Neilo

Soz forgot you had to register !!

Neilo...You do know your bottle is incorrectly positioned

Should be mounted front to rear on an incline as to get nitrous flow in all circumstances

doppelganger

minimum 15 degrees highest at the front that way when you are getting low the nos is pushed to the back and easier for the syphon tube to be fed .

might just be my opinion but if your fogger nozzle was in the centre at the top the bias wouldnt be towards the right bank of engine(other input appreciated)

I was thinking about mounting mine on the underneath IC, just before the outlet to the throttle body so that it flows evenly through.

The only problem I can see is the limitations of space.

Just one question for Neilo, do you simply tap into the fuel line at the standard pressure or does the pressure need to change? I already have a 255lt Walbro fitted.

doppelganger

ive fitted a cold fusion kit on an impreza tapping into the fuel line has been fine (fitted over a year now) just check all your fittings on that kit cos the one we fitted nearly all leaked fuel and nos even the valve to bottle seal

Nick Read

ROFL my thoughts exactly...try 240bhp through a FWD Clio then tell me about problems getting off the line cleanly. I ended up running 13.3@107mph in that, and my 60ft times were never less than 2.3...

Nick Read

It's old school technology - tap into the fuel line as it is, you alter the physical size of the fuel jet to fettle the amount of fuel you mix in with the nitrous. Might be an idea to have at least an AFR meter on the go, perhaps get it all checked over with a decent gas analyser up the tailpipe to get the mix bang on.

DannyBoyTurbo

Just to let you all know that 150bhp jets with no controller is the best way to go. Its the most fun I've ever had in the scoob. Only downside is some serious whiplass.

Engine lasted about 2 full bottles aswell before the piston hit the bonnet ;o)

Neilo

yes in that pic the bottle is mounted wrong, ive since changed it but you get the idea....The bottle is not flat, it is on an incline...thats just the orientation of the pic throws you off...

the coldfusion kit comes with matched NO2 and Fuel jet sizes, so you cant really get the fuelling wrong, which is great. You just have to T-off the fuel line after the fuel filter and thats it....

LOL @ DannyBoy

Neilo

i remember seeing the pictures.....did you ever do the 1/4 with that??

ZEN Performance

they do bog down quite easily unless you're prepared to give it some serious abuse.

Neilo

its hardly the 4wd systems fault though...that would happen in any car surely..

doppelganger

i still say that if i can run 2.2second 60ft times in a vw transporter pickup with only 135 bhp !!.maybe its not putting your foot in when it counts, i can see why the 4wd boys dont want to side step the clutch at 4500rpm probably need to be able to drive home.perhaps you need traction bars to keep the power down(maybe its you i keep beating at the lights on the way back from the builders merchants ).

ZEN Performance

Where many 2wd cars will allow the tyres to spin, 4wd cars may not. Although lots of wheelspin isn't good for launches, a little can make life a whole lot easier. With sticky tyres on a sticky prepped track, I can still bog from a 5500 rpm launch at full throttle and 0.5 bar of boost. Doing something like increasing tyre pressures, or reducing diff lock to allow some controlable wheelspin can improve 60ft times on very grippy tracks (or save your clutch!)

Paul

Neilo

that is true....i suppose the equivalent problem in 2wd is if you have an LSD....or traction control.

doppelganger

nice to know someone knows where im coming from with the bogging down thing.

Just re-read this and was wondering about what rpm yours kicks in at? I thought 3000 rpm was the minimum for safety?

I was hoping that I could run a 25 shot from 2000rpm. What do you think?

If I have a walbro 255lt pump and a standard reg, what pressure should the system be running at?

Also, after speaking to Andy, he says that an early shot of nitrous that blends out as the boost comes in shouldn't require timing adjustments, but if it did I have the commander nearly mounted in a custom display in the dash so can do a global retard.

Mitchy260

I wont activate mine until 3000rpm but its on a controller so its probably about 4000 rpm that 100% of the nitrous flow comes in! Take it upto 7000rpm so a good 3000rpm nitrous range.

Nitrous gets safer and safer the higher up the rev range you go, i'd say 2000 is a tad to early. Even for a 25hp shot!

I know on the wizards kit you do not need to worry about fuel pressure and flow as the metering jets sort that out. As long as you get the correct ratio of nitrous/fuel then thats all you need to worry about.

Ah, forgot to say mine is the coldfusion kit

I got a 1.5s 60 foot time and that was my first time on the strip at the Pod. I suppose my 'real' 60 foot time must have been 0.5s, as I must have bogged down for a second or so...

Anders

Neilo

i doubt it mate....i dont think pavlo does it any quicker than that so i doubt you "bogged down"

DanTheMan

My bro has just had a WON kit fitted to his Civic TypeR plus a remap, hes got loads of Mugen goodies too (intake & exhaust) and is now pulling 252bhp at the wheels, its like **** of a shovel but its carefully mapped to come in at 3-4K in the right conditions but I can tell you torque steer in triple figures = brown pants

1190 KG's means a fantastic power/weight ratio, I reckon it will frighten a lot more expensive machinery

Neilo

has he run it yet like that? i went up against a nitroused CTR which claimed to be the fastest NA one in the UK and it ran a 13.5 i think at the time?

DanTheMan

He's not done a 1/4 yet but I'm sure he will, he's only been through a few bottles so far and is just getting the hang. The remap and mugen parts made a huge difference anyway but the NOS adds a different dimension once its up to speed.

Activating the NOS toggles in a different ignition and fuel map, I have seen the maps on his laptop and they are top notch, he can even vary his VTEC parameters.

Focusbird

I've got a WON kit on my car (ok, it's not a Scoob) with a progressive controller and 50bhp jets. The only advice I would give is not to let WON themselves fit it (ie. Trevor and his "boys" in Doncaster), I paid someone else to do the job properly after they made a complete hash of it. Plus since then, they've denied ever having fitted nitrous to a Focus to a fellow club member I know

Never had any problems with the kit so far though
