I wonder if it would be practical to go with an even smaller first stage turbo like a 13b, or even T25, to start spooling that much sooner, say mid-to-low 2k rpm range. Also, what about swapping a 6cm housing onto the 16g for quicker spool? I'd see the trade-offs as potentially loosing some peak horsepower but stretching the torque band that much further down the rpm range. Would it be worth it? Just some things to explore. Again, great work and thanks for sharing.  |
An interesting thought, about doing anything you can to get more torque around 2k, but what I took from RayPeter's experiments is that our cars really don't enjoy boosting at such a low rpm - but who knows, maybe that's simply a tuning issue that can be ironed out.
