Sweet spot 4 GTQ70

[Not Avg 6]

What do you guys think the most efficent boost range is for a GTQ70 w/ .85 housing? Max boost before any power lost?

Thanks

In my opinion it will make the most power at 26 psi. It will make more power above that,but you see less returns per lb of bost.

This turbo is similar to the GT67. It makes goobs of power at lower PSI. My car went 10.20s at 20-21 psi.

Thanks, Louie. I feel real comfortable at that 26-27 lb. limit. I kind of figured that since it was designed as a TSM class turbo higher boost would'nt result into much more gain. Have'nt been to the track yet, but it's a monster at that level.
