ECS Round 2!!!!
I am so happy with the work ECS did for me on installing a tvs2300 supercharger on my 08 c6 z51 coupe that in less than a month I am back for more!!! I am heading in this coming Monday for some more goodies!! 
I am going to drop one pulley size down from a 3.2 inch to a 3.1 inch pulley and add American Racing Headers 1 and 7/8th inch with high flow cats and a tunnel plate! I am dropping one pulley size which according to Magnusson equates to a half a pound of boost to make up for the loss with the headers...
After talking to the guys at ECS, they feel coating the headers is unnecessary and they did such a great job that I will take their advice
I am hoping to get 30-40 more rwhp and rwtq with about the same 8lbs of boost I have now! I really also want the headers for a more aggressive sound! I will post before and after dynos when the work is done! Stay tuned!

Good call on the headers and smaller pulley. You'll see a very noticable difference. Round 3 = blower cam? You damn sure didn't wait long for round 2. Just beware (I know you've read the threads) that your TVS will struggle at 800rwhp

Just a suggestion - you won't notice much difference only dropping 0.1" so you should go down 0.2" at least. I've been down that road with the MP112 on my Avalanche and wish I'd just gone ahead and dropped all the way down from the beginning. I went from the stock 3.4" to a 3.25" to a 3.0". I'm currently watching for a cheap used 2.8". Each 0.1" drop on the pulley is supposedly good for 1 psi and 10 hp on the MP112.

I am not as talented as you sir! I would also be afraid of blowing up my rear end trying to launch from a dead stop with this power level! I would like to get into some occasional road racing.. Raceway park with their road courses looks like alot of fun!

If nmalik wants more blower noise, he can swap the rear pulleys for 1:1 cogged pulleys. Way more blower whine. You get to use a bigger front pulley also which reduces the chance for belt slip. Something to think about when the blower cam goes in.....

If he wants to stay under 9psi, the 3.1 would probably be just right. I was running a 2.9 with blower cam and it was in the 8 to 8.5psi range. I'm assuming he's underdriven on the rear pulleys. Not sure why Magnuson underdrives the vette TVS units and has a 1:1 rear drive on the gen V Camaros.

I am fine with the amount of blower noise I am getting from the tvs right now! I think it is perfect! I am not sure exactly what kind of setup I am running with the rear pulleys. All I know about that is that its the stock setup that the kit from magnusson comes with...
Motorhead, I don't think I will have any belt slip issues with my current 3.2 inch pulley or when I drop to the 3.1, right?

Thanks for the suggestions motorhead and BadAV! I would definitely like to stay below 9 psi... I would like a little more power but my main reason for adding the headers will be for the sound and efficiency!!

I'm not that familiar with the TVS2300 so I don't know that much about as-delivered boost levels, added boost/hp per 0.1" drop in pulley size, etc. So how much boost does the as-delivered (standard configuration) TVS2300 deliver on the Vette? And why wanting to stay under 9 psi on the boost level? There are many, many truck guys running 10 psi boost (and some are spinning it to 7K+ rpm on the shifts, which I think is NUTS!) on a stock LM7 5.3L engine with no issues whatsoever.
The MP112 delivered 6 psi boost on my truck as delivered from Magnusson. I don't have a boost gauge, but during summer weather, my setup is producing about 6-1/2 psi. I've got TOG headers and a Vinci Trucker cam (216/224-0.551/0.551-115) so these account for the lower-than-anticipated boost. I know the 2.8" pulley that I'm considering stepping down to is on the bottom end of "reasonable" without starting to produce way too much heat on the MP112.
Sorry for the questions, but I'd love someone to give me a quick education on the TVS2300 in comparison. I know it's quieter and more efficient but that's about the extent. And sorry for kinda jacking your thread, nmalik.

In addition to the differences you mentioned, one of the main differences between the 112 and the TVS2300 is size. The TVS pumps 26% more air per revolution. Also, you can spin the TVS faster before you end up making more heat than hp. You'll definitely be at that point with a 2.8" pulley on your mp112.

I believe the stock ls3 tvs2300 kit for the c6 from magnusson produces about 6 to 6.5 pounds of boost on a completely stock car (no headers or intake)... I am currently at about 7.8 lbs with a callaway cold air intake and a 3.2 inch pulley. I would like to keep the boost as low as possible for safety reasons

What exactly is involved with their stage 1 kit? Is it an in line pump or in tank pump?
Where the HELL is your new dyno graph with the new headers and pulley?

We use a fuel block to draw fuel from the tank to an external pump. We also still use the factory pump and tee both together. We use the external pump with a hobbs switch included to only turn-on in boost. The Stage 1 system uses a Bosch 044 pump and we have made 900+ with this particular pump.
Any further information please let me know. The cost on the Stage 1 system is $1295, on sale for $1195 right now.
