Compared to many that have the bigger is better mentality, it's not that big.

Thanks for the kind words.

I've seen those projects, long ago, but there's a big difference between a custom fabricated setup, and one that's designed, engineered and made to just bolts on. Don't get me wrong, those are cool projects, just different.
Well the idea is that egbp data can help one choose a/r and turbine selection a tad better other than just the dyno plots. I'd think that a/r selection should be a tad different than a traditional up pipe version.
For example evos can get away with .63 housings in combinations that would choke a suby. It would be nice to look at another data set.
Theoretically this setup should allow a tad more top end with the smaller turbine or better spool with the larger turbine, but the dyno plot will only show the tuners tuning strategy. We can only guess the reason for a torque fall off for example. Anyways just a thought.

It would be good data since you have different housing and are switching turbos.
