I happened across a mention by Tom (YMMOT04) and OneSweetRide that mentioned NOS on a supercharged motor. It'* feasible and possible. Check out threads by Dirthead Racing. He did it and while he mentions there was a lot of tuning and a motor that launched because a vacuum line popped off. He was overall successful with it.

This is all I could find https://www.gmforum.com/showthread.p...ead+Racing+NOS Although it looks like a lot of his posts are missing. This isn't something that would get done any time soon, but I do like the set-up they talk about in this post. I do have quite a bit of work to do before I can even think about adding NOS.

I wouldn't even consider it until I had forged slugs in the motor, maybe a set of powdered rods backing those. That NOS requires, like Bill said, almost perfect tuning otherwise the motor will go south in a hurry, if you can get everything squared away you can run a little with what I assume to be good results.

When I had my turbo cars (AWD Mitsu Eclipses) I helped setup a 100 shot on a stock motor to help the launch, and the motor never had any troubles with the extra kick, because we spent ALOT of time tuning and had the computer setup to control the nitrous, so if the motor went too rich or lean or had any knock, the nitrous would shut off.

Which brings up another question. Is there a program or device out there that can control the NOS, shutting it off if certain conditions are met, or limits exceeded in our cars. I think if we can keep working at this, we may atleast have a central location for anything anyone would need to know before attempting this.

I'm not familiar with HPTuners but if you could reprogram a "useless" output from the PCM like the egr control or some other unused . . .. at thing you could have it "on" only at certain rpm'* and engine conditions.

Thats how we did it on the DSM'*, our engine tuning software (DSMLink) was very flexiable.

If there is no way to do that in HPTuners, then your stuck with a RPM windows switch and a WOT switch. If you have an aeroforce scan gauge you could tear it apart and tap a wire into the annunciator lights and have that switched power shut off the NO2 if you wanted to go really crazy.

I don't think that sounds to crazy at all. The scan gauge would be easy to take apart and solder a small wire onto. Another great idea IMO. Set up Annunciations for KR and whatever else which would trigger the light and shut down NOS, overriding an on switch which could be RPM or WOT based like you said.

I can't say too much other then avoid dry shot kits. A wet kit is much safer since you won't lean out on just nitrous and quickly learn how to melt pistons. As fortuning I'd imagine it being quite difficult on a PCM that is using OBDI.

And on a side note...it'* called Nitrous Oxide (or nitrous), not NOS (a nitrous kit company). People sound like they fell out of the fast and the furious when I hear that and it'* annoying.

Ya I cought myself in the second post and changed it lol.

Dry kits are for poor honda drivers, wet kits are for the big boys.

Oh. And Platinum plugs are a big no no.

Copper plugs are recommended and being a few steps colder will also help as a basis for nitrous tuning. And remove anything you may be using to advance timing as this will cause detonation which is bad.
