Yeah spool is crap. I am looking for a single scroll hotside. So I can be full single scroll. Will I get better performance that way.

 

Yes.

 

Interesting, is it a T3 .78 TS housing, how bad is the spool compared to a single scroll t3 .63 GT30R?


Is the top end power higher or lower compared to a single scroll t3 .63 GT30R?

Actually my wastegate valve broke off the piston that is why spool sucked. Jake at tial sport rebuilt it with their new one piece piston/valve and freshed everything else for free. What a great customer service experience. Anyway I am at full spool by 3400rpm. I love it now. The bad wastegate just sounded like a small wastegate for a few weeks then a bad rattle. Like i said spool is great now.
