anyone tried the standard 12XZ? ie the one with the blue heatsink?
how does it perform? as compared to say the normal 12TZ 5-port?

what pipe do you use for OS speed 12 xz? beside OS 1050
#81
as what i've seen here, normal xz outrun 5port tz at bottom end and less punchy on top. im not sure if its the real engine power or maybe it's because of the difference in car ratio.
XZ speed and TZ speed specII, i use hec pipe and EFRA2503 with novarossi 41625 conical manifold, slightly on the hot side but it really push mid end.
another friend uses SAGE pipe set,nice power band overall.

Here's some good info if you are attending this years on-road nats:
We all know the 1050 pipe works the best with the OS speed 12 XZ, but the pipe is illegal at ROAR events (IFMAR & EFRA legal though)...some BS about stringer length, sounds like they have a person problem to me. Anyway, I tested the Mugen MSR .12 #P01004 pipe this weekend with the OS manifold that comes with the 1050...it fits, is ROAR legal and works awesome. Maybe even better.
