Hey man,
Did you install your nitrous kit? What "safety" precations are you talking about you did when you insatlled it. What's the biggest shot I can go with destroying my engine and for how long? I have pretty much the same mods as you so you can go from there. If something goes, what would it be? Intake? Block?
Thanks man, Mike

Well, you know about the Fuel pressure switch, and the WOT switch, then then there should be a a window of some kind. I personally like the MSD window switch (3k-5800rpm for me), colder plugs (NGK TR6).
I'm also using the MSD DIS6 which is a really trick ignition. You can run a lead from the N20 solonoid to the box and you can dial in spark retard when spraying (2deg for me). I kept the injectors at 24#'s, but the stock injectors are sorta iffy, so I put in SVO 24# (whats with the Ford injectors? ). I also have a MSD 155lph inline fuel pump, but I'm not sure if I will install it (good insurance, but I havent found a place I like for it yet).

The advice I've got from some reputable (to me anyway) mechanics are to stay away from Tbody plates because they dont distribute the N20 effectively, and if its a wet system they will lean out the back cylinders (bad).

I have a wet kit, and the trouble with that is fuel puddling in our intake which was only meant to flow air. Seems you are most vulnerable between shifts, but the window switch is the precaution against that. The wet kit doesnt strain the injectors or the pump, and you can run a bigger shot with more piece of mind.

The safe zone on squeeze is debatable, but most people agree that 100hp or less will be fine on a 350ci, just keep a eye on the plugs and the air/fuel ratio. Also, alot of people arent running a purge, so there is a delay before the intial hit (N20 comes on all at once, no waiting around for boost to build) and that allows them to get out of the hole with traction and may add life to the glass rear that blesses the Fbody.

Thats pretty much it that I can think of
Put it in, and let it rip

Are the rear ends really that weak? That's all I keep hearing about. Not just here but everywhere. I guess they are weak then:)

Good info, thanks. I am thinking about scooping up that NX kit they got a group purchase on at Tbyrne. Comes with the MSD module you are talking about. Thanks again man, Mike

Stealth Performance is doing a GP on TNT nitrous kits. YOu will get better numbers from a TNT kit.... I think that would be what I would get.....

Really?

LOL.... You a funny man...

Being really serious here. Explain why you'll see better numbers. Also where exactly does that hook up, looks like it hooks up behind the MAF sensor. On a wet kit if it hooks up there, you are on borrowed time.

I can not talk about the LT1, but from the LS1 standpoint, yes it does hook up behing the MAF, as do all wet kits that are not direct port. You cannot use a wet kit before the MAF. The numbers are higher due to 2 things, 1. they are rated at rear wheel HP and 2. The have a patented spray nozzle that just makes more power.

I surf around all of the bigger forums. If you take a look around them you will see that the bigger #'s are coming from TNT kits. I am not saying you can't get good #'s off of a NX kit, but TNT is showing a better rate of good #'s...

As far as being on borrowed time how can you say that? If you are using all of the safety items(Window Switch, Purge, WOT switch and a bottle heater), how can you say there would be a problem? If you are set up right and do not go beyond the limits of the kit(flukes or accidents aside), the fuel will be properly mixed and atomized with the N2O prior to entering the Intake Manifold..... Let me know what you think..........

location, location, location.

If you put a that nozzle (behind the maf) then you are shooting a fuel/N20 mix thru 12" of rubber tubing that has a 90deg bend, then thru the T-body into a dry intake.

Basically you are just increasing the chance of fuel puddles that "will" eventually blow. Now, if it is a Tbody plate, then I would change my tune.

Dont get me wrong, I've looked at the TNT kit before and even emailed about the conversion kit to change from NX to TNT delivery. They wanted $400 just for the Nozzle hook-ups.

Oh, I see where we are getting the conflict... The MAF on the LT1 is in the intake elbow.... That is true, that is a long way to travel.... On the LS1 it is right before the TB......

So on the LT1 TNT might not be better as far as their LT1 kit is concerned, but they do make a universal wet kit that haz a patented fan nozzle that would go right before the TB....... That is what I would get then, but then again TNT has tested their kits and are happy with the results that they have achieved........$.02
