Question about nitrous kit.

Venom VCN 1000 Computerized Nitrous Kits from HorsepowerFreaks

What do you guys think about this kit? I just want a 50-75 shot to be safe on the motor. Its got Edelbrock HCI, long tubes, full exhaust, 24lb injectors, 80mm MAF, diablosport tune. Just looking for the little extra without going a long way.

 

[yukisho]

You should be fine. I know the stock engine can handle at least 75 shot with ease.

Nitrous can be enjoyed quite a bit on our little 302's... My mechanic, a local real street guy, in the past has slapped 200 shots on stock block 5.0's. 150 is known around here as the biggest 'safe' shot you can run, but like anything, it's all in the tune. There's another guy locally who hooks up nitrous kits to stock block 5.0's, and pulls the pill out of them. He runs insane times... Until the motor says bye bye.

The foxbodies, (minus the 93's I think) had forged aluminum pistons in the factory shortblock. The 94-95 5.0 has hypereutectic alloy aluminum pistons which are a bit more brittle than their forged counterparts. The older 5.0 shortblocks could take some impressive amounts of nitrous through them. I don't really suggest going over a 125 shot on hypers though. They don't take too lightly to detonation and are more likely to fail. This being said you should be perfectly fine on a 75 shot though.

2 main things to pay close attention to with N2O.

1) Avoid detonation. Make sure you don't run too much timing or a fuel too low in octane.

2) Make sure you have enough fuel and don't let it get too lean.

+1, I forgot that some of the foxes had the forged pistons. I plan on running a 75 shot for my GTS, but plan on backing off timing back to 10*, and making sure I'm dyno tuned flawlessly.

If you are going to get dyno tuned, then set the initial timing to what they tell you. (I would imagine 10* as you said) Other than that, you could have them burn you a NA chip and one for nitrous on a flip chip. The nitrous tune would have a slightly less aggressive timing table but would run amazing on the bottle, and the NA would be more aggressive than you would want to run on bottle but would run great on motor. That way you still have the grunt when you are running around on the road outside the track.

The hypers in the 93' and up stangs are actually stronger than the forged pistons of the older stangs. You can run 100 shot with out worrying. However, I wouldn't try a new kit like that. Stick to something tried and true like an NX kit, or the old NOS dry kit.

Yeah actually I have heard that the forged pistons arent as strong as people seem to think. Besides the fact that the block usually gives out before the pistons anyways... I was just curious if a 75 dry shot would be ok, lol.

 

[302GTS]

LethalInjection, I planned on having the dual tune kinda thing going on. Our local tuner told me he'd only charge me an extra $25 I think it was to burn a nitrous tune for me.

Are wet shots better than dry for a nearly stock application? Looking for safety/reliability, not so much ease of install or anything. I'm looking at a 75 shot pretty soon...

 

[revhead347]

The safest most reliable is the old NOS dry kit. Wet shots aren't too bad, but they are a little more on the risky side.

Cool, thanks. I'm saving my cash now and plan on doing all my mods at one time. Gears, tires, suspension, spray, dyno tune. My girlfriend's gonna have a realll boring Christmas this year.

 

[revhead347]

I picked up my dry nitrous kit used for $150. You can usually find a really good deal on one if you hunt around. I have made a lot of modifications to it, most notably changing the solenoids over to NX brand because they are much more reliable.

I don't want to hijack this thread, so expect a PM from me with a couple questions. Thanks Kurt!

I ran a 100 shot for awhile on my hypers before I put my combo together. Saw no sign of stress from that on engine teardown. I only say that because I found a 50 shot to be quite underwhelming. I'd buy something that will do a little more. You don't have to use it, but it will be there. I don't know a lot about the Venom kit so I am not slamming it, but I wanted something a little more simple. Couple relays, WOT switch and a low fuel pressure cutoff switch is all the electronics I wanted for now. I like my NX wet shot a lot. Other brands are also good. You will find them jetted conservatively. You should research the quality of the components in any case. Nitrous Express is one of the brand kits that comes with high quality stuff. Nitrous replacement parts are expensive so you want something known to be reliable or it will likely 50 dollar you to death later.

I've bought some offbrand ebay nitrous accessories since then. What a bunch of trash. Leaking fittings, relays that work for 30 seconds etc.

I ran a wet 125 kit on my stock longblock. The only thing I would 100% say is a MUST HAVE. GET A WINDOW SWITCH.

Hypers can take some abuse and a good size shot if your on the safe side and dont get greedy. People get overly confident with the forged pistons...they will melt too as they are not indestructible if you get greedy.

13.1 @107 on 100% stock longblock and street tires...makes for a nice sleeper since our body style is not known for the times they put down.

Oh yeah, I'm not really doggin the FACTORY hypers that much, just making sure everyone was aware that these really ARE different pistons that you hear ppl spraying 200+ on in the foxes. LOL I personally have had a 125hp wet kit on mine several years ago with no problems still yet today. However, they still don't take as well to detonation as the older ones, so no matter what you spray, just don't let it go to pingin. This is true of ANY nitrous setup regardless of piston though of course. Our guts are just a little less forgiving than the older foxes. A guy I used to run with at a 1/8 mile track had 2 foxes. One in the low 6's on a former turbo longblock converted to carb and alot of spray, (Street legal, but nothing on it stock. lol) and his daily driver that went from 8.40's to 7.19 on the bottle with stock shortblock, stock heads, and aftermarket intake, cam, exhaust, gears, and boltons.

For a 75 shot a dry application would be the safest since you are getting it dyno tuned anyway. Wet kits are fine and allow you to input the amount of fuel you need with it, but it's best to inject that fuel below the upper plenum where there is a more direct path. Our upper intakes aren't made to flow liquid through them and the bends, nooks, and crannies can lead to fuel puddling. This is not really THAT big of a deal unless you get a backfire for some reason while the fuel is still there. Then it pops inside the upper. I have seen it do some strange things when this happens up to lifting the upper a bit, due to either gasket failure or pulling the bolts\studs. It's not really the norm though, but can happen.
