qwik LO3 nitrous question

about a year ago i had the TBI nitrous kit on my car well to make a long story short it made 2 12.8 second passes and blew a head gasket

so i sold the kit and popped on a new gasket and what not

today i have accuired for FREE a universal dry kit. My question is can i just get away with screwing the nozzle into the base of my open element air cleaner or would i have to invent some kind of different intake for the car??

all input is much appreciated

NOS makes a product called the "top shot" It is a whole air cleaner base with the nozzle built in it. It hides your nitrous system so nobody can see it. But a dry kit WONT tell your computer to boost fuel. You just have to chance it. You cant go as high of a shot with a dry kit.

I'm pretty sure that won't work on our cars.

1.) The fuel injectors are in the way.

2.) The little ring that goes over the air cleaner stud has 4 spray nozzles (pin holes). We only have 2 bores.

Other than that, it was a good suggestion.

hmmmm I thought there was one for the TBI. Anyways i do know that there is a plate for TBI. But i wouldnt run a dry system on anything. You should convert it to a wet system. Im thinking of getting a wet kit like i had in my truck You could run a tubular CAI and put t6he nozzle in the "hat" that sits on top of the TB. Thats what i did to my S-10 like this. http://members.cardomain.com/nitrouspowrdss

What are you going to do to supply the additional fuel?

lol let the 02 sensor tell the cpu to try to maintain that 14.7:1 air/fuel ratio

doesn't work at WOT and 14.1:1 would be pretty lean on nitrous

our cars go entirely off the fuel tables at WOT, this is why making your own chip is SO important. (sorry, I am going preach here for a minute.) The O2 sensor comensating is the most misunderstood thing about our computer system i think. the only time it really does anything, is idle, and part throttle cruise. those are not times that we need/want more power.

also, our cars tend to make the most HP, at somewhere in the 12.5-13:1 AFR, not 14.7:1 our narrow band O2 sensors, are only acrurate right around 14.7:1, by the time we get to 12.5:1 they are very inacurate. even if the computer did correct at WOT (yes I understand the stored BLM and WOT bit, lets not go into that in this thread.) I would not trust our hardware to maintain the desired AFR. My guess is GM knew this too, and that is why there is no O2 correction at WOT.

i just thought of a very cheezy way to do it.. however i dont know if it would work, or if you would blow your engine with it.

what if you closed the return line.. i mean when the nitrous is on, have a 'noid CLOSE and the fuel return is effectively off.. that would raise the fuel pressure alot, and thereby give more fuel.



but i would ONLY attempt this if you intend to blow up the motor. this isnt for your daily driver, or even your fun toy... just somthing to do to a junker before you pull the motor and toss another one in.

you need to do it this way:

easiest way is to just post the text and have it do it automaticly...

the other way is to do it like this: (with [] where the {} are)


{URL=http://www.TheWebsite.com} this is the text you want to show up {/URL}

and it would come out like:

cant a wet system be sprayed into the plenum of a single plane manifold tapped for appropriate fogger nozzle? or better yet 2 nozzles?

Our stock pumps are so weak chances are the return line would be dry if you had it capped or not and the motor would be using every last drop from the feed line.

Ronny, just use a wet fogger system. you can get fogger nozzles that spray both fuel and nitrous, as long as you know your FP, you should be able to get the right jets for it.
