mixers in 3.4 heads

[camaroman1181]

Aight, I've been searching around for answers about those ungodly large vanes in the intake runners in our heads. Now from what I can tell from searches i've performed, that fin basically is meant to help achieve a better air/fuel mixture due in part to inadequate fuel injector atomization. It seems most people that port their heads leave at least some of the vane in there, just shave it down and blend it better and turn it into more of an airfoil. I'm currently building a 3.4 myself and was going to start P&P my heads. I was also going to upgrade the fuel system with a bigger pump, adjustable pressure regulator and aftermarket injectors. Will I still need that vane or can I hack that out? I was thinking of a 190 lph (walboro) pump and something like 24 lb injectors. Anyone got any suggestions as far as what brand injectors offer superior atomization? I'm going with a larger cam and 1.6 rockers too if that would sway anyone's opinion. Thanks for all the info, you guys have saved my *** a few times already with this rebuild.

Well, here we go again. :rolleyes:

But in my opinion, if you are using different injectors, get rid of the vanes, period.

lol.. dont wanna start any huge debate, im just verifying what ive taken out of other research before i start cutting. Also lookin for what kind of aftermarket injectors provide the best atomization.

Very good question. Unfortunately, nobody has tested different injectors for comparison sake. Sure would be nice for someone to do.
