The last shots look familiar, the interior is a pain on the FC, but it has to be fixed sometime...

I see you used the opportunity to run power to your subs - good idea, do it right and it probably won't short out and leave you stranded.

Looks good so far.

By the way Max777, the engine is typically the driving factor in air flow rate at a given boost level. With the intake air pressure (boost) kept constant, I can only think of two methods that the air flow rate through the engine could increase by merely changing the turbo:

Method 1: More dense air (cooler charge) due to a more efficient compressor. This actually helps the engine keep from detonating.

Method 2: Lower exhaust backpressure due to a more efficient turbine - decreases the exhaust reversion which lowers the intake air temperature... once again decreasing the tendency to detonate.

The project looks good!
