At what point (engine mods) are the HO's required and needed? Is it a displacement thing, compression, head work, cams?
I'm running a 10.5 comp 98" with fully worked heads, 48mm HPI throttle body, Wild Things 26G cams. I like the sound of the pipes in the video. I don't want to choke the motor but on the other hand too much exhaust is not a good thing either.
