Hey holset users. What to see if anyone can enlighten me on some choices. I have a hx35 t3 12cm twin scroll with t/s manifold. At 25 psi I only made 348hp 373tq....I was wonder if a 16cm t/s housing would be a better choice? Also would spool DRASTICALLY change? Every holset user I see compared to mine, im about 70-90 hp short of them. Timing, blt, and exhausts leaks have been checked, thats why im thinking its the housing. Any input would be greatly appreciated.
Timings on the conservative side for 25psi, def a few ponies to be had there. I'd leave everything the way it is and slowly bump the boost a few psi at a time watching knock and plugs.
