Hey guys. I'm in the process of building my turbo Z6 and I'm nearing the end of my parts list. I would like to stick with Tial because I do have their Mvs wastegate but I'm seeing quite a few Honda guys are having issues with the incorrect size spring in the Q50. Typically we run 20 or so in/hg and according to their chart we should run a 10 psi spring. But it appears most Hondas have issues with their stiffer springs. Curious to know what your experiences are with the Tial Q bov. Also tempted to look into the QRJ but not sure if I want to go with a recirculating bov or not. Aiming for low 400 hp btw. Thanks in advance.

I know there's a chart but a lot of people still tend to have compressor surge when running off of their chart.

*TiAL BOV's need a 1/4" inner diameter DIRECT source to the manifold. Smaller
lines and T's can cause delays in response time.

*SPRING PRESSURES HAVE NOTHING TO DO WITH BOOST; ONLY VACUUM.

Taken from the source.
