NITROUS OXIDE ( nos / n2o ) advice forum

Morning all,

Well, this weekend I'm finally starting the installation on my ST Estate.

I have all the bits, well with the exception of a Venom Injector which I've just placed an order for this morning.

So, with the Scirocco I can use a microswitch to trigger the system along with the Minimax.

With the Diesel, will I need a TPS Box?
As this i'm thinking will determine where the throttle is and when I want to inject?

The ST standard is 155bhp, however it has had a few modifications.

Exhaust,
K&N Panel Filter
De-Cat
Bigger Intercooler
Superchips Bluefin

Estimate BHP although on the conservative side is 185bhp though I would expect just over the 190 mark.

Cheers

I've just sent you an email with regards to the Max Extreme and after seeing you have a Minimax already, I thought I'd better let you know that you trade that in against it if you wanted, although you would probably get a better price by selling it on Ebay.

Thanks Trevor,

The MiniMax is staying on the Scirocco, but the Max Extreme has to be the older version with the leads exiting from the rear and not the sides.

This is only due to the installation of where this will be.

I'll have another look and get another spare panel and see if it can be done with side entries of the Max Extreme.


Cheers

I'm in for a video update!

Hey Guys,

Been a while, but to be honest it's been quite a S**t year, even this year has been a dreadful start, but just got to keep plugging away at it.

Well, I purchased a DevilsOwn Water Methanol Injection to go a long with the WoN Kit, Started the install of the Meth and putting the cables through for both kits.
Meth will give 10-15% increase on Boost depending on where I set it to.
Normal Boost for the ST TDCi is 22.5psi with an over-boost of 26.5psi as far as I know, but looking at Torque it will quite happily hit 22psi.

Anyway, another dilemma, thought I had it sussed with positions but with the prospect of adding the DevilsOwn Water Methanol Injection system to it as originally planned I'm back to where to put the Injector.

I originally looked at positions on the Turbo inlet (Pos 1) and EGR to inlet (Pos 3 to 4), but to add Nitrous as well, then I have one Venom Injector to install which would normally be on the Air Intake side after the MAF or possibly Position 1 prior to the Turbo Intake.

So do I now go for 4 x 85cc DO1 Nozzles and go direct on the EGR Inlet Manifold which is ABS Plastic and stick the Dry Venom Injector prior to the Turbo at Position 1?

The angle for the DO1 85cc Nozzles mean they would spray directly into the Cylinder on one side of the port as there are 8 Ports (2 per Cylinder).

The attached Photo's are of the Engine Bay same as mine with EGR & Manifold labelled and the Intake showing 7 of the 8 Ports and Meth Positions.

Or.....do I have them all on the Inlet Manifold, I mean Cylinder 1 Nitrous and Meth???

I'm sure some have had experience of using both, if not I do apologise and this is not a plug for DevilsOwn either.

Oh here's the install so far of the Boot Install and the Controller which needs a little more filing to get it central.

Brilliant,

So I'll keep with the Original positions for Methanol with the smallest nozzle at 85cc at Position 1 and just prior to the EGR Valve.

With the Venom, I'll position that about an inch lower as this will jet into the methanol as the nozzle isn't angled like the Venom, that way it will mix nicely.

The photo shows the interconnector for the EGR-Intercooler Hose which needs to be cut, so the bottom port that was originally intended for Boost I can now reloate as my Venom Injector.





Excellent.

DO1 is 85cc/min at the Turbo Inlet
DO3 is 270cc/min prior to the EGR Intake

The original system is for a DO4 Nozzle which is 350cc/min so I'm pretty much spot on ±5cc/min

-------------------------------------------------------------------------------------------------------------

So the next question is how to work the best Nitrous to Methanol Ratio?

What would be the most beneficial Jet size for Nitrous?

It doesn't have to be massive, just a good all round size that will be well within safe limits and that will bring a smile

I know Trevor has said that Diesels are pretty much indestructible when it comes to Nitrous, but I don't want to go mad and if need can always go slightly bigger later on.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

and finally I never knew Won did a Water Methanol Kit?

That good,

If need I can get another Tube to drill and tap with the same thread as the Venom Injector so they sit inline, so that isn't an issue for me to do.

So all being well with the Methanol and we should achieve 200 - 212bhp, currently at 185bhp with all the modifiations, so if I start off at 25bhp Nitrous Jet then progress up slowly to achieve 250bhp then we should be safe without really over-doing it.

I may have to have it remapped again at this point although, I'm not sure how they would compensate for both not being in use all the time?

At least I know where the Nozzles and Jet is going which was causing me a headache!

Not now though

I wonder if Trevor knows if these products are still available?

The map I have installed is via a Handheld, it's manufactured by Superchips and called Bluefin, however I can take this on and off when needed without too much hassle but if it's a custom map to allow for the additional fuelling each time I switch WoN and DO on, then it may not be straight forward.

You can try to reach out to WoN by phone and find out if those products still exist.

Another update.....one day I will finish this, I promise!!!

As I'm on an Outage at the Power Station, what better way than to bring a homer in to do, well I might as well as were here for 12hrs / 6 days a week!

So here is the old glasses holder transformed into the Max Extreme holder now.
Just waiting to install 2 switches either side of the microphone ( 2 x NOS & 2 x Methanol) and a USB extension/socket from the Extreme.

Getting there....I know it's taking its time, Sorry

I can't see any of the images, thanks to Photobucket forcing users to buy a paid plan to host your pics. Could you attach the pics instead, please? I'd like to see your updates.

Can't believe they've gone that way, just tried uploading photo's but too big at the moment.

Sorry, could only upload a maximum of 3 images to that post so the other 2 are here.






Oh picking this little lot up tomorrow

I'd highly suggest using propane as your fuel source coupled with the water injection on that diesel. Your power capabilities will be MENTAL! Otherwise use alcohol or use the nitrous side only as diesel cannot be injected at the port.

The plan is to inject Water methanol in via 2 places, below the EGR (270cc) and prior to the Turbo (85cc), then inject Nitrous behind both Methanol Injectors to aid mixing.

The other aspect is that I don't want to go overboard with how much Nitrous I'm planning.

Ideally, the Methanol will be 10-12% increase along with maybe 25 shot working towards 50 shot, what happens after that, who knows, i just want a big smile

Well, the breakout lead is here to bring the USB Port from the MaxExtreme V2 to the front (In case it's ever needed).


Picked all the WoN bits up from Leicester yesterday, really got a bit of a bargain with that lot
The kit has done less than a 1000 miles before it was stripped out for some reason, it was in an Audi TTS which was being broken on the front yard?

Well, brought the stuff I bought yesterday into work and thought I'd power the MaxExtreme V1 up as well.

Just got to see what jetting sizes were used........50 & 20 so standard set up

Well, a little bit more done for the ST Install, well might as well make the most of being on shift!

Just need to find a little Mini USB A Dust Cover from eBay now.
