CAR is an 2005 Infiniti G35 AT TT w/ 2 gt2552ish turbos. -Last dyno'd ~ 500+ crank hp. (410 whp AT)
I'm a little challenged to get helpful DIY tech from the 350/G35/Turbo sites so thot I'd try here...
I am modifying the FMIC to try to smooth out the bends and generally get better performance.
Current set up Twin turbo- turbo in 2 ¼" turbo out- 2", IC in 2", IC out was 2.5" now 3", TB ~ 3" in.
The IC unit ( work in progress) is two units [19" x 6" x 3" deep] @ a 20 degree angle being fed @ the L/R ends w/ 2" inlets. -Rear exit makes an 90 up and back to TB.
The two IC units are welded together in the center and I added a L/R curved deflector to attempt to transition the air thru the sharp turn out the exit.
Without the deflector the L/R incoming air will be slamming head on each other.
It the deflector going to help?
Where there are turns of ~ 90 degrees or more would increasing the dia. help....? IC inlet is now 2". -I'm thinking of going to a 2.5" 90 with smooth transitions ….back to 2".
Is going from 2.5 to 3 at the IC exit help...its a sharp bend?... + 2 x 2" inlets and 2.5 out seems a little small.
