200hp yes, 210-230 maybe, that said, I have a 50 shot, don't let anyone tell you nitrous is a waste of time or money, it works, I use it when I need it, people's jaws drop when they see a TDI blast by them with anger and fury, lol, it safe if not over done, 50 shot here, try it, you will like it, I PROMISE...
that said never dynod my car with it but in the 250hp for a tdi is fast...and reduced EGT when spraying...

Are you just running a dry shot?

Hi by how much is it lowering egt's.

Hey jsf350 ask some of the same questions you have and got beat down on this site to. I also have a hot 03 cr dodge running in the 10s at 127. Do all my own work as well. Will let you know what I have learned so far on my 2013 golf. Have full exhausts, Malone stage 2 tune, with the dsg tune for the trans. It is a blast to drive avg between 45 and 47 miles to gallon. Ran to Chicago this weekend Looking to get about 655 miles out of this tank should put me at almost 50mpg on this tank. Really like the Malone tune so far. Have a water/meth kit waiting to go in. For cooling and mpg boost. Also going to add an s3 intercooler to help cool things down some but don't have that yet. After that also looking at building a twin set up but going to be tight in their. Have twins on both my dodge trucks. So cant be that big of a deal to map a set down for motor size. Their was a guy up north from me with an older vw hitting 500 hp put believe he bent some rods and backed it down some after that. If these little cr motors are anything like the bigger ones their is some power to be had with great mileage to boot.
to boot.

I have not seen it in this car yet, but still messing with it, in other Diesel trucks I have had it help buy only when on after off the gas temp will go back up, I need to get to the strip and do some runs, have a scangauge2 now to get more info on hand...

Basically, more full, higher EGT's, if you just spray without adding fuel, yes it can lower EGT's...
True! but just spraying with out having the extra fuel needed to support it to be able to add more power will definitely lower egt's but it will also lower the efficiency of the engine and will rob power.
A couple of guys who used to use it had it mapped into a different tune that they could switch in and out of when needed , which work out pretty well.

Very true, I have a tuner that is going to map a few possibilities to see where we can take it...need to work with jet sizes to get a nice spray, I really don't use it that much, I had a system left over so decided to play with it...

thanks guys... yes a new turbo or a compound setup will provide every day driving power.. but i have a spare nitrous kit and it wil be fun to play with...
i will email mark about adding more fuel for a nitrous tune

i think a 40 shot is still to big esp to start with.... but i could be wrong

You're limited by fuel, all the nitrous in the world isn't going to help you blow by anyone.200hp yes, 210-230 maybe, that said, I have a 50 shot, don't let anyone tell you nitrous is a waste of time or money, it works, I use it when I need it, people's jaws drop when they see a TDI blast by them with anger and fury, lol, it safe if not over done, 50 shot here, try it, you will like it, I PROMISE...

Plenty of fuel in the CR engine to burn, and with mapping I have done all sorts of different thing to this ECU...

This engine is limited because of a weak turbo, there are bigger a badder turbos for these cars, it has enough fuel to spool and burn...

Our CRs are currently limited by fuel. Look at "storx" and his build. He is trying to fit a CP4.2 because of FUEL limitation. Nitrous is not a fuel and no amount of it will help an under-fueled situation.
BTW there is no "shot" of nitrous for these engines. This talk of 40, 50 shot etc. is silly. If you mean "40 shot" to mean 40hp power increase, you won't get that exact power gain with these engines because of tune variations, build differences, etc. Marketing on any of the diesel-specific kits are geared toward trucks, not cars....with the exception being the UK's Wizards of NOS.
Nitrous is trial and error with these cars. Just because you are running a .040" nozzle doesn't mean you get 40hp extra.
To quote Holley (NOS):
"Nitrous combinations are derived based upon 950 psi (85° F) nitrous bottle pressure. Using the listed jetting and nitrous pressure, levels should yield safe and reliable power increase.
This system is designed to aid in burning excess diesel fuel in the engine only. If the engine is burning clean or lean adding nitrous will not help the performance of a diesel engine. It is recommended to have fuel system and or computer upgrades with jets larger than .030. If the vehicle appears to lose power then you will need to step down on the nitrous jet."
The following is a list of approximate gains in a TRUCK for different size nozzles:
Nitrous Jetting / Approximate Power Increase (BHP)
30 30
35 45
40 70
45 90
51 115
55 130
YMMV

You would be better off getting bigger holes in the injectors so the injection window will drop along with EGTs and smoke. Not sure how the new CRs are like with that but on the older ones, fuel is definitely a limiting factor.

only way you make power with nitrous on a diesel is if you have unburnt fuel.
even on stock diesel trucks you can pick up 10 hp+ with nitrous...fyi

Nitrous on a stock Cummins/Powerstroke/Duramax is useless. Why would you waste that $300 on a nitrous setup when you could get something like a PPE economy tuner for the same price and make how much more power?
As for the CRs there's a reason why guys are looking at upgraded pumps... Not enough fuel.

Most of you on here have no idea, I have a 50 shot it works on our cars, we are not limited by fuel we are limited by a little turbo, I will race anyone with a CR engine with my mods and I guarantee my 50 shot will put me ahead, I'm using it, I know...

You need more fuel for higher horsepower applications, with our 140hp and some mods there is still plenty of fuel to burn, it's when you get into bigger turbo's or compound turbo's on these cars where it will be a problem, but a 50 shot, give me a break, you don't need more fuel, I spray everyday...

You don't need more fuel because you aren't spraying much to start with
Increase N2O nozzle + solenoid orifice diameters and/or upsize your turbo and you will see your HPFP needs some upgrading to a CP3 or CP4.2..
A little bit is often only enough for a short while

thanks. that Avatar was originally Jeff's (rocketchip). he changed his some years back so i took it since i run NX stuff..Sweet Avatar, I like the little SPRAY GUY NX...
been spraying N2O since almost 10 yrs. now
there is a reason the fastest TDIs use it. StingRayRT (ProfitTuning), the Finnish guys (yucca, hatemi), Gulu (DynoSoft), RyanP....all know how well it works

I say a 50 shot, but like you said earlier, really don't know how much it is with the CR, lol...thanks. that Avatar was originally Jeff's (rocketchip). he changed his some years back so i took it since i run NX stuff..

Sounds like you should be driving a hOnduh and not a VW.

yes more ways to pick up MORE power then adding a nitrous system on a stock truck...
my point was you can pick up power on a stock diesel with nitrous. i know there is power to be had on a tuned tdi.. not saying a **** ton.. but there is some unburnt fuel waiting to be turned in hp/tq
i agree with vwracer... over 3200 rpm there is a hase/smoke from my car.. the turbo cant keep up/push enough air

Any updates on the NO2 idea? Let's see a dyno sheet.
