It should also be noted that all forms of FI, whether it is turbo, supercharger, or nitrous, also have limiting factors that prevent forcing too much air into the motor.

Boost controllers, wastegates, and injector jets are all designed to keep from forcing the compression ratio past the desired limits set by the tuner.

I think looking at Volumetric Efficiency may be in order....

A 50cc chamber almost never get's all 50cc NA - but can get even more with good intake and exhaust tuning.... a set volume of PPO2 will provide a set increase over the stock power curve regardless of RPM. If the mass of nitrous doesn't change at higher RPM; then it will equate to less power - however I am not sure that the nitrous controllers only release a set mass - since the engine air velocity will create a higher pressure gradient and ingest more mixed gas. How the module works would be a good question for Ray.

Dang Charles R. Hill, We sure are dissappointed in you. You should be so ashamed of yourself. How dare you call yourself a vendor?

Shnifty

If you say so....

i dont know your train of thought, but...

i just bought his flywheel and a counterweight from him. and i've bought spark plugs from him in the past.

seems like a vendor to me. and a good one too.

realize that vendor =! researcher

the fact that he does that too is just icing on the cake man.

Shnifty

I'm definately being sarcastic. I've dealt with and read all about Ray and BHR. I very much appreciate everything BHR.

Well isn't this thread getting interesting.

Shnifty

How about this: To get this thread back on track, I've never used nitrous before but I"m thinking about using at least a 75 shot and a progressive controller. Any advice before I blow up my car?

Dont

A more realistic answer.... i do not believe that anyone is succesfully pulling off a 75 shot. i have heard of one or two people getting it to work for awhile, but they are going through intakes like mad. Then again noone to my knowledge is using a progressiv controller on thier setup. Just know your going into uncharted territory and anythign can happen.

agreed....

well i said f it and dropped in 65 shot jets no problems yet don't feel much of a differences but all well.............

I like the idea of Youtube'ing it. I'd like to watch what happens.

I am. Mine works fine. It does require a special tune with the Accessport. And that is still an ongoing work in itself. But it just keeps getting better all the time.

As for the intake manifolds blowing up,,, well I am the cause of that. The nitrous/fuel does not like low rpm high load. Especially with the AT.
Low intake manifold vacuum is not good.
Unless you can maintain the rpms above 4500, say from a start, your going to have issues. So I do not recommend a dead stop nitrous shot. Though I have done it before. But it's about a 50/50 result. Neck snapping acceleration or boom goes the manifold. You make the call.

ok 65 shot no problems and i hit it hard maybe im lucky but only time will tell

long island ny tuner said i can get 75 with no problem going to see him soon updates will come

Might I suggest you stop using a liquid fuel in a manifold not designed to flow a liquid and switch to propane instead....

http://www.ls1tech.com/forums/nitrou...formation.html


vipers and vettes have been having a lot of success in combating fuel puddling/intake backfires by getting away from using gasoline.


it seems like the big issue is tuning and the intircate UIM causing fuel puddling. Besides the benfit of pressurized propane not taxing the fuel pump and being roughly 105 octane, its a gas so it will flow through the UIM the same way that air will.


Read through the thread I linked. There is some information on what diameter orifices to use with propane and a few shops that are working with it already.


Just a thought.

The issue I see is regulating the fuel flow with the propane. The nice thing about the zex controller is it's ability to vary fuel flow based on bottle pressure. Not a serious hurdle by any means.

For the most part, fuel puddling is only (IMO) a serious problem in lower RPM situations. Keeping the nitrous off until around 4,000 or 4,500 RPM's would be fine.

It's worth a look into.

Now you want me to carry around a Propane tank in my trunk.
I'll just use it above the 4000 rpm range.

Flashwing

There is something to consider about the safety issues of carrying an explosive gas in a canister. If a nitrous tank is compromised it will simply vent to atmosphere and be harmless.

I wouldn't want to get rear ended and die after my propane tank exploded.

Far fetched? Probably, but are you willing to bet your life on it?

I had a motorhome that you could switch over to the onboard propane tank, instead of using gasoline. I see this more on pickup trucks rather than cars. I see it as more of a lack of space issue along with a safety issue. You wouldn't want to carry a tank anywhere in the enclosed area of the car where a gas leak can accumulate.
If it was possible, it would be great. Propane can be cheaper than gasoline. Plus there is the cooling effect as the compressed gas expands.

Hoss

I thought the propane deal was a power adder that diesel's used. I could be mistaken on that, but I have been under the assumption that diesel motors can take the propane and use it to add power much like how a gasoline engine uses the nitrous.

Hoss

Both Bully Dog and Banks make rediculous power out of diesel motors...
