installing NOS on a 98 coupe(hatch) ??
I have heads,cam,headers, Z06 upper intake and Ti Catback and a cold air intake. I was thinking about putting a 100 shot on my car but i've NEVER dealt with NOS before. The car has 97,000 miles on it... can it handle this? What would have to be changed out in the fuel system to support this? Car dyno'd at 395rwhp with these mods.
Where is everyone mounting their bottle in the hatch without interferring with the removable roof panel in the back?
Thanks!
Shannon

Thanks! Good info...
i have my car tuned by a Carolina Auto Masters and would NOT be running the NOS before he retuned it. I was just wondering if the stock fuel system can handle it and where people are putting the bottle in a hatch car?

I have NOS on a 98 as well ( automatic )---I only use a small shot 65-75 HP--I have EFILIVE and logged several tables to see what effect it has on the fuel system and spark--I have a stock fuel pump--stock injectors . System is wet
At WOT the data logger shows that the fuel pressure does not waiver at all with the NOS activated--and I am getting NO KR either with 24* timing in the RPM ranges where the NOS is being used--I do use 91 oct gas as thats all we have in calif and then mix it with some 100 oct unocal to pick it up to about 94.
I would reccomend a window switch---a low fuel pressure saftey switch --and an electronic TPS switch to work with your fly-by-wire thot. body-Mine is set to come on at 4200 rpm's and off at 5800. So no NOS is being used during the shifts---with some leway---I bought all the stuff from Dyno tune--very happy with them--
Any more than 75 HP would require pulling some timing either accross the board or with some kind of device actuated with the NOS
My bottle is right behind the pass. seat within reach of the driver

EFI Live
If you have a 99+ pcm in your car, you can use EFI Live to run a seperate tune when you activate a ground on a pin on your PCM (IE you flip a switch and your factory PCM switches to your NOS tune), you can do a 100 shot safely this way, and its rock solid as long as everything is installed correctly.
