Im after some information from people who have used Nitrous before in a small shot.

Im sending my rb30 in soon to be retuned which should net around 350kws at the wheels. Ive got a nitrous kit here that ive had for yonks that i got for next to nothing and wouldnt mind trying it. A few mates have had success with 40/60 hp shots which is what ill be doing. Hopefully ill get around the 380/400rwkw mark.

I will have a seperate fuel map through my computer for the nitrous.

Im interesting in whether its really necessary to have a purge system? If not what sort of delay can one expect before it kicks in?

My next one is whether im going to have issues running the nitrous (if so what issues) running without a bottle heater? I am in NZ (lot colder than AU) and the car may be used for night drags during the summer. The bottle will be mounted in the boot and i have considered a blanket to help retail heat?

Id love to hear from those who have used it before and the pro's and cons of both.

Thanks

bottle heater is a necessity IMO as it keeps the hit and therefore the NO2 tune consistant, i ran a heater but no purge as i used most of my gas on the street just being a jerk :blush: the softer hit without the purge helped cushion the shock on my auto.... for the first hit anyway :D i ran a 200hp kit on my old clunker but have done a couple of setups on NA 300zx's and supras lately usually 80-150hp.

Good to hear feedback like that. The one advantage of more cylinders i guess is the potential to run more nitrous.

Whats the best way in your opinion to have it setup? Eg on a button or switch on the throttle?

Is there also a correlation between drill bit sizes and the size of the nitrous shot. Have a few small hp fittings here (25hp etc) that are no use, and ive been told you can drill them out.

Any other hints or tips you would suggest?

You always want a wide open throttle switch (as a safety mechanism)

the bottle should be kept at a constant temp, very hard to do. this will keep the mixture correct. as the bottle gets colder the pressure will decrease and it will go rich. nice to keep bottle 850 900 degrees, in youre climate you will need a heater. also a guage on the bottle to monitor bottle pressure. apurge is nice to get a cool shot at the solenoid, happy times!!!!

the timing map needs to be tweaked with timing taken out. You are using a 'wet' system?

You can get yourself another 100rwkw with the fogger if you have the supporting systems and motor build can take it. Going from 350rwkw to 450rwkw might be fun :happy:

You can jewlers drill /file out the jets. All jets should be flow tested anyway to do it right. The NOS brand basic brass flare jets aren't always bang on in size and even NOS themselves at least reccomend flow testing them (very easy backyard test to do).

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
