firstly im not 16, and im not a numpty. (i also know n20 isnt "forced induction" but didnt know where else to put it)

however i have zero experience with N20 kits on minis. im just turning over a few ideas in my head, and have now turned my thoughts to this.

please dont laugh at what might be silly questions.

with a "wet" kit, do you need to already be using an electric fuel pump, or can you use the mechanical pump? i wasnt sure if a mechanical one would supply enough pressure.

i did read something about about the n2o bottle pressure pressurising the fuel goig to the solenoid? but i think i may have been mislead there?

basically im looking at getting a kit for my 1310 with a single hif44, so if anyone can offer a rough instalation scheme i would greatly appreciate it.

dont know the answer to your question but i would suggest giving the Wizards of NOS a ring ad asking them, who better to ask than the experts?

always found this website a fountain of knowledge.

www.nitrous.info

full of great diy info and builds

^ lmao ignore that Burgerman Idiot. Wizards of Nos is where its at. Have a read of there info pages on their website (rather than the forum, though check that too). A wet kit needs fuel supplied to the injector under pressure, it doesn't matter how. But you will need to establish whether the mechanical pump can supply enough fuel - my hunch says it will struggle, and regardless an electric fuel pump would be a good reliability upgrade anyway.

Re. the Nitrous bottle pressurizing the fuel, I've no idea where that came from but its wrong lmao.

Basically you run 2 fuel feeds, 1 as it is now, a permanent normal driving feed. And the second runs to the N2O injector to be injected with the N2O. You can get away with a mech pump on the normal feed but really you want a high volume elec pump for the N2O feed. It's a great performance upgrade, one I am putting on my 1310 build.
You will get people tell you your engine will explode and melt itself. Not true, if installed properly it is not more a problem than forced induction and WILL NOT melt your engine.

My advice is go with a wet kit as you said, don't be tempted to run a dry kit!
Minisport sell the full kits I think, and don't over do it with a huge injector!

You can't run a dry kit on a carb anyway. A dry kit means just N2O is injected into the engine, and the extra fuel is added via the injectors on an EFI engine. And reliability shouldn't be of any concern whatsoever, IF a WON kit is used. They even offer a fitting service.

thanks guys. i will cruise through some of those sites you pointed out now. however i must admit i did see a site last night that talked of building your own kit. most of whats required im pretty sure i can get from a company local to me called "cougar hose and hydraulic" plus im quite pally with the one guy there who has a mini.

installing an off the shelf kit will be no problem im sure, and im sure building my own wouldnt be too tricky either, as long as i can get some good info from the other sites etc.

off for a peek now.....

WON do all the bits you need to build your own kit. Get good quality switches and injectors, pipework, pumps and bottles can all be got fairly cheaply and won't effect the overall running of the system.

[cradley-heathen]

i took a look at the solenoids on their site and i could only see some that were £180 ish each? i would prefer to buy some proper solenoids to be honest, and just source the rest myself.

[HARBER07]

I advise the use of a WON bottle valve even if you don't use their bottle, along with the solenoids. Primarily for a safety point of view. The Blow off discs used on other bottle valves are EXTREMELY dangerous when they blow, and the solenoids are maintenance free. The latter shouldn't need explaining. Depending on what shot you go for (I guess no more than 50 on an A series?), the rest you should be fine to cobble together with any generic stuff. Any more than that and you really need their full kit to ensure a safeguard to your engine.

I myself have just been looking at the idea just as something i havent seen many others do surely without uprating many of the engines components e.g straight cut gear box the possibly almost 100bhp increase will cause damage also i think you would need to have electronic ignition so that your advance adjusts as you boost and i did see a kit that interacts with the TPS i think it is rather than the MAP sensor so that it doesnt run too rich or not rich enough but as i am no one to have any real knowlege on this its just what i have come across and may be useful to you good luck :)

This is Nitrous Oxide pal. The above should be common sense for forced induction.
