Hey guys, I wanted to ask you a question. My buddy and I are planning on doing a single rear turbo on his stock lq9 with a 4l60 that has a 3200 stall. He found a Master Power Turbo T70 with an .63 A/R online do you think this will be sufficiant enough for his 550-600whp goals? I think the A/R might be a little to small any input would be appreciated. Btw this is just his daily driver he doesn't plan on tracking it just wants a little more power with as little lag as possible.
