hmmm maybe if the bypass valve is big enough you could use the lt5 blower and feed it with the turbo?!?
Fun thought. Compound boost setups never seem to perform in real life as well as they do at the dyno. My current setup is making over 4 digits and is running 151+ trap speeds in early shake down passes. Its undergoing some changes at the moment to "simplify" things and improve performance in certain areas (e.g. short times, higher boost, times to match the power, etc.). I am very intrigued by the 2650 rotor pack performance because I just like to see us Vette guys with as many options as possible. The Gen 2 V guys have shown what a well sorted PD blower can do (e.g. full weight boost only bottom to mid 9 sec 1/4's) with some hard work and dedication...and its only a 1.9L. The 2,650 is capable of so much more. Time will tell if shops can get it to perform in the real world like it should on paper.
I was only joking with the compound setup! Better like you say to get your setup working as intended rather than making things more complex. Also n2o is probably a better / simpler / easy option to supper fast spool. Be interesting to see your changes though!
totally agree with you on more options being better. Why wouldn’t you want more choice?
this kit Chris is about to release, will be the straw that breaks the camels back, with GM deciding to allow the tune on the zr1 to be cracked.
Otherwise, GM is going to be in a world of hurt, when people who want the fastest vette, see the logic in buying a z06 and spending 25 grand, including the cooling, and having a 1000whp 1000wheel torque, McLaren, bugatti, lambo, Porsche, and zr1 killer.
A simple oil cooling kit and aftermarket zr1 like nose from competition carbon, etc, will be icing on the cake.
This will cause people to walk away from ZR1 orders, and pick up a new or used z06 instead, while obtaining better interest rates, lower insurance rates, and also much larger discounts from msrp, and still saving a tremendous amount of money over the zr1.
Mark my words, zr1's will be cracked within a month of this product launching, and GM will stop interfering with zr1 through onstar to lock them up, once they have been cracked into. They will start letting it slide.
I think with the likes of Kwong and Crawford working on it the LT5 supercharger is going to be a great performer. Will be interesting to see how the Edelbrock unit will do and what Whipple can do with the Gen 5 blower. Interesting times for the aftermarket world for the LT engines!
Crawford, what sort of control is the electronic bypass going to give? Will it literally be 100% boost control? Is this going to tie into things like traction control as well? Maybe e% as well? Sounds really interesting similar to what OEMs are doing with the turbo engines as well!
Yes, my controllers will allow a boost control curve based on various types of inputs and strategies. It can also be combined with my existing traction control system that uses the stock ABS sensors (does not interfere with ABS function) and uses the stock coils for full spark control. The electronic bypass valve gives the same precise control that the electronic turbo control systems are using. Much more control versus the older vacuum type bypass valves offered.
Supposedly the Maggy 2650 fits under the Stingray hood. I wonder if the Z06 hoods are tall enough to accommodate a supercharger manifold spacer that would allow for port. Im still dumbfounded that this is even an issue. Who would buy a 2650 without ability to run port?
The Maggie does fit under a Stingray hood, a stingray hood was on the Z06 in the Magnuson SEMA booth.
While port injection was indeed considered for the TVS2650R on LT engines (it will be available for other LT platforms) the trade-off of intercooler effectiveness was deemed to be of more importance on the C7 platform with several new high power DI fuel options recently released (or pending release shortly).
Port is possible, but not with maintaining the large intercooler size and a stock hood.

Locking the GM ECUs has nothing to do with trying to prevent people from modifying their cars, hell they probably have the biggest interest in the performance aftermarket of any manufacturer.
It's completely about Cyber Security - and preventing the car from being compromised by an undesirable source.
Hopefully they will find a means to manage the cyber security side while allowing us owners to modify as desired, but for now I'll just stick with vehicles that have the older ECU

?
i will second that hess is likely correct. Time will tell... after all, hess put a limit of 1 month after crawfords release as a time limit.
Looking for more info from owners or tuners who have experience with this setup. What are the potential gains? How much additional work or modifications are needed to install the unit on a Z06, etc..
Thanks
i don’t have experience but thinking about a magnuson for my car. The fuel pumps could be your Achilles heel for what your considering. See this thread from a Calloway owner. Especially if your car is pre 2019.

I disagree. They don’t want people tuning the cars and causing mechanical issues. Then trying to hide them and have GM cover under warranty. An obvious form of fraud that’s been going on for years. Many admit to having a second ECM to put in just to take car in for warranty work 🙄

ironically, by locking people out of the ecm/ecu/cpu, whatever you want to call it... then it FORCES people to do mods to their cars that are intent on staying undetected by the cars computer (or else it would throw codes and put the car into limp mode)
When someone tunes the car, the warranty is gone. GM loves when people tune their cars, as GM is off the hook for having to pay any further bills on that car, and it also increases the odds that the cars are going to break, and people have to buy more parts or have their cars put back to stock by GM service centers who know what they are doing.
By keeping the computer locked, and not letting anyone in, people are just going to create cheated sensors, and the stock ECU/ECM/CPU is going to have no EVIDENCE the car was ever modded.
Now cars will be making MORE power and GM still has to pay the bill for warranty work as GM can't detect which cars have been modified if the customer takes the mods back off and puts back on the non-cheated stock sensors.
Point being, while you disagree with him, i disagree with you. GM loves when you void your warranty. Make no mistake.

How does the cheating sensors work again? You were working on adjusting COT thorough the O2 sensor?? Seems an answer was out of your reach?
Tuning the car is a great tool you add the mods which then the engine needs the correct tuning correct timing and AFR etc. . Not everyone wants to run around with stock restrictions in place such as the restrictive stock filter and stock exhaust
manifolds. Just why I will not be buying a C7ZR1 over a Z06 which is tunable.

Exactly! Also why the ZR1 is not tunable plus they have other new systems to protect. Real guys with mods put on them on get the professional tune and call it a day the car is mine I break it I fix it. . GM has seen everything and know how to handle false fraud claims.
the map and maf can both be cheated. One can avoid a lot of problems by keeping those sensors from reporting values above preset limits. Such cheated sensors are prevalent in the BMW and Hellcat/demon world. p0106 could be avoided with a cheated map sensor. Food for thought.
Yes i was exploring also tricking the car out of COT with a stock tune... but as you point out, that was a dead end.
A lot more than we can say for any of your posts. I can replace you with a parrot or a dell computer... memorize and repeat. When was the last time you experimented or invented or solved anything that no one else has before you?
You think the tooth fairy just drops off the good ideas, and no humans with a high enough IQ have to figure them out first? You think everyone on this planet just reads and repeats and claims that makes them intelligent?
Someone has to hit dead ends when looking for the next unnoticed unlocked door.

my comments don't include you until you show up and counter everything I say, and throw your little jabs. Then when I counter you like you counter me, you aren't used to that apparently, and you make a big deal out of it every time it seems.
