NOS Diesel Nitrous Kit

[Archive]

Just installed a NOS Nitrous kit for Diesel only application. #ad
All you BOMBers out there really want to step up to the plate, go for it! The kit is affordable, and very easy to install... ... the only requirements are that you must be running an excess of fuel to the engine (Definition-the truck smokes). It has five jets which can set the power anywhere from 50-300 hp. #ad

Won't hurt the engine or the turbo. If you don't have enough fuel at the time of hitting the button, it's as if nothing happened. Nitrous is verrrrrrrrry cold too, so it lowers the temperature of the intake charge. Lots of bang for the buck. More kick than the propane system I test drove.

I've only seen 50 hp with Nos while dynotesting. I run a mid range to large orifice. Adam's results with Nos are similiar. This is at peak horsepower.

Who is getting 300 horsepower with Nos?

You asked for it, you got it! I've got over 1000 hp from N2O alone!

Now the dissapointment: That's with a 632cid Chevrolet on Alcohol. #ad

The cummins / dodge is to tow it!

... are you running dual foggers ??? or plates and foggers... NOS ya gotta love it... JB

I personally haven't tried anything better than the 75hp jet. The truck still smokes heavily while on the juice, so I can move up to a bigger jet yet. #ad

I have gone past the point were nos was injecting to much, it just dies. The thing is you really cant have to much air, diesels have as much as they can "use" all the time right. Well, no, if you smoke your not burning it all. I have found that around a 50hp jet wont kill your motor wile reved to the max, thats what it use. HVAC has found the same kind of deal, he has his on a micro switch meaning its turned on at full throttle by switch. He started with the "300hp" jet and worked down until it worked properly. The facts are its usually only worth 50 and plus a little but it comes on instantly. If you smoked a little, you wont, you'll burn it all now. Not bad on your motor, it just works now. No boost needed.

Yeah, people don't understand that a diesel runs on an open plenum. I think with the kit I have found the point where the engine will only burn so much fuel and no more. I tested the kit with the engine running at 2000 rpm and gave it a small shot and the rpms came down a hair each time the shot went in. It brought my quarter-mile mph up 4mph from my best ever and I only used it in top gear.

NOS does make a nitrous delay module that can set up a timed delivery curve of nitrous to your application. Pricey, but I'm gonna try it and waste a couple bottles tailoring it to my application and using even bigger jets.

cool Chris, let us know how this turns out.
Hey Chris, next time you race, try launching in 4x in 3rd. Bet you'll get into the low 13's easy. Show what your truck is capable of. I'm going to try weds.

Keep In Mind One thing perculiar to Nitros...

INSTANT TORQUE!

There is no build up like boost, or a fat part of the curve like a mean cam or tune. .

Just the introduction of Nitros (laced w/ Sulfur if using non-medical grade) and you supply the lopsided air fuel ratio, ie a fat/rich mixture. The byproducts of cumbustion of Nitrosoxide are H2O and Oxygen, water cools and more Oxygen burns the excess fuel. When it lights off, THE POWER IS ALL THERE, ALL AT ONCE!

Stuff can be hard on drivelines and clutches.

As for too much, too soon, and potential for carnage... my personal opinion is

RESPECT THE GENIE IN THE BLUE BOTTLE!

And before one engages in the "plus size" nitros jetting game, answer this question...

"HOW FAR ARE YOU WILLING TO PULL THE PIN OUT OF THAT GRENADE?"

Squeezed Intercooled Turbo Diesels... I LOVE IT!

Max,
There is no mixture or air to fuel ratio for a diesel.
AIR + FUEL = POWER.
The nitrous will only burn an excess of fuel which can't normally be burned by the engine. The engine won't lean out, pistons won't cook and things won't grenade. Low speed Diesels such as the Cummins B series make maximum torque just off idle. That's the biggest shock to the system. Either way, I'm still going to use a delay system with an adjustable nitrous curve to simulate more or less the effect of a turbo, rpm specific.

(longer than it needs to be)
No Air:Fuel Ratio?

Please see the following link
http://www.turbodyne.com/techrep1.html

Squeezing a diesel motor acheives the same result as other mods... trying to burn more fuel with a given displacement. Our ISB uses artifical aspiration via intercooled boost to cram more atomsphere into 5. 9 lites of displacement, more air to burn more fuel which makes more power.

The combustion of NitrosOxide releases oxygen and water as byproducts. The oxygen enhances the burn capabilites of the atmosphere in the cyclinder(s) and the water works to cool things a bit.

Day's end, you're burning more fuel, which increases cylinder pressure and elevates cylinder temps. The limits of the system could come from any of the following:

Fuel Systems Delivery Capabilities
Nitros Metering
Engineered limitations of the engines internals them selves
etc

The ISB will have a limit as to just how much Squeeze it will take before it will break... and YES, you can blow one up, send it super-critical or WORSE.

As for driveline shock, turbos, especially ours spool up. Take a look at a Cummins Torque Curve readout from a dyno, you just don't see a stocker run straight up. Take a look at a motor squeezed on a dyno, check out its torque curve... da... da... . da... WHAM!
Nitros, aka the poor man's super charger, is the closet thing to a true "ON/OFF" power adder, especially the simple single stage kits, doesn't matter how long you delay it, on is on. It is helpful to have revs up and already have the weight of said Ram in motion before delivering such a shock.

Draggers use multi-staged systems and progressive controllers as not to overwhelm traction when laying down large quantities of laugh'n gas, but such technology isn't typical of street applications.

I would add that while on the dyno in Escondido I had an awful detonation problem when I flipped the switch for the nitrous. I believe it was causing the propane to detonate prematurely. Much more of the noise I was hearing and I would have had to JB weld the piston perforations.

Also, I witnessed a head gasket failure while using nitrous on the dyno. This was a 12 valve motor, not mine.

Beware, these mods are not recommended for the masses or faint of heart.

Ps. Lov'n the DG111 HVAC, thx! I'll send ya a pic or two once I get through this module... back to the books.

Auto Wurks Diesel neither uses nor endorses propane injection. Of course it will combust prematurely. I posted a thread on that a while ago.
Mad Max, I have seen B series engines with pretty bad damage from things like oil problems, and turbos blowing up and shrapnel entering the cylinders, and an injection pump being stuck at 4000 rpm, and an injector hanging open and melting a piston. Have you ever pushed one of these engines to their limits?
Trust me, there is no stoichiometric ratio for diesel engines. Pick up a book called BOSCH Diesel Fuel Injection, look on p 12 "Since a considerable part of mixture formation takes place during combustion, local over-enrichment occurs and an increase of black smoke occurs even with moderate excess air. The air-fuel ratio which leads to smoke emissions bordering on the legal limit is a measure of how well the air is utilized. Prechamber engines operate at the smoke limit with an air excess of 10... 25%, while direct-injection engines have an air excess of 40... 50%. In the diesel engine. the fuel is injected directly into the highly-compressed, hot air with the result that it auto-ignites. The diesel engine is thus NOT BOUND TO IGNITION LIMITS like the spark-ignition engine. Consequently, considering that the air quantity in the combustion chamber remains constant, only the fuel quantity needs to be regulated. " If you enter an excess of air into the system greater than the amount which is required to burn the fuel which is to be injected, the rpms will actually lower themselves and there is no change in egt.
Consequently, I am using a nitrous controller... in order to get a more effective curve on the nitrous injection (to emulate the effect of having a second turbocharger which spools up). The controller is set to introduce a minute amount of nitrous to the system and gradually increase the curve. I used a #50 orifice initially in the system and anything bigger hampered the power. This is where I figured I'd spend the bucks and get the controller.
I checked out the web page and I see it does the testing on larger, truck engines like the Detroit road oiler. I see them talking about air to fuel ratios for exhaust smoke and egts. I don't care about the smoke level(that's what the valet switch is for), and my pyro gets to see 1300 most every day and the head has been off and the pistons are cherry. This is on a 550+ horsepower engine that revs to about 3500 rpm. Talk to My6eatsV8s and he'll tell you the same thing.

Chris-

I've managed to confine my "caranage" to gassers and drivelines more than anything else... the ETH has been spared thus far.

With respect to the potential for nitros to destroy an oil burner. If I'm not mistaken, Nitros is combustable in and of itself, so a leaky or stuck nitros solenoid can pose a serious problem in one doesn't employ other safe guards like an eletronic valve or shutting a manual valve off when not in use... etc. The cycling of the old grid heaters at start up post nitros leak could pose a problem as could preignition of the gas itself in the intake tract or in the exhaust tract IF SUCH MASSIVE QUANTITIES OF Nitros were present.

Sure these are rather extreme senarios, but my point is that a diesel engine will have a definitive capacity for nitros, an over concentration of nitros in the mix could spell disaster all by itself. Granted, most of the senarios would fall outside the "relevant range" so to speak, but to disregard "beyond" such ranges could prove catastrophic.

I can't tell you how many 5. 0 Mustangs I saw in my HighSchool and Undergrad days die because of the "if a lil nitros is good, a little more will be better" logic... granted ford's switch from forged to cast pistons further aggrivated the problem.

Max

Ps. Saw your rig in the TDR rag... nice! Thx for the tip about the Bosch book, I'll have to check it out.

Hey Nowel:
Should i run a NOS kit on my first gen? with the stock clutch?--hehe...

No, I wouldn't recommend nos for the 1st gen Greg. You take care of that truck and if anything go to a 12cm housing. Don't get caught up in this incesant persuit for higher
power.
