Good points and this gets back to the engine tuning and hardware options. It’s easy to boost the heck out of whatever turbo to make more power, but that’s just going to create more heat.

I’ve had in my head for a while that I would upgrade the HPFP (sounds like xdi 35 will be enough for my purposes) and spend some time on the dyno to come up with two maps:

1. Higher boost & Emix for max power on the street. The fun map, where I don’t have to worry about heat bc the car has sufficient time to cool off bn WOT applications.

2. Lower boost & higher Emix for a tiny bit more power, but the objective to run cooler at the track.

Question: What PSI levels would you guys target for these kinds maps with the Dinan & PS2 turbos? Essentially, what are the efficiency ranges for these turbos before you’re starting to produce a ton of heat relative to the power gains?
