Geoff, I am running the FR twinscroll with a 35r and the 1.06 hotside. Goodspeed built it with a cosworth long block, tgvs and intake manifold. @ 3300 rpm I have some surging going on. Any ideas?

Also I want to get faster spool. What BW turbo would work. I'm 480 whp on 91 and 560 whp on 109. Is there a direct swap turbo that might be little bigger and have better spool?

Other then... I love the twinscroll set up.
