I checked out the websites for these companys. Dragon Autosport's site is still under construction but Highpower's site is pretty good with lots of techy info. Called the guys at Highpower and they were very helpful. They reckon they've done a few Skylines including a 900hp(?) one with a 250hp nitrous boost (I'm sure someone in this forum would have heard about that!). Anyway, the kits cost between about £300 to £700 depending on boost required. Seems like a cheap way to increase power at least until I can afford new turbos, injectors, cranks etc.
It is a pity you are so far south, as a mate of mine is at York Dragway this Sunday with his white R33 that has a NOSWIZARD kit and 75 bhp jets giving 150 bhp! on it, with a standard engine...
Will be interested to see what times he runs!!
Will keep you posted...
BTW It is forcast thunder storms as well so should be interesting!!
I'm almost certain that the way forward for now at least is to fit a nitrous kit in terms of BHP per £. I'll probably be looking at purchasing it in the next few weeks. Maybe you could let me know what kit you've installed and any tips you might have regarding fitting etc.
At the risk of sounding very controversial (and I've had this said to me before), if you can afford a Skyline you should be prepared for the costs associated with properly tuning it. Massive power doesn't come cheap, when you look at the kind of money Guy, Dirk, Gary, Glen etc have spent on their cars (and plenty others on this board) for a reliable, genuine tune - it really puts NOS into perspective.
Putting NOS in a Skyline, to me anyway, seems to be to be a bit like buying one and then sticking bits of fibreglass on it. ie. its totally the wrong way to go (in my humble opinion anyway)
I should qualify the above by saying that I take home nowhere near the kind of money that some of the people on this board do, so I haven't got an elitist attitude or anything, but even with my limited means I can appreciate how much genuine power costs.
Each to their own however, just thought I'd add my 2p.
Let me also qualify my previous statement by saying that i DO NOT know the cause for the engine problem on the R33 and i am currently investigating this issue...
Therefore i can neither say that it was or was not the NOS to blame in this instance...
As far as power goes i have an ALL STEEL engine myself with Nismo bearings etc and has cost me a fortune to build, by working very very long hours!!
But i would like to say in the defence of NOS i know a few other Skyline owners that have used NOS for well over 12 months now with NO problems what so ever!
I would agree with the fact that a progressive controller does help as well!!
I think nitrous is safe as long as its used in a sensible manner, like many tuning products available
The problem with nitrous is that is very easy to get carried away with adding more power (much like those dodgy old bleed valves you might have used on a doggy old RS Turbo, quick turn of a bolt and you've got 2bar and a melted engine ).
on a NOS setup, a 5 minute change of a set of jets and you can potentially double the power input available.
NOS isn't the dangerous thing, its the users hunger for a few more bhp and pushing it a bit far is usually the cause of engine failure
On the other side you have Drag racers which have various budgets ranging from smallest to big sponsors and as well as tuning in the conventional terms they run nos.
It's not the nos that is at fault it's to do with it's application, else it would not have been used in the 2nd world war by planes.
If you want to run Nos in large amounts you have to prepare the engine correctly. If the amount you plan to run is relative to the size and type of motor and is done correctly you will have nothing to worry about.The increase is instant on a one shot set up, that means at just over 3000rpm you could have your engine's output + 150bhp and 150lbs of torque.. if you go too far on std you can have problems with a one shot setup.
My nissan has caused me no problems on NOS, the skyline in question was running a shot that made + 150 bhp, at that level of power can anyone be sure there was capacity in the pump to make that power and were the plugs changed for colder ones or just std?
Tuning is all the same no one thing has an independant effect on an engine just levels of it's effect on things.
In it's simplist term think of it as running a bigger than biggest intercooler with water injection and special fuel...........that,s NOS.............-128 deg temp, anti-detonant and gives power too.
I like nitrous, and the amount of power that can be acheived at a reasonable cost. I think there have been so many scare stories accciated with the stuff that its got a bad name...
ive come from a bit of a Renaut 5 turbo background, and have had a big aversion to turbos... the bastard things just kept on disintegrating... - now, if i was to say that all turbos were the work of the devil and that you shouldnt mess with them... id be publicly lynched!!
abused, both ways of increasing power (turbos & NOS) have the ability to create LOTS of power, and equally the ability to run up huge repair bills, but tuned to the application, and used 'sensibly' both are hugely viable ways of getting more oomph...
but saying this, ive never used NOS, but the more i look in to the stuff the more it does make sense...
