Anyone running 4-6LBS of boost? Stock bottom end
Just curious to anyone running low boost how is it holding up? What power levels did you hit. Anyone have a TVS2300? I see that supercharger are cheap used only 1-2k more than a mamo ported msd and NW102

Those boost levels are fine provided you have a competent tuner. A TVS2300 wont fit under your hood, so factor that in as well. In addition, you will most certainly want to swap out that BTR4 cam to something more boost friendly.

I would stay N/A with an LS7 stock bottom end.

well food for thought but on an iron truck block (4.8-6.0) you can do 1000hp flywheel bone stock bottom end omit gapping the rings (and using Gen IV rods). Those figures are up in the boost (19-24lb usually) and usually E85, but, for all intent and purposes of demonstrating how good a stock GM truck bottom end is, you get the picture. The LS7 being aluminum is not going to be like an iron block, but I think you'd be safe in the 10-12lb range, provided that you're not stupid with the timing, stay on the rich side and be sure to run cool IAT after the blower/turbo. So in essence, yes 5-6lb on the LS7, following what I just said, you'll be good all day long.
BUT, Mamo's set up (heads and intake) really works well, if I were you, if I had an LS7 I would stay NA.

Roots tend to heat up the intake air more, because of their location and how they work. Then you have the Procharger type blower which I think are the best of both world, but tend to be expensive.
For cheap, big power, I will still claim a turbo set up to be the go to package.

depends on the application and the use. For all out power, which is seems is what you want, Turbo all the way, the most efficient at delivering power, but a bit more complicated to set up because you have a hot and cold side to deal with.

I just thought instead of spending 2k on a NW 102 and mamo intake spend 5k on a used root style supercharger on minimal boost to achieve 700whp maybe ? With headers heads and cam and meth. But I most likely stay NA then and down the road go boosted when I build the bottom end. I heard it's the piston ringlands the only reason boosted is bad

Ya, that's exactly what I run on my procharger

I believe that they both are running 5.5psi boost and with their canned tunes are very safe. You don't need to have a tuner touch them. In fact, I believe their warranty is voided if you don't use the canned tune that they come with. The E-Force is rated at 657 HP, so not really a need to change the canned tune for more horsepower.
If your engine is not stock(before you add the blower), then a tune will be needed, but, as with any blower installation, the quality of the guy tuning the car is of upmost importance.
The bottom end of a LS7(rods and crank) is great for a supercharger. It's the cast pistons that can give problems with too high a boost, especially with a crappy tune.
The cast pistons work very well with the E-Force and the Heartbeat when used with the manufacturer's pulleys. Start upping the boost and you can get into trouble.

Both the Edelbrock E-Force and the Magnusson Heartbeat are TVS2300 blowers and they both fit under the stock hood.
