Right... erm don't get mad....

 

now this ain't exactly a 300zx question... that's doin' fine as standard and to be quite honest at 14yo I don't think the turbos would take NOS.

 

However I've been thinking of sticking it on my v6 mondeo for ages. And I figured there's bound to be folk on here with experience with Nitrous (whereas on the mondeo groups they seem 'pushed back in their seats' with the incredible 170hp of a standard mondeo v6 (think... getting burned off by an XR2i and you won't be far off with the 'incredible' speed of the standard mondeo.. :-) )

 

so, thinking of 75hp shot, wet kit. seems like they can be had for 4-500 quid. Plus 150 quid fitting.

 

Questions:

 

1) seem quite easy to fit. is it a job anyone here has done themselves ?

 

2) if you've got it, how often do you use it ? at 75hp and a 10lb bottle, it will last for about 90 seconds... now I know I'm just using it for 5-10 seconds a time.. but still... at 50 quid a refill it's still quite expensive... is it worth the hassle of finding a supplier of industrial big bottles (boc, linde,etc) and doing it yourself ?

 

3) don't suppose anyone has ever managed to get insurance for their NOS car ?

All I can say is...

 

Why spend it on a mondeo when you could get way more permanent power on the Z for the cash?!

 

Paying all that money for the system then £50 each time for a minute of acceleration that won't be as good as the Z anyway and will probably just spin the wheels all over the place.

 

Or is your Z already modded to the max and you can't spend your cash fast enough?! LOL

300 horses is enough power for the Z. It gets the tail out and

blows off everything else on the road (in suffolk anyway).

 

If I want REAL speed I go out on my fireblade.

 

The mondeo would benefit more from 75hp than the 300. And if

it gets buggered I won't be crying my eyes out for weeks :-)

How about fitting turbo or supercharger?

NOS costs 400 quid. another 150 to fit it.

 

you can't get better bang for the bucks.

 

turbo conversions would costs a fortune, and be lucky to give

as much power.

 

anyway, NOS sounds cool.... you can't beat a wee activation toggle switch on yer dash :-)

Just don't see the point of it myself.

90 seconds power for £50 ish...

Overtake 2 cars, 2 races from the lights and it's gone.

Then wait until the weekend to drive somewhere to fill it up - if you can afford it on top of the fuel! LOL

 

I only know 2 people who have NOS and after a couple of months they stopped using it.

 

300bhp in the Z is nothing, get it over 450bhp and it starts to be much more fun!

For £500 on the Z you could get a good boost controller and ECU upgrade giving 70bhp ish

I am in the middle of fitting a 100bhp Nos kit to my 300 (its an NA) it is easy to fit a standard kit, which will cost you in the region of £500.

 

The problem that i had with the above is that I dont fancy chucking 100bhp/ 200ft/lb of torque through my back wheels at one hit, so am fitting a progressive controller (allowing a preset build up of nos, over a predetermined time) (also its another gadget) this has the benefit of controlling the power and making your nos last longer. The 11lb bottle i have is said to last around 60-90 seconds, doesnt sound a lot I know, but factor in this: a reasonably fast car will do a standing 1/4 in 14 secs, Nos is only used at wide open throttle, so that is between 1 1/2 - 2 miles on full tilt Nos and WOT, the controller cuts in between 30-60% through to 100% over a time of 2-9 seconds, which again is increasing your FT/WOT time.

 

I would ask how many people on this forum regularly use WOT for 1 1/2 minutes over a distance of two miles, not many I would suggest. Road conditions/ traffic dont allow it. If you are going somewhere like a track, you make sure you have enough gas (an 11lb co2 fire extinguisher has the same fittings as a nos bottle and is a dam site cheaper) if not it is a little surprise for the traffic light grand prix laddos.

 

Having said all the above, i have been looking into the cost of a cylinder from BOC and the filling kit is about £30.

as jock says.. 90 seconds of gas will last a good while. I reckon over a month. you only use it when you really want it, and even then only for 5 seconds or so at a time.. it's more for faster in gear 40-70 type accelerations. you shave a few seconds off, and have a total NOS time of 5 or 6 seconds.

 

so gas lasts a fair while.

 

Ideally, you want a big cylinder to do you own filling. BOC won't rent you them as they know what you want them for and historically don't supply for car applications. I'm hoping maybe Linde or Air Products are less bothered about end application...

 

Jock, let me know how you get on with the kit. Progressive would be nice. how much was your progressive controller ? At the same time I really fancy the sheer all at once promise of NOS.

 

My last 2nd car was a saab 9000 2.3 turbo. Standard 220hp, 250 ftlbs torque. But the wastegate on the turbo was buggered and it was overboosting massively. This had to effect of pushing the thing towards the horizon like some sort of stream-ramp on a aircraft carrier - it was awesome. Must have been pushing 260+ hp.. went through 3 engine mounts the kick was so brutal... but fun fun fun... the look on the faces of Lotus Elise/Porsche drivers/etc when this old rusty 1990 peice of shit saab beat them up to 100 then left em for dead up to 150 or so.. hehehe.

Stu, the progressive comes in at £300, with all the various bits and bobs my kit cost over a grand (there is a second set of injectors for the zed).

 

Have been casting a sly glance at my S70 volvo (daily driver) thinking it would benefit from a shot of laughing gas.lol

 

Was thinking of ordering the gas through my company, that way i could tell BOC it was for some fancy welding process :)

good idea on ordering it through your company. But don't say it's for a welding process. no welding process uses NOS as it's an oxiding agent, precisely what you don't want(I used to be a salesman for BOC ages ago). Best to say you need it for some industrial process (as you don't want medical NOS, and they won't supply that to you without a medical gases licence).

So when is the ideal time to upgrade to NOS on a TT 300, is it only after fitting massive turbos and strengthening engine?

The only time i have heard of nos on a TT is for filling in any turbo lag, but wasnt aware that the TT suffered from that.

 

If you are going to stick it on "top" of the turbos, you are going to need some internals done, pistons, conrods, stronger clutch done to handle the power. But, as i said, mine is an NA, so I could be blethering :)
