Twin charged, Innovate on top and AVO on bottom

So what happens when a high pressure, cooled mass of air hits another compressor?

Fueling would be the limiting factor here.
Engine internal is another but could be negated via higher octane fuel source.
You are also not looking at outright HP in shoot out mode for a twincharge setup on a stock engine.
The largest benefit would be area under the curve, build for higher torque through out the entire rev range.

It compresses it further. That doesn't change the difference between air mass and air volume. Do you know the difference? If a given object chokes at a given air mass, further compressing the air isn't going to help that.

I'm no expect on fluid dynamics, though, but i'm sure someone can chime in to talk about the friction aspect of it.

It's sponsored by a lot of aussie companies, sprintex/avo etc no idea how much its costs.

if you're going to do something like that, you'd want to use a lot bigger turbo than that which comes with the avo kit.

We have good quality pump here. 98 RON and e85 (~82%). Personally I think with a small turbo, all the effort would have negligible effect but let's wait and see.

Well its going to cost more than an Avo + Sprintex. Basically a $10k+ engine with the performance of a diesel, its a tuner competition for P.R. Nothing wrong with Aussie gearheaded fanatical compeiton but that's all it is.

The fact that they aren't flow matching the two compressors says everything.

Yeap, united is pretty good.
Sure the turbo could be much bigger, I would do the same thing though if I was going to fatten the area even further, not otherwise possible with both kits on their own..
Then again, I couldn't careless about peak HP but instead, how the engine makes power everywhere else.

Id rather pick one kit

And use the money id spend on the other kit and fabrication and build the motor.

Indeed. The AVO turbo is much to small for a twin-charged setup.

Fair enough, you would most likely need a pretty aggressive stroker kit to match the twinscrew. I would rather not deal with messing up the bore vs stroke ratio though.

I feel like anti lag with a turbo or a bigger posi displacement supercharger(since ours is at its limit apparently) would be a better option. our high comp motors cant really eat the boost #'s that twin charging is good for, its a waste of money to develop a true twin charger system just for a couple more psi. Now if you dropped to some low compression pistons and pushed 10 out of the super and 20+ out of the turbo itd be a reasonable investment....but thats just my opinion.

I got the idea from working on the newer twin turbo diesel truck engines and the older 8v92 2 stroke 8v twin charged engines.
Here's an article I found

Look up 4agzte, hks also had a twin charge kit 20 years ago.
I also have a 4agze in the AW11 and have been looking at trying this too.
