the main problem is your gonna need to build the motor, or... drive around not knowing when and were its gonna take a dump lol my motor lasted 22,000+ mi before it finally blew (i am turbo not twincharged) but it finally cracked a sleeve (just did pistons first time around)

think about it this way, you will be asking for 100+hp out of each cylinder. i cant think of any motor with a .5L displacement (in other words 500cc) making 100hp so its not like this is done daily. we are asking alot out of these 2.0's

You choose larger than normal turbos because you don't need to worry about spool/lag time with a twincharge setup, so you're looking solely at airflow/efficiency. You don't want the SC compounding the boost once it has switched to the turbos because the SC will NOT flow what the turbos do, and will only add heat and parasitic losses. It IS however, far easier to set up and tune for a compounded setup than a sequential setup.

BTW, charged air is still moving thru the blower w/ the bypass open. There are a few kits that compound boost like the aforementioned kit for the terminator cobras.

And the compound formula was in response to the compound boost statement of 10 + 12 = 22

to me going speed density and running a compound boost setup sounds so much easer to tune. were the sc is set for a max psi and the turbo is set for a max like sc=12psi turbo=10 psi so you get a total pressure of 22psi

Going from statement one of yours of not ever compounding twincharge setups, to the end of your 2nd statement of it being easier to tune a compound setup. See the bold items in my post above
