I am setting up my wet nitrous kit on my 99 Z28. I am trying to decided where to plumb my nozzle in at and I have the stock accordian style bellow which I don't think its solid enough to hold a nozzle and not have the nozzle twist and turn inside it. My question is can I drill a hole in the throttle body on the very edge farthest away from the blade that I can get and tap it and thread my nozzle in there? The only thing I am worried about here would be good distribution but I am not going to spray under 2700 rpm anyway so what do you guys think?

 

Like you said i dont think distribution would be any good. Best bet is going to be to get a smooth bellow, instead of that accordian.

 

why not go into the back of the mass? thats were im plumbing mine in....

 

Even the smooth bellows though are just a rubber or plastic and I don't think they will be rigid enough to hold the nozzle and not have it twist and spin.



The back of the MAF is not a bad idea though, I never thought of that. That would give enough distance that distribution would probably be better. Anybody think of any reasons why that would not work?

 

Thats were mine is located worked pretty good, has never backfired under 3k launches. plus i think you can get a maf cheaper then a TB

I agree though the back of the MAF would be great.

 

drill and tap the back side of the maf or get a nozzle adaptor fitting. either way is accepatable. I would not tap the throttle body just my opinion.

 

Believe it or not, I have done a few in the stock bellow and its not as bad as you would think. If you're still concerned about it, I would go slightly back more and hit the backside of the maf housing (end closest to throttle body). You can drill and tap that for a more solid foundation. Or, I don't know if this is an option for you but maybe a reinforced smooth bellow with nozzle retaining nuts? Thanks.

mine is in the stock accordian bellow and it is fine

 

I ran mine in a fernco bellow from home depot for over a year and a half and never had any problems. Just like Dave mention get some rentention nuts the screw together from the inside and out, holding the nozzle right in place.

 

Thanks for the good ideas guys. I didn't even know they made those nozzle nut things to help hold them, thats a good idea. I think I might get one of those and a smooth bellow. Where do you all recommend I get a smooth bellow from that looks good? Something in black would be awesome.

 

Home depot fernco bellow, it is in the plumbing section. It works like a charm and they are cheap too if you mess it up just spend another $8 and get a new one. Look in the external section there is a sticky that tells you what you need to know.

 

i have a rubber smooth bellow and my nozzle is on it. it works great! doesnt twist or anythng.
