Default Free Nitrous...

Ok, quick background.

My 68 coupe has a 302 V8 with the following modifications

650cfm Holley carb with electric choke
Edelbrock RPM Performer maniford
MSD ignition and MSG-6al
March Performance underdrive pulleys
High flow water pump
24" 3 row aluminium radiator with dual electric fans
Uprated cam from PO, no idea on spec/brand

The gearbox recently had a higher stall torque converter installed 2800rpm.

A friend of mine used to have a Nitrous kit installed on his Honda which he has sold. The nitrous kit is sitting in his garage taking up space and he offered it to me today. From what I understand the setup is for a 100 shot dry.


1) Someone offers you a nitrous kit for free, what would you do?

2) Is a wet system safer than a dry nitrous set up?

3) Can I buy smaller jets and make it a 50 shot to limit the power?

I haven't changed my pistons to forged, do you think its a bad move taking this upgrade?

I use to know a lot about NOS but let me see if I can answer your questions.

1. Take it and sell it.
2. Wet suppose to be safer
3. I believe you can buy smaller jets and make it a 50 which is a whole lot safer.

50 shots you're pretty much safe. If you wanted to shoot more, you'd have to lower your compression with stronger pistons. I'm sure someone here has NOS. This is knowledge from back in the days I raced hondas with NOS.

I put nitrous on a Yamaha moped years ago. 2 stroke engines are pretty indestructible.

To answer the op's question. Dry nitrous systems are designed for electronic fuel injected cars where you can inject more gasoline by telling the computer to shoot more gas in the engine. Wet systems have a separate fuel injection system to enrichen the fuel mixture. You have to use a wet system on with a carburetored engine. If the system is "jetable", then you should be able to put small jets in it to run a lower horsepower nitrous system. You must use forged pistons with nitrous. Properly run, nitrous is fine. Go lean and kiss your engine goodbye.

That kit won't work on your carburetor. There's no such thing as a dry shot on a carburetor, because on a dry shot, the injectors work harder to compensate for the oxidizing effect of the nitrous. Any time you add oxygen (nitrous), you have to add fuel, and the injectors do it automatically.

So carburetors use a plate kit, which sprays nitrous and fuel, so the kit, which I assume is a nozzle kit, simply won't even hook up to your carb'd engine.

On the comment of just jetting it down to a 50 shot, if the kit isn't designed to go that low, it's very unsafe to jet it that low. Kits are designed for a specific range (like mine is 100-300), so the spray bar and solenoids flow X pph nitrous/fuel, and when you try to choke it down too low, it can cause very uneven dispursement among the cylinders.

You can spray on cast pistons, especially a small shot like you're talking. But it's all relative to the tuneup. Nitrous does not hurt an engine, detonation hurts an engine, and nitrous will magnify that. You could spray a lot of nitrous on a cast piston, if the tuneup is good and it doesn't detonate. Get the tuneup off a bit, and get detonation, the ring lands lift, the piston melts, and its ugly. Forged pistons just provide some room for error.

Finally I holeshot you at something! lol

You're right, you can shoot nitrous on cast pistons. Just don't expect them to live long with it. And you're right about detonation. Nitrous will just magnify detonation. And even if you have forged piston, you'll pound your crank bearings.

To the OP, you can't just bolt a nitrous setup on your engine and go. There are so many things you need to do. Beyond making sure your engine is setup for it. You have to have an adequate fuel supply. Stock lines and pumps won't work. You must use larger lines. When I ran nitrous I had 1/2" line from the tank to the carb and nitrous fuel solenoid. I ran a racing electric fuel pump and pressure regulator. And there's more steps to take.

Personally, I think nitrous is a waste on the street. I ran a 150 shot in my avatar 70 Mustang on a mild 351C and it would just blow the tires away on the street, even while driving along. I had my suspension setup for drag racing and I ran a special soft street tires out back. I could only see any real benefit of it at the track on drag slicks. It did knock 1 second of my elapsed time and I gained somewhere around 10 mph in the 1/4 mile (It's been over 20 years since I raced that car and I lost the timeslips).

Dang! That was a big edit...lol

I have never even attempted to spray mine on the street, and I won't. I can't even remotely get it to attempt to hook up on the street, just on motor. Nitrous would be useless.

I did go from an 11.18@122 on motor, to a 9.92@134 with about 160 HP worth of nitrous. It went 10.22@130 with less than a 100 shot. Nitrous is gooooooooood lol

I used cast pistons with 100 shot nitrious for over ten years on a 289. never had a issue. Used that same motor for two years after with 10 lbs of boost, before upgradeing to a dart block. This was a stock bottem end, with a cam/head/ intake upgrade. It can be done.

Since i"d consider buying nitrous, I'd definitely take it for free.

And the perk of the 5.0 EFI, is forged pistons, and fuel compensation. booyah

A friend of mine sprayed a 250 shot on a stock 5.0 all year this year, with no issues. 180,000 mile shortblock, Vic jr intake, small comp cams hyd roller, GT40 heads, Holley 750 DP, with a stock C4 with a stock converter. Went 14.60s on motor, and 10.90s on the spray. I bet it made 100 passes this year, and finally hurt the trans.
