Ok. Where do I install the nozzle?
 

I'm most likely going with a small wet shot of nitrous in the near future (25 - 50 HP jet, which will result in a slightly higher HP gain due to the fact that I'm already running 10 PSI.) Problem is... I don't know where to install the nozzle! It's a wet shot, so I gotta get it after the MAF, but before the TB. That doesn't leave me much room and I really don't want to drill and end up having it in the wrong place. Any suggestions for nozzle placement in a boosted engine? here's a pic of what I mean (as far as how little room I have between MAF and TB. Sorry for the crappy quality... it's a cellphone pic.

Why is the MAF so close to the TB? I would move the MAF farther away and put the nozzle between the MAF and TB.

RE: Ok. Where do I install the nozzle?
 

It's that close because of the Procharger. With the way the tubing runs, it would be a major pain in the ass to have it anyplace else. It wasn't an issue when I was running my CAI and had all the room in the world, lol.

You could consider modifying the before-MAF pipe, cut a section out, and add it after the MAF. That would give you plenty of room for a nozzle.

I actually did think about that, but then i got scared and changed my mind real fast, LoL. Normally I wouldn't be concerned... but I'm not good enough to do it myself. And even if I did have someone else do it, I would be concerned that it wouldn't be a clean enough install. And with 10 PSI of boost, the air would find any weakness (i.e. leaks) in the modification and it would F up the whole system.

This is kind of the reason why I was going to run with a 25 dry shot.... so I could place it before the MAF. But I'm a bit scared a dry shots now, even if its only a 25 shot. Afraid to run to lean or stress the fuel to its limits.

Gotcha, I'm with you on the weld quality thing, especially with 10lbs of boost. What people do with Grand Prix GTs/GTPs is they drill and tap the TB-this is an option.

i would just use a plate system. most wet kits are plate anyways. it mounts behind the throttle body.


i see a new block in your future with any kit.

RE: Ok. Where do I install the nozzle?
 

Never thought of that option...that would be easier.

Yeah..when it's time for a new block it will be a 351W anyway :)

RE: Ok. Where do I install the nozzle?
 

okay, I can't seem to find a plate anywhere that would work. I found some kits out there that come with plates, but those are non-adjustable and come at like 150 HP. I just want a simple plate that I can tap a nozzle into. Am I going to have to buy a solid spacer and drill it myself?

there is fixed 125's and adjustables (40-80) and 50-175. you can put any level you want as you just need to buy the right nitrous and fuel jets.

Just go to a smaller head pulley, problem solved!!;)
