GM could have used the 2300!

Then when you flip the blower over you can see the issue with cylinders 7-8 on the pre 2017 blower. The intercoolers stop short. 1-6 draw air right from the intercooler
7-8 draw from a pocket behind the intercoolers.
Thus 7-8 get a less cooler air charge. They fixed the issue on the 2017's by tilting the intercoolers so all the cylinders draw the same air from the intercoolers and adding the taller lid adding more room to draw air from.

Well clearly GM need to sack all their automotive engineers and employ corvette forum People Instead! I'm sure 'we' would have no trouble designing a powertrain to meet the power, emission, econmy and cost constraints that the current lot do!...

The tool is you! All you do on this forum is troll the threads with nothing to add but personal attacks, To try cover up for your total of knowledge. No need to worry if your right or not we know your lost
around a Corvette and have no idea. .
Your such a huge a tool you chime again thinking someone was talking to you!

Thanks! But seems you are not the one to talking about growing up.
My 2006Z06 2008 C6 2009 ZR1 2015 Z06 and 2017 z06 were all bought on the forum. Plus 5 blower kits and 4-5 sets of headers, and wheels and tires. Plus a lot more stuff you no way match my purchases here. PFFF to yourself! Plus I had a couple other Corvettes not bought here!
Great to everyone supporting the forum!

No not at all the short lid was dropped in 2016. 2017 and up 1.7's get the tall lid.

Did any of these changes add to any significant improvement in performance whatsoever? I know things sound good on paper but are there any real world performance gains. GM did not change the HP/TQ rating for the engine, or change any advertising claims at all. It was a change in the cooling and SC for the ZR1 that got all the press, not a lid for the 2017+. I am just asking if there were track (drag or road course) improvements. I did change my lid from the 16 to 17 but also did a comprehensive cooling modification as I added a larger HX and expansion tank as well. I cant say the lid in and of itself did anything. I remember back someone saying that they saw a few HP improvement but was that increase noted at the track.

The real reason I can see is that the back two cylinders where not getting the air flow of the other cylinders. This was solved in the 2017 model by tilinting the bricks (that are the same length as far as I have seen) to give more plenum volume post intercooler bricks and thus more even airflow. It's has nothing to do with cooling more just getting the air into the rear most holes!

I think it was more for endurance of the cooling system. Lean on 7-8 was maybe causing heat issues more than anything. The 2015-16's seem just as fast and the same power. The blowers put out the same CFM of air. They were trying to improve the delivery as in consistence In the IAT's.
Remember the total CFM and thus power is dictated buy the blower rpm. You could stick the supercharger on a full race 427 LT engine and it would make roughly the same power (assuming similar comp ratios, timing, etc).
