I think 30 psi boost is way more than the launch force.

SignUp Now!I think there is no question from a simple g force of launch perspective the direct port would be better. There is no way of stopping the heavier laden alky users from the alky mix tending towards the rear of the intake on a hard launch. Many cars have made big power on the dyno with adding a alot of alky only to blow the front headgaskets at the track from the launch.
I can use Robert Wilson as an example 9.1 on pump gas.Boost is simply air that is pressurized in the the intake tract.
You can have a pipe filled to 30 psi and have liquid in it and still slosh it around. Dont get wrapped up in the alky is atomized completely...Im not... repeat not.... saying that every car should worry and get into a pissing contest about this.
What im saying..... is there is scenarios in higher horsepower cars that really use alot of alky and launch hard where direct port would stop the dense charge from tending to rear of plenum/plenum manifold etc.
Anyone here running a pre turbo nozzle?
Direct port is used more for fueling than cooling in most setups. There is less time for vaporization and phase shifitng. Water is a better fluid to be introduced in the intake manifold as the fluid has a stronger surface tension, and therefore less finely atomized. It doesn't have curves and walls to worry about, it simply goes into the combustion chamber. A direct port kit is as simple as a splitter, hose, and more nozzles. The main issue with direct port is the nozzles. Because the flow is cut down by the number of cylinders, the orifices are smaller and more likely to clog. Probably won't be an issue for most TB people that get a significant amount of fueling from their kits.That DPI would have to atomize like a fuel injector.
Little something I am experimenting with this year:

I often wondered if you couldnt use a small spacer with a spray bar in the center just like a NOS type setup... Would definately be a cleaner look in my opinion and would still be above the level of the alky..
Show me one of yours....Been there, done that. A few people have them I didn't sell many.
