Theres a general misconception on this forum that I've noticed of a twin charged car being hard to tune for. Thats what I thought you were getting at.

i hate this...2 identical cars (even both vic red) same mods and everything...one tune works great on subject A, but same tune on subject B...runs rich as hell and sluggish as hell...

no, I'm underway right now. But there is at least one other person with an ss that I know is on base. I'll be back Saturday though.

we all know how well the canned tunes work out. =\
gimme a carb setup, and im effin golden
We've been doing the twin charged setups for years. In fact, my Grand Prix ran 9.9 with one. They need to be setup properly and they can be dangerous because if something isn't right the heat from the turbo will add to the heat of the blower and you can have some metal melting temps. We are past those days of trial and error though.
The benefit is that you get the best of both worlds. The problems with turbos is the lag. You can run a small turbo for no lag but then you don't make the big HP. When you go with a big turbo to make big HP, the car won't spool and feels like crap on the street. With a twin charged setup you can adjust the SC to cutout when the turbo spools and when you do it right, you can't even feel the transition. When you do it wrong you can feel the pieces that used to be in your engine bouncing off the pavement.
When we're done I think you guys will be impressed. We're going to price the kits similar to the TVS blower so customers can decide which way they like better.

No, as there would be no point. The blower is only there for instant response and turbo spool. The M62 is quite capable of that. the turbo is far more efficient than the TVS for top end power so there really isn't a time where it would be beneficial to twin with the TVS (unless you had a 1500HP turbo that needed 20psi of blower boost to spool)

The supercharger is easiest and the lowest cost, however power doesn't compare to the turbo. A supercharger requires over 50HP to spin it, close to 100 at high boost levels. This means a few things:
1. At the same boost level the turbo setup will make a lot more power
2. The car will put down more WHP on the same fuel system which is an issue with supercharged models already.
3. The engine will withstand the same boost as mady by a blower but put out more power before blowing up. These engines are fragile and let go around 300WHP with supercharged setups. With a turbo, they will go farther.

With all these negative things you have to say about the s/c,why are you coming out with a twincharged kit?From the price your looking to charge,i take it that it wont be intercooled?I really dont see the need for a twincharge kit.Its cool to have,but if you want max horse power,go all out turbo.You dont need the s/c to help spool the turbo if you size out the right turbo.And you even said the s/c robs the engine of 50 or more hp,so why would u wanna keep the blower on there?
Turbos can only be sized for a compromise between spool time and HP. The larger the turbo, the more efficiency and HP. The smaller the turbo, the better the spool. By twin charging we can have instant spool and large turbo HP. We will also have options for turbo only.
