You are talking 120 hp more vs Luhns deal (13 psi) using the Vortech Supercharger, (you don't say the Model Number) the question is how did you make 120 more than a actual dyno test??? Vortech said the "T-Trim Supercharger was good for 820 HP max.

I am using a Dynosim5 software. I’ll post actual when it’s run on a real Dyno. Mine is a 400 block with 3” main 4.21” stroke and 4.151” bore so it will be 455 cubic inch. 6.8 aluminum rods, custom pistons for 9.5:1 compression. 80 cc Kauffman High Ports with Hyd Roller

The TorqStorm supercharger is a 1250 cfm blower so I chose a Vortech of similar size to simulate. The Vortech I found in the program V3-Si. Tom it’s a pipe dream when using software. I in no way would say my data is better than actual Dyno data.
