comes down to production costs and the ability to deliver on the units.
Eaton is huge and was able to pump out the blowers. I’m not confident that they could have done the same with Magnuson. The LT5 was amazing and I definitely feel the LT4 + 2650 closes that missing gap. Luckily the Magnuson kit is a well sorted kit for the zl1/cts-v and cheaper than if you bought it from GM that way.

The platform is already traction limited at stock LT4 power levels. On the C7 ZR1 GM claims "they reached the limit of the front engine design architecture" Also the ZL1 1LE 'Ring time is already blisteringly fast..my thoughts. The Z06 couldn't be outclassed either... note the CT5-V BW is 668 HP...670 for the C8 Z06...

All very good and valid points. Besides Eaton wouldn't want to cut in on Magnuson's design since they buy the rotors from Eaton and design their existing blower around that rotor pack for specific vehicles.

I want the performance and sound of a cam, and I can run 93 octane that's good enough for me !

great read, and looking forward to my/your stage 1 build as well, did newtech dyno it at there shop as well if so what did that part of the build for the tune/dyno run you if you don't mind me asking.

JRG Motorsports in Hayward did the wrenching and dialing in the car.
Newtech did the tuning on their dyno.

Your mileage may vary on the cost of the tune.

I run my car hard and do open track days so I wanted the mid throttle and tip in to be dialed in so as not to upset the car… I was willing to pay for extra time and a lot of dyno pulls to make sure it would take a beating.
