NITROUS OXIDE ( nos / n2o ) advice forum

Hi all , new to the wonders of nitrous , just a quick fitting Q , I am struggling to fit everything in on my gsx1170 , can you fit the 8 way d block almost straight to the pulsoids , ie with just an inch or 2 between the 2? Also there are elbows into the top and bottom of the d block , does it go up a certain way? I am fitting a s/h kit but all the pipe , injectors are new from the wizards and the pulsoids have been refurbed.Thanks
Gary.

We can supply individual D-Blocks which can be connected directly to the Pulsoid outlets using a straight connector and that should suit your requirements.

I`ve got an old version of the Combined Radial Discharge 4 way D-Blocks you have on the site for £68 , is that not suitable? Just wondered if there was a minimum or maximum distance from the pulsoid to it?
Thanks
Gary.

That would be suitable but I thought you'd find it easier using individual D-blocks when wanting to mount directly to the Pulsoids.

If not directly mounted to the Pulsoids then you should mount all components as close as possible.

Thanks for that , got them fitted now ! the two wires from each pulsoid have been cut and need to be joined in pairs I believe , then joined up to the minimax and switched live ? Does it matter which pulsoid wire joins with which one on the other pulsoid ? and then onto the blue and orange wires?? Thanks
Gary.

PLEASE see the wiring instructions for the correct way to connect up the system here;

Hi again , I have already printed out that diagram but being an electrical numpty wondered if the 2 wires coming from each pulsoid had a right and wrong way round? ie. can i join any of the 2 nos pulsoid wires to any of the 2 fuel ones?
Thanks
Gary.

The Pulsoid wires are not polarity sensitive, so you can connect either of the 2 wires to either positive or negative supplies.

Thanks for help so far! got it all fitted , fuel flow from the petrol injectors seems slow , running lean . Have been told that the blue pulsoid I have mounted above a pink one is the nitrous one , and that they are different. The blue one came back from servicing with a fuel spigot in it and the pink one had the nitrous inlet in it. Thought i`d better check with you before dismatling. There are pics on the forced induction thread at oldskool.info . Thanks

That doesn't seem to be a legitimate link and after searching the site for Wizards of NOS, I found everything except your thread.

Sorry about that , its in the forced induction section of the infoboard , near the top !

Sorry , normally shorten to W O N , always capital letters

Found it and I'm going to deal with it on that forum (as soon as I get the login problem sorted), to set all those straight over there who think gravity isn't a good idea.

Unless im mistaken i think Tezz beat ya to it lol

Steve

So TJ is Tezz, well that explains a lot.

Just posted a few mock up pics on that Oldskool thread for my kit now with the seperate distribution blocks . Any thoughts?
Thanks
Gary

Back again , have fitted the seperate d blocks as per pics and tested the fuel flow. About 80 to 90 ml per minute flowing from the d block with a 150 jet, is this ok for 25hp?

LOL - I've just realised I posted a response to your previous post on a totally unrelated thread - LOL

The response was asking you to post a pic here as I'm too busy to get back to Oldschool forum (as much as I'd like to do so to set those FOOLS straight), so I can advise you.

Now I can see your mock up I can confirm it looks fine but I'd use a SLIGHTLY longer length of pipe between the Pulsoid and the D-Block.

Thanks , by that I assume you mean one that reaches the d block ! and not move the d block further away and fit a longer pipe? 80ml per minute ok for 25hp?
Gary et1170 .

Bit more done Turned injectors round in the carb rubbers and after an initial purge they are all injecting on the button at the same time May get it back together for a static test tomorrow . Supposed to be sprinting Sunday ! Would be nice

Looking good and sounding better than your initial report - however the fuel flow figure sounds rather low, so are you sure that's all it is?
What kind of fuel tap do you have, standard and was it on prime for that test?
Did you test at the injector outlets?
How full was the petrol tank?
Was that through a metering jet in the Pulsoid outlet and if so what size is it?

Thanks for your reply Trev. I have a duel output pingel tap so using one of the outputs for carbs and one for kit. Tested pre d block and at pipe ends before injectors. 150 jet in place. I think just under half a tank of fuel , will check later . Not the most accurate measuring container but definately over 20ml and under 25ml per 15 seconds. Will get a more accurate container and fill the tank up and post results.

OK well the first thing to do is remove the fuel jet and connect the pipes up to the D-Block and at worst flow test at the pipe ends that normally connect to the Venoms.

This figure is the MAXIMUM power you'll be able to make from your system.

Next you can fit the fuel jet and repeat the test to determine if there is enough fuel flow to match the nitrous delivery.
