I think I am just caught up in tinkering. We are fortunate that we have him....he saved me a lot of money testing things I was going to try. I tried to make an honest test of the two manifolds. With the wrap-around manifold, I was unable to go past 1/2 throttle without the engine bogging down and losing power the more I advanced the throttle. Max RPM's I ever got were around 4200 to 4400 during a surge. Today I finished installing the short, straight Atkins manifold. Same throttlebody and injectors, just longer fuel lines and had to make the throttle position sensor wires longer. I made NO changes to the ECU settings. I fired it up today, and saw an immediate improvement. I thought it ran very well before, but I had nothing to compare it to. Idle was smooth and clean, and throttle response was much faster. Once I reached the 1/2 throttle position, further advancement of the throttle yielded higher RPM's. Hooray !!! Got it up to 4800 rpm's, and on another try it hit 5000 rpm's static. My prop is a huge 3-bladed performance 64 x 78 wood prop. (possibly over-propped)? All I know for certain is that I have considerably more power, better transition from idle to midrange, and I now have power above midrange. I was able to go to WOT smoothly. Now for the BIG plus....No more after-shutdown fuel drip. NADA...Nothing....ZIP !!! Today I left the hangar smiling.
