Dino Accelerates Better Uphill Than Downhill

I was playing with a vaporlock issue over the summer, which seemed to completely vanish now that the weather has cooled below the 90's.

Now I just took her for a spin, and in addition to the smile it puts on your face to hear that thing come to life and warm up, I noticed a pretty fantastic performance effect: Going up a pretty long steep hill, it seemed to scream up the hill like it was a much bigger motor! 2nd gear was very strong, and going up into third, it still pulled awesome. Needless to say, when you take your car out for a drive, and it's running great, it makes for a very satisfying outing I'm wondering if good 'ole tuning of the engine and headers is to be credited. Uphill, EGT is appreciably hotter, and so is rarefaction creating better mass-flow. I gotta experiment with that again. I didn't have it instrumented, and the performance is strictly a seat-of-the-pants feel, but it made me love the little car. Anybody out there ever notice this phenomenon??

(Of course, the radio went berzerk as I was heading back - Ok, now that's the car I know and love )

 

I mean the tuning done by Ferrari. Stock Ferrari designed exhaust as far as primary tubing length / diameter, and collector design.
