Quick NOS question!!!! Advice needed!!

**whazuupgto** · 03-02-2008, 05:59 PM

I currently have a 100 dry shot on my car.. I have it spraying behind the mass air flow. A friend of mine that works at my local dealership hooked it up.. works fine.. Today another one of my friends looks at my car and we talk about the nitrous system.. he has had many years of playing with nitrous and can't believe the way its hooked up... he begs me not to spray anymore until he can help me change it. He says I will surely mess the motor up if its not changed to spray in front of the mas.. along with some extra fuel that we need.. I don't know who I should trust and who knows what there talking about .... please any and all advice appreciated... sorry so long!!!

Your friend is right. Only a wet shot can be sprayed behind the MAF. A dry shot should be before the MAF and you should get a wideband reading on the 100 shot at WOT just to be safe. Yeah, you might burn your motor up spraying it like that.

the dry shot has to go before the MAF, so the PCM can add fuel.

you have been lucky, don't push your luck

I had to upgrade my fuel system on a 125 shot, but then again I have a 2000 w/ smaller injectors. Also,it's a wet shot w/ a TB plate, but Im not sure if that makes much of a difference since more fuel is needed w/ a dry shot. But DEF. move the nozzle in front of the MAF.

dry shot goes through the maf always and a wet goes behind it directly into the throttlebody
i would be hella pissed at the guy that hooked it up,he definitely would not be anywhere near my car again

Yes it is in the wrong location!! I will guarantee that your spark plugs are ALL peppered up with aluminum from your piston and passable pitting on the head around the plug.

I would HIGHLY recommend you change the plugs to an AutoLite AR94 race plug with the gap @.38 and change the oil.

You can detonate these things quit a bit before catastrophic failure.

Try to make sure your spraying straight and not off to the one side which I have sen many do also.

Here is a nice pic that I was sent that will give you all a visual of why I prefer these and NOT the NGK's everyone tells you to run.............

AutoLite AR94 on left NGK T??? on right.
NO COMPARISON!!!!!!!!

Thanks.. I got started today rounding up some necessary parts to get everything right... until I get everything fixed no spray for me. I will definitely be sure to change plugs...

Has that Autolite AR94 been modified or is that stock?

Thats stock. Alot of real race plugs are designed like that on the ground strap to help eliminate fouling.

It is a way superior design than the NGK's everybody recommends! Well if you can't see that just by looking at them you have to be blind.

We run them in ALL our nitrous and N/A race motors for the last 10 years.

There are nitrous products on the market that allow you to run the nozzle after the MAF. if you dont want to relocate the nozzle and have to plug the hole you already drilled then i would look into that.
