nitrous as 7th injector.

i have the edelbrock wet n02 setup on my car. i've been playing around with it recently, turning off the bottls and spraying just fuel, just like a 7th injector.

i don't know why but it doesn't do a thing. if i use a small (.024, 025 and 026) nossel it doesnt' do a thing at all, doesn't reduce knock what so ever. if i go a little bigger, .028 and .030 the motor just bogs down, knock does go away but so does all power.

I remember hearing abut the 7th injector that would help reduce knock. my thoughts are maybe if i were knocking because the injectors wouldn't keep up and it was going lean, then it would help but with the sane boost levels i'm running now i'm just pointlessly dumping fuel. does anyone have any ideas of making this an effective knock reducing thing? i'm getting around 3-4 deg. of knock that i'd rather not see on the street. i'm not trying to get 20#psi out of it, and not using it as a replacement for race fuel. i'd just like to controll the little bits of knock i get on the street.

Your shooting the wrong kind of fuel. You can get the same results by increasing fuel pressure... but then your O2's go up and the power comes down.

Your fighting the very issue that is why we use alcohol injection.

No amount of low ocatne fuel is going to create the power you want.

The 7th injector was for cars running stock injectors maxed out and wanting a little headroom. But not knock control.

ok, makes perfect sence. this is down the road, after i rebuild the motor but i'm going to do alky, race fuel is costing too much. but anyways what if alky was injected along with the nitrous? i know i know, forget about the no2 and turn up the boost but i already spent the money for it so i mine as well use it.

so i'm sure its possible but would be be beneficial to use alky in place of gas? or would i be best off just running both nitrous and alky?

i'm asking now because i'll probably forget later. i know the way i think.
