It was taking quite a bit of right rudder to keep the nose pointed straight ahead - but with the nose wheel all was managable - until I lifted off. 
 
Is this still with left offset in your mount, or did you take that out? 
 
The good news was ROC was over 1500 fpm which for my lead sled was about 400-500 fpm greater than normally with a full load of fuel. 
 
What rpm were you seeing in climb, compared with this same intake before?  I'm wondering if this increase in climb is a result of making more power, or just better prop efficiency.     
 
Also, this was the first flight with my 2 GM cores inlet area reduced to  a total of 28 sq inches, temperatures were what I would excect on climb-out on a 65F OAT day.  Oil was approaching 200F and coolant 210F when leveled off at 3000MSL and soon dropped down to 165 Oil and 170 coolant at 5200 rpm at 6 GPH fuel burn. 
 
This is interesting.  You can't really compare the water temp, since the inlets were changed, but are you saying the oil temp is the same as what you would have had with the old redrive and prop?  Mine went from great, to out of control with the changeover. 
 
So hopefully the computer is finished with its problems and I will report more from next flight.  So all in all I am very pleased with the first flight.  My intially impression is I may need to have the prop trimmed an inch or so as I would like a bit more rpm for take off and climbout.  But, will conduct a bunch more flights before deciding 
 
I agree that it all sounds very promising.  Congrats!
