Who Wants To Talk About Nitrous ?

Like the title says.........

I started this Nitrous conversation as a back n forth information thread, maybe it will help out a few guys.

Now that's a 100 page book all by itself.

I would prefer actual Nitrous based questions from those who are considering installing a system or for the guys that already have a system in operation. Also I'm a BIG believer in the concept "Less Is More" when talking about Nitrous.

I'll start by saying that the Target AFR number for a single wet nozzle system should be about ~11.5 to ~12.0 AFR. The Target AFR for a D/P system can be raised slightly to about ~12.5 to ~12.99 AFR.

Looks very nice, I'm a big proponent of the stand alone race gas fuel cell. Hopefully you're running something like VP N02 to take real advantage of what that gives you in knock suppression & the ability to run more advanced timing.

What fuel pressure do you run with yours ? Hopefully it's around ~3.5 BAR, as opposed to a low pressure system.

Iím running conservative. 32 jet for nitrous and 17 for fuel which doesnít require ignition retarding. This is supposed to give me extra 50 hp at WOT. Iím using 100 RON fuel. Iím still experimenting and I donít have any real values.

Though that's Zex's "Safe" recommendation for a 55 HP shot, I'd still REALLY encourage you to run a wideband AFR gauge if you're not currently. As aready stated, your target AFR is roughly 11.5 to 12.0 at WOT.

What exact plugs are you running ? Have you started to read up on Plug Reading ? The ability to read the spark plugs becomes very important as the Nitrous levels are increased.

It's really not. But what specifically do you mean ?

In a way it's no different than you & your extensive knowledge on Dynos, most guys might be intimidated by the idea of dynoing & probably don't understand how to read the results.

Plugs on DI are different than plugs on N52 and there isnít much choice.

I would throw out those plugs Quick, 3 & 4 prong OE plugs have a BAD history of melting & destroying engines in Nitrous applications.....

I was Not able to determine if this is the correct plug for your motor, but if it is, this is what I'd tell you to run.

NGK LFR6AIX-11, Stock Heat Range

NGK LFR7AIX-11, One Step Colder


EDIT 1: Is this your plug, NGK ZKBR7A-HTU ??

EDIT 2: After more digging on the NGK ZKBR7A-HTU spark plug, realizing that this is virtually your only choice, I'd cut 2 of the 3 prongs off of each plug leaving you with a 1 prong plug.

Nitruos

Hi,saw you install,how is that working with the 3stage intake? Do you feel it's optimal with the disa valves? I'm hearing a n54 intake may work a lot better and a better distrubution of nos and fuel. I'm going to tap in tps sensor and try to program it after the first stage is open. What are your thoughts and observation? Thank you.

I have N54 manifold ready to install with software from Bob. Iím putting back the nitro stuff which I took off over the winter. Hopefully I will have the manifold with nitro installed in a few days and I will take it to dyno.

Ya,I heard there is a tune he' s putting together with that setup. He said it would it would run great with the nod cause of the rpm capabilities of both. What worries me is the loss of low end torque. I know this tune makes it up,but what exactly does this tune supposento due?,and is it really nessary. Is the PC hoses eliminated? What gives? What are you putting down now with the now? Thank you

Unfortunately I don’t have dyno of my setup with 3 stage manifold. Last fall when I had the car on dyno I had a gas leak and we had to stop it before I got any figures. I don’t have any dyno locally and I didn’t manage to get back after I fixed the leak.

Well,that may be the safer way to go is with an open plenum intake,that would suck if you nitrous is full bore and you disa valve gets in the way. It look is like nitrous is one of the only way to bump this motor up in power,with the right tune and hardware,this could be a good way to go. Even the supercharger would be out of the question,cost per hp.
