Compound Forced Induction
OP, doubt you are going to get much information that pertains to C5's on this topic. I been around here a while now and have never seen one of these setups actually get done with results. You have run into a topic that always runs off the tracks, like every other time it has come up which has been several. Turbo diesels and Fords always come up in the conversation and then the insults start flying. Usually the OP gets all bent out of shape cause the forum public ain't down with their idea then everybody starts tossing around ****, not that that is what happened here.
Several forum members have tossed drug on top of boost with strong results but not boost on boost. I'm not saying it can't be done, sure it can with enough $$$ and moving stuff around underhood, not much space if ya haven't noticed. Plus the cars are pretty light so the giant TQ monsters have all kinds of traction issues.What I would like to see is you get so determined to prove the board wrong that ya actually get it done! That would be awesome the ya can come on back and tell all the naysayer they don't know nothing and to go suck it!

You really need to go back and read how all this started.
I'm not saying he falls into that but as I said, I have yet to see one person on this board make compound boost work in a C5. Its costly enough getting these things to perform going SC or Turbo let alone putting both into the equation. I just don't see where you will get a constructive conversation on this topic, in this section on an actual C5 or C6 for that matter.
Carry on all,

You have an opinion, great, so does everybody else and guess what, that's ok! That's all I'm trying to say here. We don't really need to go out of our way to point out every last person as an *** that gets on our nerves, just to much work over nothing for me.Hey, maybe you could try this question over on the Mustang Forum and see what they have to say, then come back and let us know.

THIS^^^^^^^
if you are interested in a few more builds get in touch with rick dobbertin
he did a tt roots bb chevy in the old blue nova
and a TT twin magnuson j2000
both were show cars and I never saw any dyno runs but they were interesting
more than a few companies use a blower that then cuts over to a fully spooled turbo to take over from there
if you want to do this, with some nicely flowing diverters and a mad max clutch on the blower have fun
I'll stick to my TTiX system. they spool plenty early and don't give up on top
to each his own. it's your wallet
But the reality of it is it's useless. The SC eats alot of energy. 100whp to be exact on our setup. Below 4000 RPM's there was more tq and more power, but nothing so huge everyone should run out and try this. I mean, we could generate 30psi at 1500 RPMs, but that's not quite as powerful as it seems. At 1500RPMs the cam is still WAY outside it's efficiency range, so the gains were.....ehee.. The downside is that the IAT's where all MUCH higher, and anything after 4000RPMs lost power do to driving the SC; and we compared it at multiple boost levels.
Now I'm not sure about you, but when I want power, it's because I wanna go fast!!! And when I wanna go fast, I don't spend a whole lot of time below 4000 RPMs. Hell, I'm above that when I come out of the hole!
Sure it produced a better tq curve below 4K (where it doesn't really mater anyways), but a simple light shot of NO2 worked MUCH better than the SC did! Way better gains, way lower IAT's, I could shut it off when I didn't want it, and no power draw up top. When only using it to spool it would activate at 2500RPMs and literally spray for 0.5-0.75 seconds. With no-lift-to-shift, it would only be active once. A 10lb bottle would last forever!
So sure, it "can" be done, but again why? Lots of complexity, lots of cost, cheaper/simpler/easier/better ways to do the same thing, and all you end up with when you're done is the ability to brag "well mines BOTH!". And generally when you're impressing someone with this, it's because they don't know you've just made your car worse!
