My understanding is that nothing should be vented anywhere to the underside of the car if it can be avoided. Using low pressure under the car to extract would incrementally increase the pressure under car. That the engine bay air is heated might make it worse. If anything, I think a few holes in the stock under panel need to be patched up once venting to the top side is done. It's probably less of a factor in stock form, but I want to eventually have the bottom as flat as I can reasonably make it.
