Doesn't really matter when you're motor and tranny limited.

 

Actually not really, yes there is a little restriction. But in the systems those companies use, they have used the wastegate as a bypass. At a given PSI it opens and diverts the flow to the larger turbo, (hypothetically) the smaller turbo only consumes the most amount of pressure it needs and the air flow takes the path of least resistance. These are the most impressive kits that I have seen thus far. They also have a diverter value on a dual scroll turbos that closes one scroll and then opens at x psi, essentially making a single turbo two (one small and one large). Of course the simple answer is running a computer controlled variable vane... but the technology for street cars is not here yet.

 

So in other words, YES, lol... More power would be made without that smaller turbo in place...

 

I would say yes, obviously... but not its not nearly as restrictive as say a supercharger after the turbo would be. I mean, I just saw a dyno where they hit around 1000 with it, but the curve is beautiful, progressive from 2000-7000 on hp and tq. But also remember that these are rice rockets and just having the large turbo for them leads to "supra syndrome".

 

LOL I don't know what you're trying to say but I run ported e7's on my 4.6 and have had amazing luck with that setup......well that and my skunk intake manifold...runnin' 9s lemme tell ya! haha

 

True, a sequential system is a lot more efficient than a supercharged/turbocharged compound system.

 

Got the meth installed yest. Still have to mount the nozzles.

 

So I just got done watching your video in the street/strip section. You said your car only makes 600rwhp?

 

Ya makes around that on a dynojet on 16psi right now.

 

And your efficiency is only going to keep getting LOWER AND LOWER, with the more boost you compound...
