twin 70's on a 350 tpi? correct me if i'm wrong, but wont that take forever to spool up??? i'm just curious why you decided to go with that size turbo's, not knowing the rest of your combo of course. what kind of power #'s are you looking at making? looks good anyway!

With a small a/r on the turbines it should spool up OK, but they are the big side for that application. In the picture it looks like the headers were setup for a T3, I'm assuming that your swapping that out for a T4 flange. With the Fast Burn heads it should make some power. Are you going to be driving it on the street? If so think real hard about the 8.5 compression, with it down that low it might be tuff to drive on the street. In the past we've had problems with boosted cars loading up and not driving well on the street.
the .68 i think will spool fine
by the way im trying to make it to 1000hp or as close to it as i can on pump gas so i kinda need 8.5-1 compression
