twin charger
i want to do a twin charger setp on my car. i want to make alot of boost and dont want any lag. so i have the supercharger for instant boost then a huge turbo top end boost so i get a 6psi s/c then take that 6psi and compress it in a turbo to compress it another 6psi will i have 12psi final or 36psi final. what do you all think

Easy. Been there, done that.
Turbo feeds Supercharger....

but to anwser your question of boost, it depends on each compressors efficency, and just with some guessamation math, running a turbo (first stage) at 6psi would give you a 1.4:1 ratio, and the 2nd stage which would then would prob be compressing at the same ratio (assuming it's set for 6psi on it's own) of 1.4:1 then you would have 2.8:1 of boost.
assuming your at 14.7 static, you would then be at 41.16 static PSI. resulting in ~26.4 PSI of boost.
that's about as simple as it goes...

well heres the problem...outside of it being horrendously expensive....the boost supplied from the turbo will just run into the back of the blades of the supercharger thus lowering the boost output from the turbo (not to mention possibly damaging the supercharger fins).....i had this idea a while back....looked into it pretty extensively.....not a good choice haha

its not like im saying that your going to see less boost with both than you would with one because you will see more
im sorry if i made that a bit hard to follow
but what im saying is that you would be more efficient/better off to run two turbos of different sizes with a crossover to equalize the back pressure than you would to run this system. try it if you want and nothing is holding you back but i have looked into it... i work with engineers...im going to school for engineering and they agree that this is less efficient
let the flame begin
