I dont' know about the efficiency of the LSA packaged TVS1900, but I know Magnuon had told a magazine, in a test on the first TVS'd G8 GT (it was either
SC, CHP, or PHR I think) that the TVS1900 would support up to 800 horsepower (flywheel, presumably). That's a totally different SC assembly, but the rotors are the same, but it just seems if Magnuson can get 800 out of those sized rotors, GM's set-up should be within a some-what similar range
I'd think, anyways. I need to do some research and see if there are any OEM to Magnuson SC swaps for those LSAs - that'd be a cool test
I think up'ing the boost a few pounds wouldn't really impact the longevity of the engine though - it's still got a steel crank, and what seem like good rods and pistons. It does have those piston squirters too, to control those piston crown temps', and if GM brags about it around the 'Ring, then they shouldn't have a problem with people racing these things and deny warranties (what I'm saying is it looks like it's built pretty good; not as over-built as an LS9, but still really well...)

Well, the quote from Mr. Welburn says it - not to sound like a smart@$$... Also, that 5.3 is like down 120+ horse shy of the LS3... To me - that doesn't make a whole lotta' sense unless they drop like 500 pounds...

I could be wrong, but you have to look at IAT's, CFM, supercharger speed to determine is your pushing it to it limits. And if your into modding motors putting a TVS 2300 on any motor should require forging the pistion and connection rods.

Putting a 2300 with 6 psi on a stock LS3 SS still sounds like a great option, for me anyways. I keep going back to that because I think that with that mod', a few other basic bolt-ons, and a full Pedders suspension would be perfect for me (with a little pulley action
) and probably come out cheaper than a Z28 from GM. I don't know though, because I'd still be more comfortable in a car GM set-up and just pulley-up and bolt-on a few goodies and be done.
Ugh... You gotta' pay to play
