I have two turbos sitting on my work bench - I've toyed with the idea on and off for years, but just couldn't convince myself that I needed one since I tend to cruise at lower airspeeds to keep the fuel burn and $$ down.  If I needed some extra boost just for takeoff, I'd probably just go NO2.  But, if I were to do a turbo, it would not be with the stock Mazda turbo but would use something like the TO4.

I'm also toying with this decision, but fortunately in my case I have plenty of time to make up my mind. The thing that keeps rattling around in my head is that the Cozy I'm building was really intended to fly high. I see pilots talking about exactly what altitude they start their oxygen, and it adds fuel to my turbo fire.

What I haven't been able to quantify is exactly how beneficial the turbo is in this case - normalization. It seems you can calculate the numbers to support either argument, and you have to weigh your goals against the pros and cons of either decision. Sometimes choice is a bad thing.

I guess, in the end, I will probably install a T04 mainly because I'm following closely in John Slade's footsteps, and so far his T04 is working out. I have enough time to watch how it continues to perform as he builds up more hours on it. So far it seems promising. Eyes and minds open, I guess.

Regards,
Chad
