How do Twin Turbos work?

[cdx2k1]

It's a parallel setup but I don't know how it's done>1 exhaust/turbo manifold for 3 banks or 1 exhaust/turbo manifold for all 6

It's 1 turbo per 3 cylinders.... not complicated if u think about it.... keeps spool times quick while giving the flow of a larger single unit...

I was actually looking for some info on this awhile ago. Thanks fellas.

ok this is a really dumb example of the skyline's rb twin turbo setup...
umm its basically 2 starlet engines lollllllll
two... 1.3L turbo setups...
so yes.. its 3 cylinders (1.3L) to spool one turbo ( T28 )
and yea on stock boost they run up to 7-8 PSI each,
so just about 16psi STOCK...
however... with a boost controller....
these turbos can boost up to 14-16 psi each,
therefore fully insulting the stock HP rating of 280HP to somewhere close to 320-340HP

congo,

Aye fellas, is it possible to put a twin turbo sequential setup on a starlet? (just curious!)

yes it is possible but the next question would be... would it be efficient?

yes one turbo would spool the other and then further result in more responsive boost right?

HOWEVER..... what is spooling these turbos? the motor which displaces how much?
1.3L? this would not be as efficient as suggested, because this engine would not produce as much exhaust to fully maximise the use of the two turbo chargers...

and yes it would have space... but the next question is where are you going to get a twin turbo manifold to fit a 4E-FTE? and even if so...
what turbos are you going to use?
two CT9 turbos?
this boosts max up to how much PSI? i think ive heard somewhere around 11psi...
so even if you DO attempt this... two CT9 turbos @ 11PSI each isnt that bad.. but it'll take FOREVER to reach this boost level!... well somewhere far down the quarter though...

if you would like a simple alternative option...
just slap on a CT26 , this turbo comes from the 3S-GTE (2.0Lturbo)
this turbo spools up to max boost of (22.2 psi is the most ever recorded i think )
but reaches 15psi easily...

most of what i said prob made no sense.. but... sorry

When you run a parallel setup and two turbos are boosting, say, 6 psi each... you don't actually get 12psi (6 + 6)... But rather you get 6psi, but double the cfm airflow of a single unit.

(When boost pressure of 2 turbos are combined into one plenum, total cfm doubles, but not total pressure.
