REFLECTOR: N4PE "The Ape" First Start

[Scott Derrick]

Brian,

Wow, sounds like a great success.

You give me hope.  I  wishful my conversion of a TSIO520 with a fixed 
pitched Catto,  to fit in my STD RG cowl, goes as well....

Keep us informed of the progress... Do you have temp probes on that 
induction system to measure intercooler effectiveness?
