Doesn't Magnusson make the blower used in the Edelbrock and Callaway kits as well?

2.3L generates less heat per psi and the intercooler bricks are more efficient at removing heat from the compressed air. The intercooler housings in terms of mass are so close that any "heat sink" effect would be negligible. All compressors have an efficiency map and I've not seen one published for either factory blower with either the 1.7 or 2.3 Eaton rotors so cannot comment on efficiency range. All TVS 2.3L blowers including Magnuson and Edelbrock use the same rotors as does GM but differences can be found in the housings, intercooler bricks, inner dimensions, air pathways, lid design, outboard heat exchangers, etc..
I would like to see where you can prove your statement it generates less heat.
The 1.74 is more efficient than the 2.3.

That's such a BS statement. The cooling alone in 2.3 is much more efficient, it won't be spinning as fast as the 1.7 and still produce more power.

Not BS at all the 2.3 does take more horse power to turn you could maybe be look it up and even GM says 1.74 is more efficient than the old 2.3.

The intercooler bricks are much more efficient in the Magnuson unit. Not only that, it won't be spinning as fast as the stock supercharger. Overall this equals less heat and more efficient power.
As far as the 1.7 being more efficient than the old 2.3 from the ZR1, that's debatable. The stock unit is good, don't get me wrong, but it isn't great. It may take less power to turn and generate boost quicker since it's spinning faster, but it puts out more heat too. I think it's common knowledge in the car world that heat is bad for forced induction (power wise). The stock blower is a nice unit, but once you want more and more power, the efficiency decreases, and it happens quickly.

Everyone loves it when man comes into a car thread. While looking right in the mirror while talking about himself.
I included his picture so you guys know. Just who we are dealing with
here.
Great description S. The shoe fits and he wears it!

The TVS 1740 has a peak thermal efficiency of 71.7%
The TVS 2300 has a peak thermal efficiency of 72.3%
If you are looking for increased HP the area of interest is at the upper end of the engine's operating range.
The TVS 1740 moves 2207 kg/hr @20,000 RPM and 1.8 pressure ratio.
The TVS 2300 moves 2215 kg/hr @16,000 RPM and 1.8 pressure ratio.
The difference is that the 2300 at the point above has 8.4% higher efficiency.

The issue with the increase in power I don't feel will be with the SC, but more with the LT4 fuel system, while the TVS2300 is more than capable of delivering enough air for a large gain in power, the fuel system will be the limiting point. Hopefully getting a system on my car in the near future so I can determine exactly what that point is.

There are results but they aren't mine to share. The delay is the guy has more parts on order and is probably waiting to announce anything until they are installed too.
My advice, just be patient, no need to keep asking what's going on. The answer is nothing is going on at the moment.
