I've been contemplating putting together a simple wet nitrous system for my L28ET build and I wanted to throw out a few ideas out to get peoples opinions. Firstly, let me outline my wants for the set up: 1.) It has to be clean. I've spent a lot of time making the engine as clean as possible; everything will be tucked and shaved and having a bunch of extra lines running all over just won't do. I'm not trying to hide the fact that I'm using nitrous, in fact the tank will be in plain sight. 2.) It has to be simple. I will hardly ever have the opportunity to use it (think 2-3 strip visits per year), so a fancy direct port, multi nozzle system is overkill to the extreme. It's mostly about having fun for me, not being super competitive. 3.) It has to be affordable. I have no problem spending money on quality components (although I can do without the purple anno) and I don't plan skimping on things such as the tank or solenoids, areas where safety is concerned. But as I previously mentioned, multiple nozzles and fancy extras are not needed or wanted. Okay! Now my questions: My ideal place to mount to mount the nozzle would be the core plug on the back of my intake manifold. I like this because it is simple to drill out, and install the nozzle with a couple of nuts and some rtv, the plumbing is short, and the solenoids could easily be hidden in the cowl area without being far from the nozzle.. Besides the ease of mounting, it is also 100% reversible where drilling holes into my shaved manifold is not! The question here is will this be able to evenly fog the intake chamber despite being opposite the throttle opening? I'm no fluid dynamics engineer, but images of pissing into the wind come to mind... My second choice would be to mount the nozzle in the intake pipe, post intercooler, where it comes through the rad support. I've already found a nice low profile nozzle that could fit nice and snuggly at all the right angles, allowing for the plumbing to be tucked along the top of the fender. The issue here is the distance from the throttle body, and the recirculating BOV in between them; there is also the issue of the bends in the pipe creating the opportunity for pooling. Will I have issues if the BOV opens and some of the mixture gets sent through a hot turbo? Is the nozzle too far from the throttle body (everywhere I read says 6" is ideal)? Are the bends a big enough issue to make this unsafe? I'm having Casey (SenzaPari) fab up a nice pie cut piece for this section and the bends are looking very smooth and gradual... Lastly, I'd like to ask for any general advice, or ideas that you might have. I know I'm not the first to go down this route, so if you've got an idea that you think fits my plan then please share it! Thanks HybridZ members, and sorry for the trademark long winded post!
I have mounted 2 buttons on my steering wheel and am not sure the best way to connect with wire. I am thinking about using a coiled cable, as I have seen before, but I would prefer to use a 'spring clock', which is how most cars connect electrical to the steering wheel in a discrete way. I am worried that a coiled cable could get caught up on the steering column when I turn the wheel all the way to one side. The steering rack on a 72 240z should be 2.6 turns lock to lock, which mean a coiled cable would have to wrap 1.3 times around the steering column. What do you think?
