NITROUS OXIDE ( nos / n2o ) advice forum

When will these be available to us regular guys?
We're taking orders now and we hope to have them despatched within 14 days.

It looks like a great concept.
Glad you like it. Unfortunately it seems some people can't see the significant differences between the Spider and the Speedtech plate, so I'm pleased to see you can.

The only thing the Spider has in common with the Speedtech plate is that the nitrous is discharged from the centre but there is a world of difference in how that's achieved between the designs and anyone who can't see that is missing the importance of this whole new concept.

BTW, welcome to my forum.

is there a list of what domestic 4bbl these will fit yet

Could this concept be installed as a "hidden" system in a single plane V8 manifold from the bottom?

Hi guys,

I've just had a pic sent to me.

It looks like someone else (some years ago) has tried to use the same core concept that the Spider is based on - 'central discharge' rather than spray bars and all credit to them if they'd done it correctly - which obviously they didn't when you see how uneven the plumes are.

Now here I was thinking I was only the 2nd person to use it, when in fact I could be 3rd or even 4th. BUT at least I'm the 1st person to get it RIGHT!!!

The unfortunate thing is that some people who are aware of this plate, 'think' it offers 'the same' features as the Spider, when in fact if they bothered to read the features listed below they should realise that the Spider takes the 'core' concept to a whole new level of performance.

Now if somebody would like to explain to me how the Speedtech plate or any other achieve the following benefits offered by the Spider, I'd be interested to hear about it, because if so I must be missing something and I wouldn't want to be making any false claims for the Spider.

1) ANTI-REVERSION nozzle location.
2) EQUAL distribution to all cylinders.
3) DIRECTIONAL discharge which can be adjusted to optimise the exact point of injection relative to the port.
4) INDIVIDUAL cylinder fuel and nitrous jetting.
5) Delivers MAXIMUM liquid nitrous density.
6) MINIMISES flow losses caused by poor flow paths and turbulence at the exit.

Just as with ALL my products the secrets are in 'the detail'.

One final thing about these other plates, I'd be VERY WORRIED if the Spider delivered such POOR distribution.

The plumes at 11 oclock, 4 oclock and 5 oclock must be flowing less than HALF the plumes at 2 oclock and 8 oclock plus I can't see more than 2 plumes that even come close to flowing an equal amount!!!

It's also clear that there is so much loss in density and so much turbulence at the exits, that the plumes turn to gas less than an inch from the exits, so not much charge cooling going on there then!!!

Anyone care to comment? Would the owner of the plate like to step forward?

Regards

trev, is there an optimum distance from the manifold floor to the nozzle outlets of the spider or is that not important.
It's not so much to do with the distance from the manifold floor, more a matter of the nitrous nozzle position relative to the runner height, although in some instance they will be one and the same measurement. The important thing is to have the nitrous plume enter the runner central to its height and width for the following reasons;
1) to achieve optimum runner filling
2) to minimise reversion
3) to minimise the nitrous impinging on the runner wall, creating unwanted turbulence

The main method of optimising the position of the nitrous nozzle will be carried out in house, prior to despatch of the Spider. Whenever possible we will supply the Spider to match the dimensions of a customers manifold, however as you will see in the pictures that follow, it is also possible for the customer to optimise the injection point by contouring the Spider legs to exactly suit their manifold.

Also, are the nozzle's(legs) standard in length or do they vary depending on manifold configuration.
For ease of installation and to ensure the Spider was capable of fitting a wide range of manifolds, we made this first batch with relatively sort legs but ultimately we intend to offer a range of leg lengths to suit different applications. Having said that, we still have more testing to do and I believe it may turn out that there are some benefits to using legs of this length, in which case we’ll stick to what we have.

We’re constantly rethinking, redesigning and retesting ALL our products in the search for further performance gains, so don’t be surprised to see more changes in the future. Quite often the production and test results of a new component, lead to a chain reaction of thoughts that then leads to even more radical designs.

When will these be available in the US?
They will be available in approx. 2 to 3 weeks, we're just waiting for a quantity of parts to return from the anodisers.

Can you customize the main body to drop it into the manifold plenum further.
Yes we can but that would add to the cost, because we'd need to make a couple of 'special' sections for you.

I am going to try to get you a picture of what I described about the 2 inch 4150 to 4500 flange carb adapter/spacer.
I think I know what you're talking about but a pic would confirm than and help anyone else appreciate what's involved.

I would need a body 2 inches longer.
Before we decide how long it needs to be can you measure from the carb mounting flange to the centre of your runners, then I can determine 'exactly' how much extra length is required.
