Nitrous

[BigNige]

Gotta be cheaper than a turbo or a supercharger and definitely cheaper for the times you can actually use the extra power.

Who has, where from & how much?

Make sure you do the proper research, if you get it wrong the consequnces will be huge. As well as the basic kit you're going to want a progressive controller or window switch, a bottle heater, a purge, a blow down tube (if you plan on drag racing it). I would go for a wet kit with no more than a 150 shot, you may have to get whoever tuned your car (Wortec I think) to check your airfuel ratio and you may have to remove a few degrees of timing just to be safe. You could go with Wizards of NOS if you don't want to import an LS1 specific kit from the USA but its your choice. I think (not counting the other bits like a stronger clutch) you should budget about a £1000 for a complete install if you shop around.

More edit: You also need a nitrous pressure gauge and a fuel pressure safety switch

Also I would do headers first as well as nitrous loves to breathe....

EDIT: You'll also need some NGK spark plugs as well...

True but.........use an established company who know what they are doing. Wizards of NOS are my choice, or Monkfish Performance. Yes you will need a wet kit but no purge or blow down tube necessary. Standard fuel system fine, no need to change timing, all you need to get is one grade harder plugs which will not affect 'normal running'. My twin bottle system with a Maximiser progressive controller, bottle heater and twin solenoids cost around £3K from Wizards of NOS. The installer will set it up, no need to go back to your tuner. Will definately need an uprated clutch, preferably with a lightweight flywheel.

Not necessary Dan but will give slightly more power.

Again no you dont Dan. A guage is obviously handy to see contents but not a 'must', additional fuel pressure safety switch not required.

[Dan_S V8]

A purge isn't necessary but if you want to run at the track you will get a slightly bigger 'hit.' Some tracks (at least in the USA anyway) require a blow-down tube for dragging...

Nitrous Express make a very good kit for LS1's and are a very well respected name and you'll be able to get all the necessary bits in their GenII upgrade kit. I think its about $600 for the basic kit, $250 for the upgrade kit and $207 for the progressive controller. Add $250 for shipping and bobs your Uncle.

OK so those bits aren't necessary but it is far better to be safe than sorry IMO and if you're serious about running it at the track you're definitly going to want to know how much you've got left in the bottle, JMHO but if you want to take short cuts that's fine by me...

also if not enough pressure is being supplied from the bottle with a wet kit it could create a lean condition (=boom) so if your using a bottle heater you need to be able to see where the pressures at.

Trust me when I say a purge kit is necessary only if you are a 'Fast and Furious' fan

I have had a quite a few NOS kits including American ones I fitted myself. The best advice I can give is that it is far safer........and easier........to use a UK installer. Its not Rocket Science but if you get it wrong.........

[Dan_S V8]

Trust me when I say clearing your lines before you do a run will provide more power than not... Ok so if you get a coloured machine gun type purge it's not really going to help!

Not nit picking Dan........trying to save peeps money. A purge system is NOT required. I have used NOS on a Funny Bike and a Street Altered Car plus quite a few road cars.

[oe_cosgrove]

If anyone is going to do their own install, or should I say brave enough LOL , I have a fairly comprehensive pictoral record of an HSV install if of any help.

[Dan_S V8]

Nah its cool, I understand what your saying. I would be interested in the HSV pictorial install if its going, could you email it to me on danielsteeneATyahoo.co.uk? Do you have a wet kit or a direct port kit?

Thanks,

Dan

[oe_cosgrove]

For information the pressure guage(s) would be mounted on the bottle(s). Which would be in the boot. An in-car guage is not offered as part of a Wizards of NOS kit. The rule of thumb is that you switch your bottle heaters on for 30 minutes before using it in 'cold' weather. I never use use heaters in the Spring / Summer / Autumn and have had no problems.

Will do. I always use wet kits.

[Dan_S V8]

Thanks a lot

Just thought, 250hp is a well big shot for even a wet kit, did you have to tune for that at all?

Wossa wet kit?

Sounds like something kinky

[oe_cosgrove]

Wet kits use injectors to introduce fuel and nitrous mixed into the manifold. Google Wizards of NOS, their website has excellent technical info.

No, it is installed as a 'self-contained' system independent of the engine management.

First step is insurance, many wont touch you with nitrous. Fluxy do my Dakar kit which is totaly unlimited - anything goes, but no nitrous.

I also suspect you will chew your way through £50's worth of gas rather quickly if you were using on-road. I was reading an article at autospeed saying you can expect 2 minutes worth of fun per bottle - that's really not very long at-all is it?
