My cousin and I put the one of the last PPE nitrous kits in existence on his 07 LBZ EC/SB last weekend. The install was fairly easy, besides Dan not having instructions to send.: He had Nick from Duramaxtuner make him a NOS tune and a high rev TCM tune to go with the Merchant trans. He put a .070 jet in and went for some testing. That wasnt enough, so the .099 went in. http://www.youtube.com/watch?v=oqbHDkYWgsQ
The first blast was the best, as it was hard to keep bottle pressure at 1000 when you hit the button 4 or 5 times in a row. So the first bottle was a waste, but fun. He needs a bigger/better bottle heater, so if anyone has any suggestions on a good one, please post them. The tuning is great. I only saw 14-1500º when the NOS was coming out correctly.
He took it to the dyno yesterday to get some numbers. Here's what happened.
This a stock motor, stock turbo truck.
The truck made 504 508 510 with no gas. Bottle pressure was 1050 for that run. As pressure dropped, so did the hp.
Thanks to Nick for hookin us up with all of our tuning and to Eric for whatever you did to that trans.
Now thats some cool sh*t! We need more real-world info like this!! I've got an NX kit sitting in the garage waiting to go on the truck as soon as I can get an upgraded tranny....
It's still running. Heres a pass at the track. The bottle pressure was low and he only got 2 good runs. The first was a 12.33 @ 114. The second was 12.44(i think)@109. And if it melts, off to Erics!!! We've been busy the last few weeks and havent made it back. He has a 50# bottle to fill. . I'm pretty sure it has high 11's in it. http://www.youtube.com/watch?v=DIr3v_LxC-Y

The pressure will be better with two smaller bottles in parallel than one big bottle.
Nitrous can only boil at a certain rate. The large bottle will have better pressure on the first hit, but as the bottle empties out, pressure will drop faster because of the speed that nitrous boils.
Nitrous should only go in to the system from the bottle in a liquid state, and change states to a gas as it leaves the nozzle. The bottle pressure is important maintaining flow. As Bottle pressure drops so dose flow.
Now the correct way of introducing nitrous in to a diesel. There are two locations, and both have very distant rules and applications.
Nitrous is a cryogenic gas , as such when it leaves the entry point it boils at -126 f , when it boils in the intake track it absorbs heat. This drop in intake temperature is the limiting factor to using nitrous in a diesel engine. When the temperature becomes too low the ignition is delayed or even nonexistent. This is why nitrous must be introduced as the engine can take it with out.
First ...... pre intercooler this is the most forgiving , but gives up the intercooling effect of nitrous , this is the best place to ramp in nitrous to spool. I Have data logged temps on both sides of the intercooler, and the temp coming out is not effected but a few degrees by nitrous on the hot side. Second post intercooler, this makes the most power, but is not as forgiving. the best place is as close to the exit of the intercooler as possible, to allow the nitrous to mix and homogenize Boost reference progressive I laid out the first boost reference controller about 6 years ago, and this is the basis of the systems currently in use. The latest generation of this, is currently on the flow bench at Nitrous Outlet. Nitrous Outlet is the only company that has a true flow bench that incorporates extensive data logging I use nitrous to get on top of large and efficient chargers , and the nitrous in this application make extreme gains on the lower sides of the curves. I also use nitrous to help launch at a lower boost level, and allow the power to come on at the truck moves down track, this puts less stress on the drive train. Example leaving at 10 to 15 lbs. of boost instead of extreme boost levels that are hard on drive trains
www.nanonitrous.com I helped develpoe this back 2 years ago, and will not run nitrous with out it. i gained 1.5 tenths and 3mph just by bolting it on.
No offense but we were using "push" system's in the early 90's, just not commercially available systems. I ran dual "nitrous" bottles, one bottle was regulated nitrogen.
I have used NANO and its works, Nitrous Outlet uses NANO, and their push in to the diesel world, is going to take diesel nitrous to the next level. I have chosen Nitrous outlet and their American made stainless steel solenoid’s to build not the next generation, but the best possible system for our diesels I can’t tell you how many time I have had problems with foreign made cheap aluminum solenoids, they either hang shut , or hang open, this problem is solved with a higher quality solenoid’s.
I have some cut away of the cheap aluminum solenoid's , I'll post them up soon
