Ok so right now magnacharger is not offering for the z06 heads. Well hopefully the make it bolt in deal sooner or later
The LT4 heads do need to be drilled/tapped for the LT1 bolt pattern. This was a very simple task.
I will get our data posted today guys. I apologize for the delay, just been busy with SEMA prep and a hefty backlog in the shop. To answer one of your questions, the test car produced low 700s to the tires with the stock blower. Our initial plan was to install the new Magnuson on our shop C7Z, but we broke the differential the week before we were slated for testing/installation and fortunately had another client willing to offer his Z06 in place of ours while we waited on a new diff from GM.
Just look at his join date and posts. That should tell you everything. He clearly isn't a forum vendor and that's obvious by his name and the fact that he's claiming something big with no proof.
Looking forward to results. Will the diff be replaced by the time SEMA rolls around?

Right on. I know a lot are looking for bolt in deal. Edelbrick has it and I'm working on getting the whipple 2.9 going for the z06 guys. I'll see you guys at sema too. Got 15 tickets and penthouse suite at bellagio more than welcome to party with us.

Sorry didn't mean to sound so cocky. Magnuson said it was one of two kits sold, I saw that you went the nitrous route, which is opposite of us using 100% meth injection, did you guess switch to a larger crank pulley?
I apologize for my delay in getting this information posted. As I mentioned earlier in this thread our C7Z broke the differential the week before we were slated to test this Magnuson 2300. Fortunately we had another client eager to offer his C7Z for testing. The test bed was a 2015 C7 Z06 M7 fitted with our Stage IV Performance Package.

In addition to the modifications listed above this Z06 also had an Alky Control Methanol system and VR Flex Fuel Kit installed.
With our Stage IV Package (Stage I Camshaft) this Z06 produced 737RWHP/742RWTQ. Boost was 13.6psi peak and trailed to 12psi in the upper RPMs. With no other changes to the vehicle we removed the 1.7L OEM unit and installed the Magnuson 2.3L system. Power jumped to 826RWHP/753RWTQ. Boost was 15psi peak and MAINTAINED 15psi thru the entire RPM range. I am aware the additional boost is partially responsible for the increase in horsepower, but the point is the stock blower could not maintain the same boost level thru the RPM range.
IAT2s are obviously another major topic of concern with the C7Z. I am well aware that having a methanol system on the vehicle will have an effect on IAT2s, BUT we did see a considerable difference between the supercharger systems with regard to such. With the 1.7L OE unit in place and THREE back to back runs on the chassis dyno IAT2s would start off at 104* and drop to 100* at the top of the run. This was within 1* on each of the three pulls. Again boost was 13.6 psi initially while trailing to 12psi at 6800RPM. With the Magnuson 2300 we saw 87* on the hit while dropping to 84* at 6800RPM. This was at 15psi initially and maintaining 15psi thru the entire run. I realize the temps would be slightly higher without methanol, BUT the Magnuson did show a reduction in temperature Vs the OE unit.
Fitment was excellent. Install was straight forward. The only issue was drilling/tapping the cylinder heads for the LT1 intake bolt pattern. This did not prove to be challenging at all and could be done in your garage. With the blower installed the engine bay maintained a very clean and OE fit/finish. I have to say we are very impressed with the Magnuson unit and feel it will benefit a lot of combinations moving forward.
Feel free to email me at Ron@VengeanceRacing.net or post in this thread with any questions/concerns you might have. We are happy to help.

Any plans for more boost on the Magnuson? Also, why is the stock blower curve so rough compared to the smooth Magnuson curve? Is it because the blower is maxed out limiting airflow?
Great results! How close to maxing it out are you at these power/boost levels? Could we potentially see 900rwhp/800rwtq with a different cam and more boost???

The stock fuel system even with meth has to be close to its limit. Wondering what could be done with it as its pretty much un chartered territory. Hoping we see some shops tackle it. Would love to see 850-900.

The torque may have only been 10 at peak, but look how much better it carried out.
