Nozzle placement for meth injection

[dsmmike50t]

I'm having a little trouble deciding where to place the nozzle. Below is a pic, can someone tell me where the best spot would be.

A: Nozzle pointing into TB

B: At the angle

C: On top, with elbow.

I'd say the best place is where you drew an A, right on the elbow. I've seen several cars doing meth/water injection and that is where they do it.
