Enginegasm 

noun.
A highly tuned car's engine has an enginegasm when it is revved. It's that beautiful sound you hear coming out of Porsches, Ferraris, Lamborghinis, etc, that causes you to eargasm.

Jake told Kat about his Porsche 911 Turbo's enginegasm yesterday. He subsequently had an eargasm. It sounded so good!

something geeks, nerds and others with a logical, scientific or otherwise academic nature can have when experiencing things related to a favoured field that they find particularly mentally beautiful and/or satisfying.

- Did you see that documentary on jet engines last night?
- Yeah! When that slo-mo footage of the full power blade off test was on I had a little engineerasm.

When we got round that functionality problem by using a cross-scope lambda expression as a parameter of that delegate code I totally had a massive engineerasm all over the compiler.
