Well, after doing some more research on the limits of the stock block, It seems that the rod issues are luck of the draw and mainly the earlier year motors that have the problem.
If the rods hold up then the limit of the motor is higher then I first expected. It is still unknown how much power...
Partly it is the driving styles and the context. Got to remember this is all going in a 5000lb SUV, it is not built for taking corners. The thought of that is scary lol. It is a pure straight line truck.
Then you have a few other factors like I am in Texas, the land of the arrow straight...
In a track car a twin-charge setup would be killer for sure. No argument there. Twin-charging has it's place no doubt. I still want to try a setup myself someday.
A street driven car is not a place that a twin-charge setup would shine IMO. It is rare that spool actually matters on the street...
This is true but for that to work I would need a much larger turbo and a larger supercharger, costs get way to pricy for that to be practical for my goals.
I just have this big problem with a anything working harder then it needs to, I really like efficiency.
If I had an all out track car that...
Thats what I have found out. I was hoping that you could get the low end boost with only minor losses after that but it looks like a pipe dream. No free lunch as they say.

I carry a gun cause a cop is too heavy.
If guns kill people, then Spoons make people fat.
The problem with doing that besides the IAT's being way higher is that the turbo would simply be way out of it's league in this setup. It would be making maybe 5psi of boost, this turbo doesn't really come alive till the mid ~20psi+.
I don't think I will make anywhere close to as much power at...
Sadly changing the supercharger is not an option due to cost. It would have to be a 100% custom setup for the supercharger which would run many times the cost of the turbo kit and still net me less power.
I think I have pretty much decided to just do away with the twin-charging plan. I will try...
Once again good points, I think we are starting to understand eachother.
I looked into pulleys pretty hard a year or so ago when I decided to really fight the belt slip I was getting and with the way it is setup on these trucks you have to get a fully custom CNC machined crank pulley along with...
All good points, I will address them in order.
Wider/Toothed pulleys are not an option due to cost. To have a full custom set made would run at LEAST $1000 and it is simply not worth the cost. Spinning it any harder then it already is, is pointless. It is already a heat pump.
Same for using...
Oh, yeah missed you had a 1.6l, Then your math is right there.
And yes you should have no problem spooling the turbo, the real problem will be making use of the turbo on pump gas. It will hardly be making any boost when you are well into the 20psi range.

Well, technically is it called PSIA, got the A in the wrong place lol.
It is basically using the BAR scale except adding 1 to whatever the BAR number is. You are adding in the ~14.7psi of atmospheric pressure that is on everything basically.
In the case of 16psi.
16 psi = 2.1 PSIA
2.0 x 2.1...
How much boost is the supercharger making right now?
You can do some crude calculations based on the boost in Apsi to get an idea of what the turbo will spool like with the supercharger.
The supercharger will make the engine look bigger to the turbo. If you are making say 8psi on a 2L motor...
I had considered that for awhile but after some looking could not find anything close to the right size I would need. That would be the perfect solution though. If you know of a sub 2.7 inch pulley with a clutch I would love to know where it is.
Smallest I could find was around 3.5" which would...
That was my thinking on the matter and exactly why I said what I did above. I just don't think the belt could even drive the supercharger in full compound mode without a massive underdrive and even then it would be close. At that point I am also at the point of why leave the supercharger on at...
Mike, true but I would have to underdrive the supercharger down to ~3psi to have it not be past the limits of the belt traction. From what I have read on this site it seems that compound boost is harder for the supercharged to compress then normal boost.
As it is, ~10psi is the limit for belt...
