NOS question

[OT-OF-HERE!!]

I noticed that TS Perf. and PPE both sell diesel kits for NOS. Unfortunately they are $600 & $700 more than Jeg's Mac Daddy kit and I'm wondering why is there sooooooooo much $$$$$$$$$$$$$ difference? Couldn't the Jeg's kit be altered a bit and work for diesels?

The TS Powerfool comes with a "computer controlled comand center". That just sounds expensive. Probly shoots off at a certain amount of boost.

Nitrous on diesels is very simple, assuming you only add N20, no meth or propane or other such stuff. Since diesels run lean all the time, there is no risk like with a gasser, of melting pistons from adding too much, or too little. No computer is really needed.

Just watch your EGT, and nitrous actually lowers egt.

You can inject nitrous even at idle, or without any boost, to reduce smoke.

I would say you could switch nitrous on for the entire quarter mile or stoplight race, and only shut it off when you are done, it's only extra oxygen, and will not damage engine by itself.

It's possible to damage the turbo, and you can still melt down your engine from too much fuel. And I don't know if the same "safe" EGT still applies with nitrous, or you need to stay a little lower than with air!!!!!??????? There's only one way to find out, so be ready with the wallet.

Good to know... . Jegs sells a diesel Nitrous kit for $500 too. Just the basics are included, I guess thats all you need?



Betterthanstock, what does TS use the module for?

Nope,... you misread

Jegs has a NOS kit (two stage) for $700 but I didn't say it was a diesel kit,... that's what I want to know is what is the difference between their kit and the TS Perf and PPE which are both considerably higher,... it just doesn't seem that a switch or two or whatever the difference is could be that costly. Just looking for knowledge on this issue to get some direction.



Tks.

when tuning on a diesel for nos, you should back off of the timing some too.

i've never tuned or played with nitrous, but i've seen trucks that will get too much and put the flame out entirely they pop and buck and then most of the time die with very violent explosions, so its not very likely you can run it at idle unless its a VERY small ammount.

If you dont mind spending some time planning the system out you can assemble it your self. Dry systems are simple. you can spend as little as $300 if you find a used bottle and buy non ss braided lines.

I don't know what they do with theirs, but typically what's done is an "rpm window" and throttle position sensor/switch, and possibly boost/vacuum switch also.

Don't mix with propane or methanol. That really gets dangerous (run-away, backfires... ).

It will burn faster too, so you may want to back off on the timing boxes/downloaders.

I'd say start with a small jet, 100 shot tops.

These Zex kits look good too:

I'm no expert but just from reading on various boards that 3rd gen's dont really need NOS since our fueling and electronics is superior then lets say a 2nd gen. It's very easy to reach the max limit of cylinder pressure with fuel alone. Many guys that have a well thought out combo's that have high HP engines dont have the avaiable cylinder pressure that NO2 will take up.



Not too many 3rd gen's with NO2 and that may be why...



Correct me if im wrong... . which I may be.

 

[betterthanstock]

BigDan, what nitrous will do is burn off the excess fuel (black smoke), it will not add more power by itself, but yes, the extra burned fuel will produce extra power, so that means higher cylinder pressure and temperature.

Based on some videos I've seen here, they have plenty of black smoke that could be cleared up and produce a few more ponies.

Like I said above, I don't know what is a safe EGT with nitrous, so start small.

If you read the zex link above, it explains stuff quite well here:

By the way, NOS is a trademark of one nitrous company.

 

[OT-OF-HERE!!]

Maybe some Houston members could chime in here

Well for a couple years now RC Cox has been the icon for 3rd gen trucks. You won't find it (I beleive this is right, based on the last time I checked his sig) on his sig but I've been told he sprays NOS. I know Relentless has some really nice products but clearly RC has been running about 200hp more than like equipped 3rd gens so that's coming from somewhere. I would call that more than a few extra ponnies. The last I saw he was in the 850hp range. Now Chris' high pressure delivery system is stout, by all accounts, but the numbers don't add up. NOS may well be the answer to the rest of the equation. Thoughts?

The D-max in that link made 501hp with just a programmer, exhuast, and intake! WOW!

there are several guys around that running faster.

 

[OT-OF-HERE!!]

Interesting

there are several guys around that running faster.

So who would that be and what are they running (1/4 times)?

 

[Jetpilot]

Nitrous is not that easy guys..... To make big HP takes time, parts and tuning. The applications for gassers don't equal the same HP levels for our diesels. A good diesel kit will run LARGE PARTS, like lines, nozzels, solenoids, etc. Most trucks we setup use a 2 stage with a progressive controller. These trucks normally can make between 750-850 RWHP with a VP44 pump. With a good cp3 or p-pump more HP is possible.



There are dangers though. Nitrous increases cylinder pressure dramtically hence failures can and do occure. Headgaskets are one of the first issues to rear its head with nitrous use. I have seen numerous HG failures along with bent internal engine components not to mention destroyed exhaust systems.



As mentioned above nitrous can be injected at idle but the amount is so small that it isn't really of benefit. If you want to make power with nitrous go big. Don't look for egt reduction as this is not the reason the run nitrous. To see an egt reduction you will need to feed very large amounts of nitrous into the system. Nitrous does make power, NO turbo is going to produce what a bottle of nitrous can. But then again you don't have to keep refilling a turbo.

here is one for ya www.nadp.ca is where you should look.

Not too much, but i'm learning
