Re: nos how much how hard

About $1200 easy to install.Usually used at full throttle.200 hp shot may need a wet system to be safe, which is more expensive as it sprays fuel in as well.A 100 hp shot on a EB with healthy exhaust pushes over 200 + rwkw..The hp rating is done by the size of jets into inlet manifold..Colder plugs and some timing retard when used also..

I think on the NOS brochure it says a Fox bodied Mustang running 15's will be in the 13's... They also reckon that usually u get a little more hp than what the jets r rated at.

Btw, how much can a 6pot take?

Normal rear wheel power on a slighly modified EB is about 120-130rwkw. The NOS can take that power figure to over 200rwkw.

For more info on NOS read:
http://www.holley.com/HiOctn/TechSer.../NOSTech5.html

Also remember that NOS and LPG are not really workable. It can be done i've heard, but it's really expensive because gas can't easily ramp up the fuel delivery on demand.

NOS won't fry your engine fast and furious style just running your car down the strip. (Personally I don't even give my time of day to that movie, or any movie as badly researched for that matter, where they pay someone out with "driving like a grandma, not double clutching on upshift like your s'posta"... )

Re: nos how much how hard

Nitrous Oxide (NOS is a brand) is not dangerous at all.

as xdc351 said it won't hurt your engine at all.

that said, what will is you.

if you don't drive n2o the way it should, or try and cram too much n2o into an engine, it will blow sky high!

if your running an EF XR8 (not sure) i'd personally suggest not running 200HP.

Maybe 100~175HP max without eng mods fine, but don't push it straight up.

and as ebxr said colder plugs and timing retard depending on how crazy you are making the eng.

Re: nos how much how hard

One thing to remember about N2O, is that is is not eh nitrous that burns in the engine, all it does is increase the engine's ability to combust fuel. Thats why you need to run a wet nitrous system once you get above the 150HP mark.
The Pils supplied with a nitrous kit, usually from 25 to 150, with a few in between, are supposed to rate HP increase at the wheels. ie 100HP shot of nitrous will increase RWHP by 100HP.
If you are serious about running nitrous, you would be silly not to put in a set of forged pistons. With constant Nitrous use, you will eventually crack a piston, and to a lesser extent, your rods. Nitrous will also find any probs with your rings in a hurry, so you will want a new set of those as well.
And as xdc351 said, i will not "blow the welds on your intake".
As for the question on how long will it last, that depends on 2 factors. 1- how much Nitrous you are using, and how big your bottle is.
Nitrous flows are as follows. For every 25HP shot, you use 1 lb per minute.
So if you are running a 100HP shot from a 10 lb bottle, you will get 2.5 minutes of use. So if your car runs 15sec qtr for example, you will get 10 full runs out of your bottle.
ie 2.5 mins = 150 secs.
15sec / 150sec = 10
10 full runs.

These figures are ideal examples, you will always get a slightly higher flow rate from your nitrous jets, and will not get 100% use of your bottle, so in the above example, you will probably get 8 maybe 9 full runs.

Hope this helps.

dyno run with nos

I thought if i put some figures up it might inspire you to go ahead with fitting nos.I did a dyno run with and without nos on my AU2 XR8. I have the 185kw engine in mine with extractors, twin 2 1/2" exhaust, cold air and uni filter with 150hp nitrous kit. I was happy with the results. 80kw gain for a $900 kit supplied, you cant bet that.
This link will take you to the run without nos, the pic with nos is the next one.
