really looking forward to the next video, and maybe some time tickets...???

Also I don't know about dry shotting, I believe if you run a dry shot you should have the fueling to support that, unless you can tune your car I don't know if it is a good idea. This is all with limited knowledge, but from what I understand wet shot is safer as you run a less chance of going lean.

Both dry and wet shots add extra fuel. One would be stupid to force oxygen into your engine without pairing it up with the appropriate amount of fuel. Wet shots add the fuel by tapping directly off of the fuel feed, then supplying fuel through an additional solenoid and nozzle. A dry shot delivers the extra fuel through the factory fuel injectors. "Dry shot fuel" can be added via ecu programming or by bumping up the fuel pressure at the regulator (and maybe a few other ways).

But with a dry shot you need to add the fuel yourself with programming, right? (Something that you need to "do"). I mean I know nitrous allows you to burn more fuel efficiently so I know extra fuel is commin from somewhere. Wet is more of an add on, and dry is more of a "tuned" option, the way I look at it.

It depends on the car, some manufacturers have special bolt on fuel regulator add on devices which bump up fuel pressure only when the nitrous is sprayed. Those systems use the nitrous line pressure and convert it into the right amount of pressure needed to bump up the fuel pressure on the regulator, no ecu programming needed. Its possible you can adapt the system to any car, but my experience only lies with wet shot systems.

RRFPR for nitrous eh... hmm. I never thought of that haha

With the wet system I can control the amount of fuel going in via a metering jet, like a carburetor jet. The jets vary with bottle pressure, fuel pressure, ambient temperature, and however much power you want. I like this system b/c I dont have to get a "special ecm tune" for it to work. Yeah there is a lot more research and time to put into getting working right but im not relying on some other jackass' fuel map. Just my thoughts, you guys do what you want.

The wet EFI systems only need about 40 psi fuel pressure to operate correctly, mine is staying b/w 55-60 psi while spraying. I think the fuel pump is keeping up well with my setup.

Any new progress on this?

[Account_Deleted_T5M]

Regap your plugs at .023 to .025 stock gap is .028, pretty close to a t5 with basic mods, i trapped 8.9 @81mph in the 1/8th last year with a t5m with exhaust/tune/LSD

Awesome idea, i've always wanted to run a 50 shot on the t5, but i'm leaning more towards putting it on my 850 na

Well one of the benefits of running nitrous I would imagine is timing.

Unless you are using very small shots for the cooling effect, ignition timing needs to retarded when running nitrous, just like any other forced induction. I only had to dial back a few degrees though with the 75 shot I ran.

Nitrous is forced induction?

Yup

You are forcing more oxygen into the engine than it can "naturally" take in.

Hmm... I never knew that. Interesting info. But it is the colder of them in terms of heat and all.

Well the intake charge will be colder, but EGTs go up.

That, right now, is the most interesting thing I have heard in a long time. Is that dry or wet though. I wonder if that has any change on it even.

Not 100% sure but it should be the same. Wet or dry, there still should be the same amount of extra fuel to be paired with the nitrous. Wet just delivers the fuel from an external source (fuel solenoid run to the nitrous/fuel nozzle), whereas dry shots needs to have to fuel delivered by ecu tuning or a bump in fuel pressure when the nitrous sprays.

I have been informed by a friend it shouldn't matter. "Any development of energy makes heat."

I just got finished installing a NOS Pro Shot fogger system to the wagon. Haven't had a chance to make any runs with it to see if my times changed. I am waiting on the correct jets from NOS, but I just had to post this. It came off a 454 2 stage 500hp setup.

I am glad for ya. Hope it goes well.

WOW! I'm sorry, that was just my mind thinking. What are you nuts?

Ive run nitrous for years on my Volvo with no problems, if you know what you are doing, its a perfectly safe power adder.
