Maybe hit ATCO I'm not putting a cage in though so faster then 11.5 and they throw you out. I have a Z06 with 600rwhp and at only 3100lbs that car can be a handful. I just wanted a good safe way to make the power and figure with the added 1000lbs of the GT500 650 rwhp would be nice.
Call buyfordracing. They have the best price, even beat Tousley. That's where I got mine.
I got mine for $4100. That's the entire kit with procal tuner.
In the next week I'll begin shipping the new VMP TVS for the GT500. It will come with a high flow inlet elbow and 2.5" pulley. If you bolt it onto a totally stock car with just a CAI and tune, it will make 620-630RWHP. If you have a throttle body, it will make around 650rwhp, with better exhaust you can end up near 700 at the wheels, with torque almost as high as the HP. I'm sure some guys will make over 700 with race gas tunes.
If you want more, swap on a lower pulley and upgrade the fuel system with pumps and/or injectors.
The blower will be priced at $3499 with 2.5in pulley and high flow elbow.
Some benefits of the TVS include OEM Eaton reliability, stock like fitment (blower swap can be done in 1-2hrs), and lots of low end TQ.
I will also offer complete packages with tunes for 10-11, and tune + CAI for 07-09, along with some TB and fuel system upgrades. The current overdrive dampers out for the GT500 are expensive because of the technology they use. I am looking into making an OE style overdrive damper to get the cost down.
My own GT500 made 748rwhp (winter) with a TVS and stock cams, and 773rwhp with cams (summer temps). When I run it with the new VMP TVS in these cool temps we are having now in FL, I expect it to make 800 to the wheels.
The TVS is capable of making enough power to push the stock block near its limit, unless you plan to upgrade the motor I don't see a reason to need a larger blower.

A throttle body is the obvious choice. A TB will add between 20-30hp depending on which one you get and if you're doing any more mods like a pulley. The rule of thumb is the more air you flow, the more benefit you will get out of a TB. You have to weigh that against the price, which is $500 or more. It's pretty hard to tell 25hp on a 600hp car, so it may or may not be worth it to you. The polished TB's do look good though.
I have the same TVS set-up and I'm very happy with the stock TB and stock pulley. Zero issues and runs like a bear. What year do you have?
