Lyscholm Vs MagnaCharger
Lyscholm 2300 vs Magna Charger MP122H (soon to be released) HP is very close, but take note of the discharge temps. Remember the 2300 is a 2.3L blower and the 122 is a 2.0L blower. This dis-proves the "screw is cooler" Statement made by most of the "screw" Manufactures.
10 lbs boost on a stock 5.3 truck engine with a G2-3 Lingenfelter cam , timming was locked at 26 degrees and VP 103 was used, This test was done just a few weeks ago. As you can see the discharge temps are about 20* cooler on the 122 at 10 pounds of boost.

What device was used to read temperature for these tests?
Was this a side mount whipple? What were the intake configurations? Did the whipple have its usual 90* TB plenum?
10psi of boost could mean a vastly different CFM variance between the two configurations.

All superchargers were tested on the Magnuson Intercooled manifold. The measuring device is the temp probe supplied by Superflow for measuing intake temps. (Type K high resolution thermo couplers)

Correct, however with the lower discharge temps more timing could be added
.This test was preformed to prove or disprove the claims of lower discharge temps.

I'd love to see what the new Whipples do. Wonder if they really are better than the Lysholm ones.

those look to be very close in terms of power output with the nod going to the twin screw under those test parameters; however, it's curious that the screw's discharge temps are considerably higher from about 400hp/4000rpm on up, isn't that where these things SHOULD shine? That MP122 looks to be a very efficient piece
and on .3 less liters.
neither of these guys are slouches, that's evident.

Did magnusson create an adapter plate for the whipple compresor and run a different drive snout, but still use the Radix belt routing and brackets? I for one would like to see a picture.
