Lingenfelter Supercharger package
The beauty of the Maggie is the power increase under the curve. Check out a dyno chart, look at the TQ numbers from 2K RPMs all the way up to 5K or higher. The TQ curve will be almost flat. That is why a 550 HP Maggie engine might easily outperform a 600 HP Heads/cam engine at the track. On the street it's no contest --- the Maggie will have gobs of TQ available on demand even off idle.
the Maggie is cute as hell to look at.

I believe I could get more hp out of a procharger but I love the sound of a maggie!!

and it looks sharp. Real sharp. I dont know if there is a need to start adding mods on top of that. They tune it and if you add things it will need a retune. Besides that they offer a 36000 mile warranty. Its truly
the best way to go. You can easily put 12,000 worth of mods on and
the car may not drive any better. Good luck with your decision.

You're gonna be happy!

The customer recently returned in search of more power, I then installed a new small OD pully to make 7.4 PSI of boost. This smaller pulley and more boost with additional tuning made 502hp and 501ft/lbs. While the Hp gain was only 37hp, the torque gain was huge at 66ftlbs. In my opinion to make 600rwhp will take more extensive mods on top of the blower or a forged larger displacement engine.
A better solution maybe a twin turbo setup to get closer to that 600hp power level. With turbos you don't encounter the parasitic losses from the engine having to drive a supercharger. You can easily gain 50 to 75+ hp more with turbos over a supercharger making the same six to eight PSI boost levels.
The M122 according to Magnusson or Callaway is recommended for engines having a displacement of 6.2 or larger.

While this blower can be used on a 6 liter engine, in my opinion it alone won't be enough to get you any where close to 600rwhp. You may get a little closer with a set of ported LS3 heads, and a LPE GT11 camshaft, I am thinking that you would be somewhere around 540 to 560.
At 600rwhp you are close to 700 at the flywheel. At that level, the bottom end meaning the pistons may not last long. The car I mentioned earlier is a blast to drive with over 400 ft/lbs above 2500 RPM, it is very fast with just 502hp to the wheels

Here is an engine dyno graph of a 403 CID LS2 engine that we ran an H122 blower on:

This engine had lower compression than a stock LS2 in order to run the higher boost on pump gas (around the same CR as the new LS9). We were spinning the H122 to its maximum rpm. We were also running into belt slip issues and ended up building a cogged rear belt drive for the supercharger (with a tensioner) and running a 8 rib front drive belt system.
We and others have run engine dyno tests on 122 equipped engines that have made enough power to make roughly 600 rwhp but those engines have been running open exhausts, stock or close to stock compression ratio, good fuel, close to maximum power timing and lean air-fuel mixtures (by supercharger/turbocharger standards). Even then you have to spin the 122 fairly quickly.
To make that power level you really want a TVS1900 or TVS2300 (the new four lobe, higher efficiency, higher flow output Eaton superchargers). They flow more air and can be spun to a higher rpm along with being more efficient (lower outlet temperature and less power consumption for the same airflow/pressure).
We built a 403 CID engine and ran a TVS1900 that made around 730 hp on pump gas with the stock truck exhaust manifolds. It has similar compression to the 403 LS2 described above (again so we could run pump gas at these boost levels). Here is a graph of that engine:

To get 600 rwhp you would want to run lower compression than a stock LS2 and then run more boost. Forged pistons would be recommended. Ported heads would help some as well. We have had very good durability of the production crankshafts at this power level but we would recommend forged pistons and probably new rods as well. You would also need larger injectors and a different fuel pump system than we use in our normal C6 supercharger packages.
We do offer turbocharger packages that make over 600 rwhp.
