Unless your dumb like me and invest in Bunting:bangTwins are cool as hell.
Twins are cool as hell. WHat do you guys think about this setup?
S400 74mm with a 1.10 a/r and an S300 66mm with a .88 a/r
Myself...I would like to try a 62/70 for the top, and a 78-80mm for the bottom.
Reason: the II 62/70 is waste gated internally = less piping mods...
FYI: This setup sounds very familiar. A 62/70 is best suited with a 71mm or 74mm bottom charger. I'm running a 62/70 and S480 and the backpressure is a wee bit high when the boost rises over 35psi. That S480 flows ALOT and the internal wastegate is nowhere near big enough. A box stock S400 with the 74mm or 71mm wheel would be a better setup if you do not want to plumb in an external wastegate also. I will be putting one in for next year.

Hey Tyler,
What A/R is your Turbine housing on the S480? What size are you planning on running with a 74mm?
Second question,
Why not just run a larger hp charger and an external wastegate. Like a 64mm or a 66mm?
Extended power is that your experiance or your opinion cause tyler hit the nail on the head. Tim the 1.10ar is a bit small if your lookin for 1000 hp.
