Is It Better To Spray A Wet Shot In Front Or Behind The Throttle
Body?

 

I would say before so you get a good dispersion of the shot... I would think if you sprayed after you would be missing the first two intake runers.

 

i really dont understand the concept of missing the first 2 cylinders. the pictures of the inside of the truck intake looks like theres no runners there just a hole in the back of the intake and the air makes kinda like a u-turn and hits number 7 and 8 cylinders first.

 

could be.. I honestly cant remember that well... been a while since I looked down one. and it was pretty dark then... I would still say spray before the TB though.

 

i think you could spray either way. i know i sprayed mine right before the tb. ive seen people use the egr slot on the intake to spray. when i was doing the cam swap in my truck i looked into the tb at the intake and all i could see what that one hole in the back of it. i tried searching but didnt find anything

 

The truck intake is completely different than the F-body and vette intakes. I have not looked closely but you should be fine either way.

I have the radix on my truck. I was wondering if there was any difference in vacuum before or after at WOT?

 

ahh didnt see you had the radix. i think you would be better off with a direct port setup if you plan on running anything bigger than a 50 shot.

 

as far as the truck intake goes, you will be fine spraying after there TB. i had my old setup that way, as well as slowprocess'. i have one of Daves nitrous plates now which pics are coming. but with the way the truck intakes are designed there is no way possible to over spray the first two cylinders.




you will see why you can't overspray number one and two. thanks bigtex for the pics that i am using here. this is his work to show us all the difference between ls1 and lstuck intakes.

 

thanks Goshawk.... I have never seen a cut-away like that... with the radix though I would think a DP system would be the best
