What setting should I advance/retard my cam gear to? 16T turbo
 
I am asking for some experienced advice since I do not know much about advanced/retard cam gear settings.

Right now I am running,

- fresh 1994 b230ft squirter block
- ported 90+ manifold
- 16t
- 3in DP
- 2.5in exhaust
- Yoshifab catch can
- new green top injectors
- Sbabbs chipped lh2.2 ecu
- AW71 accumulator mod
- AEM AFR

The next step is the turbo cam and cam gear that I have but my question is, with the higher HP mods I've completed so far, what should I adjust my cam gear to for higher mid to top range power? I know there is different advance/retard settings but I'm unsure what I should adjust it to. I appreciate any advice. Thank you

Not to be a smart guy, but a properly selected cam needs neither advance nor retard.

Depends what you want out of the cam gear, advanced moves peak torque to a lower rpm, retarding raises it. I have an A cam all the way advanced in my NA 245 because the automatic is happier at lower RPMs. I initially bought the gear for my 242 +T so I could retard it and get a little more top end for autocross.

With that said, a lot of European cars can advance/retard the intake cam dynamically

Yes, but in this case we're talking about a camshaft with fixed timing.

My experiences is that Volvos redblocks are not very good to responding cam timing changes.
I had a r-sport turbo ic 244 in early 2000's and i put a cam gear to it, i tried to advance it but i didn't notice anything in butt dyno. I try first 6degrees then 9 and nothing happened.

Unfortunately this car only had about 200hp, so if it was more powerful then maybe cam advancing changes power curve more, but i don't know.

Also i only had a D cam, so if camshaft was more let's say racier then maybe it effects something, i'm not sure.

Also unless im mistaken advancing will make your turbo a lot hotter, at least i think
